‘Psychedelics renaissance’: new wave of research puts hallucinogenics forward to treat mental health | Mental health | The Guardian


The Smiles Trial: Nutrition for Depression | Ideal Nutrition

Each food, beverage, or mixed dish receives a final Food Compass score ranging from 1 (least healthy) to 100 (most healthy). The researchers identified 70 or more as a reasonable score for foods or beverages that should be encouraged. Foods and beverages scoring 31-69 should be consumed in moderation. Anything scoring 30 or lower should be consumed minimally.

Across major food categories, the average Food Compass score was 43.2.

The lowest scoring category was snacks and sweet desserts (average score 16.4).
The highest scoring categories were vegetables (average score 69.1), fruits (average score 73.9, with nearly all raw fruits receiving a score of 100), and legumes, nuts, and seeds (average score 78.6).
Among beverages, the average score ranged from 27.6 for sugar-sweetened sodas and energy drinks to 67 for 100% fruit or vegetable juices.
Starchy vegetables scored an average of 43.2.
The average score for beef was 24.9; for poultry, 42.67; and for seafood, 67.0.


Fasting and Exercise Induce Changes in Serum Vitamin D Metabolites in Healthy Men

Increases in 24,25(OH)2D3 and 3-epi-25(OH)D3 levels imply that fasting stimulates vitamin D metabolism. The effects of exercise on serum vitamin D metabolites, which are most pronounced after fasting and in subjects with serum 25(OH)D3 above 25 ng/mL, support the notion that fasting and exercise augment vitamin D metabolism.


Frontiers | The Effects of Daytime Psilocybin Administration on Sleep: Implications for Antidepressant Action | Pharmacology

Psilocybin (O-phosphoryl-4hydroxy-N, N-dimethyltryptamine) and its active metabolite psilocin (4-hydroxy-N, N-dimethyltryptamine) are the main psychoactive components of psychedelic mushrooms. In the central nervous system, psilocin acts as an agonist of serotonergic 5-HT1A and 5-HT2A/C receptors, leading to altered states of consciousness in humans (Tyls et al., 2014). Psilocybin doses of 0.04–0.43 mg/kg cause alterations in perception, cognition, and emotions, while also eliciting long-term changes in well-being and mood in both healthy and psychiatric subjects (Dos Santos et al., 2016; Kor?ák et al., 2019; Barrett et al., 2020). These long-lasting positive changes lead to an exploration of the therapeutic potential of psychedelics as well as the mechanisms underlying this potential. Because of its general safety, intermediate duration of action, and therapeutic potential in several neuropsychiatric disorders, psilocybin is currently the most intensely studied psychedelic in clinical trials (Sewell et al., 2006; Grob et al., 2011; Stebelska, 2013; Dos Santos, 2014).

Overall, there has been an increasing preclinical (Catlow et al., 2013; Baumeister et al., 2014) and clinical (Carhart-Harris et al., 2016; Bogenschutz and Ross, 2018) evidence for the antidepressant potential of psilocybin. Although exact mechanisms are currently unknown, it is generally believed to be attributed to either a direct action on 5-HT receptors or the psychological effects of acute intoxication (Carhart-Harris and Goodwin, 2017). It has been shown that serotonergic psychedelics including psilocybin via 5-HT2A receptors promote neuroplasticity (Ly et al., 2018), a fundamental mechanism of neuronal adaptation that is disrupted in depression (Carhart-Harris and Goodwin, 2017) and restored by antidepressant treatments including selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs) or electroconvulsive therapy (ECT) (Hayley and Littlejohn, 2013).

COVID-19 pandemic has been linked with six unhealthy eating behaviors: Study shows a slight increase in eating disorders, one of the deadliest psychiatric health concerns — ScienceDaily

Eat healthy:

A new probe into the lingering impacts of the COVID-19 pandemic revealed correlations to six unhealthy eating behaviors, according to a study by the University of Minnesota Medical School and School of Public Health. Researchers say the most concerning finding indicates a slight increase or the re-emergence of eating disorders, which kill roughly 10,200 people every year — about one person every 52 minutes.


Exercise and nutrition regimen benefits physical, cognitive health: 12-week double-blind control trial in 148 Air Force airmen — ScienceDaily

“Researchers studied the effects of a 12-week exercise regimen on 148 active-duty Air Force airmen, half of whom also received a twice-daily nutrient beverage that included protein; the omega-3 fatty acid, DHA; lutein; phospholipids; vitamin D; B vitamins and other micronutrients; along with a muscle-promoting compound known as HMB. Both groups improved in physical and cognitive function, with added gains among those who regularly consumed the nutritional beverage, the team reports.”


Health and disease markers correlate with gut microbiome composition across thousands of people | Nature Communications

“We identify major axes of taxonomic variance in the gut and a putative diversity maximum along the Firmicutes-to-Bacteroidetes axis. Our analyses reveal both known and unknown associations between microbiome composition and host clinical markers and lifestyle factors, including host-microbe associations that are composition-specific. These results suggest potential opportunities for targeted interventions that alter the composition of the microbiome to improve host health.”

Saturated Fats and Health: A Reassessment and Proposal for Food-Based Recommendations | JACC: Journal of the American College of Cardiology

Dave Asprey seems to do a good job at explaining what this study means:

“Something truly epic happened today that is going to change what you eat for years to come. Truly epic. The Journal of the American College of cardiology published a groundbreaking paper today admitting something that you already knew if you had been on the Bulletproof Diet for the last 10 years. (Yes, I am feeling slightly vindicated after receiving so much resistance after writing The Bulletproof Diet, which eventually helped people lose about 1,000,000 pounds!)This new paper, which uses data from studying 135,000 people overtime, finds:-Saturated fat from meat and dairy do not cause an increase in cardiovascular disease, and reduce stroke risk.-Polyunsaturated fats increase risk of cardiovascular disease.-Different fats do different things-Cutting saturated fat does not reduce death rate-the 25% of people eating the highest saturated fat intake (about ∼14% of calories) had lower risk of stroke-Only 5% of fat should be polyunsaturated for lowest death. This is effectively a deathblow to vegan and plant-based practices, which make people sick over time because they contain almost all polyunsaturated fats. Itâ€s one reason I got sicker when I was a vegan. (It takes 2 years to replace half your cell membrane fats when you change your diet.)”

Niacin Increases NAD+ Significantly in Human Trial | Lifespan.io

The results of a new human trial using niacin shed new light on its role in NAD+ biology [1].

The trial participants were given a steadily increasing dose of niacin, starting at 250 mg/day to 750-1000 mg/day over a 4-month period, then a 10-month follow-up treatment period. The participants were organized into a study group of individuals with mitochondrial myopathy and a control group of healthy age-matched people consisting of two healthy people for each patient with mitochondrial myopathy. All the study participants were placed on the same niacin supplementation regimen.

The researchers report that niacin treatment increased muscle NAD+ levels by 1.3-fold at 4 months and 2.3-fold after 10 months in the study group.

Consumer trends during Covid-19

Some interesting and somewhat encouraging news from the Woolworths CEO today via his email updates during Covid-19 show some interesting trends in consumer spending on food and vitamins during this time.

To quote from his email:

We are becoming healthier and more adventurous in our cooking
While the slow cooking movement continues, weâ€re also becoming increasingly adventurous. Ingredients such as cardamom, saffron and dried sesame seeds have doubled in sales. Roasted peppers are up 65%, Asian and hot chilli sauces are both up 40% and capers are up 35%.

Weâ€re also well into soup season. What’s interesting this year is the explosive growth of dried soup mix packets (up 200%) as people make more warming soup at home.

Itâ€s also interesting to see customers think about their health, with a big rise in vitamin sales, plus ground ginger and turmeric sales up 120% and sauerkraut up 76%. On a related topic, sales of cough and cold products are much lower this year compared to last year.”

This is encouraging and hopefully a sign that the general population is starting to become more interested in preparing fresh meals rather than fast food, and hopefully the rise in vitamins and other beneficial products is a sign that people are starting to see value in improving their health and eating better.

It’s pretty clear that the more fit and healthy you are and the better you eat, the less likely you are to contract Covid-19 and, less likely to have severe complication if you do. We have been keeping an eye on developments and have been hoping that the silver lining from all of this may be a new focus on health and well-being.

So please ensure you take some time out of your busy life to focus on whats really important, your life! We at Health Hacker wish all of you good health and encourage you to keep exploring and trying to improve your diet and lifestyle as much as possoble. Remember, something is better than nothing so start on somethign today!

Part 1: My COVID-19 update – April 1st – Dr David A Sinclair

“Itâ€s April 1st, 2020. If only the headlines were a joke. Our nationâ€s leaders will soon be faced with a difficult choice. Hunker down for another four months and wreck the economy or let people out in two months and kill an additional hundred thousand people.

Professor Samir Bhatt, Senior Lecturer at the Imperial College of London, and his colleagues calculate that, globally, up to 43 million people have been infected with SARS-CoV-2. They predict that if weâ€d gone about our normal lives, COVID-19 would have caused 7 billion infections and 40 million deaths this year. Shielding only the elderly may have halved the number of deaths, a strategy the UK initially entertained, but health systems would have been overwhelmed, so that tactic was largely abandoned.

Based on the advice of professional epidemiologists, most nations have adopted a stretch-it-out and hope it doesnâ€t return strategy. It seems to be working so far. Rates of new cases are declining in Europe and the US. If the current suppression strategies are sustained, then 38.7 million lives globally will be saved this year, the epidemiologists at the Imperial College calculate. 

But epidemiologists arenâ€t economists. We can not stay home for the rest of the year – the economic impact would be too high. We are three weeks into the shutdown and already factories are ceasing production, brick-and-mortar retail stores and restaurants are closed, unemployment spikes are unprecedented, commodity prices have plunged, and a wave of loan defaults is expected.

A colleague on a global pandemic response panel tells me the panelâ€s best estimate is that the US economy will rebound rapidly, but only if the nation returns to work in 60 days. After that, itâ€s anyoneâ€s guess. No one, not even the experts, are willing to estimate the full economic impact of COVID-19. It will depend on how long it takes to get back to work and how many times we will be sent back home.”


Estimating clinical severity of COVID-19 from the transmission dynamics in Wuhan, China | Nature Medicine

As of 29 February 2020 there were 79,394 confirmed cases and 2,838 deaths from COVID-19 in mainland China. Of these, 48,557 cases and 2,169 deaths occurred in the epicenter, Wuhan. A key public health priority during the emergence of a novel pathogen is estimating clinical severity, which requires properly adjusting for the case ascertainment rate and the delay between symptoms onset and death. Using public and published information, we estimate that the overall symptomatic case fatality risk (the probability of dying after developing symptoms) of COVID-19 in Wuhan was 1.4% (0.9–2.1%), which is substantially lower than both the corresponding crude or naïve confirmed case fatality risk (2,169/48,557 = 4.5%) and the approximator1 of deaths/deaths + recoveries (2,169/2,169 + 17,572 = 11%) as of 29 February 2020. Compared to those aged 30–59 years, those aged below 30 and above 59 years were 0.6 (0.3–1.1) and 5.1 (4.2–6.1) times more likely to die after developing symptoms. The risk of symptomatic infection increased with age (for example, at ~4% per year among adults aged 30–60 years).


Dietary Intakes of Minerals, Essential and Toxic Trace Elements for Adults from Eragrostis tef L.: A Nutritional Assessment

“This study analysed the contents of thirty-six mineral and trace elements in teff (Eragrostis tef L.) grains. What is more, dietary intakes were calculated. Inductively coupled plasma mass spectrometry (ICP-MS) was used to assess mineral and trace element contents. Consequently, the appropriate Recommended Dietary Allowance (RDA) or adequate intake (AI), and provisional tolerable weekly intake (PTWI) or provisional tolerable monthly intake (PTMI) values for adults were determined according to the Food and Agriculture Organization/World Health Organization (FAO/WHO) and Institute of Medicine (IOM) regulations. Teff is a significant contributor to RDAs and AIs for females in the following order: Mn > Cu > Zn ≥ Mg > Fe ≥ P and Ca. For males, teff contributes in the order, Mn > Cu > Fe > Zn ≥ P ≥ Mg > and Ca. The concentration of arsenic (65.9 µg/kg) in brown teff originating in Bolivia exceeded the average acceptable value set by Reg. No. 1881 of 6–50 µg/kg in cereals consumed in the EU. The PTWIs or PTMIs for Al, Cd, Sn and Hg were all under 7%, which is below the limits of toxic element intake related to the body weight of 65 kg for adult females and 80 kg for males, set by the FAO/WHO. Teff grains can be recommended as a valuable and safe source of minerals and trace elements.”

Finding good food

I visited my local https://thesourcebulkfoods.com.au/ store at Rhodes the other day and found some great products. Among them was Kakadu plum powder and grass fed bone broth powder. The owner of the store and staff were very nice and very helpful. If you are looking for ingredients for your healthy meals then this is one good place to start. They have stores all around Australia and in some other regions as well and each seems to be owned by individuals or families under a franchise model. Each franchise also seems to have a fair bit of flexibility around sourcing ingredients so don’t be afraid to ask for something if it’s not already in store.

I will keep you up to date on new findings, please let us know if you find any places to get great quality ingredients.

Natural Products and Their Bioactive Compounds: Neuroprotective Potentials against Neurodegenerative Diseases

In recent years, natural products, which originate from plants, animals, and fungi, together with their bioactive compounds have been intensively explored and studied for their therapeutic potentials for various diseases such as cardiovascular, diabetes, hypertension, reproductive, cancer, and neurodegenerative diseases. Neurodegenerative diseases, including Alzheimerâ€s disease, Huntingtonâ€s disease, Parkinsonâ€s disease, and amyotrophic lateral sclerosis are characterized by the progressive dysfunction and loss of neuronal structure and function that resulted in the neuronal cell death. Since the multifactorial pathological mechanisms are associated with neurodegeneration, targeting multiple mechanisms of actions and neuroprotection approach, which involves preventing cell death and restoring the function to damaged neurons, could be promising strategies for the prevention and therapeutic of neurodegenerative diseases. Natural products have emerged as potential neuroprotective agents for the treatment of neurodegenerative diseases. This review focused on the therapeutic potential of natural products and their bioactive compounds to exert a neuroprotective effect on the pathologies of neurodegenerative diseases.

Recent studies on anti-aging compounds with Saccharomyces cerevisiae as a model organism – ScienceDirect

Extension of lifespan and amelioration of aging-associated phenotypes have been targets of many studies. Some of the established methods of increasing lifespan including dietary restriction and genetic manipulation are difficult to apply to humans, and their side effects are hard to predict. For that reason, it is important to discover compounds that can mimic the anti-aging actions or induce lifespan extension through different metabolisms within the cell. Here we summarize the recent studies to test various types of compounds and materials using budding yeast that show potential anti-aging effects.

Clinical features of patients infected with 2019 novel coronavirus in Wuhan, China – ScienceDirect

“By Jan 2, 2020, 41 admitted hospital patients had been identified as having laboratory-confirmed 2019-nCoV infection. Most of the infected patients were men (30 [73%] of 41); less than half had underlying diseases (13 [32%]), including diabetes (eight [20%]), hypertension (six [15%]), and cardiovascular disease (six [15%]). Median age was 49·0 years (IQR 41·0–58·0). 27 (66%) of 41 patients had been exposed to Huanan seafood market. One family cluster was found. Common symptoms at onset of illness were fever (40 [98%] of 41 patients), cough (31 [76%]), and myalgia or fatigue (18 [44%]); less common symptoms were sputum production (11 [28%] of 39), headache (three [8%] of 38), haemoptysis (two [5%] of 39), and diarrhoea (one [3%] of 38). Dyspnoea developed in 22 (55%) of 40 patients (median time from illness onset to dyspnoea 8·0 days [IQR 5·0–13·0]). 26 (63%) of 41 patients had lymphopenia. All 41 patients had pneumonia with abnormal findings on chest CT. Complications included acute respiratory distress syndrome (12 [29%]), RNAaemia (six [15%]), acute cardiac injury (five [12%]) and secondary infection (four [10%]). 13 (32%) patients were admitted to an ICU and six (15%) died. Compared with non-ICU patients, ICU patients had higher plasma levels of IL2, IL7, IL10, GSCF, IP10, MCP1, MIP1A, and TNFα.”


Novel coronavirus 2019 (2019 n-CoV) – Fact sheets

What is a coronavirus?
Coronaviruses are a large family of viruses, some cause illness in humans, and others cause illness in animals, such as bats, camels, and civets. Human coronaviruses cause mild illness, such the common cold.

Rarely, animal coronaviruses can evolve to infect and spread among humans, causing severe diseases such as Severe Acute Respiratory Syndrome (SARS) which emerged in 2002, and Middle East Respiratory Syndrome (MERS) which emerged in 2012.

A novel coronavirus (2019-nCoV) is a new strain of coronavirus that has not been previously identified in humans.

What is 2019 novel coronavirus?
There is a new coronavirus affecting people who have recently been in the city of Wuhan, China. There is much more to learn about how it is spread, its severity, and other features associated with 2019-nCoV, and investigations are ongoing. At the moment, this coronavirus is called ‘novel coronavirus 2019†or ‘2019-nCoVâ€.

Outbreaks of a novel coronavirus infections among people are always a public health concern. There is growing evidence that 2019-nCoV can spread from person to person in the community and in health care settings. There have been cases of 2019-nCoV reported in several Asian and other countries including Australia. The situation is evolving rapidly.

What are the symptoms?
Most case-patients have had fever, cough, and shortness of breath, with further evidence of pneumonia (chest infection).

Further investigation is required to assess whether there are undetected asymptomatic or mildly symptomatic cases.

How is it spread?
Early reports indicated that most of the cases had prior contact with a seafood and live animal market, suggesting an animal source of the outbreak. However, more recently, human to human transmission has been reported.

Further investigation is underway to confirm and describe the mode of transmission from animal sources, and the risk of human-to-human transmission.

Human to human transmission is most likely to be through direct contact with infectious patients, by respiratory droplets and by fomites (contaminated objects and surfaces), as is seen with other coronavirus infections including SARS and MERS.

Who is at risk?
People who are living or travelling to affected areas or who have had contact with other cases may be at risk of catching the disease. People with underlying illnesses that make them more vulnerable to respiratory disease, including those with diabetes, chronic lung disease, pre-existing kidney failure, people with suppressed immune systems and the elderly may be at a higher risk.

How is it prevented?
Itâ€s likely that general prevention measures used for other coronavirus infections will also prevent infection with 2019-nCoV.

The World Health Organization (WHO) recommends measures to reduce the general risk of acute respiratory infections while travelling in or from affected areas by:

avoiding close contact with people suffering from acute respiratory infections;
frequent hand-washing, especially after direct contact with ill people or their environment;
avoiding close contact with live or dead farm or wild animals;
travellers with symptoms of acute respiratory infection should practice cough etiquette (maintain distance, cover coughs and sneezes with disposable tissues or clothing, and wash hands).
Travellers to China are already advised not to visit live bird and animal markets, including ‘wet†markets, due to the risk of avian influenza.

There is currently no vaccine to prevent 2019-nCoV infections.

What should I do if I become unwell after travel in China?
If you become ill or feel unwell while travelling in China, you should not wait until you arrive back in Australia to seek medical assistance. Instead you should see a doctor or go to the local emergency department.

If you return from travel to China and feel unwell you should see your doctor or go to the emergency department to work out why you are ill, and you should mention your travel to China. Call ahead and explain that you might have been exposed to the novel coronavirus so that the doctor can make arrangements to see you quickly and safely.

How is it diagnosed?
Infection with 2019-nCoV is diagnosed by finding evidence of the virus in respiratory samples such as swabs from the throat or fluid from the lungs. Testing for 2019-nCoV is done in public health laboratories.

How is it treated?
There is currently no specific treatment for people who are sick with 2019-nCoV but general supportive medical care in hospital can be life-saving.

What is the public health response?
As of 23 January 2020, in Australia procedures to prevent the local spread of 2019-nCoV have been put in place.

Public health unit staff will investigate all cases to find out how the infection occurred, identify other people at risk of infection, implement control measures and provide other advice.

Kynurenine pathway, NAD+ synthesis, and mitochondrial function: Targeting tryptophan metabolism to promote longevity and healthspan – ScienceDirect

• The kynurenine pathway has recently been identified as a promising target to increase healthy longevity.

• Targeted inhibition of kynurenine pathway activity may alleviate several pathological conditions and promote healthspan.

• Changes to the production and recycling of NAD+ is a likely mediator of the beneficial effects of kynurenine pathway interventions.

• Mitochondrial function and dynamics represent NAD+-dependent processes downstream of kynurenine metabolism that may mediate benefits during aging.


Aging and Caloric Restriction Modulate the DNA Methylation Profile of the Ribosomal RNA Locus in Human and Rat Liver

“We confirm previous findings, showing age-related hypermethylation, and describe, for the first time, that this gain in methylation also occurs in human hepatocytes. Furthermore, we show that age-related hypermethylation is enhanced in livers of rat upon CR at two and 10 months, and that at two months a trend towards the reduction of rRNA expression occurs. Collectively, our results suggest that CR modulates age-related regulation of methylation at the rDNA locus, thus providing an epigenetic readout of the pro-longevity effects of CR.”

Resveralogues: From Novel Ageing Mechanisms to New Therapies? – Abstract – Gerontology – Karger Publishers

“For much of the 20th century the ageing process was thought to be the result of the interplay of many different biological processes, each with relatively small effects on organismal lifespan. However, this model is no longer tenable. Rather it seems a few biological mechanisms, including nutrient sensing, telomere attrition and cellular senescence, mediate large effects on health and longevity. Biogerontology may have suffered from initial delusions of complexity. However, we argue that it is premature to assume either that the list of biological processes influencing lifespan is now comprehensive or that these mechanisms act independently of each other.”

Zinc transporters maintain longevity by influencing insulin/IGF‐1 activity in Caenorhabditis elegans – Novakovic – – FEBS Letters – Wiley Online Library

“Adequate dietary intake of essential metals such as zinc is important for maintaining homeostasis. Abnormal zinc intake in Caenorhabditis elegans has been shown to increase or decrease normal lifespan by influencing the insulin/IGF‐1 pathway. Distribution of zinc is achieved by a family of highly conserved zinc transport proteins (ZIPT in C. elegans). This study investigated the role of the zipt family of genes and show that depletion of individual zipt genes results in a decreased lifespan”

Study finds losing a night of sleep may increase blood levels of Alzheimer’s biomarker | EurekAlert! Science News

“A preliminary study by researchers at Uppsala University has found that when young, healthy men were deprived of just one night of sleep, they had higher levels of tau – a biomarker for Alzheimer’s disease – in their blood than when they had a full, uninterrupted night of rest. The study is published in the medical journal Neurology.”


Biologists identify pathways that extend lifespan by 500%

“Because alteration of the IIS pathways yields a 100 percent increase in lifespan and alteration of the TOR pathway yields a 30 percent increase, the double mutant would be expected to live 130 percent longer. But instead, its lifespan was amplified by 500 percent.

“Despite the discovery in C. elegans of cellular pathways that govern aging, it hasn’t been clear how these pathways interact,” said Hermann Haller, M.D., president of the MDI Biological Laboratory. “By helping to characterize these interactions, our scientists are paving the way for much-needed therapies to increase healthy lifespan for a rapidly aging population.””


What lifestyle changes will help me live longer and healthier?

We’ve previously spoken about how we might introduce foods and supplements to our diet to improve health span and lifespan. Here we explore activities and other therapies that show potential in living healthier and longer. We also explore things you perhaps should stop doing to improve health and longevity.

Mitochondrial support

Mitochondria are organelles, basically, little functional units within cells, much like an organ is to our body. They provide power to our cells by delivering ATP to the cells and are thought to once be free-ranging bacteria. It is thought that the break down of mitochondrial function is one of, if not the main contributor to aging.

Which supplements can help me live longer and healthier?

There are two main ways to provide the nutrients and myriad of compounds that can help your body operate at its best and improve both lifespan and healthspan. One is to include foods and adjust your diet, however, we don’t always have that option to due various constraints such as taste and lifestyle. This is where supplements step in to provide the essential components of those foods as extracts or via chemical synthesis.

Here we explore the supplements you can incorporate into your lifestyle to get those identified goodies that keep us healthy for longer. This is the second of three articles on increasing health and life span. Our article on foods will have some overlap with this article as in many cases supplements are a derivative of food.
As always, we do our best to validate any information presented however, we cannot guarantee the accuracy of statements made here and does not constitute medical advice. Please check with your healthcare professional before making changes to your diet and lifestyle.
We have included as many references as possible to back our claims and for you to click into to investigate further for yourself. We encourage anyone seeking to improve their health via supplementation to take some time to research it’s effects, side effects and dosage.

Eating to live…longer and healthier.

There are two main ways to provide the nutrients and the myriad of compounds that can help your body operate at its best and improve both lifespan and healthspan. One is to use supplements and the other is to do it via food in our diet.

Here, in the first of our three part series on direct action for longevity, we explore the foods you can incorporate into your diet to get those identified goodies that keep us healthy for longer. We will also include herbs here as food as they require little to no handling to be beneficial and can be consumed as a food. Some of this is known via human clinical trial while some may be a mix of anecdotal use or animal studies. In all cases we take a can’t hurt, might help, approach and will either call out or exclude anything showing any risk of harm.

It’s important to note that, while all care is taken, we cannot guarantee the accuracy of this information and you should consult your health care professional before making changes in your diet and lifestyle.

3 Ways We May Be Able To Reverse Aging, From A Microbiologist

“Organic foods aren’t held with gloves. They’re a little bit more stressed out. The more stressed out your food is the brighter colors they’ll have because they’re producing these colors as a defense,” Sinclair explains.

Those bright colors, he adds, are indicators that the food has produced “xenohormesis molecules,” which activate our sirtuins that give our bodies an extra boost for longevity.


Fisetin | | LEAF

“Fisetin, like many plant polyphenols, is known to have antioxidant properties and demonstrates the specific biological activity of protecting functional macromolecules against stress, resulting in a benefit to cellular cytoprotection. It is also known to have anti-inflammatory, chemopreventive, and chemotherapeutic properties.

Finally, more recently, it has also shown promise as a senolytic, a compound that encourages aged or damaged senescent cells to destroy themselves rather than lingering in the body and contributing to the chronic, age-related inflammation known as “inflammaging”, which is associated with a wide range of age-related diseases.

Since fisetin has a good safety profile, Mayo Clinic followed these mouse studies by launching three trials to see if the compound is effective for humans.”

Role of High‐Density Lipoproteins in Cholesterol Homeostasis and Glycemic Control | Journal of the American Heart Association

Emerging evidence (summarized in Table) indicates that HDL‐ and apoA‐I–targeted therapies are a potential option for conserving residual β‐cell function and improving insulin sensitivity in patients who are progressing toward, or have already developed, T1DM and T2DM. The recent failures of HDL‐raising agents in cardiovascular clinical outcome trials highlight the need to develop novel and innovative HDL‐targeted approaches to achieve these goals. Elucidating the mechanism(s) underlying the antidiabetic functions of HDLs and apoA‐I will also provide opportunities to identify and develop new HDL‐targeted therapies for diabetes mellitus. Achievement of these goals could be particularly advantageous for patients with T1DM for whom treatment options are currently limited to insulin replacement therapy, and for patients with T2DM that are refractory to currently available therapies.

The Vagus Nerve is Key to Well-Being | Elemental

“The vagus nerve, also called the “10th cranial nerve,” is the longest, largest, and most complex of the cranial nerves, and in some ways itâ€s also the least understood. Experts have linked its activity to symptom changes in people with migraine headaches, inflammatory bowel disease, depression, epilepsy, arthritis, and many other common ailments. The more science learns about the vagus nerve, the more it seems like a better understanding of its function could unlock new doors to treating all manner of human suffering.”

Why 80 Percent of New Year’s Resolutions Fail

A new year, and a new decade lay before us as we reach the end of 2019.

You’re inspired to start improving something about your health of life.

Don’t, well, more accurately do, but don’t do it for a new years resolution.

Do it because you are ready, do it because you’re done with the status quo, do it for your happiness, for your family.

Do it for any reason other than an arbitrary date with artificial importance projected upon it.

Changes are hard and habits are strong. It takes time and conviction to change so you need to be truly ready and you need to do it as soon as you can.

If you set yourself a new years resolution and fail you are likely to give up completely or revert back to comfort to relive the disappointment and depression that may follow a failed new years resolution.

Know that you have it in you to change without an arbitrary date. You can do it!



Effects of Intermittent Fasting on Health, Aging, and Disease | NEJM

“Evidence is accumulating that eating in a 6-hour period and fasting for 18 hours can trigger a metabolic switch from glucose-based to ketone-based energy, with increased stress resistance, increased longevity, and a decreased incidence of diseases, including cancer and obesity.”


Longevity protein SIRT6 also protects against fatty liver and fatty liver disease – Science Mission

“Fatty liver, or hepatic steatosis, which develops when the body produces too much fat or doesn’t metabolize fat efficiently enough, affects around 25% of the global population. Excess fat is stored in liver cells, where it accumulates and can cause fatty liver and other diseases.

In a study just published in the journal Cell Reports, researchers reveal for the first time that SIRT6, a protein involved in regulating many biological processes such as aging, obesity, insulin resistance, inflammation and metabolism, also plays a crucial role in burning and regulating liver fat metabolism.”


Age and life expectancy clocks based on machine learning analysis of mouse frailty | bioRxiv

“The identification of genes and interventions that slow or reverse aging is hampered by the lack of non-invasive metrics that can predict life expectancy of pre-clinical models. Frailty Indices (FIs) in mice are composite measures of health that are cost-effective and non-invasive, but whether they can accurately predict health and lifespan is not known. Here, mouse FIs were scored longitudinally until death and machine learning was employed to develop two clocks. ”

Frontiers | Intense Physical Exercise Induces an Anti-inflammatory Change in IgG N-Glycosylation Profile | Physiology

” Exercise is known to improve many aspects of human health, including modulation of the immune system and inflammatory status. It is generally understood that exercise reduces inflammation, but there are missing links in terms of understanding the mechanisms as well as the differences between exercise modalities. N-glycosylation of immunoglobulin G (IgG) and total plasma proteins was previously shown to reflect changes in inflammatory pathways, which could provide valuable information to further clarify exercise effects. In order to further expand the understanding of the relationship between physical activity and inflammation, we examined the effect of intense exercise, in the form of repeated sprint training (RST), on IgG and total plasma proteins N-glycosylation in combination with traditionally used inflammation markers: C-reactive protein (CRP), interleukin 6 (IL-6), and leukocyte count.

Chinese Herbal Medicine Formula Shenling Baizhu San Ameliorates High-Fat Diet-Induced NAFLD in Rats by Modulating Hepatic MicroRNA Expression Profiles

“Objective. The purpose of present study was to investigate the potential mechanism underlying the protective effect of Shenling Baizhu San (SLBZS) on nonalcoholic fatty liver disease (NAFLD) by microRNA (miRNA) sequencing. Methods. Thirty male Wistar rats were randomly divided into a normal control (NC) group, a high-fat diet (HFD) group, and an SLBZS group. After 12 weeks, the biochemical parameters and liver histologies of the rats were assessed. The Illumina HiSeq 2500 sequencing platform was used to analyse the hepatic miRNA expression profiles. Representative differentially expressed miRNAs were further validated by qRT-PCR. The functions of the differentially expressed miRNAs were analysed by bioinformatics. Results. Our results identified 102 miRNAs that were differentially expressed in the HFD group compared with the NC group. Among those differentially expressed miRNAs, the expression levels of 28 miRNAs were reversed by SLBZS administration, suggesting the modulation effect of SLBZS on hepatic miRNA expression profiles. The qRT-PCR results confirmed that the expression levels of miR-155-5p, miR-146b-5p, miR-132-3p, and miR-34a-5p were consistent with those detected by sequencing. Bioinformatics analyses indicated that the target genes of the differentially expressed miRNAs reversed by SLBZS were mainly related to metabolic pathways. Conclusion. This study provides novel insights into the mechanism of SLBZS in protecting against NAFLD; this mechanism may be partly related to the modulation of hepatic miRNA expression and their target pathways.”

DNA Testing

Have you considered getting your DNA sequenced? Wonder what kind of information you could expect out of it?

I recently got my DNA sequenced at Self Decode and the results are in! Let’s take a look at whats in there and how I might be able to use it to improve my health and lifespan.

The introductory report shows me a high level overview of things I may want to dig deeper into.

Now, what does this mean and what can I do about it?

Typical risk of vit. k deficiency so, not much needed to be done here
Mostly typical ability to convert beta-carotene to Vit. A. Nothing to see here.
Seemingly normal ability to process B12. Good news.
I know I have one of two MTFHR gene mutations so no surprises here on Folate. I supplement with MTHF or Methyl-Folate to make up for this.
Now, I don’t drink Coffee, nor do I drink and caffeinated drinks so, nothing to worry about here. Basically I can process caffeine more readily.
Need to keep an eye on food intake. I have recently started intermittent fasting and have reduce my sugar and dairy intake (see our post about miRNA’s in milk expressing mTOR and suppressing AMPK).
Mix results here meaning no real action needed except that I should possibly target power training.
Typical Lipid levels. Not better or worse, just your regular ability to process lipids.
I never considered that DNA may influence something like my levels of empathy. I guess this explains why I’ve started Health Hacker to help people live healthier and longer lives.
Look out Black Friday and Cyber Monday, here comes an impulse shopper!
Anxiety is something I’ve struggled with for most of my life. I employ multiple strategies to help with it including CBD and B3, along with Omega-3.

Along with the report are sources to NIH publications to back the assertions. You also get deeper reports on each of those subject areas including MTFHR, APOE, Mood, Cognitive, Essential Minerals, Vitamins, Sleep, Cardiovascular, Inflammation and Fitness. You also get a personalised blog that shows you articles related to SNPs in your results.

I’m not saying that this is the best DNA service but it’s the one I chose and this is what I got. It seems quite comprehensive and does a good job at explaining what it all means and how I can adjust my diet and lifestyle to account for deficiencies caused by gene mutations. If this is something you are interested in then it might be an option for you.

Mechanisms of Calorie Restriction: A Review of Genes Required for the Life-Extending and Tumor-Inhibiting Effects of Calorie Restriction

” We reviewed and discussed underlying mechanisms of CR from an aspect of CR genes. It should be stressed that the isoform specificity of FoxO transcription factors for longevity becomes apparent under CR conditions but not AL conditions. Npy and FoxO1 both play pleiotropic roles in aging and related disorders, depending on the nutritional state. As briefly described in Section 1 and Section 2, the life-extending effects of CR and reduced IGF-1 signaling are also sexually dimorphic. Genes associated with regulation of the aging process should be investigated carefully in a context-dependent manner, i.e., abilities of physiological adaptation for individuals against environmental challenges, particularly food shortage. “

Mitochondria: Exploring 5 Lifestyle Habits to Benefit Cell Health

In each of our cells are small energy generators called mitochondria. The health of our mitochondria determines the amount of adenosine triphosphate (ATP) they can produce from the calories we eat and oxygen we consume. Without robust mitochondria, cells cannot do as much work as theyâ€re capable of and we need them to do so we can stay healthy. To achieve higher levels of performance we must optimize our mitochondria, the powerhouse of our cells, to produce energy. Cell function isnâ€t always the first place biohackers and nootropics enthusiasts start because it is challenging to notice a subjective boost in our mitochondrial function. Whether we can detect enhanced mitochondria subjectively or not, the science is pretty clear that healthy mitochondria play a role in supporting all indicators of cognition, physical performance, and aging. In a series of comprehensive posts, we will introduce scientifically-backed lifestyle changes and nootropics that up-regulate your mitochondrial function. In our last post, we went over how to use light and temperature to boost mitochondria. Now letâ€s tackle 5 more lifestyle habits we can implement to achieve healthier mitochondria.

Maf1‐dependent transcriptional regulation of tRNAs prevents genomic instability and is associated with extended lifespan – Shetty – – Aging Cell – Wiley Online Library

Fundamental cellular mechanisms such as nutrient sensing, DNA damage response pathways, and cell cycle regulation influence the aging process. Studies have shown that the nutrient sensory kinase, mTOR (TOR in yeast), regulates lifespan in response to nutrient availability. The mTOR kinase forms two distinct protein complexes: TORC1 and TORC2. TORC1, which is inhibited by rapamycin, regulates cell growth, proliferation, and metabolism. It is well established that TORC1 promotes protein translation via phosphorylation of ribosomal protein S6 kinase and the eIF4E‐binding protein (BP; Zoncu, Efeyan, & Sabatini, 2011). The TORC2 branch is less studied; however, TORC2 also plays important roles in metabolism, cell survival, and proliferation (Zoncu et al., 2011). Although the involvement of the TORC1 pathway in lifespan regulation is conserved among many species (i.e., TORC1 inhibition extends lifespan), it is still unclear how this pathway affects multiple downstream stress and damage response mechanisms.


Measuring biological aging in humans: A quest – Ferrucci – – Aging Cell – Wiley Online Library

“The global population of individuals over the age of 65 is growing at an unprecedented rate and is expected to reach 1.6 billion by 2050. Most older individuals are affected by multiple chronic diseases, leading to complex drug treatments and increased risk of physical and cognitive disability. Improving or preserving the health and quality of life of these individuals is challenging due to a lack of well‐established clinical guidelines. Physicians are often forced to engage in cycles of “trial and error” that are centered on palliative treatment of symptoms rather than the root cause, often resulting in dubious outcomes. Recently, geroscience challenged this view, proposing that the underlying biological mechanisms of aging are central to the global increase in susceptibility to disease and disability that occurs with aging. In fact, strong correlations have recently been revealed between health dimensions and phenotypes that are typical of aging, especially with autophagy, mitochondrial function, cellular senescence, and DNA methylation. Current research focuses on measuring the pace of aging to identify individuals who are “aging faster” to test and develop interventions that could prevent or delay the progression of multimorbidity and disability with aging. Understanding how the underlying biological mechanisms of aging connect to and impact longitudinal changes in health trajectories offers a unique opportunity to identify resilience mechanisms, their dynamic changes, and their impact on stress responses. Harnessing how to evoke and control resilience mechanisms in individuals with successful aging could lead to writing a new chapter in human medicine.”


The strange case of AMPK and cancer: Dr Jekyll or Mr Hyde?† | Open Biology

“The AMP-activated protein kinase (AMPK) acts as a cellular energy sensor. Once switched on by increases in cellular AMP : ATP ratios, it acts to restore energy homeostasis by switching on catabolic pathways while switching off cell growth and proliferation. The canonical AMP-dependent mechanism of activation requires the upstream kinase LKB1, which was identified genetically to be a tumour suppressor. AMPK can also be switched on by increases in intracellular Ca2+, by glucose starvation and by DNA damage via non-canonical, AMP-independent pathways. Genetic studies of the role of AMPK in mouse cancer suggest that, before disease arises, AMPK acts as a tumour suppressor that protects against cancer, with this protection being further enhanced by AMPK activators such as the biguanide phenformin. However, once cancer has occurred, AMPK switches to being a tumour promoter instead, enhancing cancer cell survival by protecting against metabolic, oxidative and genotoxic stresses. Studies of genetic changes in human cancer also suggest diverging roles for genes encoding subunit isoforms, with some being frequently amplified, while others are mutated.”
