Characterizing the potential health effects of exposure to risk factors such as red meat consumption is essential to inform health policy and practice. Previous meta-analyses evaluating the effects of red meat intake have generated mixed findings and do not formally assess evidence strength. Here, we conducted a systematic review and implemented a meta-regression—relaxing conventional log-linearity assumptions and incorporating between-study heterogeneity—to evaluate the relationships between unprocessed red meat consumption and six potential health outcomes. We found weak evidence of association between unprocessed red meat consumption and colorectal cancer, breast cancer, type 2 diabetes and ischemic heart disease. Moreover, we found no evidence of an association between unprocessed red meat and ischemic stroke or hemorrhagic stroke. We also found that while risk for the six outcomes in our analysis combined was minimized at 0?g unprocessed red meat intake per day, the 95% uncertainty interval that incorporated between-study heterogeneity was very wide: from 0–200?g?d?1. While there is some evidence that eating unprocessed red meat is associated with increased risk of disease incidence and mortality, it is weak and insufficient to make stronger or more conclusive recommendations. More rigorous, well-powered research is needed to better understand and quantify the relationship between consumption of unprocessed red meat and chronic disease.

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, we’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%.

We’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.

It’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!

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!

NAD+ Restoration Therapy

NAD+ Restoration Therapy

Risk-Benefit Analysis

NAD+ is a pyridine nucleotide found in all living cells. It plays an important role in energy metabolism and is a substrate for several enzymes (including those involved in DNA repair). NAD+ levels may decline markedly with age (Massudi et al., 2012Clement et al., 2019Zhu et al., 2011) and restoring those levels to a youthful state is believed to have beneficial effects on health and longevity. 

Key Questions 

This analysis seeks to answer the following questions:

  • Which health and/or longevity benefits result from raising NAD+ levels in humans? 
  • Which risks are involved in raising NAD+ levels (general and method-specific)?
  • What are the potential risk mitigation strategies?
  • Which method or combination of methods is most effective in raising NAD+ levels?
  • Which of the available methods are safe for use? 
  • What is the best therapeutic protocol available at the moment?



Risks: this risk is low (less than 10 cases for 100,000 patient years), but the risk of metformin-induced lactic acidosis (MALA) increases in certain situations where both the plasma levels of metformin are increased and lactate clearance is impaired.[6]
