Epigenetic Reprogramming Restores Age-Related Vision Loss in Mice

Intriguing new research shows that it is possible to reverse age-related cellular dysfunction in vivo, specifically age-related vision loss. This suggests that modifying epigenetic expression is a powerful tool to counteract the damage of aging. The study published in Nature sought to reset the epigenome and DNA methylation patterns by expressing transcription factors, which help…

The Future of Healthcare Policies & Advocating for Reform with John Weeks

I had the honor to sit down and chat with a leader in our field regarding public health policy and advocacy, John Weeks. What a tremendous force behind the movement of bringing integrative and functional medicine to the forefront of healthcare – and with his 40 years of insight, it was a gift to get a sit-down to discuss where we are, and where we’re going – and how we can get there together. Listen in as we discuss how to create a collaborative and unified vision to light the path for the future of medicine – which will help patients, clinicians, and our entire community. The conversation left me invigorated and inspired and I’m confident it’ll do the same for you. Listen in, and let us know what you think by leaving a comment, review, or shooting us an email. Thanks as always, for the gift of your time. ~DrKF

Vitamin D Deficiency Increases Risk of Severe COVID Infection & Mortality

More research confirms that maintaining optimal vitamin D levels is extremely important for reducing the risk of infection with SARS Cov-2. A six-week observational study of 154 people published in Nature found that 97 percent of individuals with severe COVID-19 had vitamin D deficiency (mean concentration was 14 ng/mL) compared to 33 percent of people…

JAMA Article Attributes Dietary Benefits to Veganism But Misses Other Potential Contributors

The results from a newly-published trial on the effects of a dietary intervention in overweight adults are impressive: 14 lbs weight loss, increased insulin sensitivity, a 19.3 mg/dL reduction in total cholesterol, 15.4 mg/dL reduction in LDL cholesterol, and reduced fat distribution in the liver and muscles (associated with reduced risk for fatty liver and…

Nearly Half of New Cancer Therapies Approved by FDA Lack Randomized Clinical Trial Evidence & Only Prolong Life by Weeks

A large number of cancer therapies are approved by the FDA without randomized clinical trials and only increase median survival by 2.4 months, according to a new review article published in the Journal of the American Medical Association (JAMA). This may come as a surprise and disappointment considering the urgent goals of cancer research to…


Let’s Get Moving! WHO Updates Exercise Guidelines for All Ages

People of all ages, from kids to older adults, are encouraged to limit sedentary behavior and increase daily exercise, according to updated guidelines from the World Health Organization (WHO). These guidelines, which replace 2010 WHO recommendations, highlight the importance of combining aerobic plus strength training, and include guidance for pregnancy, postpartum women, and individuals with…


Polyphenols in Green Tea, Chocolate and Other Foods May Protect Against COVID

Some of our favorite polyphenol-rich foods, including green tea, muscadine grapes, cacao, and dark chocolate appear to block an enzyme in the SARS-CoV-2 virus, inhibiting its replication. A docking simulation and in vitro study published in Frontiers in Plant Science found that these flavan-3-ol and proanthocyandin-containing foods can block and bind the function of this enzyme, or protease, which…


Melatonin May Offer Significant Protection from COVID Infection, and especially for African Americans

Supplementing with melatonin may decrease the likelihood of contracting COVID, particularly among African Americans. Researchers analyzed data from an observational study of over 26,000 people from a COVID-19 registry at the Cleveland Clinic Health System and found that melatonin use is associated with a 52% reduced likelihood of a positive SARS-CoV-2 test in African Americans.…


Two Mechanisms Potentially Improving Acquired Immunity to COVID-19: The Common Cold and Breastmilk

People who have been exposed to a seasonal “common cold” may experience less severe COVID-19 symptoms. While we’ve discussed this topic previously, a study from the Journal of Clinical Investigation reports the first clinical evidence of cross reactivity with the common cold and COVID. This is due to previous immune responses against the four endemic…
