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…

Are You Nutritionally Prepared? Protect Your Body and Mind This Cold and Flu Season

Judging from the way 2020 has shaped up, this winter season may be like no other we’ve experienced before. Metabolic Maintenance, our sponsor this month, tells us about the mood and immune-boosting nutrients we need to have on hand for an unprecedented cold season. I have a long history with this family-owned company, going back to my days as a resident at Metametrix Clinical Laboratory. They make high-quality, novel therapeutics that I trust and use in my practice routinely. I especially like their vitamin D, zinc, and antioxidants. Don’t get caught unprepared for illness this winter. Shore up your immune defenses early so you can have a fun, safe, and healthy winter season!

Episode 69: Sponsored | Telomere Integrity: What Clinicians Need to Know with Dr. Joseph Raffaele

Sponsored |The Best Biomarker of Aging: What Clinicians Need to Know

I am particularly fascinated by new advances in testing biological age and how these biomarkers relate to disease risk. My podcast guest today is Dr. Joseph Raffaele MD, a leading expert, researcher, and clinician on the topic of biological aging and telomeres. We talked last year on New Frontiers, and I’m psyched to continue the conversation!

This time, Dr. Raffaele and I explore the various tests he uses to determine physiological age and disease risk, and go big into how senescent T cells and infections, such as cytomegalovirus, increase COVID-19 risk, particularly in a younger, seemingly healthy population. You’re going to love this enticing convo on the role of aging as it relates to disease and COVID-19 risk, and might find some great take-away clinical pearls to use in your own practice. Settle in, this is a good one, and let me know what you think by leaving a review or comment! ~DrKF

Stage IV Cancer: Dr. Patrick Hanaway’s Personal Experience with Functional & Integrative Modalities

Is it fair that I say – yet again – that this was my best conversation this year? My most deeply personal, honest, heartfelt, love-filled, scientific, evidence-informed (and pearl-ladened) conversation on cancer and recovery? Well, Dr. Patrick Hanaway, MD is a mentor, a colleague, a friend, and an amazing guy. His journey as a leader in functional medicine through stage IV laryngeal cancer and his embrace of a metabolic approach was profound.
