Dark Chocolate’s Health Benefits Include Skin Health
No website or blog on longevity medicine would be complete without a piece on aging skin, which includes UV-induced photodamage, loss of dermal matrix, and wrinkles. Of course, hormones, lifestyle, and sun exposure play a large role in how our skin ages, and we are covering those topics in other pieces. But I recently came across a series of articles highlighting the large beneficial effect of one of my favorite foods: dark chocolate!
Skin ages with the rest of our physiology, and there is an “intrinsic” aging which is inevitable, resulting from a rapid drop in collagen production, about a 28% drop in exfoliation, loss of subcutaneous fat, and other factors, all leading to skin that appears thinner and more translucent, and has lost strength and elasticity. However, photoaging, or “extrinsic” aging of the skin, is almost completely under our control. Extrinsic aging includes the wrinkles induced by UV light, the appearance of dark spots (uneven pigmentation), and some of the breakdown of the dermal matrix.
Cocoa has a long and interesting history as a human food. Growing research data has conclusively shown that cocoa phytochemicals (in the general class known as “flavonoids”) have clinically significant benefits on skin health and appearance. In fact, Cambridge University developed human trials showing that 7.5 grams of HIGH-QUALITY dark chocolate daily can alter the underlying skin structure of a 50-year-old to resemble someone in their 30s. They have spun off this research into a product that is heavily enriched in catechins and antioxidants, called “Esthechoc”. Other studies are referenced below, with the last one containing 54 references supporting the thesis that cocoa bioactive compounds do support and maintain skin health over time.
Cocoa’s Other Health Benefits
In addition to skin, cocoa benefits many other aspects of our physiology. Cocoa fat is mostly oleic oil (as in olive oil) and some palmitic and stearic acid. Some people on low-fat diets do need a small amount of these saturated fats since our microbiome is responsible for producing the small fats (like butyrate) that initiate our production of these longer-chain saturated fats, and our gut bacteria and fiber intake are known to be compromised. There are minerals present like magnesium, copper, iron, and potassium. One study showed that dark chocolate had more antioxidant power than any fruit tested. In addition, researchers have showed increased nitric oxide (reduces blood pressure and increases blood flow and oxygen delivery), reduction in oxidized LDL, and increased HDL. The flavanols can reduce insulin resistance as well.
How to Choose a Dark Chocolate
In general, there should be just a few ingredients; it requires only chocolate liquor or cocoa, a small amount of sugar, and cocoa butter to produce, and cocoa, not sugar, should be the first ingredient. It should be higher in cocoa, over 70%, and should NEVER contain milk and should NEVER say “alkali processed” or “Dutch-processed,” which deteriorates its antioxidant ability. Flavorings may be present, such as spices and herbs, and occasionally tiny amounts of lecithin, an emulsifier, are used, which is okay. Fairtrade and organic are best in terms of purity and quality of the beans and soil. Some examples of high-quality brands are Alter Ego, Pascha Chocolate, Antidote Chocolate, and Equal Exchange. There are many good brands and if you become a connoisseur you can subscribe to Bar and Cocoa, like my friend Alan, and receive several quality bars monthly from all over the world, but you’ll need to share! Keep in mind that one ounce of 70-80% dark chocolate will have around 170 calories, so for most of us, something will need to be “traded in” to make room!

What Is Zone 2 Training And Why Is It Important?
What if I offered you a pill that took your cellular age back ten to fifteen years? This pill also increases mitochondrial numbers (kind of like the number of battery chargers in our cells), increases overall available energy, improves metabolic flexibility, lowers resting heart rate, decreases blood pressure, and improves insulin resistance? This “pill” is yours for the taking, except we call it “zone 2 training”.

Your Immune System Reboot: Diet & Lifestyle
When the coronavirus SARS-co-v2, a devastating communicable disease, descended upon the global population in December 2019, it became clear early on that there was a wide spectrum of illness, ranging from almost nothing to diarrhea, severe pneumonia, stroke, and death. By May of 2020, it became even more clear that there are particular conditions (“comorbidities”) that markedly increase the disease severity and death rate, and that these conditions had in common an immune system dysfunction with the shared characteristic of chronic inflammation. We have learned that people with chronic inflammation have higher levels of furin and that furin acts as a facilitator to allow better binding of the viral spike protein to our ACE2 receptors. Harboring chronic inflammation turns us into something like Velcro, attracting more virus, secreting more furin, and allowing more severe disease states to evolve. Read more
Polypill vs. Treadmill: Walking Your Way to Optimal Health
My grandfather used to say “Exercise? I get plenty of exercise – pushing myself back from the dinner table every night!” Of course, he walked almost daily on the Coney Island boardwalk in the middle of the winter and lived well into his 90s, so this was really just a way to get a laugh from us.

Why We Age and Why Genomics?
In his masterful book “Lifespan: Why We Age- And Why We Don’t Have To” David Sinclair asks, “What if, in our 60’s, we weren’t fretting about leaving a legacy but beginning one? What if we didn’t have to worry that the clock was ticking? In fact, he makes the case that we are closer than you think to changing what “old age” looks like, feels like, performs like. David Sinclair is an optimist of course, but he’s also a Harvard professor and one of the most prolific researchers in the area of aging, or senescence. His lab has turned out paper after paper, building and transforming our understanding of the aging processes. Some of the things he has uncovered have rapidly entered the mainstream, at least the mainstream consciousness of groups willing to act on early information, before it is proven and tested in prospective trials. We have learned that a little bit of stress is good for the body, for example, periods of cold, periods of fasting, eating less volumes of food (even 12% less) than most, exercising daily. He does not preach extremes- a brisk cold walk after dinner will do.

Barbells: Do We Need Them?
It’s not enough to walk the dog. That is to say, there are several components to a well-executed exercise plan or prescription. For most of us, walking at 2-3 mph would best be categorized as an “activity of daily living” rather than exercise.
One reason to exercise is to improve or maintain cardiorespiratory fitness. The World Health Organization recommends a minimum of 150 minutes of moderate exercise per week, or 75 minutes of “vigorous” activity. However, the American Heart Association is now recommending 300 minutes per week, and a JAMA review article in 2015 highlighted that for longevity benefits, while 150 minutes reduced all-cause risk of death by 31%, 450-700 minutes per week resulted in a 39% decreased risk of death. If you are doing the math, that is approximately 1 hour per day. There is no question that moderate to intense cardio-aerobic exercise is a powerful longevity tool, and in fact, fitness is a better predictor of lifespan than cardiovascular risk factors and labs. The heart rate must rise to 60-70% of your heart rate maximum (something we call zone 2 training) in order to count. Read more
Merlot Meets TMAO!
This is a story that starts with some negative publicity for meat, fish, and eggs, but has a better ending, although much controversy remains and science is still working out pathways. Fortunately for us, all sides agree that wine and high-quality olive oil, as well as other high polyphenol foods, emerge as “fixers” of this newly discovered risk factor.
In 2013 there was renewed interest in the compound TMAO (trimethylamine N-oxide), which our bodies (specifically our gut bacteria and liver) make from dietary choline, carnitine, and lecithin. Those primary ingredients are enriched in meat, fish, and eggs in particular. Fish contain the highest amount of preformed TMAO of any food group. Several papers found associations between higher plasma levels of TMAO and increased risk for cardiovascular disease (heart attack or stroke) between 2013 and 2019. The papers caused a small panic in the paleo and carnivore camps, which had been advocating avoidance of grains, beans, and fruit due to the potential inflammatory effects of lectins, sugars, and processing. Also, it was difficult to square this new TMAO effect (risk) with the consistent and strong protective effects of frequent fish consumption. Other studies were published that did not always confirm the connection. The dietary ingredients (or sometimes they were given as supplements) were carnitine, choline, and lecithin. They were converted by the microbes to TMA and then by the liver to TMAO.

OURA Ring For Sleep Monitoring
Matthew Walker, PhD, is one of the leading sleep scientists in the world and currently a professor at UC Berkeley. He is the author of the book “Why We Sleep” published in 2017, and has written hundreds of papers, spoken at many professional meetings, and made several TED Talks and podcasts…all to get the word out that the right sleep is critical to our health and longevity. In fact, when asked what are the three most important ingredients for a long and healthy life, such as diet, exercise, etc., he usually responds “sleep, sleep and sleep”.
Many people “feel” that their sleep is okay…after all, if they are able to get up reasonably well in the morning, finish their day, and accomplish a few tasks after dinner, what could possibly be wrong? However, what we find when we study people’s actual time in deep sleep, time in dream sleep, and overall sleep quantity, is that as a society we are desperately “sleep deprived” and not optimized whatsoever for the best brain or cognitive outcomes over our lifespan.
