Here you will find posts related to the most groundbreaking science that is available to us as it pertains to gluten intolerance and brain health. We all have the gift of brain plasticity, meaning that if we apply the conclusions of these studies to our daily lives we can actually grow new brain cells!
Alzheimer’s disease, now affecting about 5 ½ million Americans, is a disease for which we have no meaningful treatment whatsoever. That said, it certainly makes sense to look at various factors that contribute to the risk for this disease. Continue reading
There is certainly a lot of discussion these days about the ketogenic diet, especially as it relates to brain function. I thought it would be instructive to review one of the most important, and early, research studies in this area, as it reveals several very important findings that are worthy of attention.
The study, Effects of beta-hydroxybutyrate on cognition in memory-impaired adults, dates back to 2003. Why this is relevant with respect to the ketogenic diet is because beta-hydroxybutyrate is one of the ketones produced when somebody is in ketosis. The ketogenic diet is one that is aggressive in terms lowering dietary carbohydrate intake while increasing dietary fats. The production of ketones is amplified in people who supplement with things like coconut oil or MCT oil. Continue reading
Despite countless hundreds of millions of dollars dedicated to seeking out a meaningful treatment for Alzheimer’s disease, as of the time of this writing the pharmaceutical promise of dealing with this epidemic remains unfulfilled.
So, if there is no meaningful treatment, it would seem sensible to focus on how Alzheimer’s disease and other forms of dementia could be prevented in the first place.
What science has revealed over the past decade about the role our resident microbes play in keeping us healthy has truly been remarkable. It’s now clear that the more than 100 trillion microbes living on and within us are, moment to moment, playing a fundamental role in virtually every system within the human body. Who would have conceived that research would have revealed, for example, that the bacteria living within the colon are helping shape our mood, regulating our appetite, manufacturing health-sustaining vitamins, controlling our immune systems and inflammation, and even influencing the expression of our DNA?
This expanding science is compelling, humbling, and, at the same time, empowering, as we now are beginning to make real inroads into understanding how changes in the microbiome (the collection of the microbes, their genetic material, and the metabolic products they create) affect health, disease resistance and longevity.

Food allergies, and a specific skin condition called eczema, are rapidly increasing in the youth population. Now, in what may be the largest study of its kind ever performed, researchers are studying a woman’s diet during pregnancy, as well as duration of breast-feeding post-birth, to assess a child’s susceptibility to allergies, as well as risk for conditions like eczema and autoimmune disorders. British investigators, evaluating over 1.5 million people, have come up with some very compelling information.
The research is what’s called a meta-analysis, meaning that it is review of previous studies (over 400 in this case) involving over 1.5 million people, and dating as far back as 1946. The researchers discovered that there was a weak, but nonetheless demonstrable, relationship between breast-feeding and reduced risk of eczema during infancy, as well as reduced risk for type I diabetes. In addition, probiotics seemed to reduce the risk of allergic reactions to cow’s milk.
The data, however, was much more supportive of the relationship between taking a probiotic supplement while 36 – 38 weeks pregnant, and during the first 3 to 6 months of breast-feeding, and risk for childhood eczema. In fact, in those women taking probiotics, risk for eczema in their child was reduced by 22%. The scientist noted that most of the probiotics contained a bacterium called Lactobacillus rhamnosus.

I, like many of you, have often wondered about the notion of drinking a cup of coffee after the evening meal. People often say things like, “I can’t drink coffee after 4PM or I won’t be able to sleep,” and this seems to make sense. Others, like myself, can enjoy a coffee after dinner seemingly without any consequences, as far as sleep is concerned.
To help shed some light on this issue, researchers publishing in the Journal of Clinical Sleep Medicine recently reported the results of study in which individuals consumed 400mg of caffeine 0, 3, or 6 hours prior to their normal bedtime. These folks were compared to a similar group of people who received a placebo. Sleep was measured by self-reporting as well as through the use of a portable sleep monitor. Continue reading
In direct contradiction to what I learned in medical school, our genes do not directly determine every aspect of our health destiny. We now understand that subtle variations in genes, called SNPs, are highly influential in terms of health and disease. These variations in how genes function generally control various enzyme pathways in the body. Continue reading
What is metabolic syndrome? In my past videos, I’ve discussed the topic extensively. But at its core, it’s a constellation of health issues, including elevated blood pressure, lipid malfunction, carrying around extra weight, and increased blood sugar.
