Did you know that many traditional hunter-gatherer societies ate as many as 100 different species of plants? For several years, I’ve known that the biggest difference between my diet and the ancestral diet was not the meat that I was eating, or the eggs, or even the nuts and seeds, but that it was the vegetables—specifically, the lack of diversity in the plant foods I was eating. This lack of diversity not only affects our phytonutrient intake, but it also affects our microbiome because different types of gut microbes prefer different types of nutrients. Today I’m talking with Dr. Thomas Cowan about his unique solution to adding more plant phytonutrients to every meal.
We have a simple question this week, but I’m sure it’s one that a lot of people actually wonder about. We all hear that we should eat a lot of vegetables, but is this one of these assumptions that we just don’t question and it’s actually not true? What does the research actually say about how many servings of vegetables a day we should eat? What are all the relevant issues? There are, of course, lots… Read More
Over the last couple of weeks we’ve been discussing the benefits and risks of low-carb and very low-carb diets. Laura, one of my staff nutritionists, kicked things off with an article called “Is a Low-Carb Diet Ruining Your Health?”, and I followed up with an article called “7 Things Everyone Should Know About Low-Carb Diets”. Then Kelsey, my other staff nutritionist, wrote an article called “The 3-Step Process for Determining Your Ideal Carbohydrate Intake”. In… Read More
Many of you have probably heard of the ‘alkaline diet’. There are a few different versions of the acid-alkaline theory circulating the internet, but the basic claim is that the foods we eat leave behind an ‘ash’ after they are metabolized, and this ash can be acid or alkaline (alkaline meaning more basic on the pH scale). According to the theory, it is in our best interest to make sure we eat more alkaline foods… Read More
A recent study shows that fruits and veggies don’t lower the risk of heart disease – unless they’re eaten with fat!
