Vitamin B12 deficiency is much more common than statistics indicate, and it can have devastating consequences. It has been associated with everything from brain fog, cognitive decline, and heart disease to learning disabilities, infertility, and autoimmune disease. When you don’t have enough B12, it can affect virtually every system and tissue in the body. Despite this, B12 deficiency is rarely tested for—and even when it is tested, the lab results are problematic. Today I discuss the right way to get your B12 tested and how to treat it if you are deficient.

A Paleo-type diet is a great option for adults, but what about children? Will it provide everything they need to thrive? Today I discuss the specific nutritional needs of kids and how a Paleo diet can meet those needs.

Find out why I maintain that a gluten-free diet can be perfectly healthy—as long as you know what types of foods to avoid.
We’ve talked a lot on my blog about the relationship between genes and the exposome, but one thing we haven’t discussed is how they relate to aging. Today, I’ll talk to Dr. Sara Gottfried about her new book, Younger, and how specific genes or environmental factors can affect how fast your body ages. In particular, we’ll talk about how inflammation, stress, and sleep play critical roles in the aging process.
Diet is always a hot topic in the Paleo and ancestral health community. There are diehard advocates on every side. Today I talk with Robb Wolf about his new book Wired to Eat.

Why is it that both low-carb and low-fat diets can produce weight loss? Why is it so hard to avoid foods that taste good? Is it really about willpower? Today I discuss the brain’s influence on food intake with neuroscientist Dr. Stephan Guyenet. Learn why our brain is hardwired to seek out calorie-dense foods and discover four strategies for “tricking” the brain and achieving sustained weight loss.
