Podcast #391: Micronutrients, Genetics, and Preventing Age-Related Diseases

When you think about diet and nutrition, you probably think about carbs, proteins, and fats. These macronutrients play a huge role in athletic performance and whether you gain or lose weight. But food is also full of micronutrients that are vital for your health and wellbeing. Unfortunately, most people overlook micronutrients, and consequently are deficient in them. My guest today has spent her career researching the ill effects of micronutrient deficiencies and what you can do to optimize them. Her name is Dr. Rhonda Patrick and she’s a biomedical scientist. Today on the show, Rhonda and I discuss micronutrients: what they are, what they do, and why we’re not getting enough of them. 

We then dig into her research into nutritional genomics, or how genes affect how your body processes nutrients. We end our conversation discussing how stressing yourself with cold exposure, heat exposure, and fasting can boost your health.
