564: Chris Kresser on Nutrient Deficiencies & Why the Way We Think About Health Needs to Change

Deficiency Stats

Chris Kresser highlights the alarming prevalence of nutrient deficiencies in the population. He notes that chronic diseases exacerbate these deficiencies by increasing nutrient demand while decreasing absorption. Kresser shares that six in ten Americans have a chronic disease, making nutrient deficiency a widespread issue 1. Katie Wells questions if it's possible to get enough nutrients from diet alone, prompting Kresser to acknowledge the growing need for supplementation 2.

   

Absorption Issues

Gut health and chronic diseases significantly impact nutrient absorption. Kresser explains that conditions like IBS and GERD hinder nutrient uptake, contributing to deficiencies 3. Inflammation and genetic factors also affect vitamin D absorption, making it crucial to understand individual differences 4. He emphasizes the importance of personalized approaches to address these challenges.

   

Modern Challenges

Modern agricultural practices and environmental toxins further complicate nutrient intake. Kresser discusses how soil degradation and increased toxin levels reduce the nutrient content in food 5. He has shifted his stance over his career, now advocating for supplementation to bridge nutrient gaps caused by these modern challenges 2.
