Is Organic Worth It? Organic vs Conventional Farming & Its Role In Human Health – Dr. Andrew Smith

Understanding Organic Agriculture: Soil, Nutrition, and Human Health with Dr. Andrew Smith. This episode dives into the history, science, and future of organic farming, emphasizing its role in soil health, nutrition, and climate impacts. Dr. Andrew Smith shares insights from decades of research at the Rodale Institute and explores how organic practices can nourish both the planet and human health.

Main Topics:

* The founding and mission of the Rodale Institute and origins of organic farming.
* How soil health directly impacts food quality and human health, including long-term soil and crop trials.
* The decline in nutrient density in conventional crops.
* Organic vs conventional farming practices, including the use of pesticides and tillage.
* The importance of regenerative organic practices and their potential to sustain global food needs.
* The role of microbiology, soil microbes, and phytochemicals in enhancing nutrient profiles and health benefits.
