KEYNOTE | What is the Role of Ultra-Processed, Plant-Based Products in the Diet?

Excess consumption of ultra-processed foods is linked to increased risks of disease and death. However, these associations appear to be driven largely by sweetened beverages and processed meats. In that case, instead of being a part of the problem, plant-based meats may be the solution to the ultra-processed foods issue. Unlike other ultra-processed foods, plant-based meats are healthier than the foods they were designed to replace, but how do they compare to whole plant foods? Dr. Greger will explore how important is it to shift from just minimizing animal products to also minimizing the intake of processed foods.

How Not to Age

The term “anti-aging” should be reserved for interventions that target one or more of the established aging mechanisms. Nonpharmacological means to target these hallmarks of aging will be discussed and the common denominators of the diets and lifestyles of healthy, long-lived populations will be teased out. Dietary approaches will be explored to preserve our bladder, brain, and bowel function as we age. Methods to preserve muscle mass as well as tips to combat skin aging and the vasomotor symptoms of menopause will also be explored.
