Episode notes
Why Nutrition Research Feels Compelling
- Nutrition research excites Sarah Berry because it combines rigorous experiment design with a question everyone experiences: what we eat.
- She has run 35 randomized controlled trials and values the full research process from protocol to analysing outcomes.
Food Structure Dramatically Alters Metabolism
- Food structure (the food matrix) drastically changes how we metabolise identical nutrients.
- Whole almonds vs ground almonds showed ~30% fewer calories absorbed for whole nuts and different fullness and post-meal metabolic responses.
When To Skip Supplements And When To Use Them
- Avoid protein supplements unless you have specific needs; most people already get enough protein.
- Use B12 supplements if you're vegan/vegetarian; be cautious with artificial sweeteners and processed foods based on context.
