Episode notes
Food 'Dark Matter' Matters
- Foods contain thousands of molecules beyond essential vitamins and minerals, which Beal calls 'dark matter.'
- Ultra-processed foods both add harmful contaminants and lack many beneficial natural compounds found in whole foods.
Prioritize Protein For Satiety
- Prioritize protein for most people to improve satiety and protect muscle mass.
- Aim to meet protein needs especially as you age or if you want better appetite control and muscle preservation.
Protein-Enrich Processed Foods When Needed
- Adding protein to ultra-processed products generally reduces overeating compared with fat+carb combinations.
- Favor protein-enriched versions of processed items when you need convenience.
