Episode notes
Aging Raises Protein Quality Needs Not Just Quantity
- Aging causes anabolic resistance so older adults use amino acids less efficiently and need higher essential amino acid density per calorie.
- Donald Layman warns calorie needs drop with age while protein needs stay as high or higher, stressing nutrient density.
Use Protein Supplements For Older Adults Who Can't Eat Enough
- Consider whole-protein supplements or essential amino acid supplements when older adults can't eat sufficient protein per meal.
- Donald Layman used supplementation for his parents when they struggled to consume >15 grams per meal.
Protect Muscle And Bone Through Menopause
- Maintain resistance training plus adequate protein through menopause to protect muscle and bone.
- Dr. Gabrielle Lyon recommends 1.2 to 1.6 g/kg or ~0.7–1.0 g per kg of target bodyweight and links low protein to higher hip fracture risk.
