Episode notes
Most People Worldwide Are Lactose Intolerant
- Lactase production declines after childhood and most humans are lactose intolerant.
- About 70–100% of East Asians and many West African populations are lactose intolerant due to genetic differences in lactase persistence.
Whole Milk Adds Calories Not More Protein
- Whole milk offers no extra protein or calcium versus skim milk; it mainly adds fat and calories.
- Both whole and nonfat milk have the same ~8 grams of protein and similar minerals; whole milk's main difference is higher saturated fat and calories.
Whole Milk Recommendation Conflicts With Saturated Fat Limits
- Prioritizing full-fat dairy conflicts with saturated fat limits in guidelines.
- Three servings of whole milk could approach most of a 2,000-calorie diet's 10% saturated fat cap, creating tension with cardiovascular guidance.
