Episode notes
Different Dairy Foods, Different Effects
- Dairy is not a single food; milk, yogurt, and cheese have distinct matrices and effects.
- Studies should focus on individual dairy foods rather than total dairy to avoid mixed associations.
Yogurt Linked To Lower Diabetes Risk
- Multiple meta-analyses and cohort studies link higher yogurt intake to lower type 2 diabetes risk.
- The association is stronger and more consistent for yogurt than for milk or cheese.
Why Yogurt May Protect Against Diabetes
- Yogurt's fermentation and probiotic bacteria may benefit gut microbiota and cardiometabolic health.
- Yogurt also tends to be lower in sodium and can support weight control, which lowers diabetes risk.
