High-frequency dairy consumption (≥35 times/week) is inversely associated with the 10-year incidence of insulin resistance syndrome (IRS) in overweight young adults, reducing odds by 72% compared to low consumption.

If you are overweight, increasing your dairy consumption to roughly 5 times per week or more is associated with a significantly lower risk of developing insulin resistance syndrome over 10 years. This benefit was not seen in lean individuals. The type of dairy (fat content) did not change the association, suggesting that including dairy as part of a balanced diet may support metabolic health for those with excess weight.

The adjusted odds of developing IRS (2 or more components) were 72% lower (odds ratio, 0.28; 95% confidence interval, 0.14-0.58) among overweight individuals in the highest (≥35 times per week, 24/102 individuals) compared with the lowest (≤10 times per week, 85/190 individuals) category of dairy consumption.

Why this rating

Prospective longitudinal study with large sample size and rigorous adjustment for confounders, but observational design prevents causal inference.
