In older men, the rise and fall of saturated fats in the blood after eating yogurt closely tracks with triglyceride levels, but this link is much weaker in younger men, indicating that aging disrupts how the body manages different types of fat together.

Postprandial metabolic effects of milk and yoghurt in young and older adults
In older men, the fat from yogurt stays in the blood longer and moves up and down with triglycerides, but in younger men, this doesn’t happen — showing aging changes how the body handles fats together.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether the correlation between postprandial saturated FFAs and triglycerides strengthens with age across populations and predicts metabolic inflexibility.
A systematic review and meta-analysis of 20+ studies measuring paired postprandial kinetics of saturated FFAs and triglycerides in adults aged 20–80, calculating correlation coefficients (rm) by age group and adjusting for insulin sensitivity.
Whether aging directly alters the correlation between FFA and triglyceride kinetics by comparing young and older adults under controlled dietary challenges.
A crossover RCT with 80 healthy men aged 25–35 and 65–80, consuming 600 mL of standardized yogurt, measuring serum concentrations of 10 key FFAs and triglycerides every 30 minutes for 6 hours, and calculating within-subject correlations.
Whether individuals with stronger FFA-triglyceride correlations in middle age develop insulin resistance or cardiovascular disease over time.
A prospective cohort of 3,000 adults aged 40–60 followed for 10 years, measuring postprandial FFA-triglyceride correlations after a standardized meal and tracking incidence of metabolic syndrome and cardiovascular events.
Whether older adults show stronger correlations between postprandial saturated FFAs and triglycerides than younger adults after a single meal.
A cross-sectional study of 1,500 adults aged 20–80, measuring postprandial concentrations of seven saturated FFAs and triglycerides after 600 mL yogurt and calculating within-subject correlation coefficients by age group.
Whether individual cases of extreme FFA-triglyceride correlation correlate with advanced age and metabolic dysfunction.
A case series of 10 older adults (70+) with unusually strong FFA-triglyceride correlations after yogurt and documented insulin resistance, documenting metabolic profiles.
