After eating yogurt, older men retain higher levels of seven specific saturated fats in their blood for longer than younger men, suggesting their bodies are less efficient at clearing these fats from circulation.

Postprandial metabolic effects of milk and yoghurt in young and older adults
After eating yogurt, older men keep more of seven specific fats in their blood for longer than younger men, meaning their bodies don’t clear these fats as well. The study directly measured this and found it to be true.

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 age-related impairment in clearance of specific dairy-derived saturated FFAs is reproducible across populations and predictive of metabolic inflexibility or insulin resistance.
A systematic review and meta-analysis of 15+ studies measuring postprandial kinetics of C10, C12, C14, C15, C15 iso, C14:1 c9, and C18:1 t10+t11 in adults aged 20–80 after standardized dairy intake, stratified by age and adjusted for insulin sensitivity.
Whether aging directly causes impaired clearance of these seven specific FFAs by comparing responses in young and older adults under controlled conditions.
A crossover RCT with 80 healthy men aged 25–35 and 65–80, consuming 600 mL of standardized yogurt with known FA profile, measuring serum concentrations of the seven FFAs every 30 minutes for 6 hours, with controlled diet and activity.
Whether elevated postprandial levels of these seven FFAs in middle age predict future insulin resistance or cardiovascular events.
A prospective cohort of 2,000 adults aged 40–60 followed for 12 years, measuring postprandial concentrations of the seven FFAs after yogurt and tracking incidence of metabolic syndrome, type 2 diabetes, and coronary events.
Whether older adults in a population sample have higher postprandial concentrations of these seven FFAs than younger adults after yogurt intake.
A cross-sectional study of 1,200 adults aged 20–80, measuring serum concentrations of the seven FFAs after a standardized 600 mL yogurt challenge, stratified by age group and adjusted for BMI and fasting lipids.
Whether individual cases of extreme postprandial elevation of these FFAs correlate with advanced age and normal fasting lipid profiles.
A case series of 10 older adults (70+) with normal fasting lipids but markedly elevated postprandial concentrations of the seven FFAs after yogurt, documenting metabolic and genetic profiles.
