Older men clear fat from their blood more slowly than younger men after eating dairy, regardless of whether they consume milk or yogurt, meaning aging itself reduces the body’s ability to process dietary fat efficiently.

Postprandial metabolic effects of milk and yoghurt in young and older adults
Older men took much longer to clear fat from their blood after drinking milk or eating yogurt than younger men, no matter which dairy product they ate — showing that getting older makes it harder for the body to process fat.

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 postprandial triglyceride clearance is a consistent phenomenon across populations and whether it predicts long-term cardiovascular events.
A systematic review and meta-analysis of 20+ RCTs and cohort studies measuring postprandial triglyceride iAUC and iTmax in adults aged 20–80 after standardized high-fat meals, stratified by decade of age and adjusted for BMI and insulin sensitivity.
Whether aging directly causes slower triglyceride clearance by comparing responses in young and older adults under identical dietary challenges.
A crossover RCT with 100 healthy men and women aged 25–35 and 65–80, consuming 600 mL of standardized high-fat dairy on two occasions, measuring triglyceride kinetics every 30 minutes for 6 hours, with controlled activity and fasting.
Whether individuals with higher postprandial triglyceride responses in middle age are more likely to develop atherosclerosis or metabolic syndrome over 15 years.
A prospective cohort of 3,000 adults aged 40–55 followed for 15 years, measuring postprandial triglyceride iAUC after a standardized meal and tracking incidence of cardiovascular disease, diabetes, and fatty liver disease.
Whether older adults in a population sample show higher average postprandial triglyceride levels than younger adults after a single meal.
A cross-sectional study of 1,500 adults aged 20–80, measuring postprandial triglyceride response after a standardized 600 mL dairy challenge, stratified by age group and adjusted for BMI and fasting lipids.
Whether individual cases of extreme postprandial triglyceride elevation correlate with advanced age and normal fasting lipids.
A case series of 10 older adults (70+) with normal fasting triglycerides but unusually high postprandial responses after dairy, documenting metabolic profiles and lifestyle factors.
