Effects of Fermentation and Age on Postprandial Metabolic Responses to Milk and Yoghurt: A Randomised Crossover Trial

Postprandial metabolism plays a key role in maintaining cardiometabolic health, and its impairment with ageing is associated with increased disease risk. While yoghurt consumption has been linked to improved fasting metabolic markers, its acute postprandial effects remain poorly understood, particularly in older adults. This study investigated whether dairy fermentation and age influence postprandial metabolic responses and whether fermentation may attenuate age-related metabolic postprandial dysregulation.
