Metabolic Signatures of Dairy Products Ingestion in Humans: Effect of Age

Despite the fact that dairy products are greatly consumed, it remains today very difficult to determine with a classical blood biochemical test whether a person has ingested a fresh fermented dairy product or just milk, while their biological, metabolic and health impacts may be different. The metabolic footprint left by the consumption of these products could be modified by the age of the consumer. Indeed, in the elderly, the processes of digestion, assimilation and metabolism are known to be altered /different compared to healthy adults. Thus, different metabolic signatures in the elderly could appear as the result of a less effective use and metabolism of the nutrients ingested. This could further also result in different or altered biological effects on dairy products.
