Evaluation of a Dietary Supplementation Combining Proteins and Pomegranate Extracts in Older People

The aim of the Delicen's project is to find an effective solution to avoid undernutrition in the elderly by proposing an assortment of food products for people who are undernourished or at risk of undernutrition. These products will be enriched with proteins and pomegranate extracts. Before to realize the impact study to test products enriched with proteins and pomegranate extracts, a safety study will be carried out.

The objective of this safety study (double-blind randomized clinical trial) is to evaluate the safety of a combination of proteins and pomegranate extracts in healthy subjects aged 65 years or more in comparing a control group consuming 20g of proteins (100% of lactoserum proteins) and 650mg of maltodextrin to a test group consuming 20g of proteins (100% of lactoserum proteins) and 650mg of pomegranate extracts after 21 days of supplementation.
