Brief summary
The aim of the study is to evaluate the synergistic effects of daily consumption of food products fortified with bioactive components (fibres, polyphenols, omega-3, Slow Digestible Starch) for 9 weeks, compared to the daily intake of standard food products on low-grade inflammation in cardiometabolic risk subject. The inflammatory parameters will be assessed in fasting and in postprandial period after the consumption of a hyper-carbohydrate and hyper-lipidic test meal called Flexmeal. A metabolic stress will be induced by a fructose ingestion challenge during the last 6 days of interventional period.
Interventions
OTHERbioactive components fortified food products intake (biscuits and cookies)
Volunteers will have to consume daily 100 g of fortified biscuits and cookies instead of those usually consumed during nine weeks. The last week, volunteers will have to consume daily a fructose solution (3g/kg fat free mass)
OTHERcontrol food products intake (biscuits and cookies)
Volunteers will have to consume daily 100 g of standard biscuits and cookies instead of those usually consumed during nine weeks. The last week, volunteers will have to consume daily a fructose solution (3g/kg fat free mass)
