About
The present protocol is designed to conduct nutrigenomic and nutrigenetic studies on foods conforming to the Mediterranean diet, in order to determine the effect functional foods have on blood parameters (cholesterol metabolism, glucose metabolism, hepatic function, inflammation, nutritional status) and body composition in the context of four different diets (standard, high fat, high protein, low carbohydrate). The study focuses on the effect of these nutraceutical foods in relation to different diets. Diets were chosen to reflect the standard reference diets used by the general population, so as the outcomes of the addition of each interventional food element may be interpreted in the context of a variety of dietary patterns.
