The abundance of fibers gives the Variegated Radicchio di Castelfranco many beneficial properties for the body. Associated with the right amount of water, they increase the sense of satiety by increasing the volume of the meal in the stomach - a very useful feature in the slimming diet. Especially the soluble ones, they create a gel that modulates nutritional absorption through two mechanisms: they reduce the absorption speed of carbohydrates, by decreasing the insulin glycemic index of the meal, hinder the absorption and reabsorption of fats, especially cholesterol and bile juices - rich in endogenous cholesterol.

The high concentration of molecules endowed with this function makes this vegetable suitable to fight the oxidative stress of the organism, acting preventively against the tumor evolution and hindering the onset of metabolic pathologies.
The richness of water and potassium is considered a preventive aspect of primary arterial hypertension, especially sodium-sensitive - potassium acts metabolically in contrast to sodium and water increases diuresis, favoring the elimination of the unwanted ion. In addition, these are two nutritional factors largely eliminated with sweat, greater in hot climates and in sports practice. Potassium and magnesium are alkalizing minerals which, when deficient in the body, can cause muscle cramps. The nutritional action of the iron and calcium contained in the variegated Radicchio di Castelfranco is marginal.
