Thanks to the lower density of fat and energy, diets rich in fibers promote weight control, cardiovascular wellbeing and, as well known, intestine wellness.
We already know that Science shows how diets with high fiber intake benefit gut health, but scientific research also suggest that they help to maintain a healthy body weight and that they are linked to less cardiovascular disease.
An adequate fiber intake is linked to the reduction of low density lipoprotein (LDL) levels and epidemiologic studies shows that it consistently lowers the risk of cardiovascular disease and coronary heart disease. Moreover, the relationship between fiber intake and type II diabetes is suggested by many theories: it may be possible to be more successful in the prevention of diabetes by lowering glucose absorption rate, controlling weight gain, and increasing the beneficial nutrients and antioxidants load, all of which are factors relevant to the disease.
The recommended average daily nutrient intake level is about 25 g of fiber for a 2000 calorie diet. There are strong data showing a relationship between the intake of 14 g of fiber per 1000 kcals and an effect of protection against cardiovascular disease.
