[The importance of nuts in the prevention of various diseases].

Nuts are rich in unsaturated fatty acids, protein, dietary fiber, a number of micronutrients and biologically active substances. The aim of this review is to summarize and analyze current data on the role of nuts in human nutrition. Results. Large prospective cohort studies show an association between regular consumption of nuts (>= 140 g per week) and a reduced risk of coronary heart disease. In randomized controlled trials, strong evidence has been obtained that consuming nuts lowers blood cholesterol and improves glycemic control in patients with type 2 diabetes. Recent epidemiological studies show that high nut consumption does not increase body weight; rather, the inclusion of nuts in the hypocaloric diet can help to control or reduce body weight and waist circumference. A meta-analysis of prospective cohort studies shows that nut consumption is associated with a reduced risk of death from all causes and from chronic diseases. "Nut snack" is a good strategy to avoid weight gain and improve chemical composition of the diet. Conclusion. Adequate replacement of some foods in the diet with nuts does not cause body weight increase and helps to prevent a number of diseases.
