Healthy Effects of Milk and Dairy Product Consumption in the Mediterranean Area and Japan

Abstract

Milk is a food enriched in essential components for human health. Especially, in the Mediterranean area, besides cow's milk, milk from goats, sheep, and donkeys, is largely used. The consumption of animal milk is an important component of the Mediterranean (MED) diet, even if in moderate amounts. Milk is a complete food since it contains proteins, carbohydrates, and fats, as well as micronutrients (minerals and vitamins). Milk-fermented products are largely consumed in the MED diet, such as cheese and yogurt, which are rich in essential metabolites, bioactive compounds, vitamins, minerals, and exopolysaccharides. A large body of evidence suggests that consumption of milk and dairy products does not increase the risk of all-cause mortality, type 2 diabetes, and cardiovascular disease, even if some earlier studies have reported harmful effects associated with their higher consumption. Also, in Japan, despite the lower consumption of milk than in Western countries, intake of bovine milk is associated with healthy effects. The present review describes the effects of the various constituents of animal milk on human health, with special reference to the Mediterranean area and Japan. Experimental data and clinical trials support the ability of milk and dairy products to lower the risk of chronic diseases.
