The metabolic syndrome is a group of metabolic disorders, namely obesity, glucose intolerance, hypertension and hypercholesterolemia. Genetic, metabolic, and environmental factors, including diet, play an important role in the development of metabolic syndrome. several epidemiological studies have indicated that the consumption of dairy products, especially low-fat products, was inversely associated with body mass index (BMI), plasma lipids and serum cholesterol. Many dairy components such as milk minerals, proteins, or specific peptides, amino acids or milk fat may contribute to these beneficial effects. Although there is a certain focus on calcium in literature, it has not been cleared up until now which component(s) of milk and dairy products contribute to the positive effects. Additionally, many bioactive components derived from whey and some dairy fatty acids are under study for their ability to regulate adiposity and body composition. fermented dairy products and probiotic bacteria decrease absorption of cholesterol. positive effect of the consumption of dairy products on dyslipidemia needs further confirmation.
