[Current trends in nutrigenomics of obesity].

One of the most general chronic illness in the world is obesity, which lead to progression of cardiovascular diseases, diabetes mellitus type 2, metabolic syndrome and other diseases. Slow body weight gain, that leads to overweight, is a long-term aftereffect of a long-term positive energy balance, which occurs as a result of physical activity reduction and calorie intake increasing. Trend in the reduction of physical activity and increasing the caloric value of food intake is probably the main reason of increasing patients with obesity, but it's necessary to mention that this tendency occurs because of genetic variation in population.
