[Cardiovascular nutrition: disease management and prevention as major public health problem nowadays]

Cardiovascular disease (CVD) is the leading cause of death in many developed countries. At the same time, nutrition is the basis of preventive cardiology. Earlier researches were focused on the importance of individual nutrients, including saturated fats, sodium, and dietary fiber, or certain foods, such as fruits, vegetables, fish, and olive oil, in the development of СVD. Recently, however, an analysis of nutritional patterns has been preferred to take into account the heterogeneity of the diet and the interaction of foods and nutrients. Besides, studies of the cardioprotective potential of bioactive compounds, e.g. polyphenols, peptides, oligosaccharides, vitamins, mono- and polyunsaturated fatty acids, are of particular interest. This paper covers dietary patterns that are associated with improved cardiovascular outcomes, including the Mediterranean diet. The use of a pattern-based approach will help practitioners make optimal and meaningful changes to the patients' diet. Personalized diet therapy is also very important, which implies flexibility and tailoring guidelines to patient needs and comorbidities.
