The population of Japan and Okinawa is known for the longest life expectancy, which many researchers rightly associate with the nature of nutrition existing in these territories. The Japanese diet and Okinawan diet, along with other traditional diets, are real examples of historically established sustainable patterns of healthy eating. Asian eating styles have marked differences from European eating patterns, not only in differences in food sources, but also in eating habits. The article presents the historical, climatic and cultural features of these diets; the issues of food composition, energy and nutritional value of these models of nutrition are considered in detail with an analysis of the differences existing between them; highlights the benefits of products grown mainly in Japan, which are ration-forming for the population of this country; as well as the results of scientific studies on the protective effect of the Japanese and Okinawan diets on human health and disease prevention.

The changing structure of food consumption requires updating the nutrition assessment tool, taking into account modern dietary patterns.Aim. To develop, evaluate the validity and reproducibility of semiquantitative food frequency questionnaire (FFQ) for the adult population.Material and methods. The FFQ questionnaire was developed as part of the Russian part of the international Prospective Urban and Rural Epidemiological (PURE) study. To compare the quantitative parameters of the energy and nutritional value of diet, the validation used data on the actual nutrition of 294 men and women aged 25-65 years, collected by 2 methods: 24-hour dietary recall (24hDR) — 4 surveys per year (1 time per season) and the developed FFQ — 2 surveys: initially (FFQ1) and after 12 months (FFQ2).Results. The minimum mean values for the vast majority of nutrients were recorded by the 24hDR method, while higher values — by FFQ2, and maximum values — by FFQ1. Pearson’s correlation coefficients ranged from 0,19 (retinol equivalent) to 0,53 (cholesterol), showing a moderate relationship between the two methods. After crossclassification, the proportion of subjects assigned to the same quartile of 24hDR and FFQ2 nutrient profile ranged from 26,9% (β-carotene) to 43,5% (cholesterol), and those assigned to opposite quartiles ranged from 3,1% (cholesterol) to 11,2% (retinol equivalent), indicating good agreement between these methods. The Bland-Altman plots showed slightly overestimated FFQ2 scores for total carbohydrate, protein, and dietary calories. The Pearson correlation between FFQ1 and FFQ2 values ranged from 0,46 to 0,82. The intraclass correlation showed the questionnaire reproducibility coefficients lower than the Pearson correlation. However, most of them remained at a value of >0,60.Conclusion. The results showed predominantly moderate validity and good reproducibility of the modern FFQ version, which allows it to be used to assess nutrition in the adult population with estimation of the energy and nutritional value of diet in the protocols of Russian epidemiological, preventive and clinical studies.

В настоящее время в мире наблюдается активная популяризация растительных рационов, одновременно в публикациях прослеживается и научная дискуссия по данному вопросу. Результаты исследований и накопленная доказательная база позволяют провести аналитический обзор преимуществ и ограничений вегетарианских типов питания. В статье подробно рассмотрены разные варианты ограничительных стилей питания с позиции как «здоровья человека», так и «здоровья планеты». Обсуждаются вопросы энергетической и пищевой ценности растительных рационов, их сбалансированности, соответствия критериям рациона здорового питания и безопасности в аспекте обеспеченности организма необходимыми веществами. Представлены данные международных и российских исследований о связи вегетарианских диет с факторами риска развития хронических неинфекционных заболеваний, сердечно-сосудистых и онкологических заболеваний, а также с уровнем смертности. Приведены рекомендации ведущих экспертов.

The methodological guidelines are developed as a practical document for medical specialists working in the field of preventive medicine, in order to expand and improve the provision of this type of medical service to the adult population. The methodological guidelines include an informational and informative part for medical specialists and a practical part for patients, presented in the format of memos, contain the main sections-healthy nutrition, correction of eating habits, issues of modifying the diet for the main alimentary-dependent risk factors for chronic non-communicable diseases, such as arterial hypertension, obesity, disorders of lipid, carbohydrate and purine metabolism, a decrease in bone mineral density. They are intended for medical specialists working in the field of prevention, for doctors and secondary medical personnel of offices and departments of medical prevention, public health and medical prevention centers, healthy lifestyle specialists, teachers of medical educational institutions, for specialists who develop and implement educational programs for patients, as well as for medical specialists of a therapeutic profile.

Nutrition is one of the most significant factors influencing the state of health, the development of diseases and the generally the human longevity. The nature of nutrition, which has a protective effect, is the basis of the healthy diet. Among healthy nutritious rations, there are those that have developed naturally, formed from the cultural food heritage and later were made in scientific nutritional recommendations. These are such diets as the Mediterranean type of food, the Scandinavian diet, the Tibetan style of food, etc. At the same time, there are diets specially developed by specialists for specific purposes. All of them correspond to the basic principles of the healthy diet: balance, usefulness and energy balance. This article offers an overview of the use of individual diets that have been developed by nutritionists, such as the intermittent fasting diet, the Paleo diet, and the DASH (Dietary Approaches to Stop Hypertension) diet. The article discusses the differences and advantages of these dietary approaches, presents the results of effectiveness, considers the limitations and features of their use.

In modern conditions, the role of active interaction between medical professionals and patients in improving health, reducing the risk of diseases, increasing adherence to a healthy lifestyle, the formation of a responsible attitude to health. The best approach is early comprehensive prevention, aimed at preventing the development of risk factors for major chronic noncommunicable diseases, especially from a young age, at a time when behavioral stereotypes, habits and skills are formed and consolidated. It is proved that the unhealthy diet is a risk factor for the development of chronic non-infectious diseases. Counseling patients on nutrition includes an assessment of the individual nature of nutrition, associated alimentary-dependent risk factors for the development of personalized recommendations. This article proposes a variant of consulting young people with the algorithm of assessment and analysis of eating habits of the patient in accordance with the principles of healthy eating.

In total 256 patients with arterial hypertension were examined in one of the districts of out-patients clinic. Preventive clinical investigation revealed high frequency of nutrition disorders, overweight, obesity and hypercholesterolemia. On the base of these results necessary size and character of dieteologic intervention were evaluated. 90.2% patients with arterial hypertension need overweight and obesity correction, 90.3%--correction of hypercholesterolemia. It was determined that by majority patients recommendations must be aimed to decrease of fat consumption, cholesterol, simple carbohydrates, salt and vegetables and fruits.
