The 2021 China Nutrition and Health Summit Forum and the kick-off meeting of "chronic disease nutrition intervention community trip" were held in Beijing recently. Participating experts pointed out that chronic diseases need comprehensive intervention, and nutrition plays an irreplaceable role in the prevention, control and treatment of chronic diseases, because nutrition is the most basic and core material for building life and maintaining health. Yin Dakui, former Vice Minister of the Ministry of health, pointed out that nutritional imbalance is a key factor in the occurrence and development of chronic diseases. With the great changes in modern lifestyle and dietary structure, serious nutritional imbalance has been caused. Only by correcting bad eating habits and bad lifestyle can we finally achieve the goal of good health and prolonging life. Wang Jianhua, executive vice president and Secretary General of China Association for the promotion of industry university research cooperation, said that nutrition is the key to solving chronic diseases and plays an irreplaceable role in the prevention, control and treatment of chronic diseases. Opening and doing a good job in the activity of "nutrition intervention for chronic diseases in community" plays an important role in improving the nutrition and health cognition level of the whole nation and curbing the occurrence and development of chronic diseases. Ma Fang, chairman of the collaborative innovation platform of China's clinical nutrition industry and professor of the Nutrition Department of Peking Union Medical College Hospital, pointed out that drugs can not bear the important task of maintaining life. Chronic diseases should follow the principle of "three points for treatment and seven points for nutrition", and "seven points for nutrition" includes scientific and reasonable nutrition matching. The etiology of chronic diseases comes from poor lifestyle, and nutrition is the first-line treatment of chronic diseases. (outlook new era)
