Effect of nutrition on immune function Malnutrition affects the immune function of human body from cellular immunity and humoral immunity, thus affecting diseases. Thymus is the place where bone marrow stem cells are induced to become T cells. Thymosin secreted by thymus can promote lymphocytes to produce immunocompetent lymphocytes.
Studies have proved that the thymus of malnourished children is atrophied, the weight is reduced by about half, and the thymus tissue is diseased, such as lobular atrophy, unclear boundary between skin and bone marrow, and cytopenia.
Effects of nutrition on atherosclerosis, hyperlipidemia and obesity. Epidemiological and nutritional surveys around the world show that dietary fat intake is positively correlated with the morbidity and mortality of atherosclerosis, hyperlipidemia, hypercholesterolemia and coronary heart disease. The survey results of 20 countries show that the correlation coefficient is 0.489 ~ 0.654.
Especially, the saturated fatty acids in dietary fat play a more significant role, such as myristic acid and palmitic acid can increase blood cholesterol and stearic acid, and 12 carbon medium-chain fatty acids can increase blood lipids.
Extended data
The incidence of chronic diseases in China has risen rapidly, with 260 million confirmed patients, accounting for 85% of the total deaths and 70% of the total disease burden. This is a major public health problem, which highlights the importance of perfecting the national chronic disease prevention and control service network and establishing a chronic disease monitoring and information management system.
In order to achieve the goal of prevention and control of chronic diseases in China and ensure the smooth progress of national health promotion, under the guidance of the Propaganda Department of the National Health and Family Planning Commission, the 6th China Chronic Disease Management Conference was held in Beijing International Convention Center on June 8th-10, with the theme of "New Planning, New Practice and New Technology Helping Chronic Disease Management".
