Relationship between nutrition and diseases:

Effect of nutrition on immune function. Malnutrition affects immune function from cellular immunity, humoral immunity and other aspects, thus affecting diseases. Thymus is the place where bone marrow stem cells are induced to become T cells, and thymosin secreted by thymus can promote lymphocytes to produce immunocompetent lymphocytes.

It has been proved that the thymus of malnourished children is atrophied, and its weight is reduced by about half, and pathological changes have taken place in the thymus tissue, such as lobular atrophy, unclear boundary between skin and marrow, and cytopenia.

Effects of nutrition on atherosclerosis, hyperlipidemia, obesity, etc. Epidemiological surveys and nutrition surveys all over the world show that dietary fat intake is obviously positively correlated with the incidence and mortality of atherosclerosis, hyperlipidemia, hypercholesterolemia and coronary heart disease, etc. The correlation coefficient of the survey results in 2 countries is .489 ~ .654.

Especially, saturated fatty acids in dietary fat have a more significant effect, 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.
