title: [Dietary survey and biochemical study of blood and urine among Yi and Han nationality farmers in low prevalent district of hypertension].
abstract: This paper reports the dietary investigation (55 persons) and nutrient biochemical analysis of blood and urine (173 persons) among Yi and Han nationality farmers with low incidence of hypertension in Weinin, Guizhou. The results suggest that the three main nutrients as protein, fat and carbohydrate had no uniform relationship to the blood pressure, but high potassium and low sodium diet was intimately correlated to the low incidence of hypertension. The Na/K ratio of dietary intake and urine was more closely related to blood pressure. The relationship between calcium and blood pressure was quite complicated. The appropriate ratio of calcium and magnesium intake may be significant in the prevention and treatment of hypertension. It also indicates some intrinsic connection between lipid metabolism and blood pressure, while the degree of smoking is definitely correlated to blood pressure.
