目前认为,低蛋白饮食对人类慢性肾功能减退或动物模型的进展具有保护作用。而高蛋白的饮食则可加速肾功能的损坏。本文研究了不同年龄健康人在不限制蛋白饮食和保持低蛋白饮食两种情况下的肾功能状况。研究对象为30～80岁的非素食健康者31名(女19名,男12名)和34～80岁的素食健康者30名(女20名,男10名)。非素食组不限制蛋白摄入,每天饮食蛋白质至少100g;素食者保持素食已平均13.3年,每天摄入植物蛋白质不超过30g。记录每人身高、体重,早晨空腹测定血清肌酐和尿素氮。肌酐清除率用
It is currently believed that a low protein diet has a protective effect on the progression of human chronic renal impairment or animal models. The high-protein diet can accelerate the damage of renal function. This article examines the renal function of healthy people of both ages without limiting the protein diet and maintaining a low-protein diet. Thirty-one (19 females, 12 males) and 30 healthy vegetarians aged 34-80 years (20 females and 10 males) were included in the study. Non-vegetarian group does not limit protein intake, daily diet protein at least 100g; vegetarians have an average of 13.3 years of vegetarianism, daily intake of plant protein does not exceed 30g. Record the height and weight of each person, measure serum creatinine and urea nitrogen fasting in the morning. Creatinine clearance rate
