现在普遍流传着人体每天要饮八杯水,每杯水300ml;甚至提出每天饮水量要达到2500ml~3000ml。这么大的饮水量已经超出了人体每日饮水需求的1200ml[1],还可能超出人体的代谢能力,对健康造成损害。实验表明:过量饮水能刺激增强体内的分解代谢,蛋白质的分解可加速20%,甚至造成氮的负平衡[2]。从人体物质代谢的生化特点可知,蛋白质代谢与核酸代谢相伴而行,蛋白质需要量
It is now widely circulated that the body drinks eight glasses of water a day, 300ml for each glass of water. It even proposes that the amount of daily drinking water be 2500ml to 3000ml. Such a large amount of drinking water has exceeded the daily drinking water requirement of the human body by 1200ml [1], and may also exceed the body’s metabolic capacity and cause damage to health. Experiments show that: Excessive drinking can stimulate the body to enhance catabolism, protein decomposition can accelerate 20%, and even cause negative nitrogen balance [2]. From the biochemical characteristics of human metabolism, we can see that protein metabolism and nucleic acid metabolism go hand in hand, the protein requirement
