我们中国居民的日常饮食中,碳水化合物是膳食结构中能量的主要物质来源,供能比高达61%。碳水化合物在人体内消化后,主要以葡萄糖的形式被吸收利用,然后以糖原的形式储存在肝脏与肌肉中,当机体摄入过多碳水化合物时,多余的碳水化合物便会转化为脂肪。由于脂肪一般不能直接转变成葡萄糖,因此当碳水化合物摄入不足时,主要是动用体内蛋白质分解代谢提供能量。低碳水化合物饮食,又称高蛋白质饮食,是通过每
In the daily diet of our Chinese inhabitants, carbohydrates are the main source of energy for the dietary structure, providing energy for up to 61%. Carbohydrates in the human body after digestion, mainly in the form of glucose absorption and utilization, and then stored in the form of glycogen in the liver and muscle, when the body intake of excess carbohydrates, excess carbohydrates will be converted to fat. Since fat generally can not be directly converted to glucose, when carbohydrate intake is insufficient, it is mainly used to provide energy for protein catabolism in the body. Low-carbohydrate diets, also known as high-protein diets, are made through each
