人类寿命的延长受很多因素影响,其中饮食营养是长寿的物质基础.老年人因腺体分泌机能减弱,新陈代谢过程缓慢,所以过量摄取食物可造成肥胖,而肥胖又可带来许多老年性疾病,从而使寿命缩短.国外学者研究指出,超过标准体重5～14%的老年人,其死亡率可增加22%,超标准体重13～25%时,死亡率增加44%,超25%时,死亡率增加74%.老年人体重低于标准体重的15%是较为理想的,这是死亡率最低的体重.那么,根据老年人的生理特点,食物六大营养素
Longevity of human life is affected by many factors, of which diet and nutrition is the material basis of longevity.The elderly due to weakening secretion function of the gland, the slow metabolic process, so over-intake of food can cause obesity, and obesity can cause many elderly diseases, So that the life expectancy shortened.Researchers from foreign countries pointed out that more than 5 to 14% of the standard weight of the elderly can increase the mortality rate of 22%, 13 to 25% exceed the standard weight, the mortality rate increased 44%, 25% over death The rate increased by 74% .An elderly weighing less than 15% of the standard weight is more ideal, this is the lowest mortality body weight.So, according to the physiological characteristics of the elderly, the six food nutrients
