爱尔兰论文代写被发现:动物卡路里限制

卡路里限制是指从正常饮食中摄入的热量减少30%。在1930年,研究人员发现,老鼠和老鼠在喂食30%低卡路里的食物时可以活得更久。因此,研究人员发现,卡路里限制可能会增加诸如苍蝇、蠕虫、酵母、老鼠等动物的寿命。调查人员还对非人类灵长类动物(与人类有密切关系的动物)的热量限制进行了测试。限制热量的饮食是给猴子的,这表明它们与正常食用者相比,与年龄有关的疾病少了三倍(Ardies, 2014)。与正常喂养的猴子相比,被测猴子的寿命增加了。

然而,也发现所有动物的卡路里限制并不会延长它们的寿命。一些喂食热量限制饮食的老鼠寿命短于平均寿命。寿命变短的主要原因是野生鼠的遗传差异。从现在开始,人们说基因在寿命中起着重要的作用。科学家正在研究热量限制可以增加人类的寿命,并对健康有积极的影响。研究表明,降低胆固醇、空腹血糖、体重、脂肪和体温会增加寿命。它将增加线粒体的功能,降低细胞水平的DNA损伤。

Calorie restriction is referred to as the 30% decrease in the consumption of calorie from the normal diet. In the year 1930, the investigators found that mice and rats can live 40% longer when they are fed diet having 30% low calorie. Thus, the investigators observed that calorie restrictions could increase the lifespan of animals such as flies, worms, yeast, mice, etc. The investigators also tested calorie restriction in the non-human primates (animals closely related to human beings). The calorie-restricted diet was given to monkeys which show that they had three times less disease related to age in comparison to normal eaters (Ardies, 2014). The life span of the tested monkeys increased in comparison to normal fed monkeys.

However, it has also been found that calorie restriction in all animals does not increase their lifespan. Some of the mice fed calorie-restricted diet lived shorter that their average lives. The main reason of living shorter is genetic differences in the wild mice. Henceforth, it has been said that genetics play a significant role in the life span. The scientist is investigating on calorie restrictions can increase the life span of humans and have a positive effect on the health. It has been investigated that lowering cholesterol, fasting glucose, body weight, fat and body temperature will increase the life span. It will increase the functioning of mitochondria and decrease DNA damage at cellular level.
