British media: studies say that low calorie diet can delay senility.
British media said a study of people reducing calorie intake found the most powerful evidence to date. This calorie restriction can slow people's metabolism, which makes people expect low calorie lifestyles - or mimics of restricted biological effects - can prolong the health of older people and even prolong life.
according to the British nature weekly web site in March 22nd, studies of worms, flies and mice have shown that caloric restriction reduces the metabolic rate and prolongs life. However, experiments on humans and other primates with longer life span are more difficult to carry out, and no definite conclusion has yet been reached. The study was part of a multicentre trial of the so-called "long-term impact assessment of total energy intake" (CALERIE), sponsored by the National Institutes of health. These randomized controlled trials tested the effects of caloric restriction on metabolism in more than 200 healthy and non obese adults over two years.
Rosalyn Anderson, who studies aging at the University of Wisconsin at Madison, led two major independent studies on the limit of calorie intake in Ganges RIver, she said: "the CALERIE test plays an important role in solving the question of whether the speed of human aging can change. The new report provides the most powerful evidence so far that all the knowledge we have learned in other animals can be applied to ourselves. "
reported that the latest research report was published on the 22 website of the American Journal of cell metabolism. The study analyzed data from 53 CALERIE participants recruited from the Peng Ningdun biomedical research center in Baton Rouge, Louisiana. About 4 of the world's 20 most advanced metabolic rooms are located at the research center, which resemble small sealed hotel rooms to measure the amount of oxygen inhaled by participants and the amount of carbon dioxide discharged by participants in minutes. Anderson said that this enables researchers to track the process of energy utilization in metabolic room participants with unprecedented accuracy. The ratio between the two gases and the analysis of nitrogen in the urine of the participants indicate whether the user is burning fat, carbohydrates or protein.
reported that participants aged between 21 and 50 years old. They were randomly divided into two groups: 34 in the trial group, 15% on average, and 19 in the control group. At the end of the year, all participants received a series of metabolic and biomarker tests related to aging, including damage caused by oxygen free radicals released in the metabolism.
