14 Food Research Institute in Germany, said a communique, the latest research shows that high intake of fat diet will reduce the life span, and reduce the fat intake the most help to live longer, more exercise can offset part of a large number of negative effects of fat intake.
Since the object can not be long-term human-eating test, the researchers chose to conduct experiments of two mice, one of which is the common species, the other is the type of genetic variation, the latter type of muscle tissue will consume more energy than the average , which can simulate the case of large amount of movement.
In the experiment, the researchers according to different fat, carbohydrate and protein ratio, formulated with three different diets. 11 weeks after birth in mice, researchers have begun to feed their orientation, each has been using mice with the same diet until the end of life.
The results show that the shortest life is to eat a lot of fat, adequate protein and carbohydrates, a large number of ordinary mice, they are also the highest degree of obesity, weight gain fastest category, the average life expectancy is only 548 days. The dietary intake of the same kind of genetic mutant mice with the degree of obesity and weight gain are lower speed, the average will live to about 785 days.
The oldest is a small amount of dietary fat with a large number of proteins and a large number of carbohydrates, such diets with normal mice can live 814 days on average, gene mutant mice will be close to 850 days.
Accordingly the researchers recommended that people eat less fatty food, and people who like to eat greasy food and exercise more should pay more attention. The results are published in the UK latest issue of "Aging Cell" magazine.
