Is a fat diet healthy?
Doctors found out now that if people between the ages of 20 and 40 years of a high-fat diet, this increases your risk for many different diseases later in life significantly.
The scientists from the Qingdao University in China noted in its recent study that a fat-rich diet in early life increase the risk for various diseases later in life. The experts published the results of their study in the English journal “Good”.
Unhealthy diet, changes the micro-biome
Fat-rich foods can reduce healthy bacteria in the gut and even to mutate, say the experts. In Particular, an unhealthy diet changes the micro-biome, which reduce the ingested food in the stomach. As a result, the markers of Inflammation increase in the whole body. The published data suggest that long-term metabolic disorders such as Diabetes, heart disease, and stroke can occur.
Study had 217 volunteers
For the study, the Chinese physicians examined 217 healthy 18-to 35-year-old subjects. The researchers wanted to find out whether different amounts of food the gut bacteria fat change in healthy young adults. The scientists divided the subjects into three different groups. The Participants were then given a diet with different ratios of carbohydrates (white rice and wheat) and oils (mainly soybean oil). The fiber and protein intake was maintained in all subjects.
How did the subjects?
The three final forms of the diet of the groups included a low-fat diet, with lipids 20 percent of the energy intake of the Participants accounted for. The second group received a diet with a moderate fat content, with 30 percent of the energy intake from lipids covered. The third group received a diet with a high fat content, with lipids, 40 percent of energy consumption accounted for. All the Participants had to hold for a period of six months to the selected Form of diet.
Low-fat diet resulted in the highest weight-loss
The influence on the intestinal bacteria and the inflammatory markers was established on the basis of Blut– and chair be determined from samples taken at the beginning and at the end of the study. After six months, Participants had decreased in all three groups of weight, with those acceptances, with a low-fat diet the most weight. Some of the other changes with potential impact on the long-term health, however, were only in the samples from the group with a high fat content visible.
What was the impact of the diet on the intestinal bacteria?
Although it had not changed, the total volume of the intestinal bacteria in the three groups significantly increased the number of beneficial bacteria that produce short-chain fatty acids, including butyrate, only in the group with a low-fat diet. In contrast, the number of these beneficial bacteria in the group was reduced with the high content of fat in their diet. In addition, had increased in this Form of diet, the number of unhealthy bacteria, which were found, for example, in the intestines of people with type 2 Diabetes. So-called Blautia bacteria, which are associated with lower Cholesterol levels, were observed in high quantities in humans, which is held to a low fat diet. Bacteria of the genus Bacteroides, which are associated with an increased level of cholesterol, occurred more frequently in subjects with a high-fat diet. In addition to the high fat diet was associated with significant and potentially harmful changes in the metabolism of fatty acid. This has led to an increased concentration of substances, one of which is believed to trigger inflammation. In the case of a low-fat diet is exactly the opposite could have been observed.
There were limitations in the study?
Unfortunately, samples were taken only at the beginning and at the end of the study. By a more frequent collection of samples a more complete picture of microbial changes would have resulted. Since all three groups decreased weight, is also not entirely clear whether the weight loss triggered the observed changes, or Vice versa. The results seem to illustrate the necessity of a reduction of dietary fat, experts say. Compared with a low-fat diet of the long-term consumption of a diet rich in fat does not seem to be useful. The results could be for industrial countries is relevant, in which the fat intake is usually very high. (as)
