Reduced meat consumption reduces the risk of type 2 diabetes
The frequent consumption of red meat significantly decreases longevity, according to a recent US study. Among other things, because this consumption is associated with a higher risk of diabetes. German researchers now report that even a temporary termination of meat could protect against type 2 diabetes.
Protection against diabetes
Diabetes is one of the most common common diseases in the country. According to health experts, about 7.6 million Germans are currently diabetic. In many cases, metabolism can be well controlled with the right nutrition. But nutrition can also help protect you from the disease. The risk of type 2 diabetes can thus already be reduced by a temporary detention from meat.
Nutrition affects diabetes risk
Earlier scientific research has shown how strong diet affects the risk of diabetes development.
19659009] Thus, American researchers found that this risk can be reduced by walnuts.
And a while ago, a study was published that found that low carbohydrate diet reduces the risk of diabetes.
On the other hand But there are also foods that increase the risk of becoming diabetic. Researchers reported for many years that the frequent consumption of red meat increases the risk of diabetes.
Avoid meat sometimes can reduce the risk.  Low food and live longer
Although many studies point to the positive effect of (interval) fasting on people who eat less, live longer and healthier.
But in addition to the intake of calorie content, the relationship between the individual diets plays an important role, the German Institute for Nutrition Potsdam-Rehbrücke (DIFE) explains in a message.
Researchers from DIfE, a partner in the German Center for Diabetes Research, have now shown in an animal model that the reduction of amino acid methionine only prevents type 2 diabetes.
The study's findings were published in the journal "FASEB Journal"
Positive health effects
Already in previous studies, the research group of DIfE's experimental diabetic unit found that mice low in protein had improved blood sugar levels and consumed more energy than animals fed standard food.
The current results show that even the reduction A single amino acid in the diet has a positive effect on health.
For example, a diet that was in methionine improved the glucose metabolism of the musk and their sensitivity to the hormone insulin.
"Interestingly, we noted the beneficial effects of low-methionics reduce the protein content and regardless of food intake and body fat," explains Dr. Thomas Laeger, project manager.
As the experts explain, methionine is a sulfur-containing, important amino acid that the body cannot produce by itself and must therefore be ingested.
Like all amino acids, it serves as a protein module. Among other things, methionine contributes to the formation of neurotransmitters and hormones and thus participates in many important bodily functions.
Although some nuts, oilseeds and vegetables also contain significant amounts of the essential amino acid, this is a plant-based diet compared to a diet of meat and vegetables. Fish that is usually low in methane.
Possible Benefits of Vegetarian or Vegan Diet
The data in the study indicate that fibroblast growth factor 21 (FGF21) allows the protective effects of the low methionite diet: when less of the amino acid is consumed, the liver releases FGF21.
Vegetarian or vegan diet usually contains small amounts of methionine compared to foods containing meat and fish.
"Together with colleagues from the Department of Molecular Toxicology and the Federal Institute for Risk Assessment, we were able to show the people who I eat vegetarian or vegan, compared to mixed dieters having elevated FGF21 levels in the blood," said first author Teresa Castaño- Martinez.
After four days of vegetarian diet, FGF21 levels in mixed diets increased
If the animal model results can be transmitted to humans, this would be an important step in the treatment of diabetes, Laeger said.
"Instead of counting on calories and generally refraining from good protein-rich foods, only the methionine content in the diet would reduce food to decrease. It may already be enough for those affected to take a vegetarian week from time to time and thereby increase their FGF21 levels. This could facilitate the acceptance of a change in diet. "However, it should be noted that some groups, including children, pregnant and breastfeeding women, have an increased need for methionine.
New knowledge of the genetic mechanisms of type 2 In-depth study of diabetes
Scientists agree that the track should definitely be sought.
It is important to find out to what extent reduced methionine intake actually contributes to increasing FGF21 levels.
Research group to carry out further studies with vegans to reveal additional evidence of possible involvement of the amino acid methionine in the development of type 2 diabetes. (Ad)
