Reducing meat consumption reduces the risk of type 2 diabetes. T
According to recent US study, frequent consumption of red meat significantly reduces the expected life expectancy. Among other things, because this consumption is associated with a higher risk of diabetes. German researchers now report that even occasional abstinence of meat could protect against Type 2 diabetes.

Protect against diabetes
Diabetes is one of the major common diseases in this country. According to health specialists, about 7.6 million Germans are currently diabetic. In many cases, metabolic disease can be well controlled by proper nutrition. However, nutrition can also make an important contribution to protecting yourself from illness. Therefore, the risk of type 2 diabetes may already be reduced by occasional abstinence of meat.
Diet affects the risk of diabetes
Previous scientific studies have shown how much nutrition affects the risk of developing diabetes.
For example, American researchers have found that nutrition can reduce that risk.
A recent study has shown that low carbohydrate lowers reduce the risk of diabetes.
On the other hand, there are foods that increase the risk of diabetes. Scientists have reported many years ago that frequent red meat consumption increases the risk of diabetes.
Occasional restraint of meat could suppress this danger.
Eat less and live longer
Although numerous studies of the positive effects (intervals) of starvation point to the fact that people who eat less, live longer and healthier.
But apart from reduced calorie intake, the ratio of individual food ingredients also plays an important role, explains the German Potsdam-Rehbrücke Diet Institute (DIfE) in a statement.
Researchers from DIfE, a partner of the German Diabetes Research Center, have now shown in the animal model that only a reduction of methionine amino acids prevents Type 2 diabetes.
The results of the research were published in the journal "FASEB Journal".
Positive impact on health
In previous studies, the research team at the DIfE Experimental Unit for Diabetes has found that mice receiving a low-protein diet improved blood glucose levels and consumed more energy than animals feeding standard foods.
Current results now show that even reducing an amino acid in food has a positive effect on health.
Thus, nutrition poor in methionine has improved the metabolism of sugar in mice and their sensitivity to insulin hormone.
"It is interesting that we have observed the beneficial effects of low-methionine diet without reducing the protein level and regardless of the intake of food and body fat," explains Dr. Sc. Thomas Laeger, project manager.
As experts explain, methionine is a vital amino acid that contains sulfur and which the body can not produce alone and should therefore be fed with food.
Like all amino acids, it serves as a building block protein. Among others, methionine contributes to the creation of neurotransmitter and hormone and is therefore included in many important body functions.
Although certain nuts, oilseeds and vegetables contain significant amounts of essential amino acids, plant nutrition is usually low in methionine compared with meat and fish meals.
Possible benefits of vegetarian or vegan diet
Data in the study indicate that fibroblast growth factor 21 (FGF21) mediates in the protective effects of a low-methionine child: when smaller amino acids are consumed, the liver releases more FGF21.
Vegetarian or vegan diets usually contain small amounts of methionine in comparison to food containing meat and fish.
"Together with colleagues from the Department of Molecular Toxicology and the Federal Bureau of Risk Assessment, we have been able to show that people who eat vegetarian or vegan foods have elevated FGF21 blood levels compared to mixed diets," says Teresa Castaño-Martinez, the first author.
After just four days of vegetarian diet, FGF21 levels also increased in the blood of mixed diets.
"If the animal model results can be transmitted to humans, this would be an important step in the treatment of diabetes," says Laeger.
"Instead of counting calories and generally maintaining protein-rich delicious foods, only the content of methionine in the diet should be reduced." It may already be enough for those who have been affected to take a vegetarian week and thus increase their FGF21 levels. This could greatly facilitate the acceptance of change in diet. "
It should be noted, however, that certain groups, such as children, pregnant women and breastfeeding, have an increased need for methionine.
Improve new knowledge about type 2 diabetes mechanisms
Scientists agree that this track should certainly follow.
It is important to find out to what extent the reduced methionine intake actually contributes to an increase in FGF21 levels.
In the future, the research team wants to carry out further studies with vegans to reveal additional evidence for possible involvement of methionine amino acids in the development of type 2 diabetes. T (AD)
