Will you lose your muscles and increase fat? Will whole wheat bread lead to sarcopenia? The professor reveals the truth

Reader Mr. Li used the website's "Contact Me" on 2023-6-19 to inquire:

"Hello, Professor Lin. Recently, I saw an article on the newspaper that germ glutenin (WGA) can cause sarcopenia. Is this statement correct? I really want to hear the opinions of your experts. With this short article, thank you."

The article he attached was published on 2023-6-13 on the China News Network. Sarcopenia is a brain-harm and fat-harm. The doctor name is "1 Healthy Food" that causes muscle loss and fat. I copied part of the germ egglutinin about the germ egglutinin as follows: "Li Siqin, a medical physician, said in his face that the other hand that makes sarcopenia is germ egglutinin (WGA). Li Siqin said it is a very small protein, even if humans are Without kidney disease, it will also enter the body. WGA makes the muscles unable to get the appropriate glucose, which makes the glucose transform into fat, which will harm people to reduce muscle and increase fat. He also said that WGA does not exist in white bread, but only in the whole wheat bran of whole wheat bread, so if you eat whole wheat bread for health, you may Get the reverse effect. ”

I went to Dr. Li Siqian's face to check it out and saw that his article "Milk Germ Germ Causes Sarcopenia" has 467 comments, 43 comments, and 59 sharings. One of the messages was "Can Yan Mai have any?", while Dr. Li Siqin's answer was "Yes". (Note: Regarding the deliberate smear on the Internet, please see what I published last month that the more I eat, the more sick you get?)

The English word for sarcopenia is sarcopenia, while the English word for germ agglutinin is wheat germ agglutinin. So I searched PubMed in Google and Public Medical Library with these two keywords and the result was zero.

I have seen articles about sarcopenia published by Cliffland clinics, and there is no mention of whole wheat bread or germ glutenin that can cause sarcopenia.

I read two more articles about sarcopenia that were published just this year, and they did not mention that whole wheat bread or germ glutenin can cause sarcopenia. Please see

Epidemiology of sarcopenia: Prevalence, risk factors, and consequences

Insights into Pathogenesis, Nutritional and Drug Approach in Sarcopenia: A Systematic Review

When I searched for health effects of whether sarcopenia is harmful to health, I found a summary of health effects of wheat lectins: A review (The impact of microscopic lectin on health: a summary). It says in the abstract: "A part of the protein present in the microbial germ is expressed as microbial germ lectin (WGA). Some popular nutrition planners have proposed the adverse health effects of this microbial lectin. So we carefully reviewed the latest research on the mechanisms of microbial lectin affecting health factors such as obesity, autoimmune diseases and chylo. Our conclusion is that there are many uncertified hypotheses." Currently data on the health effects of dietary lectin does not support negative effects on human health. On the contrary, eating foods containing WGA, such as grains and whole grain products, has been shown to significantly reduce the risk of type 2 diabetes, cardiovascular disease, certain types of cancer, and improve long-term weight management. "

I also found a summary article published last year Bioactive Components in Whole Grains for the Regulation of Skeletal Muscle Function (a bioactive component that regulates skeletal muscle function in whole grains), which contains this passage: "It has been clearly seen that whole grains and whole grain products have great nutrition and health-promoting properties because the germ and cervical part contains unique bioactive ingredients (dietary fiber, β - glucosaccharide, phenolic, phenolic, citrus, citrus and tocotrienol). "

Whole grains: Hearty options for a healthy, published by the well-known mercury clinic diet (Full grain: A healthy diet choice) said at the beginning: "Full grain foods are a good choice for nutritional diets. Full grain provides fiber, vitamins, minerals and other nutrients. Full grain foods help control cholesterol levels, weight and blood pressure. These foods also help reduce the risk of diabetes, heart disease and other diseases..

The Dietary Guidelines for Americans 2020-2025 (Dietary Guidelines for Americans 2020-2025) published by the U.S. Government has this paragraph on page 23: "The common characteristics of dietary patterns related to the optimal health results include relatively high vegetables, fruits, beans, whole grains, ……"

The Chinese Community Health Resource Center has this paragraph: "The benefits of eating whole grains: All grains contain rich vitamins. Group B, minerals, and fiber. They belong to natural low-fat foods. Eating whole grain foods may reduce the risk of certain chronic diseases; including heart disease, diabetes, and certain cancers. So, are you going to trust these medical papers and trustworthy health information, or are you a face article that Li Siqian has no scientific evidence?
