Recently, an article entitled "The Severity of Vitamin Deficiency" recommended by Professor Nie from peking university health science center has been widely circulated on the Internet. The article thinks that the chief culprit of cancer is the lack of vitamin B2. In addition, there are many diseases due to the serious lack of vitamin B2. The article also suggested that people should "supplement vitamin B2 in time and in sufficient quantity", but experts in Xicheng said this statement was unscientific.

Lack of vitamin B2 can cause cancer? A little exaggerated

This article points out that epidemiology believes that parents have cancer and children are prone to cancer, so cancer is hereditary, which is actually a wrong conclusion. The real reason is that parents and children are highly similar in diet structure, and the long-term serious lack of vitamin B2 in the body is the root cause of cancer and tumor.

"We know that vitamin B2 is a water-soluble vitamin, and vitamin B2 supplementation is also the content of primary prevention of cancer, but it is somewhat exaggerated to regard the lack of vitamin B2 as the chief culprit of cancer." Liu, director of the Oncology Department of the Municipal People's Hospital, said that at present, no patients with cancer caused by vitamin deficiency have been found clinically. The cause of cancer is very complicated, which is closely related to the environment, food, living habits and so on. You can't just emphasize one factor.

Liu Ye disagrees with the statement that cancer cannot be inherited. "Medicine has proved that cancer has genetic susceptibility, and people with family inheritance have a relatively high probability of getting sick. For example, some breast cancer patients were originally right breast cancer, and ten years later, the left side also became ill. Eighty percent of these patients are inherited in the family. "

Causes ulcers, angular stomatitis, hemorrhoids ... these are all true.

Besides cancer, the article also points out that vitamin B2 deficiency is the cause of many diseases. In this regard, Zhou, the chief physician of the Nutrition Department of the Municipal People's Hospital, agreed. She introduced that vitamin B2 deficiency will affect the biological oxidation of human body and make metabolism disorder. The prominent feature is various inflammatory reactions. For example, patients with vitamin B2 deficiency often have inflammatory reactions, such as bursitis and angular stomatitis.

In addition, vitamin B2 deficiency may also cause symptoms of skin and eye diseases. In patients with vitamin B2 deficiency cystitis, besides scrotal skin exudation, erosion, desquamation, scabbing, chapped and other symptoms, there are also a series of changes such as infiltration, thickening and wrinkles. Some patients showed glossitis, which initially showed purple-red tongue color, cleft tongue and hypertrophy of tongue nipple, followed by irregular erosion, common on both sides of tongue, and tongue pain. If the pharyngeal mucosa is involved, it can also be manifested as pharyngeal inflammation and sore throat. Many people with vitamin B2 deficiency show cheilitis, mainly manifested as early mucosal edema of the lips, and even severe mucosal atrophy of the lips.

A normal diet can meet the demand.

As one of 13 essential nutrients, vitamin B2 is a component of many enzymes, which can promote development and cell regeneration. It is understood that with the improvement of people's health awareness, the consumption of nutrition and health products in Wuxi is on the rise. Many citizens usually buy vitamin B2. In this regard, Zhou believes that vitamins are widely found in foods such as milk, eggs, meat, animal offal, cereals, vegetables and fruits. "In the past years of poverty, there were only Chinese cabbage, potatoes and radishes in winter and spring, and the human body may lack vitamin B2. But now the standard of living is getting higher and higher. Under normal circumstances, vitamin B2 taken from food can meet people's needs without special supplementation. " Liu said that only special groups such as malnourished patients and the elderly need to take health care products as nutritional supplements because they can't get enough vitamins and minerals from their diet. In addition, many children will encounter serious partial eclipse in clinical work, and they don't like to eat animal protein and fresh vegetables and fruits, which leads to vitamin B2 deficiency in the body. In this case, it can be supplemented appropriately.

Excessive supplementation can also have side effects.

Although vitamin B2 is very important to human body, it is not recommended indefinitely as a micronutrient. According to the recommended amount of vitamin B2 of China Nutrition Society, it is 65438 0.4 mg/day for adult males and 65438 0.2 mg/day for females. "In fact, from beneficial to harmful, from tonic to medicine, it is often a matter of' eating more'." Zhou explained that people's physiology is extremely complex and needs the support of various nutrients, and the functions of various nutrients are different, and the needs of the body are also different. These nutrients interact with each other in the body, or promote absorption with each other, or resist each other, so it is impossible to react alone. It is as wrong to overemphasize the physiological function of a nutrient as it is to overemphasize the demand for a certain food. Excessive intake of vitamin B2 will affect the absorption or utilization of other nutrients, and long-term excessive intake will definitely be harmful to the body.
