Fu Shuo, a doctor in the Department of Nutrition and Health Care of Hainan Provincial Hospital of Traditional Chinese Medicine, said that although bamboo charcoal itself has adsorption function, it can be placed in a room or refrigerator as a moisture absorbent and deodorant, but the adsorption performance of bamboo charcoal is different from the principle of adsorbing human endotoxin. The so-called function of "adsorbing toxins in the body" is not credible and belongs to false propaganda.
Metabolites in our body, such as urea, uric acid, etc., can be excreted in the form of urine through the kidneys when the renal function is normal, and a small amount will also be excreted through feces. Therefore, only when there is something wrong with our kidneys and the excretion of metabolites cannot be completed, that is, renal insufficiency or even uremia, doctors will use medical activated carbon for patients to absorb excessive metabolic waste in the body, promote the excretion of metabolites, reduce the retention time of creatinine and urea nitrogen in the body, and reduce reabsorption, thus reducing the burden on the kidneys, reducing the concentration of toxic substances in the blood, and preserving healthy nephrons. For normal people, activated carbon, as a foreign body, will creep into the intestine after being swallowed in the stomach, and basically be excreted as it is. Can not play a very good role, but also affect the absorption of nutrients, causing indigestion, constipation and other problems.
Moreover, it is illegal to add bamboo charcoal as an additive to food. The Hygienic Standard for the Use of Food Additives stipulates that plant carbon black can be used as a colorant in the production and processing of candy, rice products, wheat flour products, cakes and biscuits; Plant activated carbon can be used as a processing aid in food industry, but it should be removed before making the final product. Neither plant carbon black nor plant activated carbon can be used in tea production and processing. The key point here is that "plant activated carbon should be removed before the food is made into the final product". Bamboo charcoal can't be used as food raw materials, and it has not been listed as a legal additive in the Standard for the Use of Food Additives (GB2760-20 1 1). Therefore, "bamboo charcoal food" is actually food processed with materials that are not allowed by the state. At the same time, its detoxification function and safety in human body have not been scientifically and effectively verified, so consumers should buy and eat it carefully.
At the same time, the possible side effects of bamboo charcoal food can not be ignored. Eating a lot of food containing activated carbon may cause gastrointestinal discomfort or constipation. It may also be mixed with some impurities or harmful substances, which may cause harm to health, such as affecting normal digestion and absorption, and even causing malnutrition. Eat as little or no bamboo charcoal food as possible, because it is "illegal food". For people with indigestion or malnutrition, it is best not to eat these black foods. The US Food and Drug Administration (FDA) has warned that foods containing activated carbon may bring health risks, and cities such as new york have banned the sale of black foods containing activated carbon.
Finally, I tell you that in daily life, in order to achieve the effect of detoxification and beauty, people should have a balanced diet and eat more fresh fruits and vegetables and coarse grains on the basis of ensuring a balanced variety of food. Fresh fruits and vegetables have high nutritional value and are rich in dietary fiber, which is beneficial to defecation.
