"MSG is chemically synthesized, and excessive additives can cause cancer!"
Aunt Wang deeply hates MSG, stir-fry never put MSG, feel that MSG has too many additives, eating is not good for the body. However, the daughter-in-law who entered the door always likes to put MSG when cooking, and specially bought a package to put in the kitchen, and Aunt Wang reminded the daughter-in-law after throwing it away.
"But the stir-fry dish is not delicious without MSG, and the things that can be put out and sold are fine with state supervision." The daughter-in-law felt that Aunt Wang was a bit fussy and protested loudly.
"I'll buy you another bag tomorrow, I won't eat it anyway." Aunt Wang's face was cold, and her tone was a little rushed.
"Forget it, MSG so many additives, eat dry mouth, it is definitely not good for the body, do not use it." The son hurried out to fight the round field, and the daughter-in-law was angry, and a family war broke out.
In fact, this is the epitome of many families, CCTV has done a survey, many people and Aunt Wang have the same concerns, because they are afraid that MSG is a chemical product that causes cancer and does not use MSG. Today, Xiao Ai will help everyone "pickpocket" the most common condiment of this family, what is the harm of MSG.
First, the explosion of MONOSG additives will cause cancer?
MsG has the same status as oil, salt, sauce and vinegar, and is one of the most common seasonings in the kitchen. CCTV once broadcast a special program detailing the production process of monosodium glutamate, although MSG has a "fine" word, but it is a white crystal condiment made of carbohydrates (corn, soybeans, molasses, etc.) as raw materials, after fermentation, extraction, neutralization, crystallization, separation and drying. It can be said that MSG is the purification of food, not chemical products.
MONOSodium glutamate itself is a food additive, the main ingredient is sodium glutamate, as well as a small amount of salt, water, fat, sugar, iron, phosphorus and other substances. According to the "National Standard for Food Safety", sodium glutamate can be used in an appropriate amount in production, and monosodium glutamate and glutamic acid are safe flavor enhancers. Sodium glutamate is essentially a monosodium salt of glutamate, which is one of the amino acids that make up proteins, is an essential nutrient for the human body, and does not have toxicity.
Professor Hu Xiaosong, vice president of the Chinese Society of Food Science and Technology, said that after more than 20 years of scientific verification, monosodium glutamate and sodium glutamate are completely safe and reliable. That is to say, the explosion of MSG additives will cause cancer, which is nonsense.
Second, the use of MSG, is there really no health risk?
In this way, MSG is really not a "harmful essence", does that mean that there is no limit to "refilling cups"? And slowly, if you eat MSG without reducing the intake of other sodium salts such as table salt, it will also have a bad impact on the body.
In addition to "fresh", MSG will also have a salty taste. This is because it contains "sodium" like salt. The safe intake of sodium in the human body is 1000-2500mg, which is equivalent to about 2.5-6g of table salt. If you have put a lot of salt at the same time as stir-frying, adding MSG at this time will easily cause sodium to exceed the standard. Exceeding the safe amount, people will feel dry mouth, dry tongue, numb lips, rapid heartbeat, etc., and long-term sodium exceeding the standard will also increase the risk of cardiovascular disease, stomach cancer and so on.
Third, the use of MSG, you need to pay attention to these three points
The addition of MSG makes the flavor of the dish more delicious and satisfies the tip of our tongue. So, when cooking, how to "apply" MSG in place?
1, use up to 5g per day
As with salt, the amount of MSG eaten should also be limited. Adults should not consume more than 5g of MSG per day, and the blood vessels of infants and young children are fragile, so it is best not to consume MSG.
2, stir-fried meat without msg
Meat contains natural glutamate, in fact, without adding MONOS glutamate, itself can also release a special "umami taste". Therefore, when cooking meat products, there is no need to place MSG.
3: Put it before cooking
The structure of MONOS glutamate is not very stable, when the temperature exceeds 80 ° C - 100 ° C, it will dissolve and volatilize, when it exceeds 100 ° C, it will lose its umami taste. Therefore, when making dishes or soups, it is best to wait until it is close to the pot before pouring MSG.
Fourth, which foods should really be paid attention to because of additives?
Food safety has always been the most concerned issue for all mankind, and some illegally added food additives will make food look shiny and attractive, but there is a hidden carcinogenic risk behind it.
1. Titanium dioxide ice cream
A recent study by Nutrition Frontiers found that titanium dioxide in foods can have a negative impact on the human body, including inducing colon cancer. According to Professor Wojciech Chrzanowski of the University of Sydney in Australia, titanium dioxide is usually found in ores, sand, and soil, and was first used to process paints, ceramics, and cosmetics that can emit bright white. As an ideal brightener, it was later used in milk, ice cream, and cakes. Titanium dioxide works only to look good, has no nutritional value, and lacks safety evidence.
In this study, the researchers gave groups of mice a regular diet or a diet mixed with titanium dioxide. The results found that titanium dioxide forms a biofilm in the large intestine, negatively affecting the intestinal flora, while mouse macrophages increase CD8, helper T cells Th17 increase, and inflammatory cytokines in the colon rise. It can be seen that long-term intake of titanium dioxide will destroy the intestinal environment and increase the risk of bowel cancer.
Due to the extreme safety hazards of this ingredient, the French Safety Agency has banned it, and the European Union will ban the use of the compound as a food additive in 2022.
2. Potassium bromate bread
In the past, the improvement agent of potassium bromate was widely used in bread, which had the effect of whitening and strengthening ribs, which could make the baked bread whiter and more expanded; it tasted softer and more elastic, but it has been banned because of safety.
Ma Zhiying, director of the Food Safety Professional Committee of the Shanghai Food Society, said that there are studies that found that potassium bromate does have certain toxicity and carcinogenicity, and China has banned the use of potassium bromate as a flour treatment agent in wheat flour in 2005. Therefore, when buying bread, netizens must buy it in formal channels, do not covet cheapness, and buy bread with unknown origin and unknown composition.
When it comes to food additives, we have to look at them dialectically. To say that MSG is "harmful essence", it may be to add some MSG, the dish is too delicious, unconsciously eat more, let people become fat. So, no matter what you eat, or eat it occasionally, don't overdo it.
