Food additives can't be killed by a stick, but acidity regulators, anti-caking agents, defoamers, bleaches... these don't sound like healthy ingredients. What are the food additives?

Among the many food additives, the most popular ones are the preservatives. People seem to have talked about the degree of preservative discoloration. In fact, preservatives are not so "flooding beasts", and do not easily believe that the business "does not contain any preservatives" guarantee. The main role of preservatives is to inhibit the growth of microorganisms (including bacteria, fungi, viruses, etc.) in foods and to extend the shelf life of foods. The effects of food spoilage on the human body are far greater than the preservatives. The food preservatives allowed in China are low-toxic and safe. They have undergone a large number of animal experiments before, which proves to be very safe for the human body, as long as the manufacturers are strict. Adding according to national standards will not cause damage to human health, and can be safely eaten.

But does this mean that we can ignore the preservatives on the ingredients list? Of course not! There is a toxicology famous saying "dose is toxicity", and the big vernacular of the people is "the salt eats more and still dead", so What should be paid more attention in daily life is not to absolutely eliminate preservatives, but to pay attention to daily intake.

Sodium benzoate (benzoic acid) is our most familiar preservative. You may also want to see if there is any figure in the ingredients when you buy soy sauce. Then you must know that sodium benzoate is an alias for sodium benzoate, benzene. Sodium formate preservation is suitable for acidic foods.

Among the common preservatives, sodium benzoate is a relatively harmful hazard to humans. There are reports of cumulative poisoning of sodium benzoate. Fortunately, sodium benzoate can be metabolized in a day or two and generally does not accumulate in the body. . Based on the daily allowable intake of sodium benzoate, an adult weighing 50 kg can consume up to 250 mg of sodium benzoate per day. According to national regulations, a bottle of soy sauce contains up to 500 mg of sodium benzoate, which means that half a bottle of soy sauce will be poisoned at a time. Therefore, it is really unnecessary to care too much about whether sodium benzoate is contained in soy sauce.

However, sodium benzoate is widely used and cannot be taken lightly. Let's take a look at the ingredient list for sugar-free cola, which clearly indicates that it contains sodium benzoate. Approximately 0.5 kg of sugar-free cola may contain up to 100 mg of sodium benzoate, which is less than half of the maximum daily intake of sodium benzoate (250 mg) for a 50 kg adult. But what if you drink two bottles a day? Coke does not leave your hand? Children who are light weight? It is estimated that it may exceed the standard, not to mention the inevitable consumption of other foods containing preservatives every day. It seems that sugar-free cola is still a good drink.

Look at the fruity drink, the content of sodium benzoate may be higher, if the daily consumption exceeds the standard, it will inevitably have adverse effects on the body. (Zhang Qian, Yunmo)
