"Food, clothing, shelter, transportation" is the most important problem in people’s lives, and food safety is the most basic part of maintaining normal life. As the hottest topic in food safety issues- nitrite, its hazards Where on earth is it that all foods containing smoke nitrate cannot be eaten?
Nitrate is an assembly of inorganic compounds, including sodium nitrite and potassium nitrite. The nitrite in our lives mainly refers to sodium nitrite, a white to light yellow powder or crystal. The reason why nitrite "talks about salt discoloration" in people's lives is that after being absorbed by the human body, nitrite will undergo nitrosation reaction with the decomposition product amines of amino acid in the acidic environment of the stomach and produce carcinogen N -Nitroso compounds are harmful to human health. But nitrite itself is not toxic, even a legal food additive.
Nitrite is not uncommon, it is widely present in daily food and drinking water, and we often eat ham, sauce meat, bacon, fried food, overnight dishes, and pickles all contain nitrite. It exists as a preservative and color protectant.
In fact, the nitrite intake by the human body is not caused by unhealthy eating habits (high-salt diet, high-meat diet). Eighty percent of nitrite comes from eating vegetables. Plants use natural nitrogen to synthesize amino acids during their growth. In this process, nitrates are inevitably produced. Some reductases in plants will reduce part of nitrates to nitrites. These components will eventually be used as food. Absorbed by the human body.
Since nitrite is a food additive recognized by the country, can you rest assured to eat various foods containing nitrite?
The country has very strict regulations on the content of nitrite that can be contained in food.The market supervision and management department has also been strengthening the safety supervision and management of nitrite food, and there is no problem with normal consumption of various foods. However, the method of not talking about toxicity in terms of dose is wrong, so it is necessary to analyze the specific conditions of the intake of food dose.
We have pickles and pickles for a meal. The amount of is not much, but the amount of vegetables is larger. The nitrite content of green leafy vegetables is relatively high, the content is about 4 mg per kilogram. The human body’s safe one-time intake of nitrite is 0.2 mg per kilogram of body weight. You can calculate your weight. If you are a 50 kg normal male, your daily nitrite intake should be controlled at 10 mg. , Then the daily food intake should be controlled below 5 kg. If you are a person who loves vegetables, you should control your appetite a little bit.
In most cases, the nitrite contained in food will not cause great harm to the human body. As long as you maintain a healthy and normal eating habits, the ham and bacon in the supermarket can be assured food!
