Is the canned lunch meat nutritious?

The main nutritional components of lunch meat are protein, fat, carbohydrate, nicotinic acid and so on. The mineral sodium and potassium content is high, and the lunch meat is delicate, tender and fragrant. Lunch meat has high nutritional value and good taste. It is the product of high temperature and high pressure. High temperature process can sterilize, and high pressure process can also precipitate nutrients in meat. Without any preservatives, it can supplement protein and minerals for human body.

A small amount of preservatives-sodium nitrate and sodium nitrite were added to the luncheon meat. These salts are harmful to human body. Eating too much will make human blood lose its oxygen transmission ability, thus causing tissue hypoxia damage. Especially in the case of gastrointestinal dysfunction and excessive proliferation of nitrate-reducing bacteria in the intestine, eating too much lunch meat or lunch meat with sodium nitrite residue exceeding 0. 1% can cause symptoms of nitrite poisoning, such as headache, drowsiness, vomiting, abdominal pain, fever and shortness of breath, which is more harmful to children. Therefore, lunch meat should not be eaten more. Adding a small amount of sodium nitrate and sodium nitrite to meat products can play an antiseptic role. In addition, under acidic conditions, sodium nitrite will be reduced to nitrous acid, which will react with heme and myoglobin in fresh meat, making the meat become a pleasant rose red.
