What are the dangers of canned food

There are many kinds of canned foods, and they are sold in many places. There are canned fruits and some canned meats. For most people, canned foods taste better and are more convenient. However, we cannot ignore the harm of canned food, which is not good for the human body. Although canned food is very convenient, it is not recommended for people to eat canned food frequently. Canned food is definitely not as nutritious as natural food, so you should eat less canned food.

Canned food is sterilized by heating at a high temperature and high pressure of 121°C. Therefore, the protein in canned products often denatures, which greatly reduces the body's digestion and absorption function, causing a substantial "shrinkage".

It destroys vitamins

The vitamins in canned fruits and canned meats will be destroyed to a great extent. Relevant research data show that during canning, the vitamins in meat, including vitamin B1, vitamin B2, vitamin B5, vitamin B6 and folic acid, will suffer a certain loss. Especially vitamin B1, because it is easily destroyed when exposed to heat, it can lose 15% to 25%, vitamin B2 can lose 10%, and vitamin B5 can lose 20% to 30%. The vitamin C in canned fruit will be almost completely destroyed.

High sugar levels put a heavy load on the pancreas

Many canned fruits have a lot of sugar added to enhance the taste. When these sugars are ingested by the human body, they can cause obesity due to their high energy content. At the same time, it can cause a sharp increase in blood sugar in a short period of time and increase the burden on the pancreas. In addition, the study also found that sugar can change the molecular structure of protein, thereby affecting immunity.

Many people have eaten canned food. Because there are different types of canned food, people have many different definitions of canned food. There are many harmful effects of canned food, but people don’t pay much attention to it. The nutritional value of canned food is not as good as that of natural food, so we should eat less canned food. Many people have poor health, and eating canned food will affect their resistance.
