The first is pickled food. Pickles and pickles in supermarkets are all pickled foods. Pickling is mainly to prolong the shelf life of food, which is delicious and convenient to eat. But in fact, in the production process, food will produce a lot of nitrite, which is highly carcinogenic. If you eat too much, it is easy to cause chronic poisoning and even cancer.
The second is alcohol, which is a carcinogen and may bring high cancer risk to human body. People over 50 years old have decreased liver and gastrointestinal functions. If they continue to drink alcohol, it will have a great impact on liver function and gastrointestinal digestion. In addition, many elderly people have a history of chronic diseases such as hypertension. Drinking alcohol may cause cardiovascular and cerebrovascular diseases and increase the incidence of cardiovascular and cerebrovascular diseases, which is very harmful to the body.
The third is bone soup. Many middle-aged and elderly people like to use bone soup to supplement calcium. They think that bone soup contains a lot of calcium, which can play a good role in supplementing calcium, thus preventing osteoporosis. But in fact, the calcium in bone soup is very low. In the process of cooking soup, calcium in bones is difficult to dissolve in soup. Not only is the calcium content low, but also there is a lot of fat. Middle-aged and elderly people drink too much bone soup.
Fourth, the leftovers themselves will not cause harm to the body. But if you don't eat leftovers for a long time, you will produce a lot of nitrite. If absorbed by the human body, it will lead to cancer. If you often eat leftovers, it will cause gastrointestinal discomfort, which will lead to stomach diseases and even gastric cancer. In daily life, it is not uncommon to misunderstand diet. Not only middle-aged and elderly people, but also some young people are in danger of eating because of wrong ideas, which is undoubtedly a warning to people. Scientific health preservation and reasonable diet are the most important. Ok, that's all for today.
