Mother-in-law always leaves the leftovers for herself to eat, and she is not happy when we pour them. How can I convince her?

? Nowadays, the elderly generally live frugally, which is a habit they have formed, but leftovers will do great harm to people's health.

? Leftovers left in the refrigerator for a long time will be contaminated by common pathogenic bacteria or dust. If you take it out of the refrigerator and eat it directly, or if you don't heat it enough before eating, it will lead to food poisoning. The patient has symptoms of fever, nausea, vomiting and diarrhea, and in severe cases, dehydration, acidosis or shock may occur. Moreover, the content of nitrite in leftovers will gradually increase with the extension of storage date, and nitrite is a strong carcinogen. Eating leftovers often increases the risk of digestive system tumors such as gastric cancer, esophageal cancer and liver cancer.

The amount of meals prepared in court every day often exceeds the actual needs, fearing that the waste will be swallowed reluctantly, leading to overeating. If the energy intake exceeds the actual needs of the human body for a long time, it will lead to obesity over time. Obese people are prone to high blood pressure, hyperlipoproteinemia, coronary heart disease, diabetes, gallstones, cancer and other rich diseases, which affect people's quality of life and shorten their life span. The nutrients in it have almost disappeared. If you eat this kind of food regularly, you will easily lose your physique and suffer from malnutrition.

? Old people, children or patients, especially gastrointestinal patients, eating leftovers is like adding insult to injury and harmful to health. After a period of time, the leftovers with decreased appetite can't maintain the original level. If they are cooked at high temperature, they may be unrecognizable and become a pile of soft, boring and tasteless hodgepodge. Eating such food often will make people lose their appetite and lose the fun of eating.
