With the increase of age, people's physical function gradually declines. Therefore, having a healthy body is becoming more and more important. However, with the improvement of living conditions, many elderly people today suffer from "three highs" due to improper diet. In order to avoid these situations, we need to master some reasonable and healthy dietary standards. Only by eating scientifically can the body be healthy and the body functions such as immunity be more stable.

So, how should the elderly eat and keep healthy? Economic Daily-China Economic Net shares some suggestions with you today. Let's see friends with old people at home.

Avoid overeating

Every function of the elderly body is slowing down, and the speed of body metabolism is also gradually slowing down. If you eat too much or eat too much for a long time, too many calories in your body can't be consumed, and it will accumulate in the liver in the form of glycogen. If it can't be digested in time, it will turn into fat and make people fat. Obesity is the precursor of a series of diseases such as arteriosclerosis, coronary heart disease and diabetes. Moreover, food stays in the stomach for too long, which is easy to cause indigestion and makes people very uncomfortable.

Avoid greasy food.

The elderly should have a light diet and eat less high-fat and high-cholesterol foods such as fat meat, fried food and animal offal. Because too greasy food is easy to cause hyperlipidemia, hypertension and diabetes, and it is very harmful to cardiovascular and cerebrovascular diseases of the elderly, and may even further develop into coronary heart disease. Therefore, it is suggested that the elderly should try to avoid eating greasy food.

Avoid pickling food.

Pickling is a very effective method to preserve vegetables in the early stage. Nowadays, the pickling of vegetables has changed from a simple fresh-keeping method to a processing technology of vegetable products with unique flavor. However, vitamin C in pickled food was destroyed in large quantities, and the nutrient loss was serious. Because preservatives, color enhancers and color retention agents are added, eating too much will increase the burden on the liver and is not suitable for the elderly.

Avoid cold food.

The function of the elderly gradually declined, the digestive function of the gastrointestinal system declined, and the secretion of gastric acid and various digestive enzymes began to decrease gradually. Cold food has a strong stimulating effect on digestive tract mucosa, which is easy to cause diarrhea or digestive tract inflammation. If the elderly often eat cold food, it is likely to cause gastric mucosal vasoconstriction, further reduce gastric juice secretion, leading to decreased appetite and indigestion.
