Elderly people should pay attention to their diet to prevent obesity

　　1. Prevent obesity

　　The increase in blood pressure is directly proportional to obesity, and obese people have a higher incidence of diabetes. Obesity promotes hardening of the arteries and is a cause of heart disease and stroke.

　　The cause of obesity is eating too much, taking in more heat energy than expending, and the remaining part is converted into fat and accumulates in the body. Over time, the cool and neat demeanor in middle age gradually turns into a staggering and pot-bellied image.

　　To prevent obesity, first don't eat too much. The amount of food you eat when you are young remains the same, but becomes excessive in middle-aged and old age. As you get older, your activities will decrease accordingly. Therefore, it is more important to move as much as possible to consume excess heat energy in order to prolong your life.

　　2. Supplement calcium

　　Among the foods we eat daily, although the supply of calcium is sufficient in most cases, there are many other factors in the food that affect calcium absorption, such as too much folic acid in plant leaves and stems, an inappropriate calcium-phosphorus ratio, etc.; the most important thing is elderly The function of the gastrointestinal tract is reduced, and the absorption of calcium is reduced accordingly. The amount excreted by metabolism does not decrease due to low absorption, but increases. It is often difficult for the elderly to heal after fractures. Calcium deficiency is a very important factor. Therefore, it is important to increase calcium intake in the food of the elderly.

　　3. Control salt intake

　　Many countries around the world promote low-salt diets to reduce salt intake as much as possible. Japan proposes that the appropriate intake of salt should be less than 10 grams. If the body is fit, a daily intake of 1 gram is enough to meet the requirements, but there is no taste when eating.

　　In the United States, dietary salt consumption is less than 5 grams. There are currently no standards in our country, but it is imperative to reduce salt intake. Especially for northern residents who are "heavy-mouthed" and like to eat salty food, more attention should be paid. In fact, this problem should be noticed from the time children start eating, but it is more important for the elderly.

　　4. Prevent iron deficiency anemia

　　Since our diet is mainly based on cereals, it is easy to cause insufficient iron supply in the body, which may lead to iron deficiency anemia over time.

　　Especially with female Anemia is more significant, and most of it is iron deficiency anemia. Anemia in young women is partly caused by dieting to maintain body shape; while a considerable number of young women are not eating well and are more susceptible to anemia due to physiological factors. Therefore, middle-aged and elderly people should pay more attention to this topic.

　　5. Eat more plant-based foods

　　Animal foods contain low fiber content and high saturated fat content, which is not beneficial to the elderly, so the elderly should eat plant foods. Increase fiber intake to prevent constipate It has certain significance with intestinal tumors.

　　Vegetable oil and animal fat should be supplied in a ratio of 2:1. Although both are fats, animal fat can increase blood cholesterol, while vegetable oil can reduce cholesterol, which is of great significance in preventing cardiovascular disease.
