1. If you want to stay healthy, you need to change the eating habits of the elderly. Old people should pay special attention to their diet. Because these people's digestive function and metabolic function are not as good as those of young people, they must not be taken lightly in food selection. Ensuring a balanced diet is easier said than done. It is very important for health care to maintain an appropriate proportion of carbohydrates, meat, fruits and vegetables every day. Old people must drink plenty of water if they want to promote the excretion of toxins in their bodies. Many elderly people will be constipated because of the decline of gastrointestinal function. In order to prevent this from happening, it is recommended to consume about 2000ml of water every day.

2. Moderate exercise can not only strengthen bones, but also promote bone growth. Old people should often do some sports within their power, such as jogging and cycling. The elderly must pay attention to the eating rules, don't overeat, have a light diet, mix vegetarian food with nutrition, and do some exercise properly in order to live a long and healthy life. People over the age of 60 should take 10 microgram of vitamin D every day and bask in the sun for 20 minutes, which can improve immunity and bone health. The elderly can supplement nutrition through a scientific diet, such as supplementing high-quality protein with fish and shrimp meat, or taking calcium and nutrients needed by the human body from bean products and dairy products, which is beneficial to the health.

3. The elderly must pay attention to the rule of three meals, eat well for breakfast, eat as little as possible for dinner, and appropriately supplement foods containing high-quality protein, such as milk, soybean milk, eggs, lean meat and fish. Also, you should supplement appropriate fruits and vegetables, and try not to eat too greasy and fried food. Control your emotions: Middle-aged and elderly patients with cardiovascular diseases should control their emotions. When they are emotional, their blood pressure and blood sugar will rise, which will increase the pressure on blood vessels and lead to accidents. Old people can choose to take a walk one hour after meals, play Tai Ji Chuan, do exercises and other activities, which will help them to exercise and improve their immunity.
