Don't eat high-fat food. Many people are prone to get some diseases such as high fat and high blood sugar after middle age, so we should never eat those high-fat foods after middle age.
If we often eat high-fat food, it will lead to blockage of our blood vessels or other obesity diseases. For example, the fat meat or greasy fried things we usually eat are not suitable for the elderly.
Don't eat too salty. Usually advocate a light diet, light diet. Besides not eating high-fat food, don't eat too salty food at ordinary times.
When I cook at home, I try to put as little salt as possible. Although I am still young, my food is not so salty, but my food is very light. I think health care should start from an early age, regardless of age. What's more, people's health is not as good as before when they are old, and they should pay more attention to their diet.
A low-sugar diet. I found that many diabetics are generally above middle age, and young people rarely get diabetes. So if you reach middle age, you should try to eat less foods with high sugar content, such as desserts or sweets, and try to eat less.
Avoid spicy diet. Usually when we get sick and catch a cold, the doctor will tell us not to eat spicy food, and the most important thing is to avoid it. In fact, when people are old, it is best not to eat spicy food, because spicy food really hurts the stomach.
