My grandfather is 93 years old and still in good health. He told me that eating is a blessing. If it's a blessing, eat more. You can't eat too much. Eating too much is easy to get sick and accelerate the pace of aging. Only a reasonable diet can ensure a balanced nutrition.

As my grandfather, I told my grandparents, uncles and aunts that a reasonable diet is really important in our life. Eating according to the meal and eating the right things can ensure good health, avoid getting sick easily, and delay the aging of life. So, what is reasonable and what is diet? Simply put, how to eat three meals a day, when to eat and what to eat?

If middle-aged and elderly people want to live a long and healthy life, they must eat well, distribute three meals well, ensure proper intake of nutrients every day, and ensure that there are four categories of milk, meat, vegetables, fruits and grains in their daily recipes. Only in this way can they meet the nutritional needs of the body and avoid nutritional deficiencies such as osteoporosis caused by aging.

However, it should be noted that among middle-aged and elderly people, some important foods cannot be eaten, while some foods need to be supplemented. You should be confident, don't mess around, and avoid it. For example, middle-aged and elderly people with hypertension can't eat more fat. You should eat more celery and other foods to lower blood pressure.

Second, proper exercise.

Middle-aged and elderly people, like young people, should do exercise, relax the tibia, exercise the cervical and lumbar vertebrae, and prevent some sub-health diseases, such as cervical spondylosis.

So how to exercise properly? Middle-aged and elderly people should not do excessive exercise, just moderate exercise, and try not to do strenuous and high-risk exercise, such as simple morning running, Tai Chi, softball and square dance.

All of the above are physical exercises. Now let's talk about psychological exercises.

When people reach middle-aged and old age, they are easy to forget, and their brain cells are weak. So we should do some mental exercises, such as doing simple calculation problems, embroidering cross-stitch and playing chess, which can stimulate the cells in the brain and make them active.

Why middle-aged and elderly people can live a long and healthy life-besides reasonable nutrition, they should also exercise properly. In addition, the most important thing is to keep a normal heart and be less depressed. It is human nature to be born and die, so don't be sad, just ignore it.
