Eating fruits and vegetables can not only supplement vitamins, minerals and other essential nutrients to prevent intestinal cancer, but also improve mental state and prevent diseases. A study by the University of Warwick in the United Kingdom shows that people who eat 7 servings of fruits and vegetables (about 85g each, the weight of a medium-sized banana) have the best mental health. Eating more fruits and vegetables can improve life satisfaction, mental health and happiness.

2, insist on taking a nap every day

There is a simple reason. Taking a nap during the day gives the brain and physical strength time to repair, temporarily puts down work, releases stress, and restores the brain to a more focused state. It is advisable to take a nap for about a quarter of an hour during the day, not too long.

3. Walk for at least 7 hours a week.

The American magazine Nature once reported that people over 60 can prevent Alzheimer's disease by walking for more than 45 minutes three days a week. Walking for more than 7 hours a week can reduce the incidence of breast cancer by 20%. Wearing a pair of light sports shoes, going out for a few laps every morning and evening, moving your legs and swinging your arms steadily are good for cardiovascular and even general health.

4. Ensure a fish every week.

Fish contains a lot of omega-3 fatty acids, which helps to improve brain health and memory. For people over 65, eating fish can also reduce the risk of Alzheimer's disease.
