We know that eating too much meat is bad for our health. For example, Americans eat a lot of meat and a little grain. In Japan, people eat a lot of grains and seldom eat meat. The incidence of cancer and heart disease in Japan is much lower. However, on the day when I moved to the United States, the incidence of heart disease and cancer would soar because their eating habits changed. There is also the popularity of high-fat foods such as hamburgers and ice cream, and the incidence of heart disease and cancer in Japan has risen sharply. In other countries, people also eat a lot of meat and milk, and the incidence of these places increases with people's growth. Dietetic experts everywhere advise people to eat more grains, fruits and vegetables and less meat and dairy products.
