① Meat: vegetarian = 1:4
It is suggested that there should be a ratio of meat to vegetables all day, which is roughly 1: 3 or 1: 4.
For example, eat a meat dish, a tofu, and two vegetarian dishes. It is best to eat a bite of meat first and then eat three vegetarian dishes.
② Coarse grains: flour and rice = 1:3.
In a day's staple food, it is best to have coarse grains around 1/4 ~ 1/3, which are rich in dietary fiber and have certain preventive effects on many chronic diseases. Potatoes, such as sweet potatoes, can replace some grains in moderation.
