Is porridge really not nutritious?

As a staple food, it can still be eaten, but the glycemic index is high. If you only eat, you will be hungry soon and the nutritional density is too low. Even rice is mainly carbohydrate, with low protein and fat content. If you eat porridge, it must be thick. The soup with porridge is not as good as drinking water, at least there will be less arsenic. And be sure to eat some eggs, vegetables and the like, otherwise it is simply unhealthy. Let's eat KFC McDonald's, at least some meat, eggs, cheese and lettuce.
