What harm does eating more vegetables do to human health?

Some parents ask their children to eat more vegetables, especially meat dishes, thinking that meat dishes are nutritious and it doesn't matter if they eat less. Actually, it is not.

Although various foods in nature have different nutritional values, they have their own important functions and cannot be completely replaced by each other. If children only eat vegetables and don't eat, the intake of high-quality protein must first provide heat energy for the heat source, which can't play a more important role and is very uneconomical. If you eat vegetables at the same time, rice can provide heat energy, and high-quality protein in meat dishes can play a more important role in promoting children's growth and development. Therefore, children should be encouraged to eat more vegetables while eating, and nothing should be neglected.
