Protein: Mainly derived from animal protein and plant protein. The daily nutritional requirement of pregnant women is 75- 108g.
Animal protein is mainly fish, lean meat, eggs and milk. Besides protein, these foods are also rich in vitamins, minerals and saturated fat.
Plant proteins include beans, rice, wheat, nuts and seeds. These foods are ideal for pregnant women, but they should be properly matched. For example, you can eat meat instead of milk every day, or you can eat 2-3 eggs or drink 200-250 ml of milk every day. If other foods are rich in protein, you don't have to eat animal protein every day.
In a word, it will be better to mix animal and plant proteins reasonably.
