It is best for pregnant women to have a nutritionally balanced meal for lunch that contains adequate amounts of carbohydrates, proteins, vitamins and other substances. There is a slight difference in diet between the early and late stages of pregnancy. Early pregnancy does not require an additional increase in energy, while after the fourth month of pregnancy, it is recommended to increase energy by 200kcal per day on top of the original, based on which lunch can be considered to increase by 100kcal on top of the original. Protein and carbohydrates are both needed for lunch during pregnancy, so avoid cutting back on carbohydrates in an attempt to lose weight, or consuming too much meat in order to replenish protein. Include vegetables in your lunch during pregnancy to help improve constipation, and consider consuming more folic acid-rich substances such as animal liver or dark green vegetables, etc. Try not to consume preserved foods and stimulating foods in your lunch during pregnancy. You can eat a normal lunch during pregnancy without worrying too much about what you can’t eat, but if you have nutritional problems, you can also see a hospital nutritionist to adjust your diet.
