Nutrition during breastfeeding is very important, as mothers have to gradually replenish their nutritional reserves depleted by pregnancy and childbirth, secrete milk and bear the burden of nursing their babies, so adequate nutrition is very important during this period. If the mother is not well nourished, it will not only affect the mother’s health, but also reduce the quality of milk and affect the growth and development of the baby. Therefore, a proper diet is very important for the lactating mother. During breastfeeding, mothers should pay attention to the following points in their dietary arrangements: 1. They should try to have a complete variety of food, not to be partial, and increase the quantity accordingly to ensure that they can consume enough nutrients. This means that the staple food in a lactating mother’s diet should not be single, and the side dishes should be diversified, with coarse and fine grains in combination. 4~5 meals a day is appropriate, and some mixed grains, oats, millet, adzuki beans, mung beans, etc. should be appropriately deployed. Doing so can ensure the supply of various nutrients, but also make protein to play a complementary role, to improve the nutritional value of protein. 2, supply sufficient high-quality protein. Animal foods such as eggs, poultry, fish, etc. can provide high quality protein and should be consumed more often. Lactating mothers should ensure that more than 1/3 of their daily protein intake comes from animal foods. Soy foods can provide good quality protein and calcium, and should be fully utilized. 3. Eat more calcium-rich foods. Lactating mothers need a lot of calcium and need to pay special attention to supplementation. Milk and dairy products (such as milk and yogurt) contain the highest amount of calcium and are easily absorbed and utilized, so a certain amount should be supplied daily. Fish, shrimp, dark green vegetables and beans can also provide a certain amount of calcium. 4.In order to prevent anemia, you should consume more foods with high iron content, such as animal liver, meat, fish, rape, spinach, soybeans and their products, etc. 5.Adequate intake of fresh vegetables, fruits and seaweeds. Fresh vegetables and fruits contain a variety of vitamins, inorganic salts, fiber, pectin, organic acids and other components, some regions have the habit of forbidden to eat vegetables and fruits after childbirth, should be corrected. Seaweeds can also supply the right amount of iodine. These foods can increase appetite, prevent constipation and promote lactation, and are indispensable foods in the daily diet of lactating mothers, which should be supplied at least 500 grams per day. 6. Eat less salt and salted foods, stimulating foods (such as certain spices), and contaminated foods. Do not smoke, drink alcohol, drink coffee or take certain drugs for a long time. 7, pay attention to cooking methods. For animal food, such as livestock, poultry, fish cooking methods to boil or roast as the best, less fried. When cooking vegetables, pay attention to minimize the loss of vitamin C and other water-soluble vitamins. Special attention needs to be paid to the frequent consumption of some soups, such as chicken, duck, fish, meat soup, or tea soup made from beans and their products and vegetables, which can increase nutrition, but also replenish water and promote lactation. For lactating women, the daily intake of calories, protein, fat and carbohydrates should be about 12545 kJ, with a caloric ratio of 13%-15% for protein, 27% for fat and 58%-60% for sugar. However, after one month, it returns to the pre-pregnancy level, and these quality foods should be dispersed in the later months of lactation so as to contribute to the quality of milk and the growth and development of the baby.
