It is better to eat foods containing protein, vitamins, calcium and iron during breastfeeding. Women who are breastfeeding should have a balanced diet to ensure lactation and have a higher demand for nutrients, so they can eat more foods with higher calcium and iron content, such as pork liver, beef, red meat, and dark-colored vegetables, to replenish nutrients for the body. Breastfeeding women can also eat more protein-rich foods, such as milk, eggs, beans, fish and other foods, to replenish protein. Breastfeeding women also need to consume more fruits and vegetables to replenish vitamins and to ensure balanced nutrition. Women who are breastfeeding should abstain from smoking, alcohol and coffee, and also make dietary adjustments under the guidance of a medical professional.
