There are two kinds of fennel, seasoning and edible vegetables, which should generally be eaten sparingly during breastfeeding to avoid affecting the health of breastfeeding women and babies. Fennel, also known as cumin, is warm and pungent and is generally used as a seasoning to add flavor and make food more fragrant, but fennel is warm in nature and can easily lead to fire after consumption by lactating women, which may cause ulcers or hemorrhoids and is not good for the health of lactating women. After the baby has been breastfed, it may also have symptoms of fire, so try not to eat fennel while breastfeeding. In addition, lactating women with lung heat and stomach heat should be cautious about eating it. The vegetable fennel is often eaten as a filling or in soup, with a special fragrance, but it has a certain effect of returning to the breast, affecting the secretion of female milk, and for breastfeeding women, it should not be eaten, which is not conducive to lactation. During breastfeeding, a light diet should be the main focus, intake of high-protein foods to supplement nutrition, while increasing dietary fiber intake to prevent constipation. If you want to increase breast milk, you can eat more carp, pig’s feet and other foods, and if you want to return breast milk, you can eat foods such as malt, fennel and leek.
