Will diet affect the production of breast milk in lactation?

New mothers try everything to keep breast feeding after they knowing the advantages of breast feeding. However, it has recently been found that many mothers have some misconceptions about the lactation diet.

In order to increase the number of milk, mothers are looking for milk recipes, in addition to the traditional carp soup, pig’s feet soup and so on, heard that durian, milk skin has become a popular way to increase the amount of milk.

Some mothers are wanting to have the body shape back, but also concerning that diet will affect the amount of milk. Does it will sacrifice the mother’s body while satisfying the baby’s needs? The answer is definitely not. Today we will come to know the relationship between breast milk production and mothers.

Breast milk production

After two days baby was born, breast milk production was very small, and it increased significantly from the 3rd and 4th day, gradually reaching the level of maintaining pure breast feeding. In fact, the production of breast milk is mainly determined by the baby’s needs, rather than the mother’s lactation capacity. Many mothers also know that if you want to increase the output of breast milk, it is more effective to empty the breast timely and regularly, and shorten the time between breast-feeding.

After establishing the rule of breast-feeding, the average daily output of breast-feeding mothers is 750-800ml. But the individual difference of milk production is very big, some of them are over lactating, or the mothers who feed twins or triplets can produce more than 2000 ml of milk per day. However, the output of breast milk will be significantly reduced in the later stage of lactation (more than six months after delivery), which is mainly related to the addition of complementary food.

According to the data of breastfeeding for healthy infants, the average daily output of breast milk at 6, 9 and 12 months after delivery was 769ml (335ml-1144ml), 637ml (205ml-1185ml) and 445ml (27ml-1154ml) respectively. The range depends on the number and frequency of complementary foods.

Factors that affect breast milk production

Decreased demand for breast milk is the main cause of decreased milk production. This depends on the age of the infant and the rate of weight growth, unless there is a disease that affects the metabolic needs or effective sucking capacity of the infant. In addition, the addition of milk powder and the introduction of solid food will also reduce the baby’s demand for breast milk. At this time, the mother often has incomplete emptying of the breast and the interval between breastfeeding is too long, thereby reducing the production of breast milk. What’s more, maternal smoking, stress, anxiety,fatigue, illness, and oral estrogen containing compound contraceptives will reduce breast milk production.

Does exercise affect breast milk production?

The study data shown that the influence of the mother’s diet light moderate restriction and aerobic exercise on the breast milk production was very small. In one study, 12 weeks postpartum lactating women were randomly divided into 3 groups: the first one was diet control, the second was diet control + exercise, the third was normal diet + no exercise, 11 days later, the measurement found that the weight loss of the three groups were 1.9, 1.6, 0.2kg respectively, and there was no difference in breast milk production, composition and infant weight growth. The production of human milk will be significantly reduced only when the caloric intake is severely restricted (for example, if the daily intake of calories is less than 1500 kcal, the production of human milk will be reduced by 15%).
