While it is a well-established fact that breast milk is the best form of nutrition for infants, have you ever wondered what does breast milk tastes like? Many women often ponder the question to determine if their baby is getting healthy breast milk. It is also believed that changes in breast milk’s taste may affect the breastfeeding baby’s appetite.
This post carries answers to your questions regarding breast milk’s taste, factors affecting it, and whether it is okay for you and your partner to taste breast milk.
What Does Breast Milk Taste Like?
Human breast milk tastes sweet and creamy and a lot similar to cow’s milk. This interpretation, however, varies from person-to-person. Some people find breast milk heavily sweetened, almost like honey or sugar water, while others recall it being sweet-salty.
Whatever the perceived taste, the vital point to note is that breast milk does have a peculiar taste. But if that’s the case, you may wonder how does breast milk gets its taste?
What Gives Breast Milk Its Taste?
Human milk’s flavor relies on its nutritional composition, greatly influenced by what you eat during the lactation period. Evidence suggests that a mother eating a well-balanced diet containing foods from different food groups exposes her young one to varying flavors from a young age. It could impact your baby’s food choices later in life since they would be more likely to accept foods with a familiar taste (1) (2).
Factors That Affect Breast Milk Taste
Below are some of the significant factors that could affect the flavor of breast milk.
- Food: A baby may get their first taste of food flavors in the mother’s womb since the mother’s diet could affect the taste of the amniotic fluid (3). Babies get reintroduced to these tastes during breastfeeding when the mother eats the same food and drinks. In the beginning, the baby might not respond to these flavors amicably. But gradually, they develop a tolerance to it. Nevertheless, they may dislike a sudden change in breast milk’s flavor due to certain foods in the maternal diet. Experts note that strongly flavored foods, such as garlic and chili, may change the breast milk’s taste and smell (4) (5).
- Hormones: Hormonal changes postpartum are as obvious as they are during pregnancy. They can occur when your menstrual cycle returns. Hormonal changes could alter breast milk’s flavor temporarily. For instance, around ovulation, the sodium and chloride in breast milk increase, and the amount of lactose and potassium reduce, making the milk saltier (6).
- Alcohol: Consuming alcohol when breastfeeding exposes your baby to health risks as the alcohol passes to the baby through breast milk. Besides, it alters breast milk’s flavor and might cause sensitive babies to stop feeding temporarily (7).
- Smoking: Research shows that smoking when breastfeeding could affect breast milk’s taste (8). The alteration in the taste might affect sensitive babies, impacting their breast milk intake. Experts recommend quitting smoking during the lactation period.
- Medications: Several medicines might affect breast milk’s taste and smell, affecting the baby’s milk intake. Discuss with your doctor in detail the effects of any medication on your breast milk’s taste and baby’s health in general.
- Breast infection: Breastfeeding mothers often face breastfeeding problems, such as breast inflammation due to mastitis, which is a breast infection. Research notes that breast inflammation due to infections tends to make the breast milk salty (9).
- Breast milk storage: Expressed breast milk stored appropriately is safe for consumption. However, incorrectly stored breast milk could taste metallic or fishy (10). These changes indicate the milk has gone rancid and is unfit for consumption. Breast milk’s taste could also change when frozen. However, it is a normal change due to lipase, an enzyme in breast milk that breaks down the milk fat into fatty acids.
Can Adults Consume Breast Milk?
An adult may try their or their partner’s expressed breast milk. You must avoid trying or letting your partner try breast milk if you can transmit any infection through it. Some people wish to try someone else’s breast milk, but doing so can be potentially dangerous since it could cause the transmission of dangerous pathogens, including HIV and hepatitis viruses.
Frequently Asked Questions
1. How does breast milk smell?
Similar to taste, the smell of your breast milk may also depend on your diet or the presence of excess lipase and give out a sour, soapy, or fishy odor (10).
2. Does breast milk get sour in the breast?
Breast milk may taste sour due to increased chemical oxidation or lipase activity in the body. But it does not imply that the milk has gotten bad inside the breast. Despite the taste or the smell, milk, drunk straight from the breast, is completely safe for the baby (10) (11).
3. What if the baby drinks bad breast milk?
If you accidentally give your baby stale stored breast milk, they may vomit it. However, you must consult your doctor if you see more severe reactions such as fever or diarrhea.
What does breast milk taste like is a common question that might occur to many? However, it should be noted that the interpretation of the taste varies from one person to another. Several factors can affect the taste of breastmilk and alter its composition, such as food, health, hormones, or any form of sickness. Therefore, it is advised that nursing mothers should have nutritious food and take proper care of themselves to ensure that their baby is getting the right amount of nutrients.
