Environmental Contaminants Reduce in Breast Milk During Lactation

Breast milk is the best food for the infants. It is rich in all the nutrients required for the growth and development of the baby. At the same time, breast milk also contains measurable concentrations of the harmful chemicals from manufacturing products and industry. However, the recent study conducted at the Norwegian Institute of Public Health says that the levels of environmental contaminants in the breast milk drops by 15 to 94% after a year of nursing the child. These contaminants enter the mother’s body through food and excreted partly in the breast milk.

The study was conducted on Norwegian women as they are known to breast-feed for a long period of time. The researchers tried to find out how the contaminants of the breast milk change during lactation period for each participant. Upon observation, it was noticed that nearly all the compounds present in milk decrease over a period. They are reduced by 15% to 94% during one year of lactation.

The findings should be considered when studying the benefits of breast milk. However, the environmental contaminant levels in the blood and breast milk have declined considerably in the recent decade. The industry and the authorities have succeeded in reducing these contaminants in the environment. This has decreased the amount of chemicals ingested by the population.
