Sedaia [141]

Answer:

the protective effect breast milk has against obesity decreases if a mother continues nursing beyond one year.

Explanation:

A breast milk can be defined as the milk produced by a woman after delivering a child (childbirth), especially as a source of food and essential nutrients.

The advantages of the breast milk provided by a mother to her child (baby) include the following;

I. It prevents illness and infection because it contains antibodies.

II. It contains colostrum that serves as the first form of immunization for infants or babies.

III. Infants that are given birth to prematurely but who are well breast-fed usually perform better on IQ tests and have overall better cognitive performance.

All of the aforementioned statements are advantages of breast milk except that, the protective effect breast milk has against obesity decreases if a mother continues nursing beyond one year.

This simply means that, when a nursing mother continues to breastfeed her baby for over a year, it reduces its protective effect against obesity.
