The sugar in mother's milk is lactose.

The sugar in mother's milk is lactose. This substance increases the absorption of calcium in the infant's intestine and improves its bone growth process. In addition, the lactose in the mother's milk lessens the infant's constipation, and thus eases its bowel movements.

Also, due to the interaction of this sugar matter with other substances, the useful microbes of the intestine further grow and multiply and with the secretion of an acid substance, create an inappropriate environment for the pathogenic microbes to grow and prevent digestive disorders. 4. Water The amount of water in mother's milk is sufficient to liquefy with appropriate density so that the infant would not need extra water.

For this reason during the first five months that the infant is breastfed only with mother's milk, it does not need water beside the milk. The amount of water in mother's milk is so much that if the infant is afflicted with diarrhea for any reason, it will be safe against lowering of body water (dehydration), which is the major incidence of diarrhea. 5.

Vitamins Mother's milk contains various kinds of vitamins dissolved in water and fat;[^3] and since this milk is fed fresh and without being heated, it contains the highest amount of vitamins, for most of these vitamins are ruined and rendered useless when heated over 60˚ C. 6. Salts and Minerals The minerals existing in mother's milk are quantitatively compatible with the infant's urinary system and kidneys.

Such salts as calcium, phosphorus, sodium, and potassium exist in mother's milk to the extent that while providing for bone growth, nervous system, and other tissues and satisfying the baby's natural needs, they do not impair the kidneys' discharge of urine. The minerals existing in mother's milk are of such high quality that they satisfy the body's structural needs through better absorption.

In any case, the researches indicate that feeding the babies with human milk would reduce the incidence or intensity of diarrhea, the infection of lower respiratory system, and the urinary system.
