A Singaporean mother placed her freshly expressed breast milk under a microscope at 1,000x magnification and discovered many moving particles—it was alive.

　　It turns out that breast milk contains substances such as fat globules,lactoferrin,and immune cells,all of which remain active in the milk.When observed under a microscope,these components can be seen moving around.It is these active elements in breast milk that provide essential nutrients for infant growth and contribute to a baby's health in ways that formula milk cannot easily replicate.

　　When comparing formula milk and breast milk under a microscope,the differences are striking.

　　Formula milk contains no cells,while breast milk is rich in white blood cells and fat globules.White blood cells help boost a baby's immunity,and fat globules support the rapid development of an infant's eyes and brain.

　　Indeed,breast milk appears to be one of the best foods nature has evolved to offer newborn babies.
