MILK

摘要

Milk is a richly nutritious mixture of water, proteins, minerals, vitamins, sugars, saturated fat and cholesterol. All mammals make it, but humans are the only ones to drink it beyond their early years. Should we? Breast milk - or synthetic versions of it - provides the "perfect balance of nutrients" for babies in their first year, says Andy Bernstein, a paediatrician at Northwestern University in Evanston, Illinois. After that, full-fat cow's milk is recommended as a good source of fat for brain development, dropping to 1 or 2 per cent fat milk from age 2.
