Cow’s Milk is for Calves

John Pierre, a nutrition and fitness expert, author, and specialist in increasing cognitive wellness in people of all ages, explains why dairy is not part of a healthy and balanced diet, especially in children. Cow’s milk contains natural and artificial hormones, as well as antibiotics, which have negative effects on human health.

John Pierre says it right, cows are mammals and therefore produce milk for their young. "... a female cow secretes milk that is intended to nurse her baby calf for about one year. This fatty hormonal secretion (containing over 60 hormones and growth factors) is designed to take her 65 pound newborn calf and turn him into a 700-pound cow in less than one year — quite a feat!

Why then do humans continue to drink something not meant for them? The answers seems to be taste, profit, convenience and tradition. These are hardly good reasons for those who want to be good stewards of their bodies and of the rest of God’s Creation.
