Lipid Requirements during Pregnancy and Lactation
Nutrition concepts have been dominated by considerations of protein and body growth. Lessons from comparative studies tell us that the difference between man and other animals is not concerned with body growth but with the specialisation of the brain. For example, the rhinocerus at the age of four years has a body weight of about one ton yet its brain only weighs a few hundred grams. By contrast the body size of the four year old human child is small yet its brain weighs about 1.5 kg and has virtually completed all its growth. Hence it seems to us that different biological principles may be involved in body growth on the one hand and brain growth on the other. In this context it is interesting that whilst protein is quantitatively the most important component of muscle and minerals of bone, lipids are the more important in the brain and nervous system.
