Why children grow slowly

Researchers at Northwestern University (Il) say they've solved the mystery: why human children grow slower than other mammals — most of his energy the body uses for the expansion of the brain.

A brain scan shows the brain of a child of five is an "energy monster" that uses twice the glucose, grown adult. Anthropologist Christopher Kuzawa says: "the Results show that our body can't afford to grow faster in childhood, because a huge amount of resources required for the nutrition and development of the human brain".
This study was the first that consolidated the existing PET and MRI of the brain to measure glucose uptake and brain volume and showed that age, when the brain consumes the most resources, are also a period in a person's life, when body growth is slowest.
