Glutamine
Glutamine is the most abundant naturally occurring, nonessential amino acid in the human body, and one of the few amino acids that can directly cross the blood–brain barrier. Humans obtain glutamine through catabolism of proteins in foods they eat. In states where tissue is being built or repaired, like growth of babies, or healing from wounds or severe illness, glutamine becomes conditionally essential.
Gynoid fat distribution
Gynoid fat is mainly composed of long-chain polyunsaturated fatty acids. It is proposed that babies which are breast-fed are more likely to have increased cognitive capabilities due to these fatty acids being present in the breast milk, as they have been suggested to aid early brain development in foetuses and newborns. The most notable fatty acids found in human breast milk are Docosahexaenoic acid and Arachidonic acid, which have been shown to play crucial roles in the healthy formation and functions of neurons.
