DHA as a Brain Food
Different species provide different types of fat in their milk, fine-tuned to the needs of that particular animal. For example, mother cows provide milk that is high in saturated fats and low in brain-building fats, such as DHA. This helps their calves grow rapidly, though it may not do much for their brains. In adult cows, the brain is small compared with the body. Cows don't have to do a lot of thinking to survive. In human infants, the brain grows faster than the body. Highly developed brains are important to human beings, so human milk is low in body-building saturated fats and rich in brain-building fats, such as the fatty acid DHA (docosahexaenoic acid), an omega 3 fatty acid.
DHA is the primary structural component of brain tissue, so it stands to reason that a deficiency of DHA in the diet could translate into a deficiency in brain function. In fact, research is increasingly recognizing the possibility that DHA has a crucial influence on neurotransmitters in the brain, helping brain cells better communicate with each other. Asian cultures have long appreciated the brain-building effects of DHA. In Japan, DHA is considered such an important "health food" that it is used as a nutritional supplement to enrich some foods, and students frequently take DHA pills before examinations.
Just how important is DHA for brain development? Consider these research findings:
---Infants who have low amounts of DHA in their diet have reduced brain development and diminished visual acuity.
---The increased intelligence and academic performance of breastfed compared with formula- fed infants has been attributed in part to the increased DHA content of human milk.
---Cultures whose diet is high in omega 3 fatty acids (such as the Eskimos who eat a lot of fish) have a lower incidence of degenerative diseases of the central nervous system, such as multiple sclerosis.
Experimental animals whose diets are low in DHA have been found to have smaller brains and delayed central nervous system development.
Some children with poor school performance because of ADD, have been shown to have insufficient essential fatty acids in their diet.
