Brain Building

Today in the United States, 1 in 6 children suffers from a disability that affects their behavior, memory, or ability to learn. More than $80 billion dollars are spent each year in the U.S. to treat neurodevelopmental disorders. Diagnoses of Attention Deficit Hyperactivity Disorder (ADHD ) alone up are up 250% since 19901. How much of a role does modern food play in this increase?

Children's brains are built differently depending on what they are fed when they are rapidly growing. Healthy brains are about 60% structural fat (not like the flabby fat found elsewhere in the body). As the brain grows, it selects building blocks from among the fatty acids available in what the child eats. The most prevalent structural fat in the brain is DHA (docosahexaenoic acid), one of the omega 3  fatty acids. DHA is also a major structural component of the retina of the eye. A large number of studies have suggested that low DHA levels are associated with problems with intelligence, vision, and behavior2.

DHA is the most prevalent long chain fatty acid in human breast milk , which suggests that it's intended for babies to consume a lot of it. Studies have shown that babies who have not gotten DHA in their diets have significantly less of it in their brains than those who have3.

My point (at the moment) is not about the superiority of breast milk, but that growing children quite literally are what they eat . When you think about this, you begin to feel differently about “cheap” food.
