Studies of primitive man show their brain growth depended on the amount of omega 3-DHA fatty acids in their food. The evolutionary record demonstrates that the ancestors of modern humans that migrated from Africa, between 40,000 to 100,000 years ago, lived along lakes and rivers. They ate fish and shellfish that provided large amounts of omega-3 DHA.
Omega-3 DHA is believed to be an important factor in the growth of the size and complexity of their brains. Compared to extinct Neanderthals and other hominids, the increased rate of our homosapien ancestor’s brain growth resulted in survival advantages and complex cultural behaviors such as tool making and language.
Docosahexaenoic acid, otherwise known as DHA, is one of the two omega-3 fatty acids in fish or shellfish. DHA is found within the membranes of all cells in your body with the greatest concentration being within neurons of your brain.
To understand the importance of DHA in brain development, consider that half of a woman’s entire DHA supply is transferred to her baby during the third trimester of pregnancy. This transfer gives her baby a 1 year supply of DHA which is what her baby needs for proper brain development.
Our brain’s need for DHA lasts a lifetime. Unfortunately, the average American diet contains inadequate amounts of DHA. The 2010 Dietary Guidelines for Americans recommended two servings of seafood per week (4 oz. each) to provide adequate intakes of DHA as well as EPA, another omega-3 fatty acid. But most of the meat we regularly consume (beef, pork, fish, and chicken) are grain fed and contain almost no DHA at all.
The food we feed an animal determines the DHA we will ultimately feed ourselves. Meat and eggs from pasture-fed or wild animals contains significantly higher proportions of DHA and EPA than meat from domesticated animals, even if those domesticated animals are “free-range” or organically-reared.
Insufficient DHA in our diets is now being linked with a variety of neurological illnesses such as depression, bipolar disorder, PTSD, epilepsy, Alzheimer’s and Parkinson’s Disease. There is also strong evidence of the benefits of DHA supplementation in the prevention of primary and secondary heart disease.
Look at the quality of your food and when possible add wild fish or grass-fed beef to your menu. If cost is a factor, be sure everyone in the household is supplementing with a high-quality fish-based omega-3 supplements.
Fish oil is forever because DHA is your brain’s favorite food. You want to eat DHA like a homosapien so that your brain does not function like a Neanderthal.
