The Importance of DHA for Brain Health
DHA, or docosahexaenoic acid, is an essential fatty acid that is crucial for brain health. It is the major structural component of the brain's cell membranes and is responsible for stimulating gene expression. DHA is primarily found in the marine food web, and access to this food web during human evolution played a key role in the expansion of the human brain.
The Role of DHA in Brain Evolution
The human brain has the largest brain relative to body size of any animal. This is due, in part, to the consistent consumption of seafood during early human evolution. DHA is essential for the growth and development of the brain, and without it, humans would not have been able to develop the large brains that we have today.
As animals get bigger, their brains get relatively smaller. Homo sapiens are the only exception to this trend. This is likely due to the fact that humans had access to a source of DHA, iodine, and other brain-building nutrients found in the sea.
The Importance of DHA During Pregnancy
The brain is formed largely before birth, with about 70% of brain cells being produced during pregnancy. Therefore, it is crucial for expecting mothers to consume adequate amounts of DHA, both before and during pregnancy.
Studies have shown that children of mothers who ate the most seafood during pregnancy had the best verbal and motor function at eight years of age. Conversely, children of mothers who followed the FDA's recommendation to limit seafood consumption during pregnancy had the worst outcomes for cognitive and mental health development.
DHA Supplementation
While fish oil supplements can provide some DHA, they are not as effective as eating seafood. This is because fish oil is a triglyceride, while the structural fat used for building the brain is a phosphoglyceride. Seafood contains DHA in the phosphoglyceride form, which is more readily absorbed and utilized by the body.
The Quantum Properties of DHA
DHA has unique quantum properties that allow it to convert photons into electricity. This is possible because of the way DHA molecules are arranged in the cell membrane.
DHA molecules can act as semiconductors, meaning that they can conduct electricity under certain conditions. When an electron is removed from a DHA molecule, it creates a positive hole. Electrons from other DHA molecules can then tunnel through the membrane to fill this hole. This process is highly precise, as only electrons with the exact same quantum mechanical properties as the electron that was removed can tunnel through.
The quantum properties of DHA are essential for the precise signaling that occurs in the brain. The brain cannot function properly if signals are not transmitted accurately, and DHA plays a key role in ensuring that this happens.
The Future of DHA and Brain Health
The global population is growing, and there is currently not enough DHA to go around. This is a serious problem, as DHA deficiency can lead to a number of health problems, including cognitive decline, mental health issues, and vision problems.
To address this issue, we need to start farming the oceans. The Japanese have already developed successful marine farming techniques that amplify the food web and produce more seafood. We need to follow their lead and develop sustainable marine farming practices that can provide the world with the DHA it needs.
In addition to farming the oceans, we need to educate people about the importance of DHA for brain health. Governments need to start considering the importance of the brain in terms of their food and agricultural policies. We need to move away from a food system that is focused on quantity over quality and start producing food that is nutrient-rich and brain-boosting.
