Genetic Adaptation Of Fat Metabolism Key To Development Of Human Brain

Now it is clear why fat people have problems thinking.

About 300 000 years ago humans adapted genetically to be able to produce larger amounts of Omega-3 and Omega-6 fatty acids. This adaptation may have been crucial to the development of the unique brain capacity in modern humans. In today's life situation, this genetic adaptation contributes instead to a higher risk of developing disorders like cardiovascular disease. The human nervous system and brain contain large amounts of polyunsaturated fatty acids, and these are essential for the development and function of the brain. These Omega-3 and Omega-6 fatty acids occur in high quantities in just a few foods, such as fat fish. Our bodies can also produces these important fatty acids themselves from certain vegetable oils.

They do not process fat properly and add it to their bodies instead of metabolizing it properly for use by their brains.

Not.

If they could have used their brains properly to begin with, they would not have gotten fat in the first place.
