Your question seems to suppose the idea that the health of the brain is independent and unrelated to the of the overall health of the rest of the organism. This has historically been a common belief in western medicine but evidence to the contrary is now abundant. Studies I have read suggest the adult brain is able to generate new cells in the presence of these conditions: being required to learn something new and challenging, physical exercise, and adequate nutrition. Some of the food ingredients most mentioned in health literature supporting brain health and development are omega oils, especially DHA/EPA.
