Increasing the energy supply (ATP) in damaged spinal cord nerves promotes regeneration and regrowth of axons (nerve fibers); damaged axons in spinal cord injuries impair ATP production.

The community important factors that lowered life expectancy were more fast food restaurants, higher population density, and more jobs in mining, quarrying, and oil/gas extraction.

People who ate a low-carb diet (no sugar, grains, rice, or starchy vegetables) for one week had a more stable brain network, likely due to the brain using ketones rather than glucose for fuel.

Excess visceral abdominal fat causes inflammatory proteins (interleukin-1 beta) to cross the blood-brain barrier, leading to over-activated microglia (which are usually protective) and impaired cognition.
