As if we needed another reason to eat a whole food diet!
“A refined diet that lacks fiber impairs emotional memory in aging brains within just a few days, showing that brain function responds to food choices far faster than many people realize
The study found the biggest damage in the amygdala, the brain region that helps you connect actions with consequences and recognize danger, meaning poor diet choices weaken your brain’s ability to learn from negative experiences
Fiber-free diets sharply reduce butyrate, a compound produced by gut bacteria that protects your brain, regulates inflammation, and supports communication between your gut and brain
Researchers discovered that refined diets also slow mitochondrial activity in brain immune cells, reducing the energy required for memory formation and making older brains far less resilient to dietary stress
Restoring gut health and brain function requires removing refined foods and seed oils high in linoleic acid, stabilizing digestion, and gradually rebuilding fiber intake so gut bacteria can resume producing butyrate.” From Dr. Mercola.
