This high-fat eating plan may offer a powerful way to shield the aging brain

Article excerpt

A new study suggests that a high-fat diet may protect the aging brain by strengthening the gut-brain communication pathway. Researchers found that dietary fats trigger biochemical signals traveling between the digestive system and brain, potentially slowing neurodegenerative diseases. The discovery highlights how the gut and brain constantly exchange molecular messages that influence digestion, mood, and neurological health. Scientists say understanding this two-way conversation could reshape how doctors approach brain aging and disease prevention through diet.
