Sorry, soda drinkers. Neurologist Dr. Shaheen Lakhan says your favorite bubbly beverage is just flat-out bad for your brain. “Soda is one of the worst foods for brain health due to the high concentration of simple sugars, which damage the blood vessels supplying the brain,” he said. “Over time, this starves the brain from the very fuels it needs to function, leading to premature dementia and strokes. Acutely, sugar also causes brain inflammation, irritability, poor mood, and sleep disturbances.”
Plus, the constant highs and lows (the proverbial sugar “rush” and “crash”) can also cause a state of addiction with cravings and withdrawals — and diet soda is no better. “Even diet or zero versions of soda have negative effects, as the calorie-free additives stress out the brain and trick it into consuming more calories and craving real sugar,” he said.
