Neurologists Urge Limiting 4 Foods Linked to Brain Damage

3 articles · Updated · RBC-Ukraine · May 14

Four products — protein powder, sugary carbonated drinks, beer and French fries — were flagged by neurologists as foods to avoid or sharply limit to protect memory, concentration and long-term brain function.
Sugary sodas drew the strongest warning: neurologist Shaheen Lakhan said high sugar can damage blood vessels feeding the brain, raising risks of inflammation, sleep disruption, premature dementia and stroke.
Protein powder was cited for artificial sweeteners that may disrupt the gut microbiome and for possible heavy-metal contamination in poorly made products, both of which could affect the nervous system over time.
Beer and French fries were highlighted for repeated exposure rather than occasional intake — alcohol as a neurotoxin that impairs memory and learning, and fatty foods for harming vascular health and hippocampal neurons tied to learning and memory.
The doctors' advice centers on cumulative risk: frequent consumption may quietly erode brain health even when short-term effects are not obvious.

Beyond avoiding certain foods, what can we eat to actively build a brain that resists cognitive decline and aging?

With California's new testing law, how can you know if your 'healthy' protein powder is secretly harming your brain?
