Alcohol Raises Dementia Risk at Every Level of Drinking

A study found that alcohol raises dementia risk at every level of drinking, overturning decades of claims that moderate use protects your brain Even light drinking damages neurons, disrupts mitochondrial energy production, and accelerates brain aging, showing there is no safe dose for cognitive health Genetic data revealed that for every measurable increase in alcohol consumption, dementia risk rose by about 15%, with the danger extending across all age and ancestry groups Alcohol and linoleic acid (LA) from seed oils follow the same toxic pathway in your liver, creating harmful aldehydes that cause mitochondrial damage and fatty liver disease, both of which impair brain function Reducing or eliminating alcohol and cutting seed oils to under 5 grams per day — ideally 2 grams — support liver recovery, restore mitochondrial function, and protect long-term brain health
