The Claim
A dietary polyphenol pattern rich in lignans, flavonols, and isoflavonoids is associated with a reduced risk of dementia after adjustment for age, sex, education, physical activity, smoking, alcohol consumption, hypertension, diabetes, stroke history, coronary disease, and baseline mild cognitive impairment.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who consume a diet high in lignans, flavonols, and isoflavonoids have a lower incidence of dementia compared to those who do not, even after accounting for age, sex, education, lifestyle factors, and pre-existing health conditions.
See the scientific wording
The association between a polyphenol pattern rich in lignans, flavonols, and isoflavonoids and reduced dementia risk persists after adjusting for age, sex, education, physical activity, smoking, alcohol consumption, hypertension, diabetes, stroke history, coronary disease, and baseline mild cognitive impairment.
Eating foods rich in certain plant compounds reduces harmful buildup in the brain, stops brain cells from getting damaged by free radicals and inflammation, and prevents toxic protein clumps from forming, which keeps memory and thinking skills strong.
What the research says
1 studyPeople who ate more leafy greens, beans, and cruciferous vegetables had a much lower risk of developing dementia, even when scientists accounted for other health habits and conditions like smoking, diabetes, and exercise.
