The Claim
A 1-unit increase in intake of a dietary pattern high in lignans, flavonols, and isoflavonoids is associated with a 0.9% reduction in the annual rate of global cognitive decline in elderly individuals aged 73 and older, as measured by standardized neuropsychological testing over three years.
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.
Elderly individuals aged 73 and older who consume a diet higher in lignans, flavonols, and isoflavonoids show a 0.9% slower rate of cognitive decline per year compared to those with lower intake, as measured by standardized neuropsychological tests over three years.

Eating foods rich in these plant compounds reduces harmful buildup of toxic proteins in the brain, calms inflammation, and neutralizes damaging molecules, which keeps brain cells and their connections working longer.
What the research says
1 studyPeople who ate more of foods like broccoli, beans, and spinach had slightly slower memory and thinking decline over three years — exactly what the claim says.
