The Claim
Among elderly individuals aged 73 and older, a dietary pattern characterized by lignans, flavonols, and isoflavonoids from cruciferous vegetables, pulses, and leafy vegetables explains up to 77.4% of the variance in polyphenol intake and is the only pattern significantly associated with reduced dementia risk and slower cognitive decline 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.
In people aged 73 and older, a diet rich in lignans, flavonols, and isoflavonoids from cruciferous vegetables, pulses, and leafy greens accounts for 77.4% of polyphenol intake and is linked to lower dementia risk and slower cognitive decline over three years.

Eating vegetables, beans, and leafy greens delivers plant compounds that enter the brain, stop harmful buildup of sticky proteins, reduce cell damage from free radicals, and calm inflammation in brain tissue. This keeps brain cells alive and connected, preventing memory loss and dementia.
What the research says
1 studyIn older adults, eating lots of leafy greens, beans, and broccoli (which contain certain plant compounds) makes up most of their healthy plant chemicals, and those who ate more of these foods had much lower risk of dementia and slower memory loss over three years.
