The Claim

Higher total vegetable consumption (>200 g/d) is associated with lower amyloid PET burden and slower progression of amyloid accumulation over two years in older adults with preclinical Alzheimer’s disease and amyloid positivity.

In plain English

Older adults with early Alzheimer’s disease and confirmed amyloid buildup who consume more than 200 grams of vegetables per day have lower levels of amyloid in the brain and a slower rate of amyloid accumulation over two years.

See the scientific wording

Higher total vegetable consumption (>200 g/d) is associated with lower amyloid PET burden and slower progression of amyloid accumulation over two years in older adults with preclinical Alzheimer’s disease and amyloid positivity, suggesting a potential role for overall vegetable intake in modulating amyloid pathology.

Why this might work

Eating more vegetables delivers compounds called flavonoids and folate into the bloodstream. These compounds enter the brain and stop amyloid proteins from clumping together. They also block enzymes that over-activate tau proteins, preventing them from forming tangles. This reduces brain damage and slows the buildup of harmful plaques.

    People over 50 with early signs of Alzheimer’s who ate more than 200 grams of vegetables a day had less of the harmful brain protein (amyloid) buildup, according to brain scans. Eating more veggies was linked to slower worsening of this protein over time.
