The Claim
In older adults with preclinical Alzheimer’s disease and amyloid positivity, higher intake of fruit and grapes is associated with reduced rates of cognitive decline, including among individuals carrying the APOE ε4 allele.
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.
Older adults with early signs of Alzheimer’s and amyloid buildup who eat more fruit and grapes show slower cognitive decline, even if they carry the APOE ε4 gene variant.
See the scientific wording
In older adults with preclinical Alzheimer’s disease and amyloid positivity, higher fruit and grape intake is associated with reduced cognitive decline even among APOE ε4 carriers, suggesting that dietary patterns may partially offset genetic risk for Alzheimer’s progression.
Compounds from fruits and grapes enter the brain and stop harmful proteins from clumping together and forming tangles, which protects nerve cells from damage and keeps memory and thinking skills from worsening.
What the research says
1 studyEven for older people who have a gene that makes them more likely to get Alzheimer’s, eating more fruits and grapes every day was linked to slower memory loss and less buildup of harmful brain proteins.
