Which of the following is NOT a nutritional factor linked to Alzheimer's disease prevention?

Folate
Vitamins B12, C, and E
High sugar intake
Dark colored fruits and vegetables

The correct answer is: High sugar intake

High sugar intake is linked to various health issues but is not considered a nutritional factor that contributes positively to Alzheimer's disease prevention. Instead, research indicates that it may have detrimental effects on brain health, potentially increasing the risk of cognitive decline and Alzheimer's. In contrast, folate, vitamins B12, C, and E, as well as the consumption of dark-colored fruits and vegetables, are often highlighted for their positive roles in brain health. Folate supports cognitive function and can help reduce the risk of dementia. Vitamins B12, C, and E are important for various neurological functions and have antioxidant properties that protect the brain from oxidative stress. Dark-colored fruits and vegetables are rich in antioxidants and other nutrients that may support brain health, potentially reducing the risk of cognitive decline. Therefore, while the other options are associated with positive outcomes regarding the prevention of Alzheimer's disease, high sugar intake does not bear a beneficial link in this context.
