Canned light tuna is safe 2–3 times weekly, but albacore contains triple the mercury—limit to one serving per week to reduce dementia risk in aging brains.
A 2026 study linked high-quality plant-based diets including legumes to 7-12% lower Alzheimer's risk, but the link remains causally unproven.
Multiple large cohort studies report associations between berry consumption and slower cognitive decline or reduced dementia risk, yet the underlying...
Methylene blue poses severe serotonin syndrome risk with antidepressants and is not FDA-approved for dementia; unregulated supplements multiply the danger.
Multiple recent observational studies link higher fiber intake to 26–34% lower dementia risk in older adults, but causation remains unproven and robust human trials are pending.
Observational studies misled us: the apparent dementia risk of alcohol abstinence disappears when reverse causation is controlled, and genetic evidence refutes the protective effect.
Meal timing improves executive function in small studies, but direct evidence that it prevents Alzheimer's is absent; established brain-health strategies remain the priority.
Animal evidence for a fasting-mimicking diet and Alzheimer's is compelling; human proof that it prevents cognitive decline is years away.
Recent research shows high-fat dairy like cheese and cream may lower dementia risk by 13–16%, contradicting the dairy-free diet claim.
Sage extract showed promise in small trials but home-brewed tea lacks therapeutic doses; drug trials have failed, and long-term evidence remains absent.
