Walnuts Named Top Nut for Brain Health, May Reduce Dementia Risk

Neurologists are pointing to walnuts as the nut most strongly linked to better brain health and a lower risk of dementia. Rich in plant-based omega-3 fatty acids, antioxidants, and fiber, walnuts help reduce inflammation, protect neurons, and support cardiovascular health—all factors tied to preserving memory and cognitive function as we age. Experts recommend including walnuts as part of a balanced diet, such as the brain-friendly MIND or Mediterranean diets, alongside other healthy habits like regular exercise, good sleep, and mental stimulation. While there’s no guaranteed way to prevent dementia, research suggests that adding a handful of walnuts to your daily routine may help keep your brain sharp well into the future.
