Q Are there foods that are good for preventing dementia? How should I change my usual diet?
A The Mediterranean diet (fish, olive oil, vegetables, whole grains, nuts) has the most research showing it lowers dementia risk. The key is to cut down on red meat, processed meat, and sugar while increasing colorful vegetables and oily fish.
Detailed Answer
The Mediterranean diet and the MIND diet have clinical evidence for lowering Alzheimer's risk. Omega-3 fatty acids (mackerel, salmon, perilla oil) protect brain nerve cell membranes, and antioxidant foods such as blueberries and spinach reduce oxidative damage to the brain. On the other hand, ultra-processed foods, saturated fat, and excessive sugar harm brain blood vessels and insulin sensitivity, and are linked to cognitive decline.
