7. Halibut
It’s rich in vitamin D (50% of your daily value), vitamin B12 (20%) and vitamin B6 (25%), which makes it a smart choice when cooking at home or dining out. Plus, B12 (which is important for cognitive function) can only be found in animal products, so eating a lower calorie, heart-healthy choice like fish is typically your best bet for maximum health benefits.
8. Black Beans
Beans and legumes are rich in important B-vitamins, specifically the neuro-protectors folate and B6. Folate is especially important because it’s responsible for the conversion of homocysteine into the amino acid methionine, which helps regulate your liver. High levels of homocysteine have been linked with an increased risk of Alzheimer’s, meaning eating enough folate is crucial for lowering your risk.
