According to the Alzheimer’s Association, 5.4 million Americans suffer from the devastating disease. Although today there is no cure, studies show that lifestyle changes, such as changing the foods you eat, may help keep your memory sharp. More research is needed, but consider increasing or adding the following foods for a brain healthy diet.

Beans The key ingredients in beans are the healthy B-complex vitamins. One study showed that high levels of vitamins B-6 and B-12 are linked to lower levels of homocysteine, an amino acid that has been linked to Alzheimer’s disease.

Oranges Oranges and other citrus fruits have high levels of vitamin C. Some studies show vitamin C can have a protective effect on the brain and dissolve toxic plaques that are found in individuals with memory loss.

Almonds This tasty nut contains vitamin E, which promotes healthy blood flow, especially to the brain. Fish Incorporating fish into your diet increases your levels of omega-3 fatty acids. Scientists have found people with low levels of omega-3 have more brain shrinkage and poor performance on memory tests.

Spinach This leafy green is packed with more than 15 antioxidants that have been shown in studies to inhibit the formation of plaques that build up in those with Alzheimer’s disease.
