6 Healthy Foods That Support Your Brain

From strengthening your focus to lowering your risk for dementia, some foods are potent brain defenders. By loading your plate with these six foods, you’ll ensure your mind remains sharp and healthy—now, and for many years to come. 

Fatty Fish

Fish like salmon, herring, and sardines are loaded with omega-3 fatty acids, which support brain functions like memory and thinking. More research shows eating fish loaded with omega 3s can lower your risk for Alzheimer’s disease by 36% or more. Taking omega-3 fish oil supplements may be similarly beneficial for brain health.

Green Leafy Vegetables

Green Leafy Vegetables

Green leafy vegetables like spinach, kale, and mustard greens are packed with vitamin K, which may slow down age-related cognitive decline. One study found older adults who ate lots of leafy greens tended to have the cognitive sharpness and ability of someone 11 years younger.

Olive Oil

Apart from its healthful omega-3 content, olive oil is also a good source of antioxidants compounds that appear to strengthen learning and memory. These healthy compounds may also fight inflammation in the brain and body, which lowers your risk for brain diseases.


Much like olive oil, blueberries contain a potent antioxidant compound that supports a strong memory, and may also help defend your brain from dementia. More research suggests both blueberries and strawberries may improve thinking clarity and mental sharpness. 

Dark Chocolate

Cocoa and chocolate contain flavanols—healthy compounds that may support focus, memory, and problem solving. Flavanols also may improve blood flow and prevent blood clots, which not only protects your brain but also safeguards your heart. 


Whether you buy this herb whole or mixed into curry powder, turmeric is a powerful antioxidant that appears to clear away dementia-causing proteins in the brain. More research hints that turmeric may improve memory and thinking ability. 

Incorporate all of these foods into your weekly diet, and there’s ample evidence you’ll sharpen your mind while protecting your brain from disease.
