Introduction
The foods we enjoy each day fuel our brains. They also may affect how we age. Simple food choices can help protect memory over time. This page shares nutrition tips to help you and your loved ones choose foods that support your brain and body.
Scientists have found that a healthier diet is associated with a lower risk of Alzheimer’s disease and related dementias (ADRD) and a slower pace of aging. They are still learning how food affects the brain, but we know a few things. Whole foods can help the brain stay healthy and eating fewer packaged and fast foods may help protect memory.
Did you know?
The Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) Diet focuses on brain-healthy foods. When combined with exercise, time with others and regular doctor visits, it may help protect memory in older adults.
Why Food and Diet Matter
- The brain uses about 20% of the body’s energy and needs steady fuel from food.
- Healthy foods help the brain work well. They can reduce swelling and harmful irritation in the body and help make blood flow more easily.
- Eating more vegetables, whole grains, healthy fats and lean meats may help lower the risk of ADRD. See the chart below for some healthy examples.

Tips to Make Healthy Eating Easier
Start with one small change, such as adding one food from the brain-healthy list above.
Drink water every few hours, even if you don’t feel thirsty.
Prep meals ahead of time. Try canned/frozen veggies to save time.
Keep healthy snacks where you can see them.
Eat with others when you can. Sharing meals can help your brain release endorphins, which are chemicals that help you feel good.
