Your nervous system controls things like heart rate, digestion, memory, and your stress response. While food can’t treat or cure nervous system conditions, certain nutrients help your nerves communicate clearly, support steady energy, and help your brain and body respond to stress.

Salmon is one of the best sources of omega-3 fatty acids, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fats are important parts of nerve cell membranes and have been linked to the brain’s ability to adapt and change over time.
Omega-3s also help lower inflammation in the body and brain. Ongoing inflammation may damage nerve cells, so getting enough of these fats is crucial.
Salmon is also a decent source of vitamin D, which supports brain and nerve function.

Spinach provides nutrients that help keep your nervous system working properly, including:
- Folate: Along with a number of other micronutrients, folate helps your body make neurotransmitters like serotonin or dopamine. Neurotransmitters are chemical messengers that cells in the nervous system and brain use to communicate with each other.
- Magnesium: This mineral plays a role in nerve signaling, regulates how your muscles contract, and helps calm the nerve cells. Because of these and other benefits, magnesium may help limit the body’s stress response.
Together, these nutrients make spinach a simple way to support steady nerve function as part of a balanced diet.

Yogurt contains bacteria that may encourage a healthy gut microbiome, or the collection of microorganisms that live in your gastrointestinal tract. A healthy gut is linked to nervous system health via a communication system called the gut-brain axis.
Experts are still learning more, but there’s evidence that gut health issues are often linked to neurological conditions later in life, as well as mental health issues like anxiety or depression.
On the other hand, in one study, older adults who reported eating yogurt or dairy daily tended to score slightly higher on a standard cognitive test than those who didn’t.
This doesn’t prove that yogurt or other gut-friendly foods caused the difference; however, maintaining a healthy gut could be one way to protect your brain and nervous system health.

Pumpkin seeds are incredibly nutritious, rich in compounds that can help support the nervous system:
- Magnesium: It helps nerves send signals efficiently and supports muscle relaxation.
- Zinc: This mineral is involved in immune health and maintaining proper brain function.
- Healthy fats: Unsaturated fats help maintain the structure of cell membranes—including those in nerve cells.

Oats contain B vitamins, which play an important role in keeping your nervous system healthy. Vitamins B1, B6, and B12 help your nerves produce energy, protect them from damage, and help create neurotransmitters.
Additionally, oats are a rich source of fiber, which could help support your gut health. Some research suggests a healthier gut could protect your cognitive health, strengthen the gut-brain connection, and help regulate neurotransmitters.

Lentils are a good source of nutrients that support nervous system function, including:
- Plant-based protein: Amino acids, the building blocks of protein, also help your body make neurotransmitters like serotonin, which influences mood and behavior.
- Iron: This mineral is crucial for carrying oxygen to your brain and nerves, and is also involved in the creation of neurotransmitters so they can work efficiently.
- Magnesium: A cup of cooked lentils provides 71 milligrams of magnesium (17% of the Daily Value), helping support steady nerve and muscle function.

Blueberries are best known for their antioxidants—these compounds help fight oxidative stress, a type of damage that can build up in cells over time.
Because the brain uses a lot of energy, it’s especially sensitive to oxidative stress. That means adding more antioxidants to your diet could help protect against oxidative stress and, in turn, support nervous system health.
Specifically, research suggests that anthocyanins—antioxidants in blueberries responsible for their deep color—may be able to support cognitive health as you age, as well as limit or prevent conditions such as anxiety, depression, and Parkinson’s disease.

Dark chocolate contains multiple compounds that may support nervous system health.
Plant compounds in dark chocolate called flavonoids act as antioxidants and reduce inflammation, which may help protect against neurodegenerative diseases such as Alzheimer’s. This sweet treat is also a good source of magnesium, which helps support proper nerve signaling and muscle relaxation.
In addition, dark chocolate contains small amounts of caffeine, which stimulates the central nervous system and may help protect cognition as you age. However, caffeine can also lead to anxiety and other side effects, so be mindful of timing and how much you’re eating.
Instead of focusing on a single food, supporting your nervous system works best when you commit to healthy eating patterns overall. That means:
- Eating regular, balanced meals to support stable blood sugar
- Including protein, fiber, carbohydrates, and unsaturated fats in your meals
- Prioritizing foods high in B vitamins, magnesium, and omega-3s
- Staying hydrated
Nutrition works best alongside other habits that support your nervous system, including getting adequate sleep, exercising, and managing stress.
