After a concussion, you may find yourself dealing with headaches, fatigue, dizziness, nausea, or difficulty concentrating. You might be looking for ways to help your brain recover, including changing what you eat.
Nutrition is one part of concussion recovery, but it isn't the whole picture. You can eat well, choose nutritious foods, and do everything you can to support your brain—and still struggle with headaches, dizziness, fatigue, or exercise intolerance.
If you've been dealing with symptoms for weeks or months, you probably don't just want to know what to eat. You want to get back to exercising, working, socializing, and feeling like yourself again.
The challenge is knowing what else to address when eating well and waiting for symptoms to improve haven't been enough.
Anti-Inflammatory Foods for Concussion Recovery
A concussion can trigger changes in the brain’s metabolism, and researchers are investigating whether nutrition can support recovery after injury. A systematic review of nutritional interventions after mild traumatic brain injury found promising results for some nutritional approaches, including omega-3 fatty acids, but the evidence is still limited and does not establish one specific diet as the best approach for concussion recovery.
One practical starting point is to build your diet around whole, nutrient-dense foods rather than relying heavily on highly processed foods.
You don’t need to follow a complicated diet or eliminate entire food groups to get started. A balanced eating pattern that includes protein, healthy fats, fruits, vegetables, and other nutrient-rich foods can help you meet your nutritional needs during recovery.
Some people explore specialized diets, such as a ketogenic diet, when researching concussion recovery. However, these approaches are not necessary for everyone, and there is not enough evidence to recommend one specific diet for all people recovering from a concussion.
The goal is to provide your body with consistent, adequate nutrition—not to find one perfect food or diet that will fix your symptoms.
What to Eat After a Concussion
Certain foods provide nutrients that are important for normal brain function and overall health. Here are some practical options to include in your diet.
1. Oily Fish Rich in Omega-3 Fatty Acids
Fatty fish such as salmon, sardines, trout, and mackerel contain omega-3 fatty acids, including DHA and EPA.
DHA is an important component of brain cell membranes, and omega-3 fatty acids are being studied for their potential role in recovery after traumatic brain injury. A systematic review of nutritional supplements for concussion identified omega-3 fatty acids as one of the most frequently studied interventions, but concluded that the available evidence is not strong enough to support routine use of supplements as a concussion treatment. Eating omega-3-rich foods can still be part of a balanced diet, although research has not established that eating these foods directly speeds concussion recovery.
How to include them: Try adding salmon or another oily fish to your meals a couple of times per week, if you enjoy fish and it fits your dietary needs.
2. Chia Seeds and Other Sources of Omega-3s
Chia seeds provide plant-based omega-3 fatty acids, along with fiber and other nutrients.
Other sources include ground flaxseeds and walnuts. Plant-based omega-3s differ from the DHA and EPA found in fish, but they can still be part of a nutritious diet.
How to include them: Add chia seeds or ground flaxseeds to oatmeal, yogurt, or smoothies. Walnuts also make an easy snack.
3. Avocados and Healthy Fats
Avocados contain monounsaturated fats, fiber, and vitamin E. These nutrients contribute to a balanced diet and support normal bodily functions.
Rather than focusing on avoiding all fats, consider the types of fats you eat and the overall quality of your diet. Unsaturated fats from foods such as avocados, nuts, seeds, and olive oil can be useful alternatives to some highly processed sources of fat.
How to include them: Add avocado to eggs, salads, sandwiches, or grain bowls, or use olive oil in cooking.
4. Cacao and Dark Chocolate
Cacao contains flavanols and other plant compounds that have been studied for their potential effects on health. However, evidence that cacao or dark chocolate improves concussion recovery specifically is limited.
If you enjoy chocolate, it can fit into a balanced diet. Just keep in mind that chocolate products vary considerably in their sugar content and how much cacao they contain.
How to include it: Choose an option you enjoy and eat it in moderation, rather than treating cacao as a concussion treatment.
5. Leafy Green Vegetables
Leafy greens such as spinach, kale, and other dark green vegetables provide vitamins, minerals, fiber, and other beneficial plant compounds.
Broccoli and other cruciferous vegetables also provide nutrients involved in normal cellular function. These foods are useful components of an overall nutritious eating pattern, although no individual vegetable has been shown to resolve persistent concussion symptoms.
How to include them: Add spinach to eggs or smoothies, roast broccoli with dinner, or include a serving of leafy greens with lunch.
6. Nuts and Seeds
Nuts and seeds provide healthy fats, vitamin E, minerals, and other nutrients. Walnuts and hazelnuts are particularly useful options to consider as part of a varied diet.
You don't need to eat large quantities or focus on one specific type of nut. Variety and consistency matter more than finding a single “brain food.”
How to include them: Keep nuts available for snacks, sprinkle seeds over meals, or add them to oatmeal and yogurt.
7. Protein-Rich Foods
Protein is important for maintaining and repairing body tissues and supporting normal body functions. Getting enough protein can be particularly helpful when fatigue or other symptoms make it harder to maintain your usual routine.
Good sources include:
Eggs
Greek yogurt and cottage cheese
Chicken and turkey
Fish
Lean meat
Beans and lentils
Tofu and other soy foods
How to include them: Try to include a protein source with your meals. If preparing food feels overwhelming, keep easy options available, such as yogurt, boiled eggs, or prepared beans.
8. Fruits and Other Colorful Plant Foods
Berries, citrus fruits, apples, and other fruits provide vitamins, fiber, and plant compounds. Eating a variety of colorful fruits and vegetables is a practical way to increase the range of nutrients in your diet.
There is no need to buy expensive specialty foods or supplements to get started.
How to include them: Add berries to breakfast, keep fruit available for snacks, or include fruit alongside a protein-rich food when you need something quick.
What Foods Should You Avoid After a Concussion?
There is no universal list of foods that everyone must avoid after a concussion. However, a few practical changes may help you maintain a balanced diet and meet your nutritional needs.
Limit Highly Processed Foods
Foods high in added sugars or heavily refined ingredients can make it harder to build a diet around nutrient-dense choices when they make up most of what you eat.
You do not need to eliminate every packaged food or treat. Instead, focus on making whole foods the foundation of your meals and snacks.
Pay Attention to Alcohol
Alcohol can affect sleep, balance, coordination, and other functions that may already be affected after a concussion. It can also make it harder to recognize how your symptoms are changing.
Avoiding alcohol during recovery is a sensible choice, particularly while you are still experiencing symptoms.
Don't Automatically Eliminate Dairy, Meat, or Carbohydrates
You may come across recommendations to remove entire food groups to reduce inflammation. But there is no single elimination diet that has been established as the best approach for everyone recovering from a concussion.
Unless you have an allergy, intolerance, medical reason, or specific dietary recommendation, you generally do not need to eliminate these foods simply because you have had a concussion.
Focus on the overall pattern of your diet rather than labeling individual foods as good or bad.
Does Nutrition Alone Help You Recover From a Concussion?
Nutrition matters, but it may not be enough to resolve persistent concussion symptoms.
You can eat salmon, add omega-3-rich foods to your diet, prioritize protein, and cut back on highly processed foods. Those can all be reasonable steps. But if you're still getting dizzy when you exercise, struggling with fatigue, dealing with headaches, or feeling worse when you try to return to normal activities, food alone may not address the factors contributing to those symptoms.
This is where many people get stuck. They keep searching for the right food, supplement, exercise, or recovery tip, hoping the next thing they try will finally make a difference.
Meanwhile, everyday life is still on hold. Work takes more effort. Exercise feels unpredictable. Social plans become harder to manage. You may find yourself constantly adjusting your day around how you feel.
You don't need another random tip to try. You need to understand which factors may be contributing to your symptoms and have a structured way to work on them.
Nutrition can be one piece of that process. The next step is looking at the other parts of recovery that may need attention, rather than continuing to rely on diet changes alone.
A More Complete Approach to Concussion Recovery
If you're still experiencing symptoms after a concussion, you may have already spent considerable time researching what to do. Perhaps you've changed your diet, tried supplements, rested more, or experimented with exercises you've found online.
But gathering information isn't the same as having a plan. And when every new strategy feels like another experiment, it can be difficult to know what to work on, how to progress, or what to try next.
I created The Concussion Solution to bring key components of concussion rehabilitation together in one guided program you can work through at home.
The program includes a 14-day guided exercise progression, along with strategies addressing exercise tolerance, autonomic retraining, dizziness, visual and cognitive symptoms, neck pain, headaches, sleep, and pacing.
Instead of continuing to piece together advice from different sources, you'll have a structured progression to follow, with exercises and strategies designed to address several areas commonly involved in persistent concussion symptoms.
You don't have to wait until you've tried every diet, supplement, or internet recommendation before taking a more organized approach to recovery.
If concussion symptoms are still dictating what you can do each day, explore The Concussion Solution to see how you can start working on the factors that may be contributing to your symptoms with a structured program you can follow at home.
Frequently Asked Questions About Nutrition After a Concussion
What is the best food to eat after a concussion?
There is no single best food for concussion recovery. A balanced diet that includes protein, fruits, vegetables, whole grains, healthy fats, and sources of omega-3 fatty acids can help you meet your nutritional needs.
Are anti-inflammatory foods good for concussion recovery?
Whole foods such as oily fish, nuts, seeds, fruits, and vegetables provide nutrients that support normal body functions. Researchers are investigating how dietary patterns and specific nutrients may affect concussion recovery, but evidence is not yet strong enough to say that particular foods will resolve symptoms or speed recovery.
Are omega-3s good after a concussion?
Omega-3 fatty acids are important for normal brain function and are being studied for their potential role after traumatic brain injury. However, evidence is still insufficient to recommend omega-3 supplements as a proven treatment for persistent concussion symptoms. Foods such as salmon, sardines, chia seeds, flaxseeds, and walnuts can be part of a balanced diet.
Should I follow a keto diet after a concussion?
A ketogenic diet has been explored in concussion and traumatic brain injury research, but it has not been established as the best diet for everyone recovering from a concussion. A restrictive diet is not necessary for most people simply because they have had a concussion.
Should I avoid sugar after a concussion?
You do not need to eliminate all sugar. Focus on eating balanced meals and limiting excessive added sugar when it displaces more nutrient-dense foods. Whole fruits can still be part of a healthy diet.
Can supplements speed up concussion recovery?
Some supplements are being studied for their potential role in concussion recovery, but the available evidence does not establish a supplement regimen that reliably speeds recovery for everyone. Supplements can also interact with medications or be unsuitable for certain health conditions, so consider your individual needs before adding them.
What if I'm eating well but still have concussion symptoms?
A nutritious diet can support overall recovery, but persistent symptoms may involve factors that food alone cannot address. Depending on your symptoms, rehabilitation may need to address exercise tolerance, dizziness, vision, neck pain, headaches, sleep, or other contributing factors.
If you are still struggling despite making changes to your diet and daily routine, consider whether a more structured approach to concussion recovery could help you identify what to work on next.
