When you live with ongoing pain, inflammation, fatigue, or an autoimmune condition, nutrition can feel confusing. One source recommends eliminating gluten, another promotes supplements, while another suggests an extremely restrictive “anti-inflammatory” diet.
The reality is more nuanced. Nutrition is unlikely to act like a pain medication that immediately switches pain off. However, what we eat can influence inflammation, muscle health, blood sugar regulation, nutrient status, cardiovascular health, gut health, and energy production. Over time, these factors may influence how we feel and how well the body manages chronic health conditions.
The goal is not to find a single “miracle food.” Instead, an evidence-informed approach focuses on building an eating pattern that consistently provides the nutrients the body needs while reducing excessive intake of foods that may contribute to poor metabolic health.
How Nutrition Can Influence Pain
Pain is complex. It can arise from inflammation, joint damage, nerve irritation, muscle tension, injury, altered pain processing in the nervous system, autoimmune disease, or a combination of factors.
This means there is no universal “pain diet.” However, inflammation is one component of several painful conditions. Certain dietary patterns appear to support healthier inflammatory signalling, particularly diets rich in vegetables, fruit, legumes, whole grains, nuts, seeds, olive oil and fish.
One of the best-studied examples is the Mediterranean-style diet. A recent systematic review and meta-analysis of randomized controlled trials found that Mediterranean dietary patterns can improve several markers associated with inflammation and oxidative stress.
This does not mean that following a Mediterranean diet will eliminate arthritis, fibromyalgia, back pain or another chronic pain condition. Rather, it suggests that the overall dietary pattern may create a healthier metabolic and inflammatory environment in the body. For people living with rheumatoid arthritis specifically, the American College of Rheumatology includes dietary strategies as part of an integrative approach to care while emphasizing that these interventions are used alongside not instead of appropriate medical treatment such as disease-modifying medications.
What Does an Anti-Inflammatory Diet Actually Look Like?
There is no officially defined medical diet called “the anti-inflammatory diet.” In practice, an evidence-based anti-inflammatory eating pattern looks remarkably similar to a Mediterranean-style diet. The emphasis is on eating more whole and minimally processed foods rather than attempting to eliminate dozens of individual foods. A practical foundation includes:
-
Vegetables and fruit: aim for variety and colour. Berries, leafy greens, tomatoes, peppers, cruciferous vegetables and deeply coloured produce provide fibre and numerous phytochemicals.
-
Healthy fats: extra-virgin olive oil, avocado, nuts and seeds can replace some saturated fats.
-
Omega-3-rich foods: salmon, sardines, trout, mackerel and other oily fish provide EPA and DHA.
-
High-fibre carbohydrates: oats, barley, quinoa, brown rice, legumes, lentils, beans and other minimally processed grains can support metabolic and digestive health.
-
Adequate protein: fish, eggs, poultry, dairy, legumes, tofu, tempeh and other protein sources help maintain muscle mass and recovery.
-
Herbs and spices: ginger, turmeric, garlic, cinnamon and herbs can add flavour while contributing plant compounds to the diet.
-
Fewer ultra-processed foods: frequent intake of highly processed snacks, refined carbohydrates, sugary drinks and excessive processed meats can make it more difficult to maintain healthy blood sugar, body weight and cardiovascular health.
Importantly, an anti-inflammatory eating pattern does not mean that sugar, dairy, nightshade vegetables, grains or another individual food must automatically be removed. Unless someone has a specific allergy, intolerance or medical reason for eliminating a food, unnecessarily restrictive diets can reduce dietary variety and sometimes lead to nutrient deficiencies.
Nutrition for Better Energy
Fatigue is one of the most common complaints among people dealing with chronic pain and autoimmune conditions. Nutrition can certainly contribute to fatigue—but it is important not to assume that fatigue is simply caused by eating the wrong foods.
Low energy may also be related to poor sleep, anemia, iron deficiency, vitamin B12 deficiency, thyroid disease, vitamin D deficiency, inadequate calorie intake, medication effects, depression, chronic inflammation, sleep apnea and numerous other medical conditions. Persistent or unexplained fatigue therefore deserves medical assessment.
From a nutritional standpoint, one of the most helpful strategies is consistent nourishment throughout the day. Meals that contain protein, fibre-rich carbohydrates and healthy fats tend to provide more sustained nutrition than meals consisting primarily of refined carbohydrates. For example, instead of having toast or cereal alone, consider pairing carbohydrates with protein and healthy fat:
- Greek yogurt with berries, oats and walnuts; eggs with whole-grain toast and vegetables; lentils with rice and vegetables; or salmon with potatoes and a large salad.
- Carbohydrates are not the enemy when it comes to energy. In fact, glucose is an important energy source for the body and brain. The goal is generally to favour minimally processed carbohydrate sources that also provide fibre, vitamins and minerals.
- Protein is equally important. Adequate protein helps maintain muscle mass, supports tissue repair and helps meals feel more satisfying.
- Hydration matters as well. Even mild dehydration can contribute to headaches, difficulty concentrating and feelings of fatigue.
Omega-3 Fatty Acids and Pain
Omega-3 fatty acids particularly EPA and DHA, which are found in oily fish and fish-oil supplements—have received considerable attention for their effects on inflammatory pathways. For people with rheumatoid arthritis, omega-3 supplementation has been studied for pain, swollen joints, tender joints and medication use.
The results are promising but not dramatic. A systematic review of randomized placebo-controlled trials found that omega-3 supplementation may provide small clinical benefits, but the overall quality of evidence was low or very low for several outcomes. Omega-3s should therefore be considered an adjunct rather than a primary treatment for inflammatory arthritis.
Eating fatty fish approximately twice per week is a reasonable food-first approach for many people. Fish-oil supplements may be appropriate in certain cases, but higher doses are not automatically better. Omega-3 supplements can cause gastrointestinal symptoms and may interact with medications, including anticoagulants. Very high supplemental doses have also been associated with an increased risk of atrial fibrillation in some higher-risk cardiovascular populations. Supplement dosage should therefore be individualized.
Turmeric and Curcumin
Turmeric contains several compounds called curcuminoids, the best known of which is curcumin. Curcumin has been investigated because of its effects on inflammatory signalling pathways.
The most encouraging human evidence relates to osteoarthritis, particularly knee osteoarthritis. Multiple systematic reviews and meta-analyses have reported improvements in measures of pain and joint function among people taking certain curcumin preparations. However, the studies have used different formulations, doses and absorption-enhancing technologies, which makes it difficult to determine an ideal product or dosage.
This is an important distinction. We can reasonably say that curcumin shows promise for osteoarthritis symptoms, but we cannot say that every turmeric supplement will work or that curcumin “treats inflammation” in every person. Curcumin supplements may also interact with medications or be inappropriate for certain individuals, including some people with gallbladder disease or those taking medications that affect bleeding. Using turmeric regularly as a culinary spice is generally a much simpler way to incorporate it into an overall healthy diet.
Vitamin D: Important, but Not a Universal Pain Treatment
Vitamin D is essential for bone, muscle and immune function. Low vitamin D status is relatively common, particularly in regions with limited winter sunlight, and deficiency should be identified and corrected.
However, vitamin D should not be advertised as a universal treatment for chronic pain. For example, a 2024 meta-analysis of randomized trials examining chronic low-back pain found that vitamin D supplementation did not substantially reduce pain compared with control treatments.
Some specific populations may respond differently. Research in fibromyalgia, for example, has produced more encouraging results in certain studies, although the evidence base remains substantially smaller. The most sensible approach is therefore to test and treat deficiency when clinically appropriate rather than assuming that higher doses will provide more pain relief.
Vitamin D is fat soluble and can accumulate in the body. Excessive supplementation can cause high calcium levels and, in severe cases, kidney and cardiovascular complications. The U.S. National Institutes of Health lists 4,000 IU per day as the tolerable upper intake level for most adults, although clinicians may temporarily prescribe higher amounts when treating documented deficiency.
What About Magnesium?
Magnesium plays important roles in muscle contraction, nerve function, glucose metabolism and hundreds of enzymatic reactions. Because of those roles, magnesium supplements are frequently promoted for muscle pain, headaches, sleep and fatigue. The evidence depends heavily on the condition.
Magnesium may be useful when someone is deficient and has established therapeutic roles in certain situations, including some migraine-prevention strategies. However, evidence is much less convincing for using magnesium as a general treatment for nonspecific chronic pain or fatigue. Food sources include pumpkin seeds, almonds, cashews, beans, lentils, leafy greens and whole grains.
Supplementation should be individualized because supplemental magnesium can cause diarrhea and may not be appropriate at high doses in people with significant kidney disease.
Iron, Vitamin B12 and Fatigue
Two nutrients that deserve particular attention when fatigue is a major complaint are iron and vitamin B12. Iron deficiency with or without anemia can contribute to fatigue, weakness, reduced exercise tolerance and difficulty concentrating. Vitamin B12 deficiency can also cause fatigue and neurological symptoms such as numbness, tingling or problems with balance.
The solution is not to automatically take iron or B12. Bloodwork can help determine whether deficiency is actually present. Iron supplementation in particular should generally be based on an identified need because excessive iron can be harmful and symptoms of fatigue can have many different causes.
People following vegetarian or vegan diets, people with gastrointestinal disorders, people who have had certain gastrointestinal surgeries and people taking certain medications may need additional attention to vitamin B12 status.
Autoimmune Disease and Nutrition
Autoimmune diseases occur when the immune system mistakenly targets components of the body's own tissues. Examples include rheumatoid arthritis, lupus, Hashimoto's thyroiditis, multiple sclerosis, inflammatory bowel disease and celiac disease. Because inflammation is involved in many autoimmune diseases, it is understandable that people search for an “autoimmune diet.”
Unfortunately, there is currently no single diet proven to cure or reverse autoimmune disease. Nutrition can still play an extremely valuable supportive role.
A nutrient-dense Mediterranean-style eating pattern can help improve overall diet quality while supporting cardiovascular health, metabolic health, bowel function and adequate intake of vitamins, minerals, fibre and healthy fats. This is particularly important because some inflammatory autoimmune diseases are associated with increased cardiovascular risk.
People with autoimmune disease may also have specific nutritional concerns depending on their condition or medication. For example, celiac disease can interfere with nutrient absorption. Inflammatory bowel diseases may affect iron, vitamin B12, folate or other nutrient status. Long-term corticosteroid treatment can affect bone health, making adequate calcium and vitamin D particularly important.
Nutrition should therefore be personalized to the specific autoimmune condition, laboratory findings, medications, symptoms and individual dietary tolerance. Diet should complement appropriate medical treatment rather than replace it. The American College of Rheumatology takes this same integrative approach in its rheumatoid arthritis recommendations.
Should People With Autoimmune Disease Avoid Gluten?
This is one of the most common questions surrounding autoimmune nutrition. The answer is: sometimes but not everyone needs to.
Gluten is a group of proteins naturally present in wheat, barley and rye. For people with celiac disease, gluten triggers an autoimmune response that damages the small intestine. A strict lifelong gluten-free diet is currently the primary treatment for celiac disease. This is very different from choosing gluten-free foods because they are perceived as healthier.
Someone who suspects celiac disease should ideally be tested before beginning a gluten-free diet, because removing gluten beforehand can interfere with diagnostic testing. There are also people who do not have celiac disease or a wheat allergy but experience symptoms when eating wheat-containing foods. This is often referred to as non-celiac gluten or wheat sensitivity.
This area is still evolving. Research suggests that in some people who believe they react to gluten, the symptoms may actually be related to other components of wheat, including fermentable carbohydrates known as FODMAPs, rather than gluten itself. Therefore, a gluten-free diet should not automatically be prescribed simply because someone has an autoimmune disease, chronic pain or fatigue.
Unnecessarily restrictive gluten-free diets can also become lower in fibre, iron, folate and certain B vitamins if the removed foods are not thoughtfully replaced. When gluten elimination is being considered for unexplained gastrointestinal or systemic symptoms, it is better to first investigate possible celiac disease and other causes and then consider a structured trial under professional guidance if appropriate.
Do You Need to Eliminate Dairy, Nightshades or Other Foods?
Another common approach to chronic pain and autoimmune disease is eliminating foods such as tomatoes, peppers, potatoes, eggplant, dairy, eggs, grains, legumes or soy. For most people, strong evidence does not support universally eliminating these foods to reduce inflammation.
In fact, many foods that are commonly removed such as tomatoes, peppers, legumes and whole grains provide fibre, vitamins, minerals and beneficial plant compounds. That does not mean food sensitivities never occur.
If a person repeatedly experiences reproducible symptoms after eating a particular food, that pattern deserves investigation. The goal should be identifying individual triggers, not assuming that everyone with inflammation must follow an increasingly restrictive diet. When elimination diets are used, they are generally more informative when they are temporary, structured and followed by systematic reintroduction.
A Food-First Approach to Supplements
Supplements can be useful, but they work best when they address an identifiable need. A supplement cannot compensate for chronically inadequate sleep, insufficient calories, low protein intake, poorly controlled medical conditions or an overall nutrient-poor diet.
Before starting several supplements for pain or fatigue, it can be more useful to ask: Is there a deficiency? Is there evidence that this supplement helps my particular condition? Is the dose safe? Could it interact with my medications?
For some people, omega-3s, vitamin D, iron, vitamin B12 or other nutrients may be appropriate. For others, supplementation provides little benefit because they were not deficient in the first place.
The word “natural” also does not automatically mean harmless. Supplements can have pharmacological effects and may interact with anticoagulants, blood-pressure medications, diabetes medications, immunosuppressants and other therapies.
Building a Practical Plate for Pain and Energy
Nutrition does not need to become complicated. A simple meal might contain approximately half a plate of vegetables, a source of protein, a fibre-rich carbohydrate and a source of healthy fat.
For example:
- Salmon with roasted vegetables, potatoes and olive oil.
- A lentil and chickpea bowl with quinoa, vegetables, tahini and herbs.
- Greek yogurt with berries, oats, chia seeds and walnuts.
- Chicken with brown rice, mixed vegetables and avocado.
- Tofu with vegetables, edamame and rice.
The exact foods can be adjusted to culture, preferences, medical needs, budget and digestive tolerance. Consistency matters considerably more than having a “perfect” meal.
The Bottom Line
Nutrition is one piece of the chronic pain and energy puzzle. A diet rich in vegetables, fruit, legumes, whole grains, nuts, seeds, healthy fats, adequate protein and omega-3-rich foods provides a strong evidence-based foundation for most people.
For inflammatory and autoimmune conditions, a Mediterranean-style dietary pattern is generally a much more evidence-informed starting point than highly restrictive detoxes or long lists of prohibited foods. Supplements can sometimes help, particularly when they correct a nutrient deficiency or have evidence for a particular condition, but more is not necessarily better. And while gluten must be strictly avoided in celiac disease, a gluten-free diet is not automatically required for every person experiencing inflammation, chronic pain or autoimmune disease.
Most importantly, nutrition should complement not replace appropriate investigation and medical treatment. Chronic pain and persistent fatigue can have many causes. New, severe or unexplained symptoms should be evaluated by a qualified healthcare professional so that underlying conditions and nutrient deficiencies are not overlooked.
