Quick Answer: What Is the Best Diet for Rheumatoid Arthritis?
No diet can cure rheumatoid arthritis (RA), and diet cannot replace disease-modifying medicines, which are the main treatment. However, a Mediterranean-style, anti-inflammatory diet may help ease symptoms and protects the heart, bones and general health, all of which RA affects. It is rich in vegetables, fruit, whole grains, beans, nuts, fish and olive oil, and low in sugar, processed food and red meat. A healthy weight, no smoking and care with alcohol also matter. Always tell your rheumatologist about any diet or supplement, because some interact with RA medicines.
What Is Rheumatoid Arthritis?
Rheumatoid arthritis is a long-term autoimmune condition. The immune system mistakenly attacks the lining of the joints, causing pain, swelling and, if untreated, joint damage. It is different from osteoarthritis, which is wear and tear of cartilage.
Common symptoms include:
- Pain, swelling and warmth in several joints, often the small joints of the hands, wrists and feet, usually on both sides of the body
- Morning stiffness that lasts longer than 30 to 60 minutes
- Fatigue, low-grade fever and loss of appetite
- Reduced grip strength and difficulty with daily tasks
- Firm lumps under the skin (rheumatoid nodules)
RA can also affect other parts of the body, including the eyes, lungs, heart and blood vessels, and it raises the risk of heart disease and osteoporosis. Early diagnosis and treatment protect the joints, so see a doctor promptly if you have symptoms.
How Does Diet Affect Rheumatoid Arthritis?
Diet does not switch off the immune attack, but it can help in these ways:
- Inflammation: some foods, such as oily fish, vegetables and olive oil, may help calm inflammation, while sugar, trans fats and heavily processed foods may add to it
- Heart health: people with RA have a higher risk of heart disease, so a heart-healthy diet matters
- Weight: extra weight puts load on joints and is linked to higher disease activity and a weaker response to some medicines
- Bone health: RA and steroid treatment raise the risk of osteoporosis, so calcium, vitamin D and protein matter
- Muscle: inflammation can cause muscle loss, so enough protein and activity help
- Energy and fatigue: regular, balanced meals support energy
- Gut and medicine side effects: food choices can ease nausea, constipation or stomach upset from medicines
Results from diet studies in RA are modest and often come from small trials. Be cautious about claims that a food, juice or supplement can “reverse RA” or “replace medicines”.
Eating Patterns That Support RA
Mediterranean diet
Based on vegetables, fruit, whole grains, beans, nuts, fish and olive oil, with little red meat and few sweets. It is the best-supported choice for RA, and some studies link it to lower disease activity and less pain, along with better heart health.
Anti-inflammatory eating
This is not a strict diet. It means choosing mostly whole, minimally processed foods and cutting back on sugar, refined grains, trans fats and processed meats.
Indian-style balanced plate
Fill half the plate with vegetables, a quarter with dal or lean protein, and a quarter with whole grains such as roti or brown rice. Add curd and cook with limited oil.
What about elimination, vegan, gluten-free and fasting diets?
- Some small studies of vegan, gluten-free or elimination diets show benefit in some people, but evidence is weak and not consistent.
- Short fasting can reduce symptoms for a while, but benefits do not usually last and it can cause weight and muscle loss.
- Cutting out whole food groups can lead to nutrient gaps, especially of protein, calcium, vitamin D and B12.
- If you want to try an elimination diet, do it with a dietitian, and do not stop or delay your RA medicines.
Best Foods for Rheumatoid Arthritis
1. Fatty fish and omega-3 fats
Salmon, sardines and mackerel eaten about twice a week provide omega-3 fats, which may modestly reduce joint pain and morning stiffness. Vegetarians can use walnuts, flaxseed and chia seeds, though plant omega-3 is less potent.
2. Colourful fruit and vegetables
Berries, cherries, oranges, amla, guava, tomatoes, carrots, bell peppers and broccoli provide vitamins, fibre and antioxidants.
3. Leafy green vegetables
Spinach, methi, kale and lettuce provide vitamin K, folate, calcium and antioxidants.
4. Whole grains
Oats, brown rice, millets, barley and whole wheat give fibre and steady energy. If you have coeliac disease or confirmed gluten sensitivity, choose gluten-free grains.
5. Beans, lentils and pulses
Dal, chickpeas and rajma provide plant protein, fibre and folate.
6. Nuts and seeds
A small handful of unsalted almonds, walnuts, flaxseed or pumpkin seeds gives healthy fats, vitamin E and magnesium.
7. Olive oil and other healthy oils
Olive oil contains compounds with anti-inflammatory effects. Use olive, mustard or other unsaturated oils in small amounts instead of butter and vanaspati.
8. Protein foods
Eggs, fish, chicken, curd, paneer and tofu help maintain muscle, which inflammation and steroids can break down.
9. Dairy and calcium-rich foods
Milk, curd, paneer, ragi and fortified foods support bones. Choose them as part of your calcium plan, since RA and steroids raise the risk of osteoporosis.
10. Herbs and spices
Turmeric, ginger and garlic are healthy flavourings in cooking. Evidence that they treat RA is limited, so use them as flavour, not as a replacement for medicine.
11. Probiotic foods
Curd and buttermilk may support gut health. Research on probiotics in RA is mixed, and they are not a treatment.
Key Nutrients for RA
- Omega-3 fats: may modestly reduce joint pain and stiffness. Sources: fish, walnuts, flaxseed, chia seeds.
- Vitamin D: supports bone, muscle and the immune system, and low levels are common in RA. Sources: sunlight, eggs, fatty fish, fortified milk.
- Calcium: protects bone. Sources: milk, curd, paneer, ragi, sesame, almonds.
- Protein: maintains muscle and strength. Sources: eggs, fish, dal, curd, paneer, tofu, chicken.
- Folate: needed especially if you take methotrexate, which blocks folate. Sources: leafy greens, lentils, citrus. Your doctor will usually prescribe folic acid as well.
- Vitamin B12: supports blood and nerves. Sources: dairy, eggs, fish.
- Vitamin C and E: antioxidants that support general health. Sources: amla, guava, oranges, almonds, sunflower seeds.
- Vitamin K and magnesium: support bones. Sources: leafy greens, nuts, seeds, whole grains.
- Zinc and selenium: support immunity. Sources: pumpkin seeds, chickpeas, eggs, fish, whole grains.
- Fibre: helps with weight, cholesterol and gut health. Sources: vegetables, fruit, whole grains, pulses.
Weight and RA
Extra body weight puts pressure on weight-bearing joints and adds to inflammation, because body fat releases inflammatory chemicals. Obesity is linked to higher RA disease activity and a poorer response to some medicines. Being underweight, or losing muscle, is also harmful.
- Aim for a healthy weight with a balanced diet and activity, and avoid crash diets.
- Lose weight gradually, about 0.5 to 1 kg a week, if your doctor advises it.
- Choose high-fibre, high-protein, lower-sugar foods to feel full.
- Control portions of rice, roti, sweets and fried snacks.
- Keep moving with low-impact exercise, as your joints allow.
- If you are losing weight without trying, or have poor appetite, tell your doctor, since it can be a sign of active disease.
Foods and Habits to Limit
- Sugar and sweet drinks: sweets, soft drinks and packaged juices add calories and may add to inflammation.
- Refined grains: white bread, maida products and bakery items.
- Fried and ultra-processed foods: chips, fast food, namkeen and packaged snacks.
- Trans fats and excess saturated fat: found in vanaspati, fried street food and fatty meat.
- Processed and red meat: keep portions small and occasional.
- Excess salt: it can raise blood pressure, especially if you take steroids or anti-inflammatory painkillers.
- Alcohol: it can add to liver strain with methotrexate and leflunomide and irritate the stomach with anti-inflammatory painkillers. Many doctors advise avoiding it or keeping it very low, so ask your rheumatologist.
- Smoking and tobacco: smoking raises the risk of developing RA, makes it more severe and reduces the benefit of some medicines. Quitting is one of the most useful steps.
- Crash diets and fad diets: they can cause muscle loss and nutrient gaps.
- “Immune-boosting” products: RA is caused by an overactive immune system, so do not take products such as echinacea or high-dose immune boosters without your rheumatologist’s approval.
Do Nightshades, Dairy or Gluten Make RA Worse?
Many people believe that nightshade vegetables (tomatoes, potatoes, brinjal and peppers), dairy or gluten worsen RA. Research has not shown that nightshades or dairy affect RA in most people, and these foods are nutritious. A small number of people may notice that a certain food triggers their symptoms. If you suspect one, keep a food and symptom diary and discuss it with your doctor or dietitian before cutting it out. Gluten should only be removed if you have coeliac disease or a confirmed intolerance, because testing is unreliable once you stop eating it. RA and coeliac disease can occur together.
Managing Common RA Problems Through Diet
Fatigue
- Eat regular meals and snacks with protein and complex carbohydrates.
- Stay hydrated.
- Ask your doctor to check iron, B12, vitamin D, thyroid and blood counts, since anaemia and thyroid problems are common in RA.
- Prepare meals in batches on better days.
Anaemia
RA inflammation and some medicines can cause anaemia. Eat iron-rich foods (leafy greens, lentils, beetroot, dates, lean meat) with vitamin C, and ask your doctor to test before taking iron tablets.
Stomach upset and nausea
Methotrexate, anti-inflammatory painkillers and other medicines can cause nausea or stomach pain. Take medicines with food as advised, eat small meals and avoid heavy, greasy or very spicy foods. Tell your doctor if it persists.
Constipation
Eat fibre from vegetables, fruit, whole grains and pulses, drink enough fluids and stay active.
Dry mouth and dry eyes (Sjögren’s)
Some people with RA have Sjögren’s syndrome. Sip water often, choose moist, soft foods, use sauces and gravies, avoid very dry or salty foods, and keep up dental care.
Hand pain and cooking
- Use adapted kitchen tools, such as jar openers, lightweight pans, electric can openers and knives with thick handles.
- Choose pre-cut vegetables and ready-to-use ingredients on bad days.
- Cook in batches and freeze portions.
- Sit while preparing food.
- An occupational therapist can suggest aids and joint protection techniques.
Weight changes
Steroids can raise appetite and cause weight gain, while active disease can cause weight and muscle loss. Weigh yourself regularly, and ask your doctor or dietitian for help with unplanned changes.
Bone, Heart and Overall Health
Bone health
RA, steroids and reduced activity raise the risk of osteoporosis.
- Get enough calcium and vitamin D from food, and supplements if needed.
- Do weight-bearing and strength exercise as your joints allow.
- Ask your doctor about a bone density scan.
- See our guides to diet tips for osteoporosis and diet tips for osteopenia.
Heart health
People with RA have a higher risk of heart disease. Keep blood pressure, cholesterol and blood sugar in check with a Mediterranean-style diet, less salt and saturated fat, regular exercise and no smoking.
Gout and other joint conditions
Joint pain is not always RA. Gout causes sudden severe pain, often in the big toe, and diet matters there. For related conditions, see our guides to diet tips for osteoarthritis and diet tips for ankylosing spondylitis.
Medicines and Diet
Never stop or change an RA medicine without your doctor’s advice. Untreated RA can cause permanent joint damage.
- Methotrexate: it is usually taken once a week, not daily, and taking it by mistake every day can be dangerous. It lowers folate, so doctors usually prescribe folic acid on a different day, so follow their instructions. Avoid alcohol or keep it to a minimum, since the combination can harm the liver. Drink plenty of fluids. Tell your doctor about mouth ulcers, a new cough, breathlessness, fever or unusual bruising.
- Leflunomide: it can affect the liver, blood pressure and blood counts, so avoid alcohol and follow your monitoring tests. It can cause diarrhoea and weight loss.
- Sulfasalazine: take it with food and plenty of fluids, and your doctor may advise folic acid. It can turn urine orange.
- Hydroxychloroquine: take it with food to reduce nausea. Keep up regular eye checks.
- Steroids (prednisolone): take them with food, preferably in the morning. They can raise appetite, weight, blood sugar and blood pressure and cause fluid retention and bone loss. Limit salt and sugar, eat enough protein, calcium and vitamin D, and never stop them suddenly.
- Anti-inflammatory painkillers (NSAIDs such as ibuprofen, naproxen, diclofenac): take them with food, use the lowest dose for the shortest time, and ask your doctor if you have stomach ulcers, kidney, heart or blood pressure problems. Avoid alcohol.
- Paracetamol: do not exceed the daily dose, and check combination products for hidden paracetamol.
- Biologic medicines (such as TNF inhibitors, tocilizumab, rituximab, abatacept): they lower the immune system’s defences, so food safety matters. Wash fruit and vegetables well, cook meat, fish and eggs thoroughly, avoid raw or undercooked shellfish, and avoid unpasteurised dairy and soft cheeses made from it.
- JAK inhibitors (such as tofacitinib, baricitinib, upadacitinib): they can raise cholesterol, so a heart-healthy diet matters, and they also lower immune defences, so follow the same food safety advice.
- Warfarin and blood thinners: keep vitamin K foods, such as leafy greens, steady from day to day.
- Grapefruit: it can interact with some medicines. Ask your pharmacist if you take statins or other medicines alongside your RA treatment.
- Supplements and herbal products: some interact with RA medicines or affect the immune system or liver, so tell your doctor about everything you take.
Do Supplements Help RA?
Evidence for most supplements is limited, and none replace RA medicines. Always check with your rheumatologist first.
- Fish oil (omega-3): studies suggest a modest reduction in joint pain, stiffness and the need for painkillers in some people. It can raise bleeding risk with blood thinners and may cause stomach upset or a fishy aftertaste.
- Vitamin D and calcium: useful if a test shows low levels or your doctor advises them, and often recommended with steroids.
- Folic acid: usually prescribed alongside methotrexate or sulfasalazine, so take it as directed.
- Turmeric and curcumin: some studies show modest benefit, but product quality varies, and concentrated products can interact with medicines and, rarely, harm the liver.
- Probiotics: results are mixed.
- Gamma-linolenic acid (evening primrose, borage and blackcurrant seed oil): evidence is limited, and these can interact with some medicines. Borage oil may contain compounds that can harm the liver unless the product is certified free of them.
- Collagen type II and glucosamine: evidence is limited or mixed.
- Thunder god vine (Tripterygium wilfordii): some products have been studied, but it can cause serious side effects, including harm to fertility, bone marrow and the liver, so avoid it unless a specialist advises.
- Echinacea, high-dose vitamin C and “immune boosters”: they may stimulate an already overactive immune system and are not advised.
- Iron: only take it if a test shows you are deficient.
- Herbal and ayurvedic products: some contain hidden steroids, NSAIDs or heavy metals. Tell your doctor before using any.
- Be careful of products that promise to “cure RA”, “reverse arthritis” or “replace your medicines”.
Diet Tips Alongside Stem Cell Treatment
Good nutrition supports overall health during any treatment. For patients considering stem cell treatment, a balanced diet complements medical care but does not guarantee results. Stem cell therapy for rheumatoid arthritis is still experimental and is not an established or standard treatment. Intensive treatments using a person’s own blood stem cells (autologous haematopoietic stem cell transplantation) have been tried only in a small number of severe, treatment-resistant cases in specialist centres, and mesenchymal stem cell treatments are being studied in clinical trials. Results are not yet proven, and unregulated products have caused harm in some patients. Please discuss any treatment with your own rheumatologist first. Your Viezec doctor will explain what to realistically expect for your own case. Keep taking your prescribed RA medicines, since stopping them can cause a flare and joint damage, and never stop them without your doctor’s advice.
Before treatment
- Eat regular, balanced meals with enough protein, vitamin D and calcium.
- Keep blood sugar and blood pressure as well controlled as your doctor advises.
- Stay well hydrated.
- Share all medicines and supplements with the clinic, including methotrexate, steroids and biologics.
- Follow any food safety advice if your immunity is lowered.
After treatment
- Continue a balanced, nutrient-rich diet.
- Follow food safety advice, particularly if your immune system is weakened.
- Avoid smoking and limit alcohol.
- Follow all diet and aftercare instructions.
- Do not start new high-dose supplements without medical advice.

Sample One-Day Meal Plan
- Breakfast: oats porridge with berries, walnuts and flaxseed, or a vegetable omelette with whole-wheat toast
- Mid-morning: an orange, guava or papaya, with a glass of milk or buttermilk
- Lunch: dal, brown rice or roti, spinach or methi sabzi, curd and salad
- Snack: a handful of almonds and pumpkin seeds, with green tea or buttermilk
- Dinner: grilled or steamed fish (salmon, sardines or mackerel), paneer or tofu with plenty of vegetables and soup
- Through the day: water
Adjust the plan for your culture, weight goals, diabetes, kidney health, medicines (including your methotrexate day and folic acid timing) and your doctor’s advice.
How Long Does It Take to See Benefits From Diet Changes?
Diet works slowly in RA. Better eating habits can improve energy, digestion and weight within weeks. Studies of anti-inflammatory diets and fish oil usually show modest effects on pain and stiffness after about three months or more. Diet does not stop joint damage, so medicines remain essential. Results differ from person to person.
When Should You Seek Urgent Medical Care?
Get urgent medical help if you notice:
- A hot, red, swollen, very painful joint, especially with fever or chills, which can signal a joint infection
- Fever, chills, a new cough, breathlessness or other signs of infection if you take immune-lowering medicines
- Chest pain, severe breathlessness or a swollen, painful calf
- Black, tarry stools, vomiting blood or severe stomach pain, which can signal bleeding from anti-inflammatory painkillers or steroids
- Mouth sores, unusual bruising or bleeding, a sore throat with fever, or yellowing of the skin or eyes if you take methotrexate or leflunomide
- Sudden vision changes or severe eye pain or redness
- Severe neck pain with numbness, weakness or tingling in the arms or legs, which can signal a problem in the neck spine in RA
- Swelling of the face or throat, a rash or trouble breathing after a medicine
- Very high thirst, frequent urination or confusion if you take steroids and have diabetes
When Should You Talk to a Doctor or Dietitian?
Seek advice if you:
- Have joint pain, swelling or morning stiffness lasting more than a few weeks, especially in several joints
- Are losing weight without trying, or gaining weight quickly
- Have constant fatigue, poor appetite or signs of anaemia
- Take methotrexate, leflunomide, steroids, biologics or several medicines
- Have diabetes, high blood pressure, heart disease, kidney disease or osteoporosis along with RA
- Smoke or drink and want help to cut down
- Want to try an elimination diet, fasting or high-dose supplements, or herbal products
Frequently Asked Questions
What is the best diet for rheumatoid arthritis?
A Mediterranean-style diet with plenty of vegetables, fruit, whole grains, beans, nuts, fish and olive oil, and limited sugar, refined grains and processed food. It supports joint, heart and bone health, but it does not replace RA medicines.
Can diet cure rheumatoid arthritis?
No. Diet cannot cure RA or stop joint damage. It may help ease symptoms and support general health alongside medicines.
What foods should I avoid with rheumatoid arthritis?
Limit sugar and sweet drinks, refined grains, fried and ultra-processed foods, trans fats and processed meat. Ask your doctor about alcohol, and do not smoke.
Do nightshade vegetables or dairy make RA worse?
There is no good evidence that they do for most people. If you notice a clear trigger, keep a diary and discuss it with your doctor or dietitian before cutting the food out.
Should I go gluten-free if I have RA?
Only if you have coeliac disease or confirmed gluten sensitivity. Ask about testing before removing gluten.
Does fish oil help rheumatoid arthritis?
Studies suggest a modest reduction in joint pain and stiffness in some people. Ask your doctor first, especially if you take blood thinners.
Can I drink alcohol while taking methotrexate?
Many doctors advise avoiding alcohol or keeping it very low, because the combination can harm the liver. Ask your rheumatologist what is safe for you.
Is turmeric good for arthritis?
Turmeric in cooking is fine. Concentrated supplements show modest benefit in some studies, but quality varies and they can interact with medicines, so ask your doctor first.
Will losing weight help my RA?
For people who are overweight, gradual weight loss can reduce joint load and may lower disease activity. Avoid crash diets.
