Nutrition Diet: What not to eat in rheumatoid arthritis?

4 min read

Up to 75% of people living with rheumatoid arthritis (RA) believe their diet plays a key role in managing symptoms. Understanding what not to eat in rheumatoid arthritis can be a powerful complement to medical treatment, helping to minimize flare-ups and reduce inflammation throughout the body.

Quick Summary

Diet can significantly impact rheumatoid arthritis symptoms. Certain foods increase inflammation and may trigger flares. Limiting processed foods, sugary drinks, red meats, and certain fats can help manage this autoimmune disease.

Key Points

  • Avoid Sugary Items: Foods and drinks with high amounts of added sugar can increase inflammatory cytokines, worsening RA symptoms.

  • Limit Processed and Red Meats: Saturated fats and advanced glycation end products (AGEs) in these foods are linked to higher inflammation levels.

  • Cut Out Trans and Excess Omega-6 Fats: Trans fats and an imbalance favoring omega-6s, common in processed and fried foods, can fuel inflammatory processes.

  • Beware of High-Salt and Refined Carbs: Excessive salt intake and refined carbohydrates both trigger inflammation and should be minimized for RA symptom control.

  • Personalize Your Approach: Individual sensitivities to foods like nightshades, gluten, and high-fat dairy vary; consider a supervised elimination diet to identify personal triggers.

  • Prioritize Whole Foods: Focus on an anti-inflammatory diet rich in whole foods, like fruits, vegetables, and fatty fish, to counteract inflammatory effects.

In This Article

For individuals with rheumatoid arthritis (RA), a chronic inflammatory autoimmune disease, managing symptoms is a daily priority. While medication is the cornerstone of treatment, a proactive dietary approach can play a significant role in reducing inflammation and improving quality of life. The key is to identify and limit foods that act as inflammatory agents in the body. By making informed food choices, you can support your treatment plan and potentially reduce the frequency and severity of flare-ups.

The Prime Instigators: Foods that Fuel Inflammation

Many common foods can contribute to systemic inflammation, which is the root cause of RA symptoms like joint pain, swelling, and stiffness. Avoiding or limiting these items is a strategic step towards better symptom management.

Sugary Foods and Beverages

Excessive sugar intake is a major promoter of inflammation. It triggers the release of inflammatory proteins called cytokines and contributes to the formation of Advanced Glycation End products (AGEs), both of which can intensify RA symptoms. Sugary foods often lack essential nutrients, providing only 'empty calories' that can also lead to weight gain, adding stress to joints.

  • Foods to limit: Cookies, cakes, pastries, candy, sugary cereals, and desserts.
  • Drinks to avoid: Sodas, fruit juices (which are often high in added sugar), and energy drinks.

Red and Processed Meats

Red meat contains high levels of saturated fat, which has been linked to increased inflammation. The grilling, broiling, or roasting of meat at high temperatures can also create inflammatory AGEs. Processed meats, like bacon, sausages, and deli meat, are particularly problematic due to their high content of saturated fat, salt, and preservatives.

Processed and Fried Foods

These convenient staples are loaded with inflammatory compounds. They are often high in unhealthy fats, including trans fats and an excessive amount of omega-6 fatty acids, which can disrupt the body's omega-3 to omega-6 balance and increase inflammation. Examples include:

  • Fast food burgers, tacos, and fried chicken.
  • Packaged snacks, chips, and crackers.
  • Prepackaged meals, frozen dinners, and baked goods.

Refined Carbohydrates

Refined carbohydrates, found in white bread, white rice, and many baked goods, are quickly converted into sugar in the body. This causes a rapid spike in blood sugar, triggering an inflammatory response. Opting for whole grains, rich in fiber and nutrients, is a healthier alternative.

High-Salt Foods

Excessive sodium intake can exacerbate inflammation in the body and may also increase the risk of high blood pressure. Many processed and fast foods are laden with salt. Focusing on fresh ingredients and seasoning with herbs and spices instead of salt can be beneficial.

The Grey Area: Foods that Affect Some People, but Not All

Some foods' effect on RA symptoms is less certain and can be highly individual. Paying close attention to your body’s response is crucial.

Nightshade Vegetables

Nightshades, including tomatoes, potatoes, eggplants, and peppers, have a long-standing reputation for worsening arthritis, although scientific evidence for a widespread connection is limited. They contain solanine, an alkaloid, but the amount in edible parts is generally not harmful. If you suspect nightshades are a trigger for you, try a supervised elimination diet to confirm.

Gluten-Containing Grains

For those with celiac disease or gluten sensitivity, gluten can cause systemic inflammation that may mimic or worsen RA symptoms. While not a universal trigger for all RA patients, some find symptom improvement on a gluten-free diet. A diagnostic evaluation for celiac disease or a temporary elimination diet under professional guidance is recommended if you suspect a link.

High-Fat Dairy Products

Research on dairy's effect on RA is mixed. Some studies link high-fat dairy to increased inflammation, while others find fermented dairy beneficial. Many people find that avoiding high-fat versions of milk, cheese, and butter can reduce symptoms, but it is not a universally recognized trigger.

Comparison of Inflammatory vs. Anti-Inflammatory Diet Choices for RA

Inflammatory Foods (Limit/Avoid) Anti-Inflammatory Foods (Encourage)
Processed snacks (chips, crackers) Nuts and seeds (almonds, walnuts, chia)
Fried foods (fries, chicken) Fatty fish (salmon, sardines, mackerel)
Red & processed meats (bacon, beef) Lean poultry, beans, and legumes
Sugary drinks (soda, juices) Water, green tea, herbal tea
Refined carbs (white bread, pasta) Whole grains (oats, brown rice, quinoa)
High-salt foods (fast food, canned soups) Herbs and spices (turmeric, ginger)
Trans fats (margarine) Healthy fats (olive oil, avocado)
High-fat dairy (full-fat cheese, butter) Low-fat dairy (yogurt) or alternatives (if sensitive)

Final Recommendations and the Importance of Personalization

Dietary changes for rheumatoid arthritis are not a one-size-fits-all solution. Your body's reaction to certain foods is unique, and what triggers a flare-up in one person may not affect another. Working with a registered dietitian can help you navigate these dietary restrictions, identify specific trigger foods through an elimination diet, and create a sustainable, nutrient-rich eating plan. Remember, diet is a supportive strategy and should never replace prescribed medications or the advice of your rheumatologist.

Frequently Asked Questions

Excess sugar intake can increase the level of inflammatory proteins called cytokines in your body, potentially making RA symptoms worse and contributing to long-term inflammation.

Scientific evidence on nightshades worsening RA is mixed and limited. Some people report anecdotal improvements after eliminating them, but it is not a universal trigger. An elimination diet under medical supervision can help determine your personal sensitivity.

Yes, red and processed meats are high in saturated fats and contain inflammatory compounds called AGEs. They have been linked to increased inflammation markers and worsened RA symptoms.

For some individuals with celiac disease or gluten sensitivity, gluten can trigger an inflammatory immune response. While not all RA patients are affected, some find symptom relief on a gluten-free diet. Consult a healthcare provider before eliminating gluten.

You should limit or avoid trans fats found in many processed foods and excess omega-6 fatty acids found in some vegetable oils and fried foods. Focus on balancing your diet with healthy omega-3 fatty acids from fish and olive oil.

Processed foods are often high in trans fats, added sugars, and excessive salt, all of which contribute to systemic inflammation and can worsen RA symptoms. Limiting them is recommended to help manage the condition.

No, dietary changes are a complementary strategy and not a cure for RA. They can help manage symptoms and reduce inflammation, but they should be used in conjunction with your prescribed medical treatment plan.
