Foods to Avoid When You Have Rheumatoid Arthritis

1. Processed and Fried Foods

Think: fast food, frozen meals, potato chips, donuts, and anything deep-fried.

These foods are typically high in trans fats and advanced glycation end products (AGEs) — compounds that can increase inflammation and oxidative stress in the body.

Better choice:

Opt for baked, grilled, or air-fried options and cook with anti-inflammatory oils like olive oil instead of vegetable shortening or margarine.

2. Refined Carbohydrates and Sugary Foods

White bread, pastries, soda, candy, and other sugar-laden items can spike blood sugar levels and trigger an inflammatory response.

High sugar intake is also linked to increased production of cytokines, proteins that play a role in inflammation and joint damage in RA.

Better choice:

Choose whole grains (like oats, quinoa, and brown rice) and natural sugars from fruits, in moderation.

3. Red and Processed Meats

Bacon, hot dogs, sausages, and even fatty cuts of beef can promote inflammation due to their saturated fat content and AGEs formed during high-heat cooking.

Some studies also link red meat consumption to higher RA risk and symptom severity.

Better choice:

Try plant-based proteins like lentils and chickpeas, or choose lean meats (like chicken or turkey) and omega-3-rich fish like salmon.

4. Dairy Products (for Some People)

While not everyone with RA is sensitive to dairy, some people report increased joint pain after consuming milk, cheese, or yogurt.

This could be due to casein, a protein in dairy that may cause inflammation in susceptible individuals.

Better choice:

Experiment with plant-based dairy alternatives (like almond, oat, or soy milk) to see how your body responds.

5. Gluten (for Some Individuals)

People with RA may have a higher risk of gluten sensitivity or celiac disease, both of which can worsen inflammation and gut issues.

If you notice increased pain or digestive symptoms after eating gluten, it might be worth testing a gluten-free trial period.

Better choice:

Use gluten-free grains like quinoa, rice, buckwheat, and corn — but be cautious of ultra-processed gluten-free products.

6. Alcohol

Heavy drinking can interfere with RA medications and worsen liver inflammation. Even moderate alcohol intake can increase inflammatory markers in some individuals.

Better choice:

If you drink, stick to moderation (e.g., one glass of wine occasionally), or avoid alcohol altogether during flare-ups or when on specific medications like methotrexate.

7. Omega-6 Fatty Acids (in Excess)

Omega-6 fats are found in vegetable oils (like corn, sunflower, and soybean oils) and processed snacks. While they’re not inherently bad, a high omega-6 to omega-3 ratio may promote inflammation.

Better choice:

Balance your fats by increasing your intake of omega-3s (found in flaxseed, chia, walnuts, and fatty fish) and reducing processed oils.

8. Salt and High-Sodium Foods

Too much sodium can trigger inflammation and increase the risk of high blood pressure, a common concern for people with RA. Processed foods are often packed with hidden salt.

Better choice:

Flavor your meals with herbs, spices, garlic, and lemon juice instead of salt.
