Rheumatoid arthritis (RA) is a chronic inflammatory disorder that primarily affects the joints. In RA, the immune system mistakenly attacks the tissues in the joints, leading to inflammation, pain, and stiffness.

While there is no specific diet that can cure RA, certain foods have been shown to worsen symptoms. In this article, we will discuss 30 foods that can aggravate rheumatoid arthritis.

1. Sugar

Consuming excess sugar can worsen inflammation in the body, which can exacerbate RA symptoms. Foods high in added sugar include soda, candy, baked goods, and processed snacks.

2. Fried Foods

Fried foods, such as fried chicken and French fries, are high in unhealthy fats, which can contribute to inflammation in the body.

3. Red Meat

Red meat is high in saturated fat, which can worsen inflammation in the body. Instead, opt for lean proteins such as fish and poultry.

4. Dairy Products

Dairy products, such as milk and cheese, contain casein and whey, which can trigger inflammation in some people with RA.

If you suspect dairy may be aggravating your symptoms, try eliminating it from your diet for a few weeks to see if your symptoms improve.

5. Processed Foods

Processed foods, such as canned soups and frozen meals, often contain high amounts of sodium, sugar, and unhealthy fats, all of which can contribute to inflammation in the body.

6. Gluten

Some people with RA may have a sensitivity to gluten, a protein found in wheat, rye, and barley. If you suspect gluten may be contributing to your symptoms, try eliminating it from your diet for a few weeks to see if your symptoms improve.

7. Alcohol

Alcohol can worsen inflammation in the body and can also interfere with your medication. It’s important to talk to your doctor about whether it’s safe for you to consume alcohol.

8. Saturated Fats

Just like with red meat and fried foods, consuming excess saturated fat can contribute to inflammation in the body. Saturated fats are found in high amounts in fatty meats, butter, and cheese.

9. Artificial Sweeteners

Artificial sweeteners, such as aspartame and sucralose, can trigger inflammation in some people with RA.

10. Nightshade Vegetables

Some people with RA may be sensitive to nightshade vegetables, such as tomatoes, peppers, and eggplant. While more research is needed, some studies suggest that these vegetables can exacerbate RA symptoms in certain individuals.

11. Hydrogenated Oils

Hydrogenated oils, often found in margarine and processed baked goods, contain trans fats which can contribute to inflammation in the body.

12. White Flour

White flour, found in many baked goods and refined carbohydrates, can contribute to inflammation in the body.

13. Caffeine

Caffeine can interfere with the way the body absorbs calcium, which can contribute to bone loss in people with RA. It’s important to talk to your doctor about how much caffeine is safe for you to consume.

14. Salt

Consuming excess salt can contribute to inflammation in the body and can also raise blood pressure.

15. Omega-6 Fatty Acids

While omega-6 fatty acids are important for overall health, consuming too much can contribute to inflammation in the body. Omega-6 fatty acids are found in high amounts in vegetable oils, such as corn and soybean oil.

16. Processed Meats

Processed meats, such as hot dogs and lunch meats, are high in saturated fat and sodium, both of which can worsen inflammation in the body.

17. High-Glycemic Index Foods

Foods with a high glycemic index, such as white bread and potatoes, can cause a rapid spike in blood sugar levels, which can contribute to inflammation in the body.
