Rheumatoid arthritis (RA) is a chronic autoimmune condition that causes inflammation in the joints and other parts of the body.

While there is no one definitive cause of RA, researchers have identified a number of possible risk factors, including genetics, environmental factors, and lifestyle factors like diet and nutrition. In recent years, there has been growing interest in the role that dietary choices may play in triggering RA flare-ups and exacerbating symptoms in people with the condition.

Foods that Trigger Rheumatoid Arthritis Flare-Ups

While there is no one-size-fits-all diet for people with RA, there are certain foods and dietary patterns that have been found to trigger flare-ups and make symptoms worse. Below, we discuss some of the most common culprits:.

Processed Foods

Foods that are heavily processed and high in refined sugars and carbohydrates have been linked to inflammation in the body, including joint inflammation that can exacerbate RA symptoms.

This includes foods like candy, soda, white bread, and other refined carbs.

Red Meat and Fried Foods

Foods that are high in saturated fats, such as red meat and fried foods, can also trigger inflammation in the body. Some studies have suggested that there may be a link between high consumption of red meat and increased risk of developing RA.

Dairy Products

Dairy products like milk, cheese, and yogurt contain a protein called casein that can cause inflammation in some people. If you have RA, you may want to consider limiting or avoiding dairy products to see if it helps alleviate your symptoms.

Alcohol

Drinking alcohol can exacerbate RA symptoms, in part because it can disrupt sleep patterns and cause dehydration. Additionally, some types of alcohol, such as beer, contain gluten, which can cause inflammation in some people.

Gluten

For some people with RA, gluten can be a trigger for inflammation and joint pain. Gluten is a protein found in wheat, barley, and rye, and is commonly found in foods like bread, pasta, and cereal.

Omega-6 Fatty Acids

Foods that are high in omega-6 fatty acids, such as vegetable oils and processed foods, can promote inflammation in the body and worsen RA symptoms.

To help alleviate symptoms, try replacing these foods with healthier options like extra-virgin olive oil, nuts, and seeds.

Additives

Many processed foods contain additives like preservatives, flavorings, and artificial colors that can trigger inflammation and exacerbate RA symptoms. To reduce your risk of trigger flare-ups, try to eat whole, unprocessed foods as much as possible.

Nightshade Vegetables

Some people with RA report that nightshade vegetables like tomatoes, potatoes, peppers, and eggplants can trigger joint pain and inflammation.

While the evidence for this is not conclusive, it may be worth avoiding these foods if you experience symptoms after eating them.

Sugar

Like other refined carbs, sugar can trigger inflammation in the body and worsen RA symptoms. To help reduce your risk of flare-ups, try to limit your intake of sugary foods and drinks.

Caffeine

High amounts of caffeine can interfere with sleep patterns and exacerbate symptoms of RA. To avoid triggering a flare-up, try to limit or avoid caffeinated drinks like coffee and tea.
