Managing Rheumatoid Arthritis with Diet

Home » Health » Managing Rheumatoid Arthritis with Diet

Rheumatoid arthritis (RA) is a chronic disease that usually requires lifelong management with medications, but many arthritis sufferers seek dietary recommendations that will help them manage their symptoms so that they can have a sense of control over their disease.

RA (along with cancer, heart disease, and obesity) is an inflammatory condition, which can be improved by eating a diet that inhibits (or does not stimulate) the inflammatory process. Read on to see what different diet components can help manage your arthritis…


Dietary Fats

The types of fats you include in your diet can have an impact on your arthritis symptoms. Polyunsaturated fats can be categorized as omega-6 fats and omega-3 fats. It is well documented that omega-6 fats are pro-inflammatory (they lead to inflammation) while omega-3 fats are anti-inflammatory (they prevent swelling). That’s why it’s recommended that you reduce omega-6 fat intake while increasing omega-3 fats to help reduce inflammation and help alleviate some of the pain associated with arthritis.

  • Omega-6 fats are found in soybean, safflower, sunflower, cottonseed, and corn oils – which are typically used in food preparation – and are present in many processed foods, such as snack items like crackers, cookies, potato chips, and granola bars.
  • Omega-3 fats are found in flaxseed and canola oils, but these are not significant enough dietary sources to obtain the recommended intake. These fats are also found in fatty fishes such as salmon, tuna, halibut, trout, sardines, and herring. To manage the inflammation associated with arthritis, it is recommended that you consume 3-4 grams of omega-3 fats (a combination of EPA and DHA) per day, which is most easily done by using a dietary supplement.

Antioxidants

The joints of a person who has arthritis tend to have a higher amount of free radicals, compared to those of a person who has healthy joints. Antioxidants act by binding to free radicals so they are no longer damaging to the joint. It would stand to reason that consuming antioxidants may be beneficial for a person with arthritis, but the evidence in human trials is controversial – at least when using Vitamin E, Vitamin C, and Selenium. However, the research suggests that having a low antioxidant status can put you at risk of developing RA.

Antioxidants have a number of important benefits other than managing inflammation, so it is a great idea to incorporate them into your diet. Adding more fruits, veggies, nuts, and tea will help you boost your intake of antioxidants and phytochemicals (which have also been shown to be beneficial for inflammation).

Dietary Patterns

A diet high in fat and animal products can have a detrimental effect on your arthritis. Vegetarian and vegan diets have been evaluated in research studies and found to improve arthritis symptoms. It is not well understood if it is the high plant food intake or the lower fat intake that is having the effects.

Likewise, the Mediterranean diet (high in cereals, vegetables, legumes, fruits, and olive oil) has proven to be favorable for symptom management when examined in a study with rheumatoid arthritis patients.

Food Allergies

Because food allergies can lead to increased inflammation, it is no surprise that eliminating foods that may be allergenic can have a positive effect on managing RA. Although the research has shown some promise in this area, exclusion diets (diets that do not include foods thought to be allergenic) may be of benefit to only a small number of patients. Some of the most likely offenders are milk and cheese, rice, potatoes, and wheat.


Bottom Line

There is still much to be discovered to determine the optimal diet for rheumatoid arthritis. However, there are some clear ideas as to what can be done with diet to help reduce inflammation, which is the primary side effect. Taking 3-4 grams of omega-3 fats every day (a combination of EPA and DHA), reducing your intake of meats and processed foods, and increasing your intake of fruits, vegetables, nuts, and tea will help you get on your way to better symptom management and overall health!
