This article will cover the main foods to avoid for arthritis and help you decide if you’d be better off without them in your diet.

Here’s a summary of what we’ll cover:

  • Arthritis can occur as a result of wear and tear in the joints or as an autoimmune response in the case of rheumatoid arthritis. 
  • There are some foods to avoid for arthritis as they can worsen inflammation in the joints, causing stiffness and pain.

What are the types of arthritis

What are the types of arthritis?

There are different types of arthritis that are caused by different factors from genetics, injury and lifestyle factors. 

People with arthritis experience joint pain and stiffness in joints such as the knees, fingers, wrists and elbows. 

It can cause great discomfort and is one of the main things that causes mobility issues in elderly people, especially if not managed properly.

What is the connection between food and arthritis?

As the saying goes, you are what you eat. 

When we eat something, our body takes in essential nutrients we need to function and gives us energy. 

But it also responds and processes proteins and fats that prompt an immune response to something it doesn’t like, causing inflammation.

If you eat foods that cause inflammation then naturally you’ll suffer with chronic inflammation-related symptoms.

junk food causing arthritis

Beware modern food

We live in a society where we want food that’s easy to eat, cheap and convenient for our busy lifestyles. 

This has created an ultra-processed food culture in which much of what we eat is pre-made and ready to go. 

But this means that our food contains lots of ingredients for flavour as well as preservation that our bodies just don’t need. 

Consuming these processed foods leads to inflammation around the body which can be painful and cause other health issues.

What are the foods to avoid for arthritis

What are the foods to avoid for arthritis?

It is clear to health professionals and people living with arthritis that there are some foods that cause the condition to worsen. 

This is due to the way the body reacts to certain foods, which cause an inflammatory response. 

Many of the suggested foods to avoid for arthritis have not yet been medically clarified as arthritis-causing foods. 

And not all of these foods will be problematic for all people with arthritis, so it’s important that you listen to your body and find what works for you.

avoid gluten for arthritis


Gluten is found in products made from wheat, barley or rye all of which can cause inflammation. 

This is especially prominent for people with Coeliac disease, in which gluten triggers an immune response causing inflammation in the small intestine. 

This may also affect the joints leading to arthritis, which people with Coeliac are more likely to develop. 

The connection between non-Coeliac, gluten and arthritis isn’t strictly clear, but it seems that limiting gluten can be beneficial for arthritis for some people.

AGEs causing arthritis


AGE stands for Advanced Glycation End products. These are molecules which are found in processed foods including meat and dairy products.

They exist naturally in uncooked animal products, but are activated during food processing in reactions between sugars and proteins or fats. 

These foods include:

  • Bacon and ham
  • Butter and margarine 
  • Mayonnaise
  • Fried eggs
omega-6 vegetable oils

Vegetable oils

Some vegetable oils such as sunflower, soy, sesame and corn are high in omega-6 fatty oils. 

Unlike omega-3 oils, which fight inflammation, high levels of omega-6 oils are thought to contribute to inflammation.

Processed food

Highly processed food such as fast food, baked goods and sweet cereals can cause inflammation and arthritis.

This is due to them containing high levels of refined grains, added sugar, preservatives and fructose.

Eating a lot of these foods causes inflammation in the body as well as obesity in the long-term, which can also contribute to arthritic symptoms. 

Processed food is generally bad for your health, so should be limited, especially if you already have arthritis.

high sodium foods to avoid for arthritis

High sodium foods

Having extra salt in your diet can cause inflammation as you retain sodium in your body cells which can affect the immune system. 

High sodium foods include processed meats, salted nuts, pizza, pasta sauces and some bread products. 

If you have rheumatoid arthritis, you should avoid these kinds of foods as they could cause oedema, or swelling in the legs and ankles. 

Here’s everything you need to know about what causes swelling and how to get rid of swollen ankles fast.

Are there any myths on foods to avoid for arthritis?

The short answer is yes. 

There are a number of myths around foods to avoid for arthritis, but much more research is needed to say anything conclusive. 

Therefore, it’s important to stay informed about potential triggers and helpers for arthritis pain, but be wary about taking these anecdotes as medical truths.

Are there any myths on foods to avoid for arthritis

Can any fruit and vegetables cause inflammation?

One food group that has been demonised as foods to avoid for arthritis is the nightshades. 

This group includes aubergines, potatoes, peppers and tomatoes which all contain a toxin called solanine

Some people claim that their arthritis is triggered by nightshades, but there is no conclusive medical evidence to suggest they are harmful. 

If your arthritis becomes worse after consuming any of these foods, avoid eating them, however they are not generally seen as foods to avoid for arthritis.

  • A wide variety of fruits and vegetables
  • Legumes such as beans and lentils
  • Oily fish such as salmon 
  • Nuts and olive oil
  • Limited red meat and saturated fats
  • No added sugars or processed foods
