  • Joint Swelling – The first sign of inflammation in rheumatoid arthritis is swelling of joints that feel warm to the touch.

9 Deadly Inflammation Causing Foods fatal for Inflammatory Arthritis

Arthritis is a painful condition that involves inflammation, swelling and joint pain. Although there is not strict diet for arthritis, excluding certain foods from the diet can help in reducing the symptoms of rheumatoid arthritis and calming the excruciating pain.

Sugar and Refined Carbohydrates

It is difficult to resist the temptation of desserts, chocolate bars, pastries, soda and other sweet treats but sugar and refined carbohydrates must be eliminated from a rheumatoid arthritis patient’s diet because processed sugars trigger inflammation in the body by increasing the release of cytokines – the inflammatory messengers.

Sugar and Refined Carbohydrates

Fruit juices, canned fruits and other sweets are loaded with fructose and sucrose which are poisons by themselves. Refined carbs such as white flour, white rice and sugar) are also called pro-inflammatory carbs. Such carbs are not used as energy; rather they are stored as inflammatory saturated fats in the body which triggers inflammation and cause heart disease.

Salt and Preservatives

Excessive salt in food and added table salt in food is one of the main causes of inflammation. Processed foods and ready to eat meals contain high levels of sodium and preservatives to increase their shelf life. Regular consumption of these foods results in the inflammation of joints.

Salt and Preservatives

Salt intake promotes water retention and causes the blood vessels to expand. The swollen veins induce uncomfortable pressure on the inflamed joints and aggravate the condition of rheumatoid arthritis. It is best to limit the daily intake of sodium to 1500 milligrams per day.

Dairy Products

Dairy products are one of the most inflammatory foods apart from gluten and therefore must be excluded from the arthritis diet. The proteins casein and whey, found in milk products flare up Rheumatoid arthritis symptoms.

Dairy Products

People suffering from rheumatoid arthritis often report intolerance to milk because their bodies develop antibodies to milk protein in order to protect itself from what it incorrectly perceives as a harmful substance. But, in addition to milk, these antibodies also turn against the body and lead to auto-immune diseases such as rheumatoid arthritis. Therefore, it is best eliminate milk and dairy products from the diet for arthritis and opt for plant-based sources of protein such as lentils, quinoa, spinach and tofu.

Fried and Processed Foods

Fried and processed foods cause chronic inflammation and promote the symptoms of rheumatoid arthritis. Overcooked foods and foods prepared at high temperatures such as French fries, onion rings, fried chicken, barbecued foods, etc., induce the production of toxins known as advanced glycation end products (AGES) that the body treats as an invader.

Fried and Processed Foods

The AGES are created when proteins are bound to glucose molecules. As the body’s immune system tries to break these AGES apart, the immune cells release inflammatory cytokines in large quantities. This process promotes inflammation and enhances the symptoms of rheumatoid arthritis.


It has been noticed that for people suffering from rheumatoid arthritis, changing over to a vegetarian diet helps in reducing the pain in joints. This is because meat contains a high amount of fat and calories and the fat in meat is readily metabolized into pro-inflammatory chemicals that cause swelling and painful inflammation in joints.


The saturated animal fats make the gut leaky and promotes the release of bacterial toxins known as endotoxins into the blood stream and the immune system starts fighting the bacteria that cause excessive inflammation.


There is a reason why more and more people are opting for a gluten-free diet. Gluten is a type of protein that is commonly found in grains such as barley, wheat, rye and spelt.


In case of gluten intolerance, the immune system of the body views the proteins present in gluten – gliadin and glutenin as some foreign invader and therefore turns against the body and leads to autoimmune diseases such as rheumatoid arthritis. It also worsens joint pain and swelling. Therefore, it is best to opt for gluten-free cereals and wheat products.

Corn OilCorn Oil

Vegetable oil such as corn oil triggers inflammation and is one of the main causes of inflammatory arthritis. Both omega 3 fatty acids and omega 6 fatty acids are important essentials fatty acids that are necessary to the body for healthy functioning, but excessive omega 6 fatty acids are considered pro-inflammatory substance that enhances inflammation. Corn oil is loaded with omega 6 fatty acids, which promote the creation of eicosanoids – signalling molecules that promote systemic inflammation, leading to arthritis. Therefore, it is suggested to replace corn oil with omega 3 rich olive oil.


Coffee, one of the most preferred beverages also comes under the list of foods to avoid in an arthritis diet. Research shows that downing more than three cups of coffee per day leads to increased levels of C-Reactive Protein that is linked to inflammation and rheumatoid arthritis. Although health benefits of coffee are quite controversial and further research is needed to establish coffee as a potent risk factor in diabetes, it is best to substitute your cup of joe with nourishing green or black tea.


Alcohol is one of the vilest drinks for rheumatoid arthritis and gout. Excessive alcohol consumption weakens the liver, disrupts the functions of other organs and cause severe inflammation. It affects the joints and cause pain and swelling. Prolonged alcohol intake inflames the nerves, tissues and joints and cause pain the shoulders and chest. Heavy drinking leads to the formation of uric acid crystals in the joints which is one of the main causes of gout.

You can also consider fish oil supplements in the form of capsules if you are not a big fan of fish.

Leafy Greens – Dark leafy vegetables are a rich source of vitamin E, which protect the joints from cytokines or pro-inflammatory molecules.
