There are over 100 different types of autoimmune diseases. In a patient with an autoimmune disease, the body is unable to tell the difference between healthy cells and foreign cells. As a result, the immune system, which usually defends the body against disease, ends up attacking healthy cells. Some of the most common autoimmune diseases include arthritis, colitis, Crohn’s disease and lupus.

An autoimmune disease typically fluctuates between periods of remission with few symptoms, to flare-ups with worsening symptoms. Research has shown that diet plays a large role in preventing flare-ups.

Here are five foods that trigger autoimmune disease flare up’s:

1. Sugar

A diet full of processed sugar wreaks havoc on your body. It sabotages your immune system’s ability to handle illness, disease and other threats. Processed sugar weakens the immune system and causes inflammation, which can lead to an autoimmune disease flare up.

2. Quinoa

Quinoa is seen as a heath food thanks to its fiber, protein and iron content. However, for someone with an autoimmune disease, quinoa can be harmful. The saponins proteins in quinoa can cause damage to the lining of your gut, which causes your immune system to work in overdrive.

3. Gluten

Gluten can be dangerous for those suffering from an autoimmune disease. In a patient with an autoimmune disease, the body is unable to process gluten naturally. Consuming gluten puts stress on the immune system, which can result in a flare up.

4. Dairy

Even organic dairy can have a negative effect on the body. For those with an autoimmune disease, the casein protein naturally found in milk can cause inflammation in the body, which leads to a weakened immune system and an autoimmune disease flare up.

5. Milk Chocolate

Cocoa does have some pretty amazing health benefits. But if you suffer from an autoimmune disease, you’ll want to avoid milk chocolate. The fact that it’s a dairy product should help deter you from your cravings. Giving in can wreak havoc on your immune system.
