Is There a Link Between Autoimmune Disease and Your Diet?

Autoimmune diseases are a group of conditions where the body's immune system mistakenly attacks healthy cells and tissues. There are over 80 different autoimmune diseases, including rheumatoid arthritis, lupus, multiple sclerosis, and type 1 diabetes.

While the exact cause is unknown, research suggests that diet may play a role in the development and management of these conditions. Certain foods may trigger symptoms or worsen the condition, while others may help manage symptoms and reduce inflammation in the body. 

Which foods to avoid:

Inflammation is a natural process that helps the body fight infection and heal injuries. However, chronic inflammation can damage cells and tissues, and increase the risk of developing chronic diseases. Foods that can trigger or worsen inflammation in the body include:

Highly processed foods:

Highly processed foods can increase intestinal permeability, which can allow antigens and pathogens to pass out of the gut and into the bloodstream. These include foods that have a long shelf life and are made in a factory such as: chips, cookies, crackers, and sweets. Fast foods such as burgers, french fries, pizza, and fried chicken. Breakfast cereals: These often contain added sugar, artificial flavours, and colours. Fizzy and sugary drinks including sports drinks, and energy drinks.

Salt:

Salt appears to increase levels of immune cells involved in inflammation and autoimmunity. Take special caution when it comes to frozen meals and canned foods, these often contain high levels of sodium and unhealthy fats.

Can you “reset” your immune system?

While diet alone cannot cure autoimmune diseases, research suggests that it may play a role in managing symptoms and reducing inflammation in the body.

Several foods are worth trying:

• Whole plant foods contain phytonutrients that can act as antioxidants and exert anti-inflammatory effects, which may reduce autoimmune symptoms.
• Plants are naturally anti-inflammatory and high in fiber, and they contain none of the additives found in highly processed foods.
• Using turmeric and ginger to flavour meals can offer additional anti-inflammatory activity.
• Diets that mimic fasting show some promise for suppressing autoimmune responses and fighting inflammation.
• Ensuring adequate vitamin D and omega-3 intake is equated with lower autoimmune disease risk and fewer symptoms.
• Promoting gut health with high-fiber plant foods and probiotics can reduce inflammation in the gut, prevent permeability, and increase short-chain fatty acid production to support healthier immune responses.

• Choose lean protein sources such as fish, chicken, and beans.
• Cook with healthy fats such as olive oil, avocado oil, and nuts.
• Fill your plate with fruits, vegetables, and whole grains.
• Drink plenty of water.

If you experience any symptoms of an autoimmune disease, it is important to see a healthcare provider for an accurate diagnosis and to discuss any dietary changes that may be helpful. Read food labels carefully and avoiding processed foods that contain added sugar, unhealthy fats, and artificial ingredients can be useful to help reduce the inflammation and keep the chronic symptoms under control.
