Food intolerances seem to be more common than ever. Nowadays, it is normal to hear about people who aren’t eating gluten or are staying away from dairy due to the negative effects they may have on the body. For some, it may be a food intolerance, and for others, it may be a food allergy, which is also a significant issue in the United States right now. 

According to Food Allergy Research and Education, over 33 million Americans suffer from food allergies. Symptoms range from mild, such as an itchy mouth and hives, to more severe, such as tightening of the throat. 

A food allergy is a reaction triggered by your immune system, whereas a food intolerance is an issue with your digestion.

Food intolerances are typically less severe, and you may still be able to eat small amounts of food without having serious problems. 

One way to determine what food intolerances you have is by doing an elimination diet. This diet has become massively popular, alongside the growth in issues with food intolerances. So how do you do it? 

Read on for all you need to know about the elimination diet. 

What is the elimination diet? 

The elimination diet is more of a food plan that has you get rid of foods that are common causes of allergies and intolerances, so that you can test and see how your body reacts to them, because each body is different. 

The severity of the elimination diet depends on the severity of your issues. Some people decide to simply eliminate gluten and dairy for a few weeks to see how they feel, while others do a more intensive elimination diet to help with more serious issues, such as IBS. 

Why should you do the elimination diet? 

If you find that you are suffering from physical symptoms, including:

• Bloating
• Gas
• Indigestion
• Immune system issues
• Brain fog
• Fatigue
• Headaches
• Acne
• Anxiety
• Mood swings
• Depression

You may want to give the elimination diet a try. You may be surprised to find that the root cause of your anxiety is not work-related, for example, but rather is the bread you eat every morning. 

How does the elimination diet work?

By eliminating certain foods from your diet for a period that may be triggering adverse responses in your body, you may find that your symptoms subside and you feel normal again. 

The elimination diet helps restore your microbiome and reduce inflammation.

Some research has found that it may help with issues such as IBS and leaky gut syndrome.

How do I start the elimination diet? 

Many people begin their elimination diet journey by cutting out the foods that are known allergens/intolerances for many people. 

These include:

• Dairy
• Gluten
• Soy
• Corn
• Refined sugar
• Peanuts
• Eggs

If you opt for a more intense elimination diet, you likely want to try eating a low FODMAP diet. This stands for Fructose, Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. Thus, some of the foods you will need to eliminate with this stricter elimination diet are:

• Nightshades (eggplant, tomatoes, peppers, white potatoes)
• High-fructose fruits (apples, cherries, mangoes, figs)
• Dairy products
• Legumes (beans, chickpeas, lentils)
• Garlic
• Onions
• Wheat products

These foods are considered short-chain carbohydrates, which means they are harder for your body to digest. 

How long does the elimination diet last?

This depends on your issues as well as the strictness of the elimination diet you choose to try.

Eliminating some of the key trigger foods may help you see results as soon as a few days after starting the diet. However, it may take a few weeks, maybe even months, for other people to see results. 

Therefore, you should continue the elimination diet until you notice a positive result.

A realistic place to start is aiming to do the diet for three weeks. At that point, evaluate and determine if you are ready to start reintroducing foods back into your diet. 

How do I reintroduce foods?

Once you feel that your body is doing better and you have cut out trigger foods for long enough, it is time to start bringing things back in. 

The best way to do this is by reintroducing just one food at a time. Take eggs, for example. Eat eggs once or twice over a few-day period and see how you feel.

It is essential to consume this food a few times within that period, as it may take a day for symptoms to appear. 

If the first reintroduction goes well, you can proceed to the next food. During the reintroduction period, you must pay close attention to how your body feels. Keep a journal of how each reintroduction goes.

What if I have a flare-up again following the reintroduction?

If you reintroduce a food and find that your body shows symptoms of intolerance, try eliminating it again for another two weeks and then bring it back in. If you keep trying this cycle and the food continues to bother you, then chances are good you have an allergy and will need to eliminate that food from your diet permanently. 

Conclusion

The elimination diet is worth a try.

It certainly won’t harm you and may only help with any food issues you’re experiencing. The key to success with this diet is patience, consistency, and being in tune with your body. It may take some time for you to see the effects of the elimination, but you must stick with the diet and listen to how your body feels.
