Around two to twenty percent of people globally suffers from a type of food intolerance. This means that food intolerances and sensitivities are rather common.
A gold standard used for decades to identify foods that people might be allergic too, or the foods people could be sensitive or having intolerances to, is the elimination diet. Although there are different types of elimination diets, the core of this diet works by eliminating some foods that are commonly known to cause uncomfortable symptoms and then later on bringing them back. Once the foods have been re-introduced, then the reactions will be monitored.
This eliminated diet can last for five to six weeks. During this time, the problems of gas, bloating, nausea, diarrhea and constipation could be alleviated. But the allergic reactions like rashes, problems breathing and swelling could also go away.
However, the key is to identify the foods that you might be allergic, sensitive or intolerant to. Thereafter, you can remove these foods from your diet to avoid any side effects. The foods that are causing the problem are called anaphylaxis.
How the elimination diet works
This diet is spilt into two phrases, namely the elimination and reintroduction.
The first phrase is the elimination phrase. During this phrase, you will be instructed to remove the foods that could be responsible for triggering the symptoms that is associated with an allergic reaction. You will eliminate these foods for a two to three week period. The common type of foods that are removed from the diet are nuts, corn, soy, dairy, wheat, gluten, pork, nightshade vegetables, citrus fruits, seafood and eggs.
If there are still problems then it might not been these foods. In that case, you will need to go back to your doctor to allow for other tests.
But once you have completed phrase one, then you will go on to phrase two – the reintroduction phrase. During this phrase, you will be instructed to bring back the foods that you have eliminated in the first phrase. More so, you need to bring the foods that was left out individually over a two to three week period. You need to monitor for any side effects. The side effects can range from rashes and skin problems, fatigue, joint pain, headaches, problems sleeping, bloating, breathing problems, bowel movement problems, and stomach pains. The idea is if you have none of these symptoms, then you can assume that you can introduce the next food group. If there are any side effects than you have identified that food group that you are sensitive too and should remove that from your diet.
In total, the elimination diet will take five to six weeks. But it should ideally be done with your doctor. That is since eliminating too many food groups may cause a nutritional deficiency.
