There elimination diet it is an approach to nutrition that can be very useful for identifying cases of intolerance, sensitivity or allergies to certain foods. The scheme, valid ally when it comes to relieve symptoms such as abdominal bloating or constipation, it is very simple and is based on the fact of eliminating those foods that the body is suspected of having difficulty tolerating.
Subsequently, their progressive reintroduction and specific attention is paid to the symptoms that emerge following the intake. There elimination diet, characterized by a duration of between 5 and 6 weeks, is often used to improve the quality of life of people suffering from irritable bowels, intolerances or food allergies.
It is fundamental to specify that they exist different types of elimination diets (e.g. the FODMAP). Equally important is to point out that, if you have a known allergy or a more than concrete suspicion, it is crucial to focus on a specific path and carry it out under close supervision of your trusted dietician.
That said, let's move on to analyze the diet plan step by step. As mentioned earlier, we start with the elimination phase real, which lasts for 2/3 weeks. Among the foods that, depending on the situation, we proceed to eliminate include soy and its derivatives, dairy products, nuts, seafood, foods characterized by the presence of gluten (we have mentioned only some of the many examples that can be called into question). This phase is clearly very important, as it allows you to understand if the annoying symptoms are due to the removed food or other factors.
Once the first phase is archived, the time comes to proceed to the progressive reintroduction of eliminated foods. A piece of advice to follow is to proceed with the reinstatement by introducing each individual food group individually, paying attention to the onset of symptoms such as rashes, the aforementioned abdominal swelling and intestinal problems (just to name a few).
Returning for a moment to the characteristics of the elimination phase, you should dwell on the fact that the more foods you remove, the more likely you are to reach your goal. This implies, for example, proceeding with the temporary elimination of citrus fruits, legumes and starchy foods. When you follow one elimination diet attention should also be paid to fat quality that you bring to the table, trying to avoid butter and margarine. Not to be forgotten is also the importance of avoiding the intake of sugar, honey and maple syrup.
As regards instead i foods you can take, you have to include most of the fruits (except citrus fruits), herbal teas, le cow's milk substitute drinks (e.g. coconut milk), the turkey and lamb meat, game and fish such as salmon.
Science has repeatedly focused on the benefits of elimination diet. Among the many studies carried out it is possible to highlight a research work in 2006, led by an active team at the University of Kansas (USA). The experts in question have enrolled 20 individuals of both sexes and diagnosed with irritable bowel syndrome, a condition that can also cause abdominal bloating. The patients just mentioned, on whom standard therapies had not been effective, who underwent an elimination diet showed significant improvements related to some symptoms of IBS.
We conclude by reiterating that, before starting one elimination diet, it is essential to contact the attending physician and the dietician of your choice and follow their instructions in the best way.
