While research has not determined that all people with fibromyalgia should avoid certain foods in order to manage their symptoms, some people experience a decrease in their inflammatory symptoms by eliminating certain foods from their diets, reports WebMD. Many people with fibromyalgia have food sensitivities, and the most triggering culprits are eggs, dairy, gluten, preservatives and other common allergens.
Sugar, alcohol and caffeine can also exacerbate fibromyalgia symptoms in people who are sensitive to those foods, according to Everyday Health. If a person with fibromyalgia believes her symptoms may be worsened by consuming particular foods, the site recommends using an elimination diet to determine which foods to avoid.
During an elimination diet, suspect foods are avoided entirely for seven days, states Everyday Health. On the eighth day, one particular type of food, such as wheat, is reintroduced to the diet. This is known as the challenge phase of the elimination diet because the person is challenging her body's ability to tolerate a food. If, after two days of a food's reintroduction to the diet, the person experiences no adverse symptoms or reactions, it is safe to conclude that the reintroduced food does not trigger symptoms. However, if the person experiences a worsening of symptoms after reintroducing a particular food, she may wish to eliminate that food from her diet in order to reduce symptom flare-ups.
Continue reintroducing foods until all suspect foods are tried. A week before starting the elimination diet and until its completion, keep a log of foods and symptoms in order to better understand any possible correlations between the two, recommends Everyday Health, which also recommends discussing any symptom changes, allergies or dietary changes with a health care provider.
