懷疑對某種食物過敏導致不適？試試“食物排除療法”吧。食物排除療法即把某種特定的食物從飲食中加以清除的治療方法。這是目前最精確、最可信的研究飲食反應的方法，但具體操作方法、時間可以因人而異。

An elimination diet is a method of identifying foods that an individual cannot consume without adverse effects. Adverse effects may be due to food allergy, food intolerance, other physiological mechanisms (such as metabolic or toxins), or a combination of these.
食物排除療法是確定一個人無法食用哪些會引發副作用的食物的一種辦法。這種副作用也許是因為食物過敏、食物不耐受、其他的生理機制（如新陳代謝或毒素）、或者以上因素綜合作用等問題。

Elimination diets typically involve entirely removing a suspected food from the diet for a period of time from two weeks to two months, and waiting to determine whether symptoms resolve during that time period.
食物排除療法常包括將可疑食物從飲食中完全清除一段時間（從兩周到兩個月），以等待確定在此期間癥狀是否緩解。

Common reasons for undertaking an elimination diet include suspected food allergies and suspected food intolerances. An elimination diet might remove one or more common foods, such as eggs or milk, or it might remove one or more minor or non-nutritive substances, such as artificial food colorings.
采用食物排除療法的常見原因有，懷疑食物過敏或食物不耐受。食物排除療法也許會排除一種或多種常見食物，比如雞蛋或牛奶，或者會排除一種或多種次要的或非營養性的物質，比如人工色素。

An elimination diet relies on trial and error to identify specific allergies and intolerances. Typically, if symptoms resolve after the removal of a food from the diet, then the food is reintroduced to see whether the symptoms reappear.
食物排除療法依靠試錯法來確定特定的食物過敏或不耐受。一般情況下，如果將某種食物從飲食中清除后癥狀緩解，之后這種食物還會被重新加入飲食中，以便觀察癥狀是否重現。
