hi walrus.u r right...........food sensitivity means allergic to some food.but do you know that some people are sensitive towards particular foods and if by chance or owing to ignorance, if they happen to consume such food items, then it is likely that it might lead to fluid retention caused by inflammation and release of certain hormones, thus increasing their weight. In addition, there is fermentation of foods, particularly carbohydrates, in the intestines which can result in a swollen distended belly and gas production.
i hope now it"s clear to you .........
