I can eat foods with natural sugars although not in excessive quantities. When I really have noticeable problems with sugar is when I eat desserts- ice cream, cakes, pies, cupcakes. My office tends to be very dessert-friendly especially when we celebrate someone’s birthday. There is usually one birthday or other office lunch a month and uniformly our office manager will order desserts and expect everyone to have a piece of whatever cake or pie or cupcakes get ordered. This is when I feel it and notice a palpable difference in my bowel function. It doesn’t kill me but I do notice a big difference. So what I do is generally behave carefully, and keep dessert and sugary foods to a minimum.
