If you are asking the question, it is probably the case. I don't know why, but it does seem that foods for which we have sensitivities are foods that we tend to over-consume. Peanuts can be very allergenic. (I have given them up for years because they give me horrible gas.) If you have a similar sensitivity, that could well explain your stool problem. I know when I find myself having that problem, it usually results from eating too much or too repeatedly of a problem food and it helps to cut down on whatever I am overdoing. I also address it by taking my fiber powder for 2 or 3 days. Combining these two approaches always restores a firmer stool for me.Mark
