Hi, It is Possible for the food items to change stool colour drastically. If you had eaten lots of cashew nuts, lots enough that the digested cashew products form the major bulk of your stool, you could have pale stools or whitish stools. The other possible mechanism for pale stools is that there is obstruction of flow of bile into the intestine. However bile obstruction to cause very pale stools like in your case, it will have features of severe jaundice like darkening of urine and severe yellowing of eyes which is not there in your case. If you find any such features, plese report to a nearby doctor or else it can be just ignored. At the same time eating so much cashews at one go is also not a healthy diet as it is rich in cholesterol. Hope I have answered your question. Regards DR. Jeffrey
