text: do foods such as tomatoes or red apples cause stools to have red spots/ streaks on them?? the reason why i ask this is that i have had at least two stools that i have noticed that part of them had red streaks on them ( not too many, just sporadically on a normally colored stool) , which caused me to get alarmed since it kind of made me think it was blood and they say that blood in stool can be a sign of colon cancer. of course i did eat tomatoes when the two cases of the red in the stools occured as well as a red apple with the skin, but i am still worried, even though when i wipe there is no blood on the toilet paper, nor is the water all bloodied, but i am still unsure, and i am thinking of seeing a doctor soon.....also the stools appear in many peices not just one whole one..my diet is also pretty healthy as i eat plenty of fruits and vegetables and low in red meat, and i am excercising and in pretty good shape....i am 18 by the way and no history of medical problems to date check with the doctor just incase, it could be just a tomato thing but it could also be something much more serious and just to ease your mind so you do not believe you are bleeding from different parts of your body everytime you ache (trust me, it is happened to me and i get all paranoid!).  a word to the wise :you can never be too cautious when it comes to the weird things in your stool ;-)
