Brandy from Seattle Washington sent in the following question. She asked can carrot juice give me an upset stomach or diarrhea? The answer is yes, drinking raw homemade carrot juice can give you an upset stomach or diarrhea. To reduce the chances of this occurring, you should drink carrot juice during or after a meal, so that it isn't as harsh on your stomach. I have also noticed that when I first started drinking raw homemade carrot juice, that it did give me diarrhea occasionally, however my system adapted to it, and I never have this problem anymore. Both fruit and vegetable juices can have quite a bit of natural organic acids in them, and without foods in your stomach to bind to, they can elevate the levels of acid within your stomach, and then cause it to flush through your digestive system. In conclusion, do drink the juice after you have some food in your stomach. Cheers, and have a great juicing day.
