I have ibs and scared its cancer or a disease it's getting worse. is it good to make natural vegetable and fruit juices for antioxidants vitamins ?

Not the key: After decades of work, I know on physician personally who takes antioxidants with the idea that they will improve health or longevity; there may be some here. Inflammatory bowel disease requires extra cancer surveillance and your physician needs to explain this to you. Food choices aren't the key to managing your illness; a holistically-minded evidence-based physician might be a good ally.
