Is chapathi and parata is good for peptic ulcers? also suggest having rice, ghee rice and chicken.

Not particularly but: Most peptic ulcers are caused by infection by H. pylori bacteria. While a bland diet may reduce stomach irritation it will not heal the infection nor the ulcer. While the conventional medical treatment is antibiotics, certain antimicrobial herbs can be effective. The best foods include cabbage, broccoli, ginger, garlic and turmeric.
