Final answer:
People with peptic ulcers should avoid spicy foods and smoking to minimize symptoms and promote healing. These factors don't cause ulcers, which are mainly due to H. pylori infection or NSAID use, but they can aggravate the condition.
Step-by-step explanation:
Two things that people with peptic ulcers should avoid are spicy foods and smoking. While diet itself does not directly cause peptic ulcers, as they are primarily due to infection with Helicobacter pylori or chronic use of non-steroidal anti-inflammatory drugs (NSAIDs), certain foods and lifestyle habits can aggravate the condition. Spicy foods may increase discomfort by irritating the stomach lining, and smoking is believed to contribute to ulcer formation and interfere with the healing process.
The most common cause of peptic ulcers is Helicobacter pylori infection, and additional factors like NSAIDs, tobacco smoking, and stress may also play roles. The idea that dietary choices like spicy foods cause peptic ulcers is outdated, yet these may exacerbate symptoms in those already suffering from ulcers. Contrary to previous beliefs, coffee and dairy products do not have a significant impact on peptic ulcer development but may affect individual tolerance differently.
The correct answer is A) Spicy foods and smoking
