When adrenaline rushes through your body, your blood goes to the places that your body feels need it most. That means that your blood is rushing to your heart, your brain, and possibly various muscles, and to do that it rushes out of your legs and makes them feel more like jelly.
Since acid is a primary cause of ulcers, you want to completely avoid any foods with high acidic content. Among them: alcohol, black and red peppers, chili powder and hot peppers, all of which irritate the stomach lining, and coffee, tea, colas, or chocolate, which can increase the amount of stomach acid.
If your stomach ulcer is caused by an H. pylori infection, foods that are rich in antioxidants may be beneficial. They could help protect and activate your immune system and help fight the infection. They may also help protect against stomach cancer. Foods like blueberries, cherries, and bell peppers are packed with antioxidant power.
