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.
Avoid fried foods, greasy foods such as potato chips and spicy bagels or breads. Fruits and Vegetables If you have ulcers, eat fruits that are low in acid, such as apples, peaches, pears, grapes, kiwifruit, bananas, berries and melons. Avoid all citrus, as high-acid oranges, grapefruit, tangerines, lemons and limes may increase stomach acids. Consume vegetables that do not cause you pain, discomfort or excess gas.
