Cell phones are a tool for communication. If used properly and with some parameters for a students (time, length of calls, texting), the cell phone would not prevent a student from making good grades. If the student is constantly on the phone and not attending to business, the problem is not the cell phone but behavior.
A food that can help treat a stomach ulcer is cranberries. Cranberries are rich in flavonoids, nutrients that can reduce the growth of H. pylori, the bacteria responsible for ulcers and accelerate healing. Other foods that contain flavonoids include celery, cranberry juice, onions, garlic and green tea. Avoid any foods that cause stomach discomfort.
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.
