Your doctor and a dietitian are great resources to help you figure out what foods work best for you. Keep them in the loop on how you feel and what you eat. They can answer your questions and help you get the nutrition you need. If you can't eat a balanced diet, you might need to take supplements like calcium, folic acid, and vitamin B12. Ask your doctor if they should be part of your plan. You may find that you do better with smaller meals throughout the day instead of three big ones. When you make your diet plan, think about foods that you can carry with you for healthy snacks.
