After diarrhea symptoms have subsided, stick to this schedule for reintroducing foods.
Day 1
Continue eating simple foods such as bananas, rice, applesauce, and toast, and reintroduce protein and prebiotic foods during breakfast. At lunch and dinner, continue to up your protein intake while also re-introducing some simple carbohydrates. Make sure to stay hydrated, drinking plenty of water (and low-sugar sports drinks, if desired) throughout the day.
For example, you can add some scrambled or hard-boiled eggs and yogurt to your breakfast. You could also try plain rice cakes or rice cereal (with just a small amount of low-fat milk.) At this point, do not add back in any other dairy.
For lunch, try adding some canned tuna or lean turkey breast to your meal, along with pretzels or plain pasta. Continue to keep carbohydrates simple, avoiding whole grains. For dinner, try a soup made from chicken broth, a small portion of chicken, carrots, mushrooms, peeled zucchini, and green beans.
Day 2
Continue avoiding spicy, fatty, and fried foods, and continue reintroducing more proteins, carbohydrates, and vegetables to your diet. Keep carbohydrates simple, avoiding whole grain bread and brown rice. Don’t reintroduce milk, cheese, and butter to your diet yet.
At breakfast, try making a green smoothie with banana, spinach, and berries (and a splash of almond milk or juice). For lunch, have some grilled chicken breast on white bread or with white pasta, served with a side salad. At dinner you can have some baked tilapia with white rice and asparagus.
Day 3
Now’s the time to start reintroducing complex carbohydrates to your diet. Instead of white bread, you can have wheat bread with some butter for your morning toast. It’s okay to start consuming dairy again as well. You should be able to eat all of the high-fiber foods you normally enjoy, such as beans, cruciferous veggies, and whole grains. Make sure to stay hydrated and get plenty of protein as well.
Day 4 and Beyond
You should be back to your regular eating routine.
