Once your child starts chemotherapy, at some point you find yourself studying the neutrophil count on every blood test result. There comes a stretch when that number drops sharply, and when it does, you can think of your child's defenses as nearly empty. A single germ that would normally pass without notice can make them seriously ill. So as a parent, the question "What can I feed them?" or "Is this one okay to give?" pops up several times a day. And when you go looking for answers, the information is all over the place, which only makes it more confusing.
To get to the point first: during this phase, there is really only one thing food has to protect against — keeping germs that might cling to undercooked or old food out of your child's mouth. That means every food is cooked all the way through and served while still warm. Whether it's meat, fish, or eggs, check that the center is fully done, and reheat anything that has cooled before serving it. Raw vegetable salads, sashimi, soft-cooked runny eggs, and fermented foods like kimchi are best set aside for now. For fruit, you'll feel more at ease choosing ones whose inside stays clean once you peel away a thick rind — like bananas or tangerines.
Two things that are surprisingly easy to overlook are dairy and nuts. Avoid unpasteurized raw milk and cheese made from it, and choose products labeled as sterilized. Nuts carry a risk of mold toxins, so during this phase it's safer to give them only in small amounts from individual packaging rather than from an open container — and only after checking with the medical team. Also, don't let opened food sit around. A side dish left at room temperature for two or three hours is better thrown out, however wasteful it feels. Germs multiply remarkably fast in warm, damp places.
Just as important as the food is the hands and utensils it passes through. Even the best-cooked porridge does no good if it's served with a dirty spoon. Wash your hands with a good lather of soap for about 30 seconds before and after cooking, and keep the cutting board and knife used for raw items separate from those used for cooked food. Make hand-washing before meals almost a ritual for your child, and switch to a soft toothbrush so the gums don't get nicked. When the lining of the mouth breaks down, germs can get in through it easily, so don't skip rinsing with water after meals or using a prescribed mouthwash.
Being this careful brings another worry: the diet becomes too monotonous. A child who has little appetite to begin with will turn away at the sight of plain white porridge. When that happens, vary things within the bounds of cooked ingredients. Stir finely grated sweet pumpkin into well-simmered rice gruel, or fold well-cooked chicken breast into mashed potato to make it soft. A warm broth-based dish tends to go down easily too. Serving small amounts often is better than forcing a full meal in one sitting. And if your child simply can't eat or develops a fever, that's past the stage where food can carry them through — let the hospital know right away.
