Hello there, Typhoid recurrs due to exposure to a contamnated source of water or due to eating non-vegetarian food like eggs, fish meat that is not prepared hygienically. You can have yoghurt and noodles but preferably home made. Also as you will have bouts of lethargy and tiredness-Coconut water, bananas are beneficial to get rid of the tiredness. You can also have a diet that includes plenty of fresh fruits and greens and take care of your protein intake. Buttermilk, curd, whey protein can be added to your diet. Avoid oily or heavy food as it will make you more lethargic. Precautions that you can take is always drink water that has been sterlised. Either boiled or filtered. If travelling carry your own water bottle or drink bottled water from known brands. Do not have roadside food or chaat or even salads from street vendors. Hope this helps, Please feel free to ask any further questions, I will be happy to answer them,
