In Cooperate with the BRAT Diet
The stomach flu can make it difficult for one to keep food down. It would help if you didn’t force yourself to eat when you do not feel like otherwise; you could end up throwing up the food. However, when you feel like eating, rather than just eating anything, you can just take that which could help relieve the sickness, the BRAT diet. BRAT stands for Banana, rice, applesauce, and toast. The reason for the recommendation of this diet is that these four foods are bland and binding, which makes them easy to digest and contain high-quality carbohydrates that help restore energy lost and replenish nutrients.
In the absence of the BRAT diet, you could still consume some other energy giving food. Just make sure to avoid fibrous foods, dairy, anything fatty or spicy, and anything greasy and salty.
