1. Mild products like rice, potatoes or toast
If you have a stomachache caused by a virus or if you constantly have to go to the toilet, it is best to eat mild products such as rice, potatoes and toast. These products do not weigh down your stomach if it is somewhat sensitive.
They also help against diarrhea by absorbing excess fluids and hardening your bowel movements. Choose whole-grain varieties to get extra fibre.
