Adherence to the following specific nutritional recommendations during illness:
In case of vomiting: as long as vomiting continues, the consumption of any food should be avoided. However, fluid loss should definitely be compensated. For this purpose, it is advisable to add liquids such as herbal teas (fennel, ginger, chamomile, peppermint and cumin tea) or water initially in small quantities, possibly by the spoonful. When vomiting has stopped, carbohydrate foods such as rusks, toast, and pretzel sticks are well tolerated at first. Meals should be small and eaten throughout the day. Stimulants should be avoided during vomiting and for a week afterwards.
For diarrhea: In the context of diarrhea, a “tea rusk diet” (duration: three days, longer if necessary; as long as no other diseases speak against it) has proven itself.
After the acute gastrointestinal disease, a light full diet is recommended. Within the framework of this diet, the following foods and preparation methods should be avoided, as experience has shown that they often cause discomfort:
Voluminous and fatty meals
Legumes and vegetables such as white cabbage, kale, peppers, sauerkraut, leeks, onions, savoy cabbage, mushrooms.
Raw stone and pome fruit
Fresh bread, wholemeal bread
Hard boiled eggs
Carbonated drinks
Fried, breaded, smoked, very spicy or very sweet foods.
