My wife has gastroenteritis what can she eat? i have some turnip green in the cabinet...

Not best: Although she may tolerate turnip greens this is probably not the best approach. Would make sure she is well hydrated with lots of fluids, and if she is well enough to eat, use bland dietary items which are soft and easily digested.

Aovid the greens.: Start w clear liquid like water, slightly flattened soda that is clear, or sports hydration drinks. Sip, sip, sip. Work up to solids w bland foods like bananas, rice, applesauce, toast, gelatin, or chicken. Avoid alcohol, nicotine, caffeine, dairy & high fat foods. Rest.
