Ask the dietician attached to the surgical team for a meal plan. and stick to the level she suggests. so free fluids first, then the next level. then soft food - I had low calorie jellies ready and pureed fruit (baby puree level). For me she suggested that I get in plain yoghurt as she knew I liked it. and eat protein first. my protein was mainly chicken, fish, eggs, and cottage cheese.
But my greatest help was fresh unsweetened pineapple juice, to sip. It helped rid me of all the foamy mucous phlegm that was making life a misery for the first three weeks at home. Fresh pineapple juice really saved the day. My Doctor suggested it and it worked a treat after three hours of sipping it , a little at a time, I finally gained relief from all the vomiting of foamy phlegm.
Here is why - fresh pineapples contain digestive a digestive enzyme in them called, "Bromelain".
Bromelain helps break down hard to digest proteins in our digestive tract naturally so we do not end up with gas, bloating, nausea, upset stomach, diarrhea, burping or constipation. - enzyme bromelain is known to reduce phlegm and mucus in throat
