Post op for my 2 weeks fluid, I struggled with soup cos it made me physically blegh (Im not a fan!)
So for me it was yoghurt without lumps thinned down to a consistency that goes up a straw,
skimmed milk
juice, fruit or veg but no lumps, bits or skins
~
Other things it suggested from my provider was
~ protein shakes
~ soya milk with added calcium
~ thinned soups with bits removed
~ actimel
~ vie or thin smoothie drinks
~ low cal hot chocolate, ovaltine, horlicks
~ oxo bovril or marmite with water
~ unlimited NAS squash, tea and coffee
