TrueJoy,
I like Dr. Mercola's Pro-Optimal Whey Protein, it comes in 3 different flavours, my favorite is chocolate. The reason I like his is they are the best, they have no junk or sugars in them, come from grass fed and no hormone cows. And they already contain digestive enzymes in it, so it makes it easy to digest. I have 2 of these shakes a day - you can see from my sig what I put in my shake.
The almond milk I use is Almond Dream.
I think making good quality whey protein shakes is a good way to ensure that you get the nutrition your body needs. Also, one big plus is that since it is liquid nutrition it isn't hard on the gut, and you stomach doesn't have to "work" to break anything down. So, imo, it gives you gut a rest, whilst giving you the nutrition you require.
I hope you start to feel better soon.
