I like. Jay Robb protein powders. He has whey, egg white and soy. They all have very simple ingredients and are sweetened with stevia. They come in Vanilla, Chocolate and strawberry. They are simple for the palate of kids and adults can add the extra ingrdients they may want. The label has a amino acid analysis.
I don't know if you are trying to raise tem as vegetarians (I saw kiwi in your user name). But, if you are I noticed there is now a pea protein powder at the HFS. I don't know the brand. But I am kind of curious about it.
My husband and I both typed our blood in high school as part of our biology classes. We both think we are O's but our son is A. So, one of us messed up. Tomorrow I am going in for a blood test. My alternative MD is sending the blood off to a place that will test 160 foods, etc. for allergies. She is going to type my bood in the office. I think I am o, if so I will look forward to reading up on here.
