Hullo! My mom and I are doing the whole 30 (day 13 currently), and we bought some fresh shrimp from the deli counter the other day. Problem is that it has "sodium polyphosphate" in it. I looked it up, and from what I saw I thought it was a preservative, so we tossed it in the freezer. But I then saw a post on the forums here about it, and someone else said it was compliant with the Whole 30. Some clarification would be great! (Also, any suggestions for nationwide shrimp brands that are all natural would be fab). Thanks!
