Scottysgirl- I found a "cheat sheet" of sorts on a post from an IP alternatives blogger. It lists the following for selecting alternative IP items:
1. Minimum 12 grams protein.
2. Calories 70-160.
3. Restricted items have 9+ net carbs.
4. 30% or less calories from fat.
5. No aspartame.
Using these guidelines when ordering has been very helpful for me. I have been successful too. I follow along with all the same guidelines as my hubby who attends our local clinic, I just order my products from Nashua.
