Products Review Section

I would like to see a procucts review section of some sort to help us sort though the ingredient lists on products. For instance, if someone finds a certain product that they like and it works with their particular allergy, they can post it and the ingredients list, and then the product is listed on your site. We can click on “margarine” and we see what particular margarine would be safe for us.
It’s such a daunting task going to a grocery store for the first time and having to look at every ingredients list to try and find one that woeks for us. Having a place to start with here, would be wonderful.
Examples:
1. My son is allergic to canola oil, sunflower oil, peanut oil and cows milk. So far I have found one margarine that seems to be ok for him, but it took a long time, and a number of headaches having to read that fine print, finding it.
2. Soy milk has milk products in it. Some people wouldn’t know that if they didn’t look.
