Open Food Facts invented a collaborative scanning app in 2012, which has been completely upgraded. (For Apple and PC.)
Just downloaded it. I will grab some stuff already in my pantry and give it a whirl.
AUGH! It warns about saturated fat, and fat. Crikey. Though restricting fat when there is plenty on your body already is a sensible weight loss strategy. Especially if we want people to emphasize protein, which we do. (Honestly, I constantly forget how LITTLE most people understand
food.)
I can choose Food Preferences. Rank food, see the info I care about first, and get a compatibility summary. That's versatile.
Nutri-Score for good nutritional quality, salt in low quantity, sugars in low quantity. I just set my food processing info to be Very Important. Organic farming and fair trade are important to me. And I can set allergens! Gluten, without nuts (HIGH oxalate), no soy, etc.
So I just scanned a package of organic freeze-dried strawberries, my emergency fruit for smoothies. (Makes it nice and thick without binders!) I'm told this has very good nutritional quality, low environmental impact, and does not contain gluten, peanuts, or soy. I can compare the category with fresh or frozen versions.
And I signed up to share what I scan if it is not in the database already.
The added salt in my Wild Herring Fillets makes it category 3. Still good
