Why is it that if I take something from the grocery store with a bar code, scan it with MFP, the numbers I get are different than what’s printed on the package to begin with?
Anybody got a clue?
Thanks.

    Because the bar codes only pull up user-entered data which can be erroneous, vary by region, or simply outdated. Some bar codes have been recycled to new products so you may scan chips and get green beans.

    So the results of the scan are pretty much worthless? What’s with the green check marks by some foods, anyway.

    The green checkmarks stand for foods MFP has verified because they've received so many confirmations on the nutrition information, but they can still be wrong

    The bar code scanner is simply a "quick access" tool.

    Whether you scan or search, find an entry with a green check mark or not, you have to verify the numbers before using an entry for the first time.

    Scanning a bar code is the same as typing the product name into the search box, you just don't have to type.

    And you can't even fix them.

    At least the other incorrect info can be fixed.

    You could always just edit the information to match the package (assuming it isn't a verified entry). It takes less than five minutes.

    So when all is said and done, what information would you use to verify the nutritional information on a store bought product..what’s the bottom line?

    I go off the label. If it's a whole food, I verify against the usda database.

    For packaged items, the nutrition information on the package. For whole foods (fruits, vegetables, meat, etc.), the USDA's database
