Sometimes you will see foods entered by other members in the tracker, and those members may have made an error when entering. With SparkPeople entries, the reason that manufacturer's food items sometimes differ from what you see in the tracker is because sometimes they change their formulations and the values change faster than we can keep the database updated. Other times, they have their foods re-analyzed and discover they need to change their labels as a result. Also, there can sometimes regional differences in available products that lead to different values.
