Explain the difference between the columns commonly found on nutrition labels called "as packaged" and "as prepared." why do some products have both and others only have "as packaged"?

"As Packaged" refers to how the nutritional content of the food is marketed, and "As Prepared" refers to the nutritional content of the food when it's ready for consumption.

Explanation:

The "As Packaged" column is just a measure of the raw components in a box or processed item.

The "As Prepared" column attempts to take these added nutritional sources into account.
