Question

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\?

Explanation:

"As Packaged" shows nutrients in the product as - sold, without preparation changes. "As Prepared" accounts for changes like adding water or cooking. Some products only have "As Packaged" if preparation doesn't significantly alter nutrients, or if they are ready - to - eat. Others have both when preparation can greatly change nutrient content.

Answer:

"As Packaged" gives nutrient info as - sold. "As Prepared" adjusts for preparation changes. Some products only have "As Packaged" when prep doesn't affect nutrients much or they are ready - to - eat; others have both when prep impacts nutrients.
