Often,
food labels claim that a product is fat free, low-fat, or
light. Because these terms can be confusing, the Food and
Drug Administration (FDA) has defined each one:
Fat
free-- The product has less than 0.5 grams of fat
per serving.
Low-fat-- The product has 3 grams or less of fat
per serving.
Reduced or less fat-- The product has at least
25 percent less fat per serving than the full-fat version.
Lite or light--
These terms can have a few meanings:
the product has fewer calories or half the fat of the
non-light version, or
the sodium content of a low-calorie, low-fat
food is 50 percent less than the non-light version,
or
a food is clearer in color (like light instead
of dark corn syrup).
Calorie
free-- The product has less than 5 calories per serving.
Low calorie-- The product has 40 calories or less
per serving.
Reduced or fewer calories-- The product has at least
25 percent fewer calories per serving than the non-reduced
version.
Make sure to read the Nutrition Facts Label to find out
how many calories are in a food.
