The Federal Food, Drug, and Cosmetic Act preempted plaintiff’s claim that defendant’s label on “I Can’t Believe It’s Not Butter! Spray” misleadingly listed 0 calories and 0 grams of fat by using artificially small serving sizes.  The FDA sets serving sizes for labeling purposes by type of food product.  The Butter! Spray was a “spray” not “butter.”  And the label properly used the FDA-approved serving size for a spray.  Hence, the FDCA preempted plaintiff’s state law claims which challenged the label based on the FDA-approved serving size.
