Final answer:
A product loses its exemption from requiring a nutrition facts label if a nutrition claim is made about it.
Step-by-step explanation:
A product that was previously exempt from bearing a nutrition facts label loses this exemption if a nutrition claim is made about the product. This is because once a claim is made regarding the nutritional value or health benefits of a food item, it is mandatory under law to provide consumers with detailed nutritional information to substantiate that claim. Changes in package design, giveaways, or the nutritional value of the product itself (unless a claim is made) do not require the addition of a nutrition facts label.
