Rep. Peter Welch, D-Vt., is asking the Food and Drug Administration to enforce the definition of "milk" — as in, a beverage that comes from cows — and require non-dairy drinks that currently market themselves as "milk" to find another name. Welch argues that plant-based products using the name "milk" are freeloading off milk ads paid for by dairy farmers, such as the "Got Milk?" campaign.“You have these other products that are basically free-riding on the advertising about milk and its specific, positive qualities," Welch said in a telephone interview.The non-dairy milk products are misleading to consumers, Welch says, at a time when dairy farmers are struggling to make ends meet.
