What is Milk?

The Wall Street Journal has a story this morning about a debate taking place in the food industry over one simple question that apparently does not have a simple answer:

What, exactly, is milk?

Here’s how the Journal frames the story:

“Dairymen are lobbying Congress to restrict use of the word ‘milk’ to products derived from lactating animals like cows. Makers of increasingly popular soy, almond and coconut-based milk substitutes pushed back on Thursday, asking the U.S. Food and Drug Administration to back a broader use of the term.

“At stake is a $16 billion milk market where cows no longer stand alone. Sales of plant-based milk substitutes have soared 76% over the past five years while conventional milk sales dropped 18%, according to market research firm IRI.”
