O ver the past decade, non-dairy milks have soared in popularity. Part of this is because of concerns about the climate crisis: the dairy industry is uniquely bad for the environment in part because of the amount of methane cattle produce. But many have also switched to non-dairy citing concerns about cruelty to animals, an exploration of veganism, an increasing awareness of lactose intolerance, concerns about fat and sugar and even worries about good skin.

“I have an Aldi and Lidl by me,” says Su-Jit Lin, a food writer in Atlanta, “and that milk can go as low as $1.25 for a half-gallon. So why not get a half-gallon of dairy milk when almond milks are $3 and change?”
Bon Appétit found that the cheapest whole dairy milk at supermarkets was two cents an ounce at Walmart, while almond milk cost four cents and oat six cents.
