Almond milk has become a staple in most healthy households-and for good reason. It has more calcium that cow's milk and is a delicious dairy-free drink. But most of us assume that because ‘almond' is in the name, we're also reaping the heart healthy benefits of the nut. But a new lawsuit claims there may not actually be enough almonds in the drink to actually make that difference. (For more, see 13 Types of Milk That Do Your Body Good.)

Blue Diamond is being sued for falsely portraying that their widely popular almond milk, Almond Breeze, is made primarily from almonds when-the suers allege-the carton actually only contains two percent of the nut. That would make the majority of the milk alternative water, sugar, and a handful of additives like carrageenan, sunflower lechithin, and calcium carbonate. (Say what?

It's their phrasing, "made from real almonds," along with the copious amounts of almonds on the packaging that is misrepresenting the true recipe, the lawsuit claims. Blue Diamond doesn't actually disclose how much almond is in Almond Breeze sold in the U.S., but the website for their U.K. version blatantly states that the nut makes up just twp percent of the milk, a number the plaintiffs are working off of.

When a similar case came up in Great Britain in 2012 against a different almond milk brand, the U.K. Advertising Standards Authority said most shoppers understand almond milk requires a significant amount of water.

While this significant amount is pretty arbitrary, the new lawsuit doesn't actually specify what is acceptable either. They do note that the "vast majority of the recipes [on the internet] call for one part almond and three or four parts water, amounting to 25-33 percent of almonds."
