Should you be excited about the new McDonald’s “kale burger?”

Last year, McDonald’s debuted its first-ever kale salad—which, in theory, was a great thing.

In reality, though, the salad packed a whopping 730 calories and 1,400 milligrams of salt—proving that just because something sounds healthy doesn’t mean it’s actually good for you.

Now, Mickey D’s is back on the kale-wagon, offering up another attempt at a fresh, healthy, millennial-motivated option.

But before you bow down to McDonald’s and order a Signature Sriracha, consider that the sandwich isn’t quite a glorified kale burger.

Meet the Signature Sriracha sandwich, which is “freshly prepared” and comes with not just a beef, grilled chicken, or crispy chicken patty and special Sriracha Big Mac Sauce, but also—gasp!—baby spinach and baby kale.

“McDonald’s is taking a different approach to lettuce by adding premium greens to its signature sandwiches,” the company says on its website. “Baby kale and baby spinach were chosen specifically to balance out the spicy sauce while serving as the perfect partner to accompany the other savory ingredients of white cheddar cheese, onions, and tomato.”

But before you bow down to McDonald’s and order up a Signature Sriracha, consider that the sandwich isn’t quite a glorified kale burger. The sammy weighs in at 670 calories, 1,010 milligrams of salt, and 35 grams of fat. It’s also served with cheddar cheese, and the “onions” the company mentions are actually crispy (aka fried) onions. It’s a behemoth of a burger—but it’s actually healthier by the numbers than the aforementioned kale—er, fail—salad.

The Signature Sriracha is available now (for a limited time) in Seattle, San Diego, and Los Angeles.

Overall, the kale-topped burger is another step in a positive direction for the fast food industry. (And we’ll take kale and spinach over yoga mat chemicals any day!) But, as with everything from face serums to grocery items, it’s worth taking a close look at the ingredients list to know what you’re really getting.

Defining “healthy” can be confusing. These documentaries help break it down, and here’s what to know about celebrities who endorse “healthy” products.
