With health food and juicing being trendier than ever (yay!), it’s now easier than ever to find cold-pressed, organic, and natural juice products on the shelves of places like Target, Costco, Starbucks, and even Walmart.

But buyer, be wary: what’s in your juice? Before you grab green, read the label. Just because it looks healthy doesn’t mean it is healthy. Granted, there’s no harm in putting fruits and vegetables in your body — we’re big advocates of that. But if you’re monitoring your sugar intake, you may want to take a closer look at nutrition information before cracking open a to-go bottle of greens.

A big factor to look out for? Apple juice. Many prepackaged green juices use it as a base, and it’s super high in sugar. Some of these green drinks will have as much (if not significantly more) sugar as a can of Coke. Seriously. While fruit juice is definitely better than high fructose corn syrup, it’s still important to educate yourself and be mindful of what you’re consuming. Here’s a quick guide to four staple brands you can find in most store shelves: Naked, Suja, Odwalla, and Evolution Fresh.
