Whole Foods recently released its annual list of predicted healthy food trends for next year. Among the weird (cleaning supplies with probiotics) and the predictable (eco-conscious packaging), you’ll find the “marine munchies” category is still going strong in 2019. (That’s food made with the vegetable bounty of the sea.) Which means we’re all more than likely to be staring down more kelp noodles and seaweed-based after-school snacks this year. But what’s the difference between kelp and seaweed?

First, the similarities. Both are types of algae and are considered marine vegetables. Both are also incredibly nutritious, packed with vitamin A, calcium, iron, zinc, and iodine. Note, though, that both seaweed and kelp also have large amounts of iodine. Since too much iodine can negatively affect your thyroid, don’t plan on an excess of kelp-only smoothies.

The difference between the two are subtle. Most of us know seaweed from eating nori rolls. But seaweed is more than just those dry, crackly sheets of edible paper. The word “seaweed” is really a catch-all term that covers red, brown, and green varieties of this particular type of algae. It can grow in a number of marine-based environments such as lakes, rivers, and oceans, though it’s often mistaken as only saltwater-based.

If you’re interested in trying different types of seaweed, there are many varieties to choose from. In addition to the dark green nori (which is actually in the red seaweed family), it’s worth getting to know dulsi, also a red seaweed, and wakame, a type of brown varietal. Dulse is mostly eaten dried and its flavor is often compared to bacon. So, yes, go ahead and think of it like a healthier version of bacon. On the other hand, wakame has a bit of a sweeter flavor and when dried can be rehydrated to use in salads and other dishes.

Though kelp is also a type of seaweed, it grows only in saltwater environments, which is why it’s harvested near rocky ocean coastlines. Because kelp is so much bigger than other varieties of algae, it needs the continuous movement of the water to get its nutrients. Kelp also doesn’t float around like seaweed. It stays in a single spot due to a root-like system called a “holdfast” that anchors it to the ocean floor and allows groups of kelp to grow together. Little bags of air help the heavy stalks to float.

Kombu is the Japanese translation of kelp, so don’t fret if you see that word listed among the ingredients on the packaging of your new favorite snack. It’s also the primary ingredient in dashi, the broth used in many Japanese dishes. If you’ve had miso soup, you’ve tried kelp.
