It's a pretty common move among avocado eaters: You slice up the green part and chuck the seed in the trash. But one food blogger says we should rethink that habit.

In a new blog post and video that's gaining a lot of attention online, blogger Sophie Sonnenwirth of Nourish Me Whole argues that we should be eating the avocado seed in addition to the rest of the fruit (yup, avocados are technically a fruit). She even offers up tips on how to do it, although she acknowledges that avocado seed-eating is a "controversial topic."

But…why should we be eating the seed again? According to Sophie, the seed is the most nutrient-dense part of the avocado.

She's right, says Samuel Accardi, lead dietitian for health solution management company the Charge Group, who says he also eats the avocado seed. "The seed holds 70 percent of the avocado's antioxidants, which include the polyphenols that are found in green tea," he says.

Among the other perks of avocado seed-eating, per Accardi: The seed contains a lot of soluble fiber, which is great for the prevention of heart disease, and also may help with wrinkle prevention. "Studies have shown that avocado seed oil increases collagen in our skin, which makes it more elastic and less likely to wrinkle," Accardi says.

Luckily, you don't have to endure a Gobstopper-like situation to eat the seed. Instead, Accardi recommends letting it sit out for a few days to dry out. Once it's dried, cut it into quarters and put it into a high-powered blender or food processor to grind the seed into a powder. You can then add the powder to smoothies, yogurts, and oatmeal.
