Acorns aren't just for squirrels, but read this before eating them yourself

No, this isn't an article written for (or by) squirrels – humans can actually eat acorns under certain circumstances. The nuts stem from oak trees, and can actually elicit a mild, nutty flavor.

"Acorns can certainly be safe to consume, when prepared properly, and have some health benefits," registered dietitian Trista Best tells USA TODAY.

The key words are "when prepared properly." Here's what to know about acorns before you go nuts trying them for yourself.

Can you eat acorns?

The short answer is yes, humans can eat acorns. But unlike the squirrels you may see chowing down on one outside, humans need acorns to be cooked prior to consumption.

"Raw acorns contains tannins, which make them unsafe to eat raw," Best explains. "They cause a bitter taste, interfere with the absorption of other nutrients and can be toxic in high amounts."

The good news: Those tannins can be removed by boiling or soaking acorns in water, which then makes them safe to eat, Shelley Balls, a registered dietitian and nutritionist for Consumer Health Digest, tells USA TODAY.

Yes, walnuts are good for you. But people with this medical condition should avoid them.

Can you digest an acorn?

After properly preparing acorns, they're usually pretty gentle on the digestive system, Best says.

"They contain a significant amount of fiber, which can help with constipation, but could cause digestive discomfort in those sensitive," she adds.

What are the health benefits of acorns?

In short, acorns are packed with nutrients and antioxidants, Balls says. Don't get too carried away (read: consume in moderation), but nutrition experts say they can be a helpful addition to your diet occasionally.

Acorns are rich in vitamins, nutrients and minerals that help to support heart, bone and muscle health, as well as energy, metabolism and brain function, according to Best. They're also beneficial for those on a low-glycemic diet, because "acorns release energy slowly, which aids in blood sugar regulation and sustained energy."

The fiber in acorns also helps to "support the growth of good gut bacteria, aiding digestion and gut health," she adds.
