This isn’t an article targeting squirrels! Believe it or not, people can eat acorns in the right conditions. These nuts come from oak trees and have a subtly nutty taste.

“As long as they are prepared correctly, acorns can be safe to eat and offer some health advantages,” says registered dietitian Trista Best, as reported by YSL News.

The crucial phrase here is “when prepared correctly.” Here’s what you should know about acorns before you try them.

Are Acorns Edible?

The quick answer is yes, humans can consume acorns. However, unlike the squirrels you might see munching on them, humans need to cook acorns before eating.

“Raw acorns contain tannins that make them unsuitable for raw consumption,” explains Best. “These tannins result in a bitter flavor, hinder nutrient absorption, and can be harmful in large quantities.”

Fortunately, tannins can be eliminated by boiling or soaking acorns in water, making them safe to eat, says Shelley Balls, a registered dietitian and nutritionist for Consumer Health Digest, as mentioned in YSL News.

Are Acorns Digestible?

Once acorns are properly prepared, they are generally easy on the digestive system, according to Best.

“They’re high in fiber, which can relieve constipation, but may lead to digestive issues for some individuals,” she cautions.

What Health Benefits Do Acorns Offer?

In summary, acorns are loaded with nutrients and antioxidants, says Balls. While you shouldn’t go overboard (think moderation), nutrition specialists believe they can be a valuable addition to your diet from time to time.

Acorns are abundant in vitamins, minerals, and nutrients that support heart, bone, and muscle health, as well as energy levels, metabolism, and brain function, according to Best. They are also advantageous for those following a low-glycemic diet since “acorns release energy gradually, aiding in blood sugar management and sustained energy.”

Furthermore, the fiber found in acorns contributes to “the growth of beneficial gut bacteria, promoting digestion and overall gut health,” she explains.
