Defined as an edible plant that grows underground, potatoes, carrots, and onions are a few common examples that most are familiar with.

However, there are many other types — each with a distinct set of nutrients and health benefits.

Here are the 13 healthiest root vegetables to add to your diet.

1. Onions

Onions are popular root vegetables, serving as a staple ingredient in many cuisines.

Antioxidants are compounds that can protect your cells against oxidative damage and help prevent disease.

Research shows that eating onions may be associated with a wide array of health benefits.

For instance, one study found that eating 3.5 ounces (100 grams) of raw onions per day significantly reduced blood sugar levels in people with diabetes.

What’s more, other research observed that onions may possess powerful anticancer properties, with observational studies linking a higher intake of this root vegetable to a lower risk of common types of cancer.

Onions work well in a variety of meals and can easily be added to salads, soups, scrambled eggs, casseroles, rice or pasta dishes, and many more.

They’re rich in fiber, vitamin C, manganese, and vitamin A and are a good source of several antioxidants — including beta-carotene, chlorogenic acid, and anthocyanins.

A review of three studies showed that eating 4 grams of white sweet potato extract each day for 12 weeks improved blood sugar control in people with diabetes.

Due to their vitamin A content, some studies suggest that this root vegetable may also improve immune function, protect against vision loss, and support skin health.

Sweet potatoes can be baked, boiled, roasted, or sautéed and enjoyed as a delicious side dish or added to everything from sandwiches to salads to breakfast bowls.

Adding vitamin C to your diet can help boost your immunity, with one study noting that getting enough of this vitamin could help reduce symptoms and shorten the severity of respiratory infections, such as the common cold.

Additionally, studies show that consuming more cruciferous vegetables, such as turnips, may be associated with a lower risk of stomach, breast, colorectal, and lung cancer.
