How Much Protein Is in a Potato? Here's the Spud-Tacular Truth

Potatoes often get a bad rap for their high carbohydrate levels, but they're actually nutritional powerhouses.

While delicious, potatoes often get a bad (nutritional) rap. They're relatively high in calories and are packed with carbohydrates. But potatoes also have a number of nutritional benefits, including protein⁠. Protein is sometimes called the "building block" of all of our bodies' crucial components, from blood and tissue to muscle and bone.

Potatoes are also typically loaded with nutrients like vitamin C, fiber, potassium, and vitamin B6, according to research in Advances in Nutrition. Remember, though, that while potatoes are high in many nutrients, you might want to pair them with another source of protein, like meat or legumes, for a fully balanced meal.

Potatoes aren't typically thought of as a protein source, but as part of a balanced overall diet, you can certainly get a protein boost from this starchy staple. But just how much? Without further ado, let's dig more deeply into the amount of protein in potatoes, according to the United States Department of Agriculture's Food Composition Databases.

In addition to being high in vitamin C, vitamin B6, and fiber, sweet potatoes also contain choline, which helps to protect against inflammation, and beta-carotene, an antioxidant that gets converted to vitamin A in the body.
