You’ll throw praise-hands emojis up at Mother Nature for this one: A medium-sized baked potato contains three grams of protein, tons of vitamin C, potassium and some filling fiber, says Rust.
Potatoes are primarily made of carbohydrates and contain very little protein. This makes them an ideal diet for lean and thin people who desperately want to put on weight. The vitamin content includes vitamin C and B-complex, which also help in proper absorption of carbohydrates. That is one of the reasons that potatoes make up a large part of the diet of sumo wrestlers, as well as many other athletes who need large energy reserves in order to compete!
