The 14 Healthiest Vegetables on Earth

12. Sweet Potatoes

Classified as a root vegetable, sweet potatoes stand out for their vibrant orange color, sweet taste and impressive health benefits.

One medium sweet potato contains 4 grams of fiber, 2 grams of protein and a good amount of vitamin C, vitamin B6, potassium and manganese (44).

It’s also high in a form of vitamin A called beta-carotene. In fact, one sweet potato fulfills 438% of your daily vitamin A needs (44).

Beta-carotene consumption has been linked to a significant decrease in the risk of certain types of cancer, including lung and breast cancer (4546).

Specific types of sweet potatoes may also contain additional benefits. For example, Caiapo is a type of white sweet potato that may have an anti-diabetic effect.

In one study, people with diabetes were given 4 grams of Caiapo daily over 12 weeks, leading to a reduction in both blood sugar and blood cholesterol levels (47).

Summary

Sweet potatoes are high in beta-carotene, which may decrease the risk of some types of cancer. White sweet potatoes could also help reduce blood cholesterol and blood sugar levels.
