Sweet Potato VS Yam

Aren’t sweet potatoes the same thing as yams? No, they’re actually not and in this case, the perception is not the reality. The nutritional debate between sweet potatoes and yams, is characterized by misinformation, carbophobia, and baseless interpretation. As one of the most common nutritional misconceptions sweet potatoes are not the same thing as yams. We’re going to discuss the differences between sweet potatoes and yams, so you can decide which one you want in your diet.

Sweet Potatoes

Sweet potatoes are a sweet, starchy, and fibrous root vegetable. They come in a variety of oblong shapes and sizes, including orange, purple, white, and are rich in antioxidants, minerals, and fiber.

Sweet Potato Benefits

Sweet potatoes are rich in antioxidants, particularly beta-carotene which helps relegate free radical damage and oxidative stress. Free radicals have been linked to chronic disease states including cancer, heart disease, and diabetes. Including antioxidant rich foods in your diet, can help negate these harmful effects, and provide influential health benefits [R].

Beta-carotene is also very effective at raising blood plasma levels of Vitamin A. Vitamin A supports healthy vision and is used by the body to form light-detecting receptors in the eye [R].

Sweet potatoes are also rich in soluble and insoluble fiber, with nearly 7g per cup. Fiber is not absorbed and passes straight through your digestive tract, meaning that it will not spike blood glucose levels, like simple carbohydrates. More fiber in your diet, can help reduce your chances for heart disease, improve digestive health, fight obesity, and colon cancer [R, R]

Purple sweet potatoes are unique, and contain a powerful antioxidant called Anthocyanins. Animal studies have shown that Anthocyanins may improve memory and learning aptitude [R].

Yams

Often times mistaken for sweet potatoes, yams are a distinctly different species altogether. Yams are less sweet and more starchy than sweet potatoes. Yams have an exterior that resembles bark on a tree and an inside flesh which comes in a variety of different colors namely white, yellow, purple, or pink. One cup boats 5g of fiber, which also makes them a great source of fiber to improve digestive health and keeping you fuller for a longer period of time.

Yams Benefits

Like sweet potatoes, yams are a great complex carbohydrate and source of fiber. Yams are also a great source of B-Complex Vitamins, which have a direct impact on your energy levels, brain function, and cell metabolism. 92% of Americans have vitamin deficiencies, with B-Vitamins being one of the most common, therefore including yams in your diet, is a great way to increase your vitamins and micronutrients.
