Sweet Potato vs Yam and their Benefits || Healthy Eats

Hello Beautiful People !

As a Chinese, I grew up eating sweet potatoes as dessert, as a meal, as a snack. It shocks me that I know so little of this amazing food. SO what are the difference and have we been buying the wrong stuff all along ?

What's a Sweet Potato?

There are many varieties of sweet potatoes, which come from the morning glory family. Skin color can range from white and yellow to red, purple and brown, while the flesh can be white, yellow, orange or even orange-red. These vegetables have an elongated shape with tapered ends.

Among the numerous varieties of sweet potatoes grown in the U.S. there are two major types:

Firm sweet potatoes, which have golden skin and paler flesh.
Soft sweet potatoes, which have copper skin and orange flesh.
The two types of sweet potatoes cook differently. After cooking firm sweet potatoes still remain firm and a little waxy, while the soft variety becomes creamy, fluffy, and moist.

What's a Yam?

Yams have a cylindrical shape with blackish or brown, bark-like skin and white, purple or reddish flesh. Compared to sweet potatoes, yams are starchier and drier. True yams can be tough to find.
