It has often been observed that people get confused between Yams and Sweet potatoes and use these terms interchangeably, especially in stores where you buy them and in recipes; however, what you need to know is that these two vegetables are quite different in origin, taste, texture, and nutrition. This guide will provide you with a complete understanding of Yams and Sweet Potatoes, and how these two vegetables are different from one another. 

Introduction of Sweet Potatoes 

Scientifically known as Ipomoea batatas, sweet potatoes are root vegetables, which means they are present under the ground. The vegetable is native to Central and South America and widely cultivated all across the world. 

One of the biggest differences between Yams and sweet potatoes is that sweet potatoes have smooth skin and tapered ends. The flesh of this vegetable can be anything from orange and white to yellow and purple. The orange flesh is the most common variety, and these vegetables are rich in beta-carotene, which makes them a great source of Vitamin A. 

In the United States of America, the majority of ‘yams’ that are sold in supermarkets are sweet potatoes originally. These stores label the soft varieties as ‘yams’ to differentiate them from the firm and pale varieties of sweet potatoes. 

Overview of Yams 

True yams come from the genus Dioscorea. They’re starchy tubers, mostly found in Africa and Asia, and people in tropical regions rely on them as a staple. 

Yams really don’t look or taste like sweet potatoes at all. Their skin feels rough and almost bark-like, with some growing so big they can stretch several feet long and tip the scales at over 50 kilograms. Inside, the flesh can be white, purple, or reddish, and it’s a lot drier and starchier than what you get with sweet potatoes.

Flavor-wise, yams aren’t sweet. They’re more neutral, even earthy. People usually boil them, fry them, or pound them into dishes like fufu, especially in West Africa.

Main Differences between Yams and Sweet Potatoes 

Here’s a quick breakdown of the main differences between yams and sweet potatoes, so that you are free of your confusion of Yam vs sweet potato for once and all. 

• Family: Sweet potatoes belong to the morning glory family, whereas Yams belong to the Dioscoreaceae family, which makes them completely different. 
• Skin: Sweet potatoes have smooth skin. Yams? Rough and scaly.
• Taste: Sweet potatoes taste sweet and moist. Yams are dry and starchy.
• Where you’ll find them: Sweet potatoes are easy to find just about anywhere. True yams mostly show up in African, Caribbean, or Asian markets.

Nutritional comparison between Yams and Sweet potatoes 

Sweet potatoes are considered to be more nutrient-dense, especially the ones with the orange flesh. They are equipped with Vitamin A, fiber, and antioxidants. On the other hand, Yams are a good source of carbohydrates, fiber, potassium, and Vitamin C. 

If you are looking for a vegetable that is sweet and rich in Vitamin A, then sweet potatoes are the better option for you; however, if you like a more starchy and neutral base for dishes, then Yams are perfect for you.
