Market Fresh Finds: Yams are tubers to satisfy a sweet tooth


People are often understandably confused about the difference between yams and sweet potatoes.

Real yams are native to Africa and Asia. While you may find real yams in your grocery store, you’re not as likely to see them at your local farmers market. However, you may find sweet potatoes labeled as yams. Compared to real yams, sweet potatoes are sweeter and softer, and are what most people in the United States eat for Thanksgiving dinner.

Here’s the tricky part: There are typically two types of sweet potatoes sold locally. One type has golden skin and paler flesh. It is always labeled as a sweet potato. The second type has coppery skin and orangey flesh. It is sometimes labeled as a sweet potato, and sometimes labeled as a yam. This is the type of sweet potato I’m referring to in this article.

Sweet potatoes are nutritious and filling. They are an excellent source of vitamin C, potassium, and beta carotene thanks to their orange flesh. Beta carotene helps to promote healthy skin, eyes and immune system. Sweet potatoes are also a good source of fiber. A diet high in fiber helps you feel fuller throughout the day, promotes a healthy gut, and is associated with a lower risk for diabetes.

To take advantage of all the health benefits sweet potatoes have to offer, buy them when they are in peak season in the fall. Choose sweet potatoes that are firm with smooth skin, and free of dents or blemishes. Look for small to medium sweet potatoes, as larger sweet potatoes tend to be starchier.

Sweet potatoes can be stored for up to five weeks in a cool, dry place. To keep them longer, you can freeze them or preserve them in cubes using a pressure canner.

Sweet potatoes are versatile. They can be baked, boiled, steamed, sauteed, roasted, fried, grilled and even eaten raw. They’re good in soups, salads, casseroles, on sandwiches and on their own. They can be served up as a side dish or as the star of the show. Here are a few suggestions for including sweet potatoes in your diet:

• Bake a sweet potato as you would a regular potato and top with your favorite toppings. Popular combinations include brown sugar, cinnamon, butter and salt, or maple syrup, butter and toasted pecans.

• Cut raw sweet potatoes into 1/4 -inch slices and pop into the toaster. Top with avocado, almond butter or whatever else sounds good to you.

• Toss them in your salad, raw or roasted. They’re good with toasted walnuts, pecans or cashews.

• Puree cooked sweet potatoes with bananas, maple syrup and cinnamon. Top with walnuts.

Whether you call them yams or sweet potatoes, there are lots of options for including them in a healthy, balanced diet that go beyond Thanksgiving dinner.
