Department of Agriculture requires labels with the term 'yam' to be accompanied by the term 'sweet potato.' Unless you specifically search for yams, usually found in an international market, you are probably eating sweet potatoes, the Library of Congress states. More likely than not, when you are shopping at a regular grocery store, the 'yam' you see is actually a sweet potato. Yams are native to Africa and Asia. Nearly 54 million tons of yams are farmed in sub-Saharan Africa, known as the "yam belt." It produces 95 percent of the world's yams, the USDA says. In America, where there were no yams, they were replaced with the New World sweet potatoes (Ipomea batatas), which were paler in color and drier in texture than.
Sweet Potatoes, often called 'yams,' are a dicot (a plant having two embryonic seed leaves) and are from the Convolvulaceae or morning glory family. Neither yams or sweet potatoes are a particularly rich source of protein, a nutrient necessary for muscle building and tissue repair.
#YAMS VS SWEET POTATOES SKIN#
Sweet potatoes are more moist and sweet than a yam, and can come in a variety of colors with red or light skin and orange or white flesh. The confusion all started when the orange-fleshed variety of sweet potatoes was introduced to the United States in the 1930s. Even though they are completely different vegetables, yams and sweet potatoes get lumped together because of bad marketing. They come from the morning glory family instead of the nightshade family. This includes canned yams and candied yams, which are all made from sweet potatoes. Yam is an amazing low-calorie treat, especially for those canines who are trying to lose weight. Raw yams are generally not recommended because they can be harder to eat and digest. Just like sweet potatoes, cooked yams are also safe and healthy for dogs. And if you like them or not, the age-old question remains – What is the difference between a yam a sweet potato?Īccording to the Library of Congress, although yams and sweet potatoes are both angiosperms (flowering plants), they are not related botanically. Yams are a monocot (a plant having one embryonic seed leaf) from the Dioscoreaceae or Yam family. Although sweet potatoes live up to their name when it comes to their sugary flavor, theyre not actual potatoes. Yams are less sugary (more starchy) than sweet potatoes and have a much drier texture.
