The terms “sweet potatoes” and “yams” are often used interchangeably in the United States, but technically, they refer to different types of root vegetables. This confusion has led to a long-standing debate about the correct terminology. In this article, we will delve into the history, cultural influences, and marketing strategies that have contributed to the widespread use of the term “yam” to describe sweet potatoes in America.
A Brief History of Sweet Potatoes and Yams
To understand the origin of the confusion, it’s essential to explore the history of both sweet potatoes and yams.
The Sweet Potato: A Native American Staple
Sweet potatoes (Ipomoea batatas) are native to the Americas, specifically the tropical regions of Central and South America. They were a staple crop for many Native American tribes, who cultivated and consumed them for centuries. Sweet potatoes were introduced to Europe by Spanish explorers in the 16th century and later became a popular crop in Africa, Asia, and the Pacific Islands.
The Yam: A Tropical African and Asian Root
Yams (Dioscorea spp.), on the other hand, are native to Africa and Asia. They belong to a different genus and species than sweet potatoes. Yams are starchy, dry, and often rough-skinned, with a white, yellow, or purple flesh. They are a staple food in many tropical regions, particularly in West Africa and the Caribbean.
The Louisiana Connection: How Yams Became Sweet Potatoes
So, how did the term “yam” become associated with sweet potatoes in the United States? The answer lies in the history of Louisiana, particularly in the city of New Orleans.
The Influence of African and French Cultures
During the 18th and 19th centuries, enslaved Africans were brought to Louisiana, where they were forced to work on plantations. These Africans brought with them their knowledge of yams, which they had cultivated and consumed in their homeland. However, the climate and soil conditions in Louisiana were not suitable for growing yams, so they adapted by cultivating sweet potatoes instead.
French colonizers, who had established trade relationships with Africa and the Caribbean, also played a significant role in introducing the term “yam” to Louisiana. In French, the word “igname” refers to both yams and sweet potatoes. This linguistic overlap contributed to the confusion between the two terms.
The Rise of the Louisiana Sweet Potato Industry
In the late 19th and early 20th centuries, Louisiana became a major producer of sweet potatoes. The state’s fertile soil, mild climate, and abundant water supply made it an ideal location for growing sweet potatoes. The Louisiana sweet potato industry thrived, and the term “yam” became a marketing tool to differentiate their product from other sweet potatoes grown in the United States.
Marketing and Advertising: The Yam Myth Takes Hold
The widespread use of the term “yam” to describe sweet potatoes in the United States can be attributed, in part, to marketing and advertising efforts.
The Louisiana Sweet Potato Commission
In the 1930s, the Louisiana Sweet Potato Commission was established to promote the state’s sweet potato industry. The commission launched a successful marketing campaign that emphasized the unique characteristics of Louisiana sweet potatoes, which they referred to as “yams.” This campaign helped to create a distinct identity for Louisiana sweet potatoes and further solidified the use of the term “yam” in American culture.
Supermarkets and Food Retailers
Supermarkets and food retailers also played a significant role in perpetuating the “yam” myth. To differentiate their products and make them more appealing to consumers, many retailers began labeling sweet potatoes as “yams.” This labeling was often accompanied by marketing campaigns that emphasized the supposed unique characteristics of “yams,” such as their sweetness and nutritional value.
Culinary and Cultural Significance
The use of the term “yam” to describe sweet potatoes has also been influenced by culinary and cultural factors.
Southern Cuisine and the Yam Tradition
In the Southern United States, sweet potatoes have long been a staple ingredient in traditional cuisine. The term “yam” has become an integral part of this culinary heritage, particularly during the holidays. Sweet potato dishes, such as candied yams and yam casserole, are popular side dishes during Thanksgiving and Christmas.
African American Culture and the Yam Connection
The use of the term “yam” also has cultural significance in African American communities. In some African American traditions, yams are seen as a symbol of African heritage and cultural identity. The use of the term “yam” to describe sweet potatoes serves as a connection to this cultural heritage.
Conclusion
The widespread use of the term “yam” to describe sweet potatoes in the United States is a complex phenomenon that has been shaped by history, cultural influences, marketing strategies, and culinary traditions. While technically incorrect, the term “yam” has become an integral part of American culture and cuisine.
In conclusion, the next time you’re at the supermarket or a restaurant, and you see “yams” on the label or menu, remember that you’re likely looking at sweet potatoes. However, also appreciate the rich cultural heritage and history behind the term “yam,” which has become an enduring part of American culinary tradition.

What is the difference between sweet potatoes and yams?
Sweet potatoes and yams are two distinct types of root vegetables that are often confused with each other. Sweet potatoes belong to the Convolvulaceae family and are native to the Americas. They are characterized by their sweet, soft flesh and are typically orange in color, although they can also be found in yellow, white, and purple varieties. On the other hand, yams belong to the Dioscoreaceae family and are native to Africa and Asia. They are generally starchier and drier than sweet potatoes, with a rough, scaly skin that is often brown or black in color.
Despite their differences, sweet potatoes and yams are often used interchangeably in American cuisine, particularly in the Southern United States. This confusion is largely due to a historical mistake, which will be discussed in more detail below. However, it’s worth noting that true yams are not commonly found in most American supermarkets, and what is often labeled as a “yam” is actually a sweet potato.
Why do Americans call sweet potatoes yams?
The confusion between sweet potatoes and yams in the United States dates back to the 1930s, when Louisiana farmers began marketing their sweet potatoes as “yams” to differentiate them from other sweet potatoes grown in other parts of the country.

By labeling their sweet potatoes as “yams,” Louisiana farmers were able to charge a higher price for their product and create a distinct brand identity.
Over time, the term “yam” became widely used in American cuisine to refer to sweet potatoes, particularly in the Southern United States. Today, many Americans use the terms “sweet potato” and “yam” interchangeably, although technically speaking, what they are referring to is usually a sweet potato. Despite the confusion, the term “yam” has become an integral part of American culinary culture, particularly during the holidays when sweet potatoes are a staple side dish.
