Sweet Potato vs. Yams

Sweet potatoes are often referred to as yams, and for many, the terms are considered pretty much interchangeable. However, not only are they two entirely different plants, but there are some other major differences between yams vs sweet potatoes.

First of all, the sweet potato belongs to the morning glory family of plants while yams — not to be confused with Mexican yams or wild yam — are actually related to lilies and grasses. Additionally, sweet potatoes are thought to have originated in Central and South America while yams are native to Africa and Asia.

There are also some significant differences in the appearance of the yam vs. sweet potato as well. Sweet potatoes have tapered ends with smoother skin and can range in color from white to vibrant orange and purple. Yams, on the other hand, have rough skin and are typically white-fleshed and cylindrical. Yams are also more starchy and dry without the hint of sweetness found in sweet potatoes.

Gram for gram, yam nutrition is higher in calories, carbohydrates and fiber but slightly lower in protein than sweet potatoes. Yams also contain a good amount of vitamin C, vitamin B6, potassium and manganese but are not as nutrient-dense as sweet potatoes.

Sweet Potato Nutrition vs. White Potato Nutrition

Although both have become common kitchen staples, there are some distinct differences between white potatoes and sweet potatoes. They both belong to different plant families, are notably different in terms of appearance and each has a unique taste that sets it apart. While white potatoes are often incorporated into savory dishes, sweet potatoes have a flavor that works for both desserts and main courses alike.

But are sweet potatoes healthier than regular potatoes?

Looking at the sweet potato vs. potato in terms of nutrition, each brings a different set of nutrients to the table. White potato nutrition, for example, is especially high in certain micronutrients like vitamin C, folate, vitamin B6, potassium and manganese, while sweet potatoes are significantly higher in vitamin A.

Per 100 grams, there are 20.7 grams of carbs in sweet potato compared with 21.5 grams of carbs in regular potatoes. Meanwhile, the amount of sweet potato calories is slightly lower as well, with 94 calories in a potato compared to just 90 calories in sweet potato. Sweet potatoes are also slightly higher in fiber and have a lower glycemic index, meaning they don’t cause the same sharp increase in blood sugar as regular potatoes.

However, both can be healthy additions to the diet when used in moderation and with proper portion control. Preparation method is also key; potatoes are often deep-fried and doused in oil and salt, which depletes their nutritional value. Try them baked instead of fried and enjoy a few servings of both sweet potatoes and regular potatoes as part of a nutritious diet.
