Sweet Potatoes Vs. White Potatoes: A Nutritional Showdown

Sweet potatoes are often regarded as a healthier alternative to the white potato, which has been recently criticized as “Public Enemy No. 1” in America’s ongoing struggle with obesity. Some nutritionists even compare sweet potatoes to white potatoes in the same way brown rice is compared to white rice. This leads us to question: are sweet potatoes truly the superior choice, or are they just marketed that way?

In a direct comparison, these two tubers exhibit surprising similarities. For instance, in a 100-gram serving, the white potato contains 92 calories, 21 grams of carbohydrates, 2.3 grams of dietary fiber, 2.3 grams of protein, and 17% of the daily recommended value of vitamin C. Conversely, a similar serving of sweet potato has 90 calories, 21 grams of carbohydrates, 3 grams of fiber, 2 grams of protein, 35% of the daily recommended value of vitamin C, and an impressive 380% of the daily recommended value of vitamin A. Despite these comparable stats, the sweet potato enjoys a better reputation.

It may initially seem surprising that sweet potatoes have garnered such acclaim when the data to confirm their superiority is lacking. According to a study by the New England Journal of Medicine, there isn't enough research to determine whether sweet potatoes significantly impact Americans' waistlines compared to their white counterparts. This discrepancy is likely due to the fact that Americans consume far fewer sweet potatoes, averaging only 5.2 pounds per year, which is less than 5% of the average 117 pounds of white potatoes consumed annually.
