Sweet Potatoes vs. White Potatoes: Which is Better?

Which Potatoes Are Better?

Potatoes seem to have gotten a bad rap…and for good reason. According to the USDA, over 50% of potatoes make it into french fries, chips and other processed potato products, which aren’t doing anything good for our health.

But let’s take a look at the fresh, whole food version of potatoes and see how they stack up to their orange counterparts, the sweet potato, in our potato showdown.

Macronutrient Breakdown

• Carbs 90-93%, 1% fat, 6-9% protein
• Ounce for ounce, they have about the same calories, or about 90 calories per 3oz baked potato (in skin)

Winner = Draw

Micronutrient Breakdown

• Both potatoes have potassium, which is good for regulating blood pressure and replacing potassium lost in sweat. White potatoes have slightly more potassium, with 1 medium potato containing about 21% of the daily value for potassium compared to 15% in 1 medium sweet potato.
• The big difference, between the two, is in the vitamin A content. Sweet potatoes have a ton of vitamin A, around 19,000 IU. Vitamin A is beneficial for eye health and is an antioxidant good for combating free radicals produced during exercise.
• If you eat the skin, the white potato has slightly more iron.

Potassium Winner = White Potato (barely)

Vitamin A Winner = Sweet Potato (by a landslide!)

Why We Sweet Potatoes

• Sweet potatoes have more flavor and therefore, require less flavorings, such as salt, to be added. Some people may need to limit their salt intake. They adapt well to savory or sweet applications too.
• Sweet Potatoes are more versatile and can be baked, roasted or made into noodles. Many sweet potato recipes also utilize sweet potatoes as a meatless option for example in tacos with black beans or shredded as a vegetarian sloppy joe.
