Health Benefits of Sweet Potatoes

Different varieties of sweet potato offer slightly different nutritional advantages. Here are the big ones.

1. Immune health

Sweet potatoes with orange flesh are packed with beta carotene. The plant pigment that gives orange sweet potatoes their vibrant color represents antioxidant-like compounds that convert to vitamin A in the body. Studies suggest that vitamin A may support the healthy production of immune cells.

2. Brain function

Purple sweet potatoes may also benefit brain health, with a potential association to memory and cognitive performance. Sweet potato anthocyanin — a flavonoid responsible for the purple spud’s color — has been associated with cognitive function in mice.

3. Healthy vision

Those same pigments are believed to have a potential impact on overall vision health. Vitamin A in the form of the beta-carotene found in sweet potatoes may offer protective effects on eye health. Meanwhile, the anthocyanin in purple sweet potatoes may hold its own benefits for eye health.

4. Cardiovascular health

Potassium is abundant in sweet potatoes, and helps regulate proper fluid balance throughout the body. Combined with a reduction in sodium, it is believed that increasing potassium intake may impact circulation. Potassium has also been identified as a “nutrient of public health concern” as most Americans aren’t meeting their recommended intake.

5. Weight management

The carbohydrates found in sweet potatoes are primarily starch and fiber, as opposed to simple sugars. These carbs are digested more slowly and may promote greater feelings of fullness as well as lasting energy for the body.

What’s the glycemic index of sweet potatoes?

Glycemic index (GI) is the value (0–100) assigned to foods according to how slowly or quickly they cause increases in blood glucose levels or “blood sugar.” Foods high on the GI scale metabolize quickly, whereas those low on the scale release glucose more slowly.

However, the GI of sweet potatoes depends on many factors including preparation, origin, variety, year of crop, ripeness, and, more importantly, the other foods with which they’re combined. There’s such variability in the GI of sweet potatoes that it would be misleading to specify a single score.

Interestingly, one study found that “tubers processed by boiling had the lowest glycemic index while those roasted and baked had significantly higher glycemic indices.” Adding healthy fats, proteins, fiber (leaving the skin on), and managing portions are great ways to enjoy potatoes and manage healthy blood sugar levels.

Healthiest ways to make sweet potatoes

  • Mashed. Use a blender or mixer to puree cooked sweet potatoes, or just use a fork or potato masher to lightly mash them. Season with salt, pepper, and spices as desired. For a smoother, creamier consistency, add broth, water, or milk.
  • Baked or boiled. Bake in an oven at 400 degrees for 45 minutes to an hour, or boil for 15–20 minutes. Simply dice cooked sweet potatoes for addition to salads, soups, or entrées as a side.
  • Roasted. Wash and cut into wedges or dice into uniform shape, then place on a baking sheet. Add olive oil and salt, and bake at 375 degrees for 30 minutes, or until sweet potatoes are easily pierced with a fork.
  • Spiralized. Sauté in olive oil over medium heat until “al dente.”
