Bananas are famous for their potassium—a mineral that helps control our blood pressure. But while a banana has nine percent of your daily needs, a baked regular potato has twice as much—20 percent—and a sweet one has 12 percent. But watch how you cook them: Cubing potatoes before boiling can reduce potassium by 75 percent. The best way to maintain it? Bake with the skin on.
Inhibit cancer cell growth
A sweet potato’s orange colour comes from beta-carotene: the darker the hue, the higher the content. Like other carotenoids, beta-carotene turns on a gene that encourages our cells to communicate. While normal cells “listen” to their neighbours, cancer cells don’t communicate, and act on their own
Feed your bones
Maintaining bone health requires a complex mix of nutrients, yet a Spanish study found that manganese on its own helped prevent bone loss in rats. Sweet and regular potatoes are good sources of this mineral: A baked medium sweet with skin has 32 percent of your daily needs; a baked regular with skin has 22 percent.
Control blood sugar
Surprise! Despite their name,
sweet potatoes raise your blood sugar level 30 percent less than regular potatoes. This is thanks to their high soluble fibre content
. So if you’re worried about blood sugar fluctuation, go against intuition and reach for
a sweet variety.
