You’re going to love the creamy texture naturally sweet taste of roasted purple sweet potatoes.
Purple sweet potatoes are a stunning side dish with their vibrant purple color. Not only do they look like food for royalty, but they are also considered a longevity food. You may have heard about Okinawans who have a life expectancy of 83.7 years. (Compare that to the expectancy of an American and you’ll see a five-year difference!)
According to a decade-long study of the Okinawan people, it appears that a key factor in the Okinawans’ vigorous health and longevity can be attributed to the consumption of purple sweet potatoes. Okinawans reportedly eat an average of half a kilo (1 pound) of purple sweet potatoes per day. ~ Purple Sweet Potatoes May Help You Live Longer
Purple sweet potatoes are exceptionally high in antioxidants, particularly anthocyanin, which is the same antioxidant that you’ll find in blueberries, purple cabbage, and others. However, the level of this special antioxidant, anthocyanin in purple sweet potatoes is around 150 times higher than in blueberries.
One study found that anthocyanin was helpful in protecting against colorectal cancer. This antioxidant also contributes to eye health.
How to prepare purple sweet potatoes
To reap even more of the health benefits of these purple sweet potatoes, we’re going to roast them with the skin on. So before you cook them, give them a nice scrub in a tub of water using a stiff bristle brush. Sweet potatoes are tubers and grow underground, therefore you will often see a bit of dirt on them.
My grandpa used to say “a little dirt won’t hurt” but grit will ruin your eating experience, so scrub them well! Potato skin has concentrated nutrients, so leave it on when you can.
Purple sweet potatoes have a lot of potassium and most of that is found in the skin. Since potassium is good for your heart, may as well use this source rather than toss it in the compost. In addition, both the purple and regular sweet potatoes contain a significant amount of vitamin C which is often lost in cooking. Higher concentrations of vitamin C can be maintained when you leave the skin on.
Roasting sweet potatoes year-round for your dinner table (or breakfast and lunch!) will help keep your immune system strong. So don’t eat them just on Thanksgiving Day. You want to enjoy them as often as you can!
Besides, I love the taste of crispy sweet potato skin! When my kids wouldn’t eat their sweet potato skin I would always be the one who ended up with it on my plate. For years my older children would offer me their sweet potato skins!
