Okinawan Sweet Potato (Japanese sweet potato/yam)
Although these are native to North America, and not Japan, they serve as the main carbohydrate source in the traditional diet of the Okinawan people, the longest-living people in the world.
So what’s good about this purple sweet potato? It has all the nutrients the average American person lacks! One potato (~180g) has 700% of the Daily Recommended Value of Vitamin A. Unlike others foods like nuts & oils which are rich in Vitamin E, this sweet potato has the antioxidant without the extra fats.
- High in fiber
- Rich in Vitamins A, C, B6
- Good source of Potassium, Iron, & Calcium
- Low to medium GI (Glycemic Index)
It’s also really tasty & easy to prepare! They can be found at any Asian market or even regular markets marked as “Japanese sweet potato/yam.” But from my understanding, all sweet potatoes are generally as nutritious.
- Poke the sweet potato with a fork several times all around
- Wrap in a wet paper towel
- Microwave for 5 minutes, turning once at 2.5 minutes.
