I eat sweet potatoes every morning for breakfast. It's one of the most enjoyable changes I made in my diet post-cancer, along with the lifestyle change to consciously enjoy life.
Sweet potatoes are among the healthiest common whole-food sources of potassium, which every cell in our body requires to function. In fact, they can be considered a superfood and are ranked as one of the healthiest foods on the entire planet. Eighty percent of the protein in sweet potatoes is a type of protease inhibitor that may have cancer-fighting properties.
When picking out varieties at the supermarket, remember that a sweet potato’s nutritional content is tied directly to the intensity of its color. The more yellow or orange its flesh, the healthier it may be, and purple sweet potatoes are even healthier.
The traditional diet in Okinawa, Japan, one of the longevity Blue Zones, was based on vegetables, beans, and other plants. Less than 1 percent of their diet was fish and less than 1 percent was other meat, and the same with dairy and eggs, so it was more than 96 percent plant-based. And, as they ate very few processed foods, it was more than 90 percent whole food plant-based. And, it wasn’t just whole food plant-based in general. Most of their diet was made up of vegetables with one in particular—the sweet potato. How delicious that the Okinawan diet was centered around purple and orange sweet potatoes!
