Sweet Potatoes

Sweet potatoes are rich in starch, dietary fiber, potassium, and vitamin C. Dietary fiber suppresses the rise of cholesterol and blood sugar levels and improves the intestinal environment. Potassium helps excrete excess salt and contributes to regulating blood pressure. In addition, the vitamin C contained in sweet potatoes is not easily destroyed even when heated. Sweet potatoes also contain folic acid, which helps with cell production and repair and is an important nutrient, especially for pregnant women.
The resin component called yarapin contained in sweet potatoes has the effect of softening stool. In addition, the skin of sweet potatoes contains a pigment called anthocyanin, which protects capillaries, has antioxidant properties, and helps protect eyesight. Sweet potatoes with purple flesh also contain a lot of anthocyanin. Additionally, sweet potatoes with orange flesh are rich in beta-carotene.

Select sweet potatoes that have deep and even coloring and are not damaged or bumpy on the surface. As they are susceptible to cold temperatures, sweet potatoes are not suitable for refrigerator storage. The optimum temperature for storage is about 15°C (60°F).

Sweet potatoes are well-suited for deep-frying (Tempura), in boiled dishes as well as for a sweet snack, to make the most of their natural sweet flavor.
