Sweet Potato Extract & Blood Sugar: The Trial
Sweet Potato · มันเทศ · Ipomoea batatas
Sweet Potato — มันเทศ (man-thet) — Ipomoea batatas.
One trial found that Caiapo, an extract from a white-skinned sweet-potato variety, improved blood-sugar control in people with type 2 diabetes. The study tested the extract; the edible part is the tuber. Sweet potato is rich in vitamin A, vitamin C, potassium, manganese, and fiber. Fiber adds bulk to meals, can help with fullness, and can slow carbohydrate absorption as part of a mixed diet. Khanom Khai Nok Kratha are crispy, chewy deep-fried sweet potato balls traditionally served hot as a popular street snack alongside hot jasmine tea. Man Tom Khing features tender sweet potatoes simmered in a warm, sweet ginger-infused broth, commonly served after hot meals as a comforting palate cleanser. The young leaves are also edible and commonly eaten as a cooked green. Eat it with a little fat — a drizzle of oil or coconut helps your body absorb the beta-carotene that makes it orange, since that nutrient is fat-soluble. Grow from 'slips': sprout shoots from a tuber in water, snap them off once rooted, and plant them. Follow Longevity Biome for a new Thai plant every day.
