A new trial on Caiapo, an extract of white sweet potatoes taken in supplement form in Japan, confirms that it improves blood sugar and cholesterol levels in type 2 diabetic subjects. The Austrian researchers suggest it could be useful in the treatment of type 2 diabetes, affecting growing numbers of people around the world. The disease increased by one-third during the 1990s, due to the prevalence of obesity and an aging population and if nothing is done to slow the epidemic, the number will exceed 333 million by 2025, according to the International Diabetes Federation.
