Effects of Pinitol on Hidrocarbonated Metabolism Parameters in Diabetic, Impaired and Normal Fasting Glucose Subjects

Fruit Up® (diluted with mineral water to a final volume of 250 ml) will be evaluated, and will be equivalent to an intake of 2 g of pinitol. The placebo beverage will contain equal amounts of non-polyol carbohydrates with similar macronutrient composition and energy intake as that those obtained through the pinitol beverage, but excluding pinitol.
