The aim of the study is to evaluate the effects of an acute intake of two fermented fruits flours as part of a standardized breakfast, in comparison with the acute intake of a standardized breakfast without fermented fruits flour but with the same amount of available carbohydrates, on postprandial glycaemic response and overall metabolism in subjects at cardiometabolic risk.
The metabolic parameters will be assessed in fasting and in postprandial period after the consumption of the standardized breakfast.
