Brief summary
The study examines the effect of black currant on glucose and insulin concentrations after a meal. In addition, the cytokine and free fatty acids levels are of interest.
Detailed description
The study examines the effect of black currant on glucose and insulin concentrations after a meal. Healthy (n= 30) volunteers are recruited to participate in four consecutive visits in the research laboratory, when four meals are served in randomised order. Meals are: black currant puree, black currant and quinoa based snack, quinoa base and liquid containing glucose, fructose and sucrose. The meals contain the same amount of carbohydrates. In addition to glucose and insulin concentration, cytokine and free fatty acid concentrations are measured after each meal.
