简要总结
In the early 1980s and following the first publications by Jenkins et al., The notion of glycemic index (GI) appeared with the aim of classifying the different sources of carbohydrates in our diet according to their effect on the post-prandial glycemic response. Since these years, many studies have been designed to determine the usefulness of the glycemic index and indicate that a low glycemic index for a food, a dish, a meal or a diet is associated with a decreased risk of metabolic pathologies (diabetes, hypertriglyceridemia), degenerative (cardiovascular diseases) or overload (obesity). This justifies the interest in favoring foods with a low glycemic index in healthy subjects.
A review confirmed the mechanistic link between postprandial blood sugar and the variability of blood sugar, making it possible, on the one hand, to maintain good glucose homeostasis and, on the other hand, to prevent pathologies such as obesity, diabetes and cardio-vascular diseases. The EFSA also considers that reducing the increase in blood sugar in the post-meal phase can be considered a physiological benefit, especially in subjects with glucose intolerance.
Post-meal blood sugar depends on many factors including the glycemic index of foods eaten during the meal. Knowing the glycemic index of foods is therefore very useful.
Mademoiselle Dessert offers pastries with a low glycemic index. The objective of this study is thus to determine the glycemic index of 6 pastries in order to inform consumers on these pastries glycemic index.
详细描述
The study will be carried out on healthy volunteers, aged from 18 to 65 with a body mass index (BMI) between 18 and 30 kg/m² (limits included).
The main objective of the study is to determine the glycemic index of 6 pastries in healthy volunteers with 7 kinetic points (0, 15, 30, 45, 60, 90 and 120 min).
