MORALES GUERRERO, Josefina Consuelo et al. Determination of the glycemic index and glycemic load of fermented dairy products in sedentary healthy adults and athletes. Nutr. Hosp. [online]. 2016, vol.33, n.5, pp.1095-1101. ISSN 1699-5198.  https://dx.doi.org/10.20960/nh.572.

Introduction: Glycemic Index (GI) and glycemic load (GL) of natural dairy products fermented with lactobacilli may be useful for diabetic patients and the general population. Objective: To measure the GI and GL in natural dairy products fermented with lactobacilli in sedentary individuals and athletes, and seeing if there is any difference between them. Methods: The study was conducted in Mexico City (DF) according to the ISO26642:210, with a group of 10 sedentary individuals and 10 athletes. The GI was determined in the following diary drinkable products, all adjusted to contain 25 g of carbohydrates: Soful, Yakult, Gastroprotect, BeneGastro, Bonacult, Lala Bio 4 and Skimmed milk with sucrose (SMS). Results: The GI of most dairy fermented products were low for sedentary and athletes, but in athletes Yakult and Bonacult showed the highest GI and Yakult's GI can be considered as medium for these group; these two dairy products had the lowest protein/carbohydrates ratio. SMS, which contain unfermented carbohydrates, had the highest GI in both groups. The GL of dairy fermented products was 4 to 7.6 and only Gastroprotect had statistically the lowest GL, it may be due to its low GI, even its serving size was not the least among dairy fermented products. Conclusion: The GI and GL levels were relatively low for all the dairy products considered on each of the groups studied, therefore the moderate consumption of these can be recommended.
