 Yogurt can consider as a healthy food first because of what it contains so its nutrients directly contribute to energy to a nutrient density of food and with respect to that population studies are demonstrating that the diet composition of yogurt consumers is characterized by an increased intake of calcium, magnesium, proteins which play a critical role in in homeostasis. Secondly yogurt is important because of its impact on concomitant energy intake including the possibility to influence appetite control. So on the basis of our experience yogurt consumption favorably influence appetite and ultimately results in reduced energy intake and recently we changed the ratio of dairy proteins within yogurt to increase the proportion of whey versus casein and it resulted in a substantial decrease in energy intake that exceeded the calorie content of the yogurt preload that we were providing. And finally yogurt might be what we call the signature of a healthy lifestyle. The idea being that the life habits of the yogurt consumer may predispose to metabolic health not only because of the content of the food but also because of the characteristics of other lifestyle factors.
