 So, to address the issue of the key benefits of dairy products and bone health, we should remind that a well-balanced diet is mandatory, including both calcium protein as well as phosphorus and different trace elements and vitamins. In other words, there is no magic bullet, so it's unlikely that just dairy product could replace all the needs. However, since calcium and proteins are needed for ensuring bone health, this means that the source of calcium and protein, like dairy products, are very useful since the dairy products are covering nowadays approximately two-thirds of the needs per day and between 14-50 percent of the needs of protein. And this is both easy because everything is within the same nutrient and relatively cheaper as compared with other sources of calcium and proteins. During the adolescence, the bone capital is doubling, so this means that it's an accelerated bone growth during which we need to mineralize the bone which has been newly formed. And the mineralization is obtained through calcium and phosphate. And then we need also some well-balanced diet including proteins, since the proteins are also the regulator of the hormone IGF-1 which promotes the growth of both in the longitudinal and radial way of the bone. First of all, in the middle age, between the age of 50 and let's say 16, the women where the menopause is associated with a marked increase in bone turnover and accelerated bone loss, well-balanced diet is certainly important but could not replace the lack of hormones. On the other hand, in the more advanced age, when there is a high prevalence of malnutrition, in this case, calcium proteins are the first for some mandatory. And instead of using supplements, when these components are included in the diet, it's much more physiological, and in terms of absorption, it's probably better. The different issue which should still be solved in terms of via goat and ballhands is the amount of via goat we should have to ensure enough control of bone turnover particularly in the elderly. Second of all, what we should also look at is the relationship with the muscle, how much yoghurt we need to have enough strength in the muscle, and finally, there is a major interest to see how the yoghurt could modify or not the flow of large intestine to improve the absorption of calcium.
