This project targets an important global challenge; the incidence of osteoporosis and its associated fracture risk is anticipated to become a worldwide burden due to the ongoing demographic changes towards ageing populations. It is estimated that approx. 6 % of men and 21 % of women aged 50–84 years have osteoporosis, and that osteoporotic fractures account for 2 million disability adjusted life years (DALYs) alone in Europe. The reason that why post-menopause women are easier to suffer osteoporosis may be related with gut-bone axis. Thus, in this project we will investigate if we can enhance calcium absorption through concomitant use of bioactive dairy calcium and promotion of a favorable gut environment through inclusion of prebiotic and/or lactose in the food matrix.


The project aims to explore how the combination of a dairy calcium source with prebiotic inulin can create a gut-bone food concept to promote the absorption of calcium and hereby improve bone mineralization.


The ECAMO project, basing on rat experiments, will document that calcium absorption and thereby bone mineralization can be modulated by combining dairy calcium with inulin and/or lactose in a food matrix. The project will thereby facilitate the development of a gut-bone food concept where calcium absorption is enhanced through a strategic food design with a combination of a bioactive dairy calcium ingredient and fermentable dietary fiber inclusion.
