What is it about?
Middle age and elderly participants who drank one glass of milk every day were at lower risk of developing hypertension and this was probably not due to calcium content of milk.

Why is it important?
Other studies had shown that dairy intake is associated with lower risk of hypertension, but those studies were limited to high range of dairy intake. We showed that the inverse association exists even in intake levels as low as just one glass of milk per day. Moreover, thank to various sources of dietary calcium in this population, we managed to provide evidence showing that this inverse association may not be attributable to calcium which is usually proposed as the potential mechanism of good impact of dairy on hypertension.
Perspectives
The benefits of dairy intake, specially drinking milk, can strats from low doses. On the other hand, we showed that this may not be achieved by calcium supplements. Thus, those who have lactose intolerance may still enjoy the benefits of milk at levels that do not induce symptoms seriously. However, this need to be further tested in future studies.
