The glass of milk, often recommended during the growth of children, is associated in our minds with strengthening bones.

But once an adult, is it necessary to continue to drink it?

Nutritionist Catherine Lacrosnière explains everything about milk on Wednesday in the program "Sans Rendez-vous" on Europe 1. 

From our earliest childhood we got used to drinking cow's milk every day to strengthen our bones thanks to the calcium it contains.

But once an adult, this habit is lost.

It even becomes, in some cases, difficult to digest milk.

Is this drink really meant for adults?

Better digested by children, milk is not reserved for them

Often better digested by the little ones, milk is not exclusively reserved for them.

It is easier to drink milk before "the age of 18, even 20 years", explains the nutritionist.

"Milk contains a sugar called lactose. It is digested in the intestine by an enzyme: lactase. We are born with this lactase, but gradually, especially if we have stopped drinking milk, the lactase disappears. Lactose is therefore no longer digested. This can cause digestive disorders, such as bloating, or even transit disorders ", she explains.

The ease with which we can digest milk would be a matter of habit for Catherine Lacrosnière.

"There are populations who continue to drink milk, in particular the Scandinavians. They will thus keep their lactases and will have no problem consuming this milk in adulthood," she says.

"A very good source of calcium"

And milk is undeniably a "very good source of calcium", according to the nutritionist.

She recommends it in particular for postmenopausal women to strengthen their bones.

If it is not digested, Catherine Lacrosnière therefore assures it: "we must find sources of calcium elsewhere."

And it is possible.

According to ANSES, there is calcium in cabbage, dried fruits and even certain mineral waters.
