NUcheckt: Why milk can help your bones to make it stronger

NU.nl check daily posts on reliability. This time the statement: ‘Milk makes for weaker bones.’

Opinion: Unlikely

According to the RIVM, Dutch people are becoming less and less milk to drink. And according to posts on blogs as Ninefornews and Strong, that is good news for your bones. In the messages is claimed that the bones are from milk not stronger, but weaker. Is milk really bad for your skeleton?

Where does it come from?

Ninefornews refers to a Swedish study from 2014 which found that Swedish women who have little to drink milk less often fractures up than women who have lots of milk to drink.

The researchers emphasize in the conclusion of their research that you on the basis of what they have found can’t say that milk consumption is also the cause of bone fractures. The researchers looked also to men, but in men there was no relationship between melkinname and fractures found.

Is it true?

Joop van den Bergh, professor of bone quality and Metabolic bone diseases at the Maastricht UNIVERSITY medical centre and VieCuri MC Venlo, explains that if we are talking about milk and bones, we are talking about the calcium in milk. “Milk is rich in calcium, which is an important building block for the bones. Calcium, for example, also in other dairy products and some green vegetables, such as broccoli.”

Also Natasha Appelman-Dijkstra, head of the Center for bone quality at the Leiden University Medical Center, explains that calcium is important for healthy bones. “Together with phosphate, which is, for example, in wholemeal products and dairy products, is calcium the cement of the bones. Vitamin D is also necessary for the absorption of calcium.”

“Milk is for many Dutch people are an important source of calcium, but you can also with the plant-based diet adequate calcium in their diet. For the bones it does not matter whether the calcium from animal or vegetable food. For the health in general it can of course be part or your calcium from full-fat milk or broccoli.”

Can too much calcium for weak bones?

Van den Bergh says that for almost all processes in the body calcium necessary for the contraction of the heart. “If the amount of calcium in the blood becomes too low, the body the calciumvoorraden in the skeleton. As the body for a long period of time must do, this can be bad for the bones.”

“You can have a deficiency of calcium in your blood because it is not enough in your diet, but a deficiency of vitamin D can also ensure that you have insufficient calcium from the intestines absorb.”

Van den Bergh explains that if someone more calcium intake than the body needs, this is also not included and thus disappears from your body. “More calcium wider than needed so not good for the bones. In research, we find also positive effects of milk if there was a deficiency of calcium.”

This also confirms Appelman-Dijkstra. “There is indeed a limit to the amount of calcium that the intestines absorb. Not included calcium your body. I can’t think of how too much calcium for worse bones could provide.”

Melkinname difficult to measure

How about studies which would prove that milk is bad for the bones? Van den Bergh explains that there is, indeed, studies in which a link has been found between milk and an increased risk of fractures, but on the basis of these investigations is not to say whether or not there is a cause-and-effect relationship.

“In this kind of investigations is usually on people asked how much milk they drink, and is on the same or a later time, see how many broken bones these people have suffered. It is only nearly impossible to melkinname for a longer period as well note that you can say that the melkinname whether or not a cause of bone fractures. Often, for example, only during one week, track how much milk a person drinks.”

In addition, according to Robben in this type of research, it is not possible to take into account all factors that can influence. “For example, it is possible that someone after a fracture more milk drinking, because he has heard that milk is important for the bones. In that case, the fracture is rather a cause for the higher milk intake than the result.”

How much calcium should you consume?

Van den Bergh explains that, on the basis of what we know about the bones, milk when there is a shortage of calcium is absolutely positive. But if the calciumniveau in balance, your bones are probably not much whether you add extra milk. “The recommended amount of calcium is 800 to 900 milligrams. This you get for example if you have a varied diet and, in addition, two to three zuivelconsumpties.”

Conclusion

A prolonged deficiency of calcium may cause weaker bones. It is therefore important to have sufficient calciumrijke food to eat, such as dairy products. It is only likely not so that more calcium is always better. If there is enough calcium in your body takes the extra calcium is not and has therefore no effect on bone strength.

In a Swedish study was, however, an association was found between a high intake of milk and broken bones, but there are several reasons why you on the basis of this research can not conclude that a lot of milk to drink for weaker bones.

We rate the statement ‘Milk makes for weaker bones” as unlikely.
