There comes a big, big counterorder to a diet richer in dairy products and cheeses.
No, it does not cause a greater risk of fractures, but on the contrary it reduces the incidence by 30%.

In fact, many people are convinced that a diet with dairy products and cheeses can cause a greater risk of fractures, due to a “demineralization” of the bones.

Others talk about acidic foods that would cause this problem, such as dairy products.

DIET RICH IN DAIRY PRODUCTS: IS IT GOOD FOR BONES OR NOT?

The first belief comes from a distant 1997 study on women , which lasted twelve years, but which was based on questionnaires completed by the participants at four and two years, with three main interviews. In essence, the more than seventy thousand women interviewed three times in twelve years were asked to tell how much milk and dairy they consumed, and if they had had any fractures. The study, although questionable in its method, made a lot of echo. So much so that to this day it is often cited as “incontrovertible proof”.

Think about it for a moment. With no other data, seventy thousand women replied by post to three questionnaires on what they had eaten in twelve years. And from there, a correlation with only one other data available. The incidence of their fractures. You understand that the results are far from being used as scientific proof.

The speech instead of acidity comes alas from the alkaline diet .
A diet that is not scientifically supported, the creator of which has been in big trouble with the justice system.

In short, on balance, there is much more evidence on the association between consumption of milk and dairy products and better cardiovascular and bone health than the other way around.

See for example the study published in Osteoporosis International in 2019 , a review of all previous studies where their limitations were also analyzed.
A review of Caucasian and Chinese women who had stronger bones when consuming milk and dairy products, fortified or not. An Italian meta-analysis from 2019. 

DAIRY PRODUCTS IN THE DIET: THE FIRST STUDY THAT SHOWS THAT THEY ARE GOOD FOR BONES.

And now, a new Australian study that analyzed the incidence of fractures in a group of women living in nursing homes. In this case, the University of Melbourne analyzed calcium consumption by dividing women into two subgroups for two years.

One of these received the recommended dose of calcium for those over 60 (1100 mg) through milk, dairy products and cheeses, in the other the women ate a normal diet where calcium, according to the researchers, reached half the daily dose.

Regardless of vitamin D values, women who fed more milk and dairy had thirty percent fewer fractures on average, and eleven percent fewer falls. All the participants also underwent analysis of the musculoskeletal system to highlight traces of demineralization or loss of density, and periodic blood tests.
Those who ate more milk, dairy and cheese had higher bone density.

This is the first randomized study between diet and bone ever done so far, where it is finally possible to notice a causal link.
