And an earlier examine he and colleagues put collectively in 2014 discovered that there was a 9% higher danger of later hip fracture for every further cup of milk per day consumed by teenagers, however not women. In a country-to-country comparability, Willett and Ludwig discovered larger charges of hip fractures in international locations that consumed larger quantities of milk and calcium.

And linking elevated human consumption of IGF-1 with most cancers and insulin resistance.
Weight reduction: Clearly, low-fat or fat-free milk is a more healthy choice than sugary or eating regimen sodas, teas and different processed drinks in the marketplace. Willett famous that research of dairy merchandise confirmed that yoghurt alone was related to much less weight acquire.
