Dietary silicon can help maintain bone strength and keep connective tissues in good shape, and is found in grains such as oats and barley—which also happen to be key ingredients to brewing beer. Previous studies suggest that, as a rich source of silicon, beer, in moderate amounts, might help fight the bone degradation of conditions such as osteoporosis. To see just how much silicon can be derived from a few brews—and determine which types of grains yield the highest amount of dietary silicon—researchers from the Department of Food Science and Technology at the University of California, Davis, tested 100 commercial beers, as well as the raw ingredients used to brew. They found that, in commercial beers, average silicon content ranges from 6.4mg per liter to 56.5 mg per liter. (While neither the U.S. or U.K. governments recommend a certain amount of silicon intake per day, both do advise against excessive silicon consumption—the U.K.’s Food Standards Agency recommends that silicon intake not exceed 700 mg per day.)

A mysterious decline in hip fractures

Hip fractures may be one of the most devastating injuries that humans face, but they’re also less frequent than they used to be. Today Canadian researchers announce that the hip-fracture rate fell 31.8% for Canadian women and 25% for Canadian men between 1985 and 2005. (A decline has also been noted in the U.S., but [...]

Low-birth-weight babies grow up to have low bone density as adults

Babies born too small are more likely to have low bone mineral density when they grow up, a new study reports today in the Public Library of Science journal, PLoS Medicine. Researchers in Helsinki, Finland, followed 144 Finns, now aged 18 – 27, who were all born preterm (before 37 weeks of gestation) and with very [...]
