How Does A Ringworm Look When It's Healing

Beer can help keep bones strong

Researchers at the Department of Food Science and Technology, University of California found that beer is a rich source of silicon and can help prevent osteoporosis, because this chemical is a key for increase bone mineral density.

These are the conclusions drawn after researchers tested 100 brands of beer to measure their silicon content, and categorized by the type and source of beer.

Previous research suggested that beer contained silicon, but little was known about whether this component varied depending on the types and malting.

"We examined a wide variety of types of beer for their silicon content and study the impact of raw substances and processes on the amount of chemical present in beer and fermented malt," said researcher Charles Bamforth said in a statement.

The study, published in the Journal of the Science of Food and Agriculture found that the silicon content of beer varied between 6.4 and 56.5 milligrams (mg) per liter . Daily consumption of silicon per person is between 20 and 50 mg.

Data:

  • Lagers, contained the highest content of silicon, while those who do not carry alcohol, "light" and wheat were the parts that lacked it.
  • Beer contains high levels of malted barley and hops are the richest in silica, Bamforth said.
