Fish Bones Are A Rich, Readily Available Source Of Absorbable Calcium - Study

August 1, 2010: 09:25 AM EST
Fish bones, which are readily available in huge quantities as a by-product of the fish farm industry, are rich in calcium that is easily absorbed in the bodies of young, healthy men, a Norwegian/Danish study has found. Researchers processed bones from Atlantic salmon and cod into powders. Ten young men were then fed meals containing either a commercial calcium supplement or the processed salmon and cod bones. Absorption of the fish bone-derived calcium was then compared with the calcium supplement using a whole-body counter. It was found that calcium from the two types of fish bone was absorbed equally well, and the absorption was not significantly different from the calcium supplement. The researchers concluded that processed fish bones can be conveniently used as a high quality food ingredient or supplement.
