Story-at-a-glance version:

One of the best ways to achieve healthy bones is a diet rich in fresh, raw whole foods like vegetables, which maximizes natural minerals. Fermented vegetables using special starter culture designed to optimize vitamin K2 is one of your best strategies for maintaining healthy bones and preventing bone loss.

New research shows eating the seeds of the fennel plant had a beneficial effect on loss of bone mineral density, as well as bone mineral content. Researchers indicated that fennel seeds show potential in preventing bone loss in postmenopausal osteoporosis.
Vitamin K2 is an important fat-soluble vitamin that plays a critical role in building strong bones, as its primary function is to move calcium into the proper areas, such as your teeth and bones. It also helps remove calcium from areas where it shouldn�t be, such as in your arteries and soft tissues.

The optimal amounts of vitamin K2 are still under investigation, but it seems likely that 180 to 200 micrograms of vitamin K2 might be enough to activate your body�s K2-dependent proteins to shuttle calcium to the proper areas.

And speaking of Vitamin K...I lived on yet another island, this one out in the Aleutians...Island past time for some was going to the dump to shoot rats. The rats were rather immune to rat bait due to the very high Vitamin K levels in crab shells. Ground crab offal & shell in very huge abundance out there.

I wonder how many seeds equal how many Micrograms of K2?

Thank you for sharing this article.
