Phytic Acid

http://www.nourishingdays.com/2010/09/what-is-phytic-acid/

Just making sourdough again (I want to do it regularly at work but need to find good recipes). Anyway, I was just thinking about the health benefits and wondering to myself what phytic acid is exactly – so I found this website (above). The author of this post also points us to:

http://www.food-info.net/uk/qa/qa-fp162.htm – according to this site, “Phytic acid (known as inositol hexaphosphate (IP6), or phytate) is the principal storage form of phosphorus in many plant tissues, especially in the grass family (wheat, rice, rye, barley etc) and beans. Phosphorus in this form is generally not bioavailable to humans because humans lack the digestive enzyme, phytase, required to separate phosphorus from the phytate molecule. …

Phytic acid binds to important minerals such as calcium, magnesium, iron and zinc and can therefore contribute to mineral deficiencies, as the minerals are not released from the phytate and are thus unavailable to the body. For people with a particularly low intake of essential minerals, especially young children and those in developing countries, this effect can be undesirable.

A common way in developing countries to increase the bioavailability of minerals from grains and beans is using fermentation. Many bacteria possess phytase activity and by fermenting grains or beans by lactic acid bacteria the phytate is destroyed and the bioavailability of the minerals is increased.

Phytic acid recently has been studied for its potential anti-carcinogenic properties. Recent studies have indicated that phytic acid may have some preventive effect in prostate, breast, pancreatic and colon cancer. The mechanism, however, is not yet understood.

About backyardbooks

This blog is a kind of electronic storage locker for ideas and quotes that inform my research... literary research into fiction for young adults (with a special focus on New Zealand fiction). Kiwis are producing amazing literature for younger readers, but it isn't getting the academic appreciation it deserves. I hope readers of this blog can make use of the material I gather and share by way of promoting our fiction. Cheers!
