Is Phytic Acid Good or Bad for your health?

The "Good" - Phytic acid confers some health beneficial effects

Particularly when consumed in moderation.

The bible contains several positive references to eating bread (especially unleavened bread).

Dietary phytic acid (often referred to in studies as inositil hexaphosphate or IP6) has several health-protective functions:

Strong antioxidant

•  Binds transition metal ions, thwarting their role as oxidants.    Phytic acid-rich diets may protect cells lining the intestinal mucosal membrane (epithelial cells)  against iron-induced oxidative damage;

Interruption of cellular signal transduction,•  Cell cycle inhibition

Enhancement of natural killer (NK) cells activity.

Health benefits of phytic acid:

Cancer

• Decreases risk of colonic cancers and protects against inflammatory bowel diseases -  Although both Finland and Denmark populations consume equal amounts of fiber, the lower-risk Finns consume food items with 20-40% more phytic acid than the higher-risk Danes.

• Phytic acid shown to inhibit growth of cancer cells - e.g. leukemia, colon, breast, cervical,
  prostate, liver, pancreatic, skin, and muscle.  after seemingly being taken up by them after absorption from the GI tract.

• Blocks angiogenesis (formation of new blood vessels to feed cancer cells) and disrupts pre-formed vessels.

• Appears to enhance anti-cancer effect of chemotherapy

Type 2 diabetes

Coronary heart disease / Atherosclerosis - by lowering elevated serum cholesterol; reducing pathological platelet activity

Kidney stone formation - by preventing calcification

HIV-1

Heavy metal toxicity - by binding to transition metalsOsteoporosis
