Phytate

Phytate or phytic acid is a unique natural compound found in plant seeds. It has the potential to bind to minerals such as calcium, iron, and zinc, reducing their bioavailability in the human diet. Despite this, phytate also has several health benefits, including antioxidant effects and potential anti-cancer properties.

Chemical Structure

Phytate is the principal storage form of phosphorus in many plant tissues, especially bran and seeds. It is a hexaphosphate of inositol (specifically, myo-inositol), and its chemical formula is C6H18O24P6.

Sources of Phytate

Phytate is found in a wide variety of foods, but is particularly high in legumes, whole grains, nuts, and seeds. It is also present in some fruits and vegetables, but to a lesser extent.

Health Implications

Mineral Binding

Phytate's ability to bind to minerals and reduce their bioavailability has led to concerns about its impact on human health. This is particularly relevant in populations that rely heavily on legumes and whole grains as dietary staples and may not have access to a diverse diet.

Health Benefits

Despite its potential drawbacks, phytate also has several health benefits. It has been shown to have antioxidant effects, and may also have anti-cancer properties. Some research suggests that it may help to reduce the risk of kidney stones, heart disease, and even some types of cancer.

Reducing Phytate Levels in Food

Several food preparation techniques can help to reduce the levels of phytate in food. These include soaking, sprouting, and fermenting foods, as well as combining them with foods rich in vitamin C.
