Beet Root Juice Is A Significant Source Of Polyphenolic Compounds, Including Powerful Antioxidants

Beet root juice supplies a high level of dietary polyphenols, according to researchers from Oxford Brookes University
in the UK.

Writing in the Journal of Functional Foods, the researchers said that Beet root juice may provide "a significant source of dietary polyphenols," which contributes to the juice's high antioxidant content. They added that a liquid shot type drink "can provide a significant quantity of these bioactive components together with a convenient method for consumption."

"Given the potential for the multiple health benefits of polyphenol consumption, beverages containing high levels can be considered a positive addition to the diet,"

"Additionally, both sensory characteristics and convenience would appear to be important factors in obtaining an increased level of consumption amongst the general public," said the researchers from the Functional Food Centre at Oxford Brookes.

They added that specific interest in beet root has arisen because it is a rich source of a number of polyphenolic compounds consumption of natural produce that are rich in antioxidant compounds.

Beet root predominately contains betalains, a class of betalamic acid derivatives that are composed of betacyanins and betaxanthins, and other phenolic compounds that may offer excellent health benefits.

"Beet root juice contains a high level of biologically active antioxidants as well as many other beneficial, health-promoting nutrients such as potassium, magnesium, folic acid, iron, zinc, calcium, phosphorus, sodium, niacin, biotin, B6 and soluble fibre," said the authors.

Consumption of beet root in the form of a supplement capsule or liquid "shot" may provide a more convenient alternative to consuming the whole vegetable.

"Convenience is considered a considerable marketing tool in the food industry, and conscientious food manufacturers are looking for ways to make healthy food, particularly fruit and vegetables, more convenient to consume in order that public health may be improved," suggested the researchers.

The authors tested beet root juice liquid shot for their antioxidant contents, measuring the total antioxidant capacity and total polyphenol content of a 70 ml beet root juice shot after in vitro digestion.

The researchers reported that the shot delivered "a significant amount of antioxidants in a small, convenient volume," adding that total antioxidant count of the shot increased significantly following digestion.

"The results clearly demonstrate that antioxidants contained in this product become more accessible following digestion than those in other vegetable juice products," they said.

They concluded that a beet root liquid juice "shot" delivers a high amount of bio-accessible antioxidants and a cost effective and convenient method of increasing antioxidant status.
