Some Plant-Based Food Supplements Contain High Levels of Cancer Causing Agents
ScienceDaily (Dec. 12, 2011) — While many consumers equal ‘natural’ with ‘safe’, botanicals and botanical preparations such as plant-based food supplements may contain compounds, like the so called alkenylbenzenes, that are of concern for human health. At high doses these chemical compounds can cause liver cancer in experimental animals. A new study, published in the last issue of the journal Food and Nutrition Sciences, reveals that in many plant-based food supplements levels of these compounds are so low that they are of no concern. Although there are also plant-based food supplements on the market that contain alkenylbenzenes at levels comparable to those causing tumours in laboratory animals. This indicates a need for better regulation and quality control of plant-based food supplements containing alkenylbenzenes.
