Kava, a registered dietician with a Ph.D. in nutrition, says these chemicals are naturally present in only trace quantities.
What's more, they have proven carcinogenic mainly to rodents if ingested in massive amounts. And even known human toxins or carcinogens may not be harmful at very low doses, she said.
