Toxic Effects
Pak choi contains glucosinolates. These compounds have been reported to prevent cancer in small doses, but are toxic to humans in large doses. In 2009, an elderly woman who had been consuming 1 to 1.5 kg of raw Pak choi per day developed hypothyroidism, resulting in myxedema coma. There are other milder symptoms from over-consumption of Pak choi, such as nausea, dizziness and indigestion in people with weaker digestive systems. Sometimes this is caused by not thoroughly cooking.

Famous quotes containing the words toxic and/or effects:
“America today is capable of terrific intolerance about smoking, or toxic waste that threatens trout. But only a deeply confused society is more concerned about protecting lungs than minds, trout than black women.”
—Garry Wills (b. 1934)
“Each of us, even the lowliest and most insignificant among us, was uprooted from his innermost existence by the almost constant volcanic upheavals visited upon our European soil and, as one of countless human beings, I can’t claim any special place for myself except that, as an Austrian, a Jew, writer, humanist and pacifist, I have always been precisely in those places where the effects of the thrusts were most violent.”
—Stefan Zweig (18811942)
