化學物人人有份 Income Determines the Chemicals We Eat

貧、富體內化學物大不同

英國最新一份研究指出,無論你是富或窮,人類的體內都積聚了不少化學物,只是種類不同,例如富人體內的化學物來自海鮮、防曬乳霜;窮人的來自煙草等。

富人吃海鮮的機會較多,體內的水銀、砷、鉈、全氟辛酸(PFOA)等的含量亦較多。而常見於防曬產品、可致敏的二笨甲酮,以及其他跟食物包裝和洗髮水有關的化學物,也較常見於富人身上。

窮人則因居所接近工廠區,又多愛吸煙,因此體內的鉈、鎘、鉛等含量較多。跟即食食品包裝有關的化學物質,也較多在窮人體內發現。蒂雷爾直言,對於有錢人體內也有這麼多化學物頗感意外,又指現代人較多機會接觸到化學物,因此對身體構成不少負擔。

The Toxic Class Divide: Income Determines the Chemicals We Eat
We all consume toxins in our food—but some are more expensive than others.

Toxins don’t care about class. Give them a body to take up residence in and they’ll settle right into those organs, regardless of their host’s net worth.

However, a new study of chemical levels in Americans has shown that while toxicity is equal opportunity, the sources of those toxins are not. So while poorer people are more prone to high levels of BPA, which can leach into cheap canned foods, the upper classes harbor more mercury, arsenic, caesium and thallium—all associated with pricy fish and shellfish.

And the class divide in toxicity isn’t limited to foodborne chemicals. The study, conducted by the University of Exeter, found other income-specific causes of gradual poisoning after analyzing data from the U.S. National Health and Nutrition Examination Survey.

For example, those of less means exhibit higher levels of lead and cadmium, thanks to a greater prevalence of smoking and exposure to industrial workplaces among the poor. And the more well-off, who are free to spend leisure hours in the sun, have higher levels of benzophenone-3, also known as oxybenzone—a main ingredient in sunscreen that some suspect encourages skin cancer.

As Quartz sums it up, “this work establishes that in some ways, in moving up the economic ladder Americans are simply trading one set of environmental toxins for another.”

How’s that for a reframing of progress and the American Dream? Work hard, and your kids can consume an entirely different class of chemicals than your parents did!
