What’s in Your Food?

Caroline recently sent me an article about organic food from Consumer Reports. The article is a very interesting read since it details what is and is not allowed for foods labelled “organic,” and, more importantly, some efforts by big agribusinesses to undermine those rules in favor of profit. But I want to focus on two smaller quotes from the article. First,

Organic fruits and vegetables are farmed with botanical or primarily nonsynthetic pest controls quickly broken down by sunlight and oxygen, instead of long-lasting synthetic chemicals. Organic produce sometimes carries chemical residues because of pesticides that are now pervasive in groundwater and rain, but their chemical load is much lower.

According to the Environmental Working Group (EWG), a research and advocacy organization in Washington, D.C., eating the 12 most contaminated fruits and vegetables exposes you to about 20 pesticides a day on average. If you eat the 12 least contaminated, you’re exposed to about two pesticides a day.

Even eating the least contaminated food exposes you to, on average, multiple pesticides per day because the stuff is as much a part of groundwater and rain as, well, the water itself. Is that not shocking? This article sort of tosses it out there like they’re saying the sky is blue. But it’s why advocate organic foods even if the direct health impact over regular foods to me is minimal: it’s just getter for the Earth and for everyone in general.

The Difference Between Knowing and Truly Understanding

In grad school, I TA’d for a professor who claimed that students finished his class knowing genetics as well as those at Harvard. He gave out these detailed definitions for terms and made the students write them down verbatim. On the tests, he give them the definitions with some words missing, and they had to fill in the blanks. It struck as a very rote, grammar school type of pedagogy, and I’m not sure that any of the students came away from the course with a very deep understanding of genetics. After all, just because you can recite a definition doesn’t mean that you understand what you’re saying. It’s the difference between knowing and truly understanding.

I bring this up in response to a recent editorial in Wired, “Your Outboard Brain Knows All,” in which Clive Thompson talks about our increasing reliance on computers to store key facts. He cites a study that found a number of young people didn’t know their own phone number and instead had to look it up on their phones. I usually know my own number, but I was dating Caroline for years before I’d memorized hers. Moreover, I love looking stuff up on Wikipedia or IMDB. But Thompson raises a good question: “Does an overreliance on machine memory shut down other important ways of understanding the world?”
