It's kind of self-evident, really!

So how do you gauge how much oil went into your food?

First check out how far it traveled. The farther it went, the more oil it required. Next, gauge how much processing went into the food. A fresh apple is not processed, but Kellogg's Apple Jacks cereal requires enormous amounts of energy to process. The more processed the food, the more oil it requires. Then consider how much packaging is wrapped around your food. Buy fresh vegetables instead of canned, and buy bulk beans, grains, and flour if you want to reduce that packaging.

You may think you're in the clear because you eat strictly organically grown foods. When it comes to fossil-fuel calculations though, that isn't relevant. However it is grown, a raspberry is shipped, packed and chilled the same way.

There is some energy savings in growing organically, but it's probably slight. According to a study by David Pimentel at Cornell University, 30 percent of fossil-fuel expenditure on farms growing conventional (nonorganic) crops is found in chemical fertilizer.

This 30 percent is not consumed on organic farms, but only if the manure used as fertilizer is produced very close to the farm. Manure is a heavy, bulky product. If farms have to truck bulk manure more than a few miles, the savings is eaten up in diesel-fuel consumption, according to Pimentel. ....
