So no one gets hurt!
Tamar is an interesting writer (her blog, the rest of her writing at the Post). She often takes a controversial subject in the world of food and does in-depth analysis on it (sort of like how the Do The Math blog does for alternative energy). In this article she looks at the value of salad, specifically the cost/benefit when including the farm and transportation costs. I knew things were bad, but didn’t realize how bad they were. She puts a comparison thus:
A head of iceberg lettuce has the same water content as a bottle of Evian (1-liter size: 96 percent water, 4 percent bottle) and is only marginally more nutritious [lettuce is 95 to 97 percent water].
This is an interesting image from the article:
