Pandora's Lunchbox: How Processed Food Took Over the American Meal / Melanie Warner

Q&A with Melanie Warner

Q. What inspired you to want to explore the subject of processed foods?

A. The idea for a book crystallized for me not long after I began writing about the food and beverage industries in the mid-2000s. I went to a trade show called IFT (Institute of Food Technologists), one of the food industry s largest gatherings. Inside a massive convention center, there were people selling things like micro-particulated whey protein, inner pea fiber and starches that had been modified to mimic fat or dietary fiber. Companies talked about food as an application, as if it was a piece of software you put together. It seemed to me that our food had become vastly more technical and complicated than we realized, and we had little idea about what happens to it after it leaves the farm. This was the story I wanted to tell. Because in order to make good food choices, we first need to know what we re eating.

Q. What should everyone know about processed foods?

A. Processed food represents an entirely new way of eating for us as human beings. Our diets have changed more in the last 100 years than they have in the last 10,000. So much of what we see in the middle aisles at grocery stores and on fast food menu boards simply didn t exist a century ago.

This is a concern because, while the technology for processing food has advanced by leaps and bounds, our human biology hasn t. The way our bodies handle food is stuck somewhere in the Stone Age, long before there was sugary boxed cereal, chicken nuggets and frozen dinners. Much of what we eat is now deeply out of synch with our biology.

Q. What surprised you the most in your research?

A. Where vitamins come from (many of them come from China and are derived from starting ingredients like sheep grease) and how prevalent soybean oil is in our diets (10% of total calories) and the health implications of that.

Q. How has your behavior changed since writing the book? Do you eat differently? Do you feed your children differently?

A. Although I generally follow my own advice a diet with fresh, real foods at its foundation I do eat processed foods, as do my kids. But the book has made me a little more careful of my choices. When you stare at ingredient lists long enough, the siren call of quick, convenient, indulgent food often goes on mute. I have to say that I am no longer tempted by donuts! I also stopped my occasional purchase of fast food French fries because of what I uncovered about the toxic compounds formed in heated frying oil. And I realized there we certain things I was buying prepackaged that could in fact be made relatively easily at home, like homemade mac and cheese for the kids, made with real cheese instead of the powdered stuff in the box.
