Here's our take: Kudos to Panera for shining a light on some of the standard practices among commercial food suppliers -- such as adding titanium dioxide to mozzarella cheese in order to create an ultra-white appearance. Who needs bleach in their mozzarella, really?
Panera's head chef, Dan Kish, says that as he and his team pored over the hundreds of additives in the ingredients that Panera uses, they asked two questions: What is this? And why is it used?
When he realized that the titanium dioxide was used for cosmetic purposes, he said, "Let's just take it out."
Kish says he's not a scientist, so he doesn't want get into the debate over whether removing the additives makes the food more healthful, or less harmful. In any case, there's little evidence that many of the additives Panera is eliminating pose a measurable health risk at the amounts they're commonly used in food. We've reported, for instance, that there's little risk associated with azodicarbonamide, a chemical on the "no-no" list, despite its association as being the same compound that's in yoga mats.
Kish says he believes that the direction Panera is headed is driven much more by his philosophy of food and cooking. "We think a simplified pantry is a better pantry," he says.
Other Big Food companies like Nestle, Hershey and Kraft are also eliminating or cutting back on additives. And it's clear from survey data that more Americans favor such changes.
In January, Nielsen published a global survey showing that an increasing number of Americans say they want fresh, natural and minimally processed foods. What's more, 1 in 4 North Americans said they would pay a premium for foods that were "all natural" or contained no artificial colors.
But where Panera is not pushing new boundaries is its call to ditch trans fats. As we've reported, in 2006, the Food and Drug Administration required food companies to label the trans fats in their products. Since then, the entire food industry has cut back drastically on the use of partially hydrogenated oils. The Grocery Manufacturers Association estimates that food manufacturers have lowered the amounts of trans fats in their food products by over 73 percent.
So, on this particular ingredient, it's hard to give Panera credit for a change that has already swept through the entire industry.
And, here's one more hiccup in Panera's "no-no" list: The company says it will not use any high fructose corn syrup or artificial sweeteners — such as aspartame and Ace-K — in its menu items.
And yet it will continue to sell beverages, such as sodas and diet-colas, that contain these sweeteners. "It's a big omission," says Lisa Lefferts, a senior scientist at the Center for Science in the Public Interest.
Panera's Kish says the company is working with its beverage suppliers to move in this direction. So, he says, stay tuned.
