It's an interesting question, and certainly there have been some companies over the years that have done some useful things. I think putting nutritional information on your website is a good thing for people who have the energy, enthusiasm, and savvy to get it.
There's kind of a limit to what industry can do without regulations. They're not going to do something that's going to hurt their bottom line. I don't think any amount of educating the McDonald's CEOs will convince them to switch to whole wheat buns, for instance. That would be important.
Some companies have done some important things recently, or at least have announced plans to. Walmart in the United States, which is a much bigger player in the grocery market there, has said they're going to set specifications for their suppliers to reduce the amount of sodium and trans fat in those products if they want them to be sold in their stores. I don't know who's going to monitor that. One of the distinctive things about that chain is that they don't share their sales data with ACNielsen, so it would be difficult for anybody on the outside to evaluate whether they're succeeding. However, at least it's a positive sentiment.
