McDonald’s made a move in the right direction by stopping sales of ‘supersized’ French fries and soft drinks. I hope it is an indication that the company is paying more attention to obesity, heart disease, and other diet-related diseases. McDonald’s competitors should immediately follow suit and begin normal-sizing their largest menu items.

However, the last time McDonald’s made a big public-relations splash about nutrition—by announcing that it would switch to a healthier frying oil—it quietly went back on its word. If McDonald’s truly cared about its customers’ hearts and arteries, it would reformulate its cooking oil to eliminate trans fat.

And if McDonald’s wanted to encourage healthy lifestyles and boost sales of its most healthful products, it would also put calorie counts right on its menu boards. After all, a large order of McDonald’s French fries has 540 calories, and a medium fries has 450 calories. Consumers who are trying to maintain a healthful weight deserve to have that kind of information available while waiting in line.
