Consumers won't find any foods with artificial transfats in Whole Foods Market stores, the co-chief executive of the grocery chain told CNBC on Friday.

The assertion by Walter Robb of Whole Foods in a "Squawk Box" interview followed news that the Food and Drug Administration proposed banning transfats in processed food ranging from cookies to frozen pizza on safety concerns. The agency said Thursday that reducing the consumption of these fats could prevent 20,000 heart attacks and 7,000 deaths from heart disease a year.
