Nestle SA (NESN.VX) thinks it can turn around its U.S. frozen foods business despite recent sales declines driven by consumer perceptions that the products are not healthy, the company’s U.S. chief executive said in an interview. Nestle remains committed to investing in its frozen food brands, which include Stouffer’s and Lean Cuisine, Paul Grimwood told Reuters on Friday. The business is Nestle’s second-largest in the U.S., behind pet care.
