America’s growing hunger for protein has whetted Jeffrey Ettinger’s appetite as well. In June, Hormel Foods agreed to buy CytoSport for $450 million, adding Muscle Milk and 100% Whey protein powder to its stable of brands, which include Spam, Dinty Moore stew, and other processed meat labels. Ettinger’s acquisition is part of a larger diversification effort at Hormel. Last year, the company bought Skippy peanut butter from Unilever for about $700 million. —J.A.
