The Academy maintains that being at the "same table" with food companies is important in order to exert a positive influence over their products and message, although critics describe this as an "unhealthy alliance" between the Academy and junk food companies. The accusation is that despite what good may come of such programs, it ultimately whitewashes (similar to the greenwashing efforts of environmentally irresponsible companies) the brand's role in the country's food ecosystem. Watchdogs note that the Academy rarely criticizes food companies, believing it to be out of fear of "biting the hand that feeds them." Nutrition expert Marion Nestle opined that she believed that as long as the AND partners with the makers of food and beverage products, "its opinions about diet and health will never be believed be independent." Public health lawyer Michele Simon, who researches and writes about the food industry and food politics, has voiced similar concerns stating, "AND deeply embedded with the food industry, and often communicate[s messaging that is industry friendly." A 2011 survey, found that 80% of Academy members are critical of the Academy's position. They believe that the Academy is endorsing corporate sponsors and their products when it allows their sponsorship.
