Marion Nestle writes passionately about the negative effects the food industry has had on the health of consumers. She contends that the rise in obesity in America is the direct result of the $33 billion a year spent by the industry for marketing--in other words, getting people to eat more. She also claims that many food-industry experts --scientists, dietitians, nutritionists, and universities, not to mention the government--have been bought off by food companies.
