Coca-Cola is sugar-loaded, "liquid candy" and has contributed mightily to the obesity epidemic, says CSPI. A can of Coke contains 9 teaspoons of sugar.

This classic McDonald's meal typifies many fast food meals. It's short on fruit and vegetables but bulging with calories, salt, saturated fat, added sugar, and white flour. These ingredients promote obesity, high blood pressure, and other diet-related diseases, the CSPI says.

What's the problem with salt? Americans get too much of it - from packaged foods, restaurant meals, and salt-"enhanced" meats and poultry. It's the single most harmful substance in our diet, says CSPI. The group blames excess sodium for more than 100,000 fatal heart attacks and strokes each year.

Cows that are raised in feedlots are typically given antibiotics to prevent sickness and growth hormones so that they can reach slaughter weight faster. The CSPI says feedlot beef is unhealthy for humans - high in saturated fat with possible traces of antibiotics.

Despite its name, Froot Loops don't actually contain any fruit - just sugar. The cereal is "gussied up with synthetic dyes," CPSI says, and is one of a host of junk foods marketed heavily to kids.

A nationwide salmonella outbreak that sickened more than 1,500 people in 2010 put Maine egg farm tycoon Jack DeCoster in the spotlight. His farms crammed birds in filthy cages with reckless disregard for consumers' health, says CSPI. The incident dramatized the need for tougher food-safety laws to clean up the whole food industry.

Interest groups in the soft drink, food processing, advertising and other industries can thwart important reforms of marketing to kids, food labeling, farm policies, and other issues, the CSPI says.

Taxpayers pay $6 billion a year in subsidies to companies that blend corn ethanol into gasoline - and for efforts to market billions of gallons of that gasoline a year. Using corn for fuel also leads to higher prices for corn and foods with corn ingredients, says the CSPI.

It's used in bread, pizza crusts, pasta, doughnuts, cakes, burritos, cookies, and dozens of other foods. White flour has spurred the obesity epidemic by adding more vitamin-depleted, fiber-poor calories to the diet, says the CSPI.

Vending machines that dispense soft drinks and candy make it all too easy to have an unhealthy diet 24/7. The CSPI calls them "ubiquitous, mute, metallic monsters."
