This one is apparently so complicated that the Whole Grain Council had to create a web page called "Identifying Whole Grain Products." The key thing, though, is that if bread is "whole grain" or "made with whole grains" it could be white bread with a bit of quinoa sprinkled in. If you want to be sure that you’re actually getting some health benefits in there, a "100% whole grain" stamp is really the only safe bet.
"Organic" processed food
This is a strange one, since the Department of Agriculture has an established definition of organic food, and if something has the USDA Organic seal, it's actually been verified as organic. BUT: when it comes to processed foods, or products with several ingredients, "organic" doesn’t necessarily mean "100% organic." Up to 5% of a product's ingredients (not including salt and water) may be nonorganic, and a package can still have that pretty "Organic" label slapped on it.
"May reduce the risk of..."
When a food company wants to say that a food might prevent a specific disease, that’s called a "health claim." Luckily, the FDA has come up with very concrete sentences that food companies can put on packages. For example, here’s a trendy one that they label with an exciting "NEW" on their site: "Psyllium husk may reduce the risk of type 2 diabetes, although the FDA has concluded that there is very little scientific evidence for this claim."
