The usda recommends that whole grains make up at least what percentage of our daily grain intake?

The most recent Dietary Guidelines for Americans, released in January 2011, recommend that all adults eat at least half their grains as whole grains – that’s at least 3 to 5 servings of whole grains. Even children need 2 to 3 servings or more. Recommendations in Canada’s Food Guide are almost exactly the same. (Not surprising, since the human body changes little from country to country!)

Hope this help 

Ok, before buying a burger. think of you diet and calories. how many calories are you suppose to eat a day. and look at how much fat, calories, salt is in it. if it is ok to you, then buy it. but if you think that it's to much fat and salt for you. don't buy !
