The Kellogg Co.-commissioned consumer survey of 1,006 U.S. adults, conducted last November by Caravan Survey, also indicates nearly 20 percent incorrectly believe meat, seafood and dairy foods are good sources of fiber.
Eight in 10 Americans say they make a conscious effort to include fiber in their diet and get enough of it, but in reality fewer than one in 10 actually get the recommended daily intake of 25 grams, the survey indicated.
Fiber is in fruits, vegetables, beans and legumes, but when it comes to whole grains, the fiber content varies. The recently federally approved dietary guidelines recommend people check nutrition labels to compare whole-grain products to find choices higher in dietary fiber. In general, foods with 3 grams of fiber per serving are considered a good source and foods with 5 grams are an excellent source, the U.S. Food and Drug Administration says.
