Where do we get zinc?
In 1990,
meat & dairy products provided over 60% of the
zinc in the American diet (44% & 19% respectively).
Grain products were a close 3rd supplying the diet w/about 17% of the zinc recommended.
Foods that contain small
amounts of zinc, but are not considered good sources, can contribute significant amounts of zinc to an individual's diet if
these foods are eaten often, or in large amounts.
How can we get enough zinc?
Eating a variety of
foods that contain zinc is the best way to get an adequate amount. Healthy individuals who eat a balanced diet rarely need
supplements.
Intakes of zinc tend
to be low in relation to recommendations & there aren't that many foods that are really good sources; thus, it may take
special care to ensure an adequate intake.
The list of foods below
will help you select those that are good sources of zinc as you follow the Dietary Guidelines. The list of good sources was
derived from the same nutritive value of foods tables used to analyze information for recent food consumption surveys of the
U.S. Dept. of Agriculture, Human Nutrition Information Service.
