Fortified cereal may be too much of a good thing

CHICAGO (WLS) -- Children eating a bowl of fortified breakfast cereal may be getting too much of a good thing.

A new report says that "millions of children are ingesting potentially unhealthy amounts" of Vitamin A, Zinc and Niacin, with fortified breakfast cereals the leading source.

The report by the Environmental Working Group in Washington says outdated nutritional labeling rules and misleading marketing by food manufacturers who use high fortification levels to make their products appear more nutritious is behind the risk.

When combining food intake and vitamin supplements, the report calculates that millions of American children are getting amounts of certain vitamins that are too high.
