A San Diego mother is suing big cereal companies for misleading ads. Jennifer Hardee is suing Kraft, General Mills and Kellogg's. They've been advertising special "low-sugar" cereals. Hardee says she thought the cereals would be better for her kids. Then she learned the products have no more nutritional value than regular cereal. General Mills now says it never made any specific health claims. It just advertised the cereals as low in sugar.
