Kellogg's makes Crispix cereal, introducing the brand in 1983 in an effort to compete with the popular Chex cereal made by Ralston Purina. The hexagonal-shaped cereal forms a lattice pattern on both sides, one of which is crispy rice and the other crunchy corn.
A 1-cup serving of Crispix contains 110 calories, no fat or cholesterol, 25 grams of carbohydrates and 2 grams of protein. It provides 45 percent of the daily recommended value for iron and 70 percent of the value for folic acid. Other Kellogg's cereals include Corn Flakes, Mini Wheats, Corn Pops and Rice Krispies. Others include Frosted Flakes and Raisin Bran.
