I know people love corn flakes and do not want to give them up. Someone sheepishly emailed me asking if cornflakes have high levels of phytic acid / phytates. The reader is concerned about phytic acid because it can interfere with your body's absorption of important body-building minerals. Typically, corn is pretty high in phytic acid and it is actually hard to reduce the levels in home cooking.
I don't know what Michigan-based food scientists do to make Corn Flakes, but whatever it is that they are doing, it appears to reduce the phytic acid in their product. In a 1987 review article by Harland and Oberleas they provide the phytate levels for Corn Flakes. Just to humor ourselves we can compare it to some of our other favorite corn products:
Kellogg's Corn Flakes: 70 mg/ 100 grams
Kellogg's Corn Pops: 94 mg/ 100 grams
Doritos Corn Chips: 635 mg/ 100 grams
Fritos Corn Chips: 506 mg/ 100 grams
Quaker Corn Meal: 943 mg/ 100 grams
