Iron deficiency in young kids is less common than it used to be, but you still want to be vigilant because it can lead to irreversible cognitive defects. The easiest way to ensure your kid gets the iron they need is with an iron-fortified whole grain cereal. Cheerios, Kix and Life all contain 80-100-percent of your kid’s recommended daily amount; if you’re more of a Whole Foods shopper, look for the Earth Best’s kid cereals. If you need more impetus for establishing a cereal habit in your kid, consider this: a study of kids between the ages of 9 and 18 found that cereal-eaters had diets that were lower in fat and cholesterol, higher in fiber, vitamins and minerals, not to mention lower body fat indexes. So, consider each box an investment in your kid’s long term health.
