Health-conscious Americans may try in theory to eat a balanced diet rich in essential minerals, but in the real world this can be a tough proposition. First, although we also need to eat fiber to stay healthy, lots of fiber tends to impair absorption of certain minerals, including zinc.
Second, some foods that contain desirable levels of minerals such as calcium and iron—that is, milk and red meat—also happen to have lots of artery-clogging saturated fat. And third, in some cases the soil that crops are grown in may lack key trace minerals, notably molybdenum and selenium.
