Seager Spencer L. Seager is a professor of chemistry at Weber State University, where he served as chemistry department chairman from 1969 until 1993. He teaches general chemistry at the university and is also active in projects to help improve chemistry and other science education in local elementary schools. He received his B.S. degree in chemistry and Ph.D. degree in physical chemistry from the University of Utah. Other interests include making minor home repairs, reading history of science and technology, listening to classical music, and walking for exercise. Michael R. Slabaugh Michael R. Slabaugh is a senior fellow at Weber State University, where he teaches the year-long sequence of general chemistry, organic chemistry, and biochemistry. He received his B.S. degree in chemistry from Purdue University and his Ph.D. degree in organic chemistry from Iowa State University. His interest in plant alkaloids led to a year of postdoctoral study in biochemistry at Texas A&M University. His current professional interests are chemistry education and community involvement in science activities, particularly the State Science and Engineering Fair in Utah. He also enjoys the company of family, hiking in the mountains, and fishing the local streams. iv About the Authors UUnnlleessss ootthheerrwwiissee nnootteedd aallll aarrtt oonn tthhiiss ppaaggee ©© CCeennggaaggee LLeeaarrnniinngg 22001144 Copyright 2012 Cengage Learning.

Tannins found in tea and phytates found in legumes and wheat bran may also impair iron absorption by chelating iron, preventing its absorption. Ascorbic acid (vitamin C) enhances absorption by reducing ferric to ferrous iron and chelating ferrous iron, improving its absorption at the higher pH of the regions of the small intestine located farthest from the stomach. Calcium supplements and dairy foods also impair iron absorption. Ferrous iron can also interact with several types of medications including the antibiotics ciprofloxacin and tetracycline, and thyroid medication. It impairs their absorption and thereby potentially reduces their effectiveness as medications. Calcium, also found in both dairy foods and some supplements, has several food and drug interactions. Like iron, calcium is only absorbed in ionic form. It too requires an acidic environment for optimal absorption, particularly when it is in the calcium carbonate form. This form is best taken with meals. Unlike iron, more calcium is absorbed in the parts of the small intestine located farthest from the acidic stomach. As a result, acid blocking medications are not as detrimental to absorption as they are for iron. But calcium citrate, which is more soluble at a neutral pH, may still be the preferable form for those with compro- mised levels of stomach acid. Phytates and oxalic acid, found in spinach, rhubarb, collard greens, sweet potatoes and beans bind calcium, creating insoluble complexes that cannot be absorbed. Calcium can also decrease the absorption of several medications including quinolone antibiotics, tetracycline, and thyroid replacement medication. Unlike iron and calcium which interact with medications by preventing their absorption, grapefruit interacts with numer- ous medications through its effect on drug metabolism. A flavonoid compound in grapefruit inhibits an enzyme, cytochrome P450 3A4, that is important for the degradation of numerous drugs. Since less of the drug is broken down when consumed with grapefruit or grapefruit juice, more of the drug is bioavailable, which can potentially lead to toxic levels in some cases. In addition to several of the cholesterol reducing statin medications, other drugs affected this way include several blood pres- sure lowering medications, the anti-retroviral medication saquinavir, and the immunosuppressive medication cyclosporine. St. John’s wort, a popular herbal supplement often used for the treatment of mild depression, may enhance rather than suppress the cytochrome P450 34A system in a clinically relevant manner, potentially reducing the effectiveness of several HIV medications, immunosuppressive medications, and even cancer treatment drugs. There are numerous other food, drug and supplement interactions. While not all of them may be clinically relevant, their presence underscore the importance of discussing both supplementation and diet with appropriate health care provider. This is especially true if you are taking prescription medication or supplements to treat a deficiency or medical condition. vi About the Cover Unless otherwise noted all art on this page © Cengage Learning 2014 Copyright 2012 Cengage Learning.
