Multiple Choice

Choose the appropriate letter to identify the main idea implied by the paragraph. A recent survey revealed that 63 percent of Americans took a vitamin, mineral, or herbal supplement over a three-month period.Another survey showed that people decided to take these products based on information they got from their friends or family members, from magazines and advertisements, or from the products' labels themselves.These people rarely consulted their doctor.Instead, they relied on the accuracy of product labels to help them make purchasing decisions.Labels, however, can be deceptive.They do not always accurately reflect the ingredients in a bottle's contents.Furthermore, the Food and Drug Administration does not require scientific studies to prove the safety or effectiveness of supplements.This means that the medical community cannot verify that the supplements actually work.Even worse, physicians are treating more and more patients who experience adverse reactions from taking these products.St.John's wort, an herbal anti-depressant, can cause nerve damage.Ginseng, which is supposed to increase energy, can cause dangerous reductions in the blood sugar levels of diabetics.Ephedra, a popular diet aid, may cause strokes and heart attacks.Strong doses of chaparral, a therapeutic tea, can prove toxic and damage the liver.
