Joseph Keenan, a cardiology researcher and prfessor emeritus at the University of Minnesota, has a love-hate relationship with statins. On the one hand, he prescribes them to many patients. On the other, he can't use them to control his own dangerously high cholesterol. Like many of the 25 percent or so of patients prescribed statins who abandon them within six months, Keenan has had unpleasant side effects, such as muscle spasms, and blood tests indicate muscle damage. "It came as a shock," he says of finding out he'd have to do without his Lipitor.
What recourse do people like Keenan have? Some doctors, such as Steven Nissen of the Cleveland Clinic are so convinced of statins' lifesaving power that they first require patients to try all six before considering them intolerant. Next, patients might try a nonstatin drug such as Zetia, which lowers cholesterol by inhibiting its absorption in the intestine. But there are other weapons besides drugs in the cholesterol wars. For those intolerant of statins - and for people taking them as well - the following strategies can help defeat unhealthful cholesterol.
The so-called Mediterranean diet, the DASH (Dietary Approaches to Stop Hypertension) diet, and the Ornish Diet (which is particularly low in meat and dairy) are variations on this approach. One study found that a balanced diet did just as well as a statin at reducing bad cholesterol. Dean Ornish, the founder of the Preventive Medicine Research Institute in Sausalito, California, has shown that hsi multipronged approach (diet, exervise, stress reduction, and social support), while not easy to maintain, can lower LDL by nearly 40 percent and even cause plaques in artiers to shrink - which not even statins have been proven to do.
Notable exceptions worth exploring include niacin, plant steols, and soluble fiber supplements. Though niacin can raise blood sugar and cause flushing, a daily dose can raise HDL levels by 15 to 35 percent and loewr LDL levels by about 20 percent. Niacin has a risk of side effects, however, especially when combined with a statin (page 42). A daily serving of plant sterols (about 2 grams), in fortified foods such as margarine, orange juice, and rice milk, can also lower LDL by about 15 percent. Eating plenty of soluble fiber, which occurs naturally in products such as oats, nuts, flax, and psylium husk and in dietary supplements such as Metamucil, can also drop LDL. Red rice yeast, a popular dietary supplement, also works. But be warned that it contains lovastatin, the active ingredient in Mevacor, a prescription statin, and is "essentially an unregulated statin," says Robert Vogel, a cardiologist at the University of Maryland.
Lifestyle interventions often don't work nearly as well as a statin can. Exercise, a better diet, and supplements can generally reduce bad cholesterol by 20 to 40 percent, compared with 60 to 70 percent for statins. But Keenan estimates that 70% of people with problematic cholesterol levels could gain control with lifestyle changes alone. He has. His LDL levels are down by about 60 percent thanks to diet, exercise, niacin, and other supplements. That's as good a job, he says, as Lipitor did.
