Changing what you eat can lower your cholesterol and improve the armada of fats floating through your bloodstream.
In with the good
Different foods lower cholesterol in various ways. Some deliver soluble fiber, which binds cholesterol and its precursors in the digestive system and drags them out of the body before they get into circulation. Some give you polyunsaturated fats, which directly lower LDL. And some contain plant sterols and stanols, which block the body from absorbing cholesterol.
Oats. An easy first step to improving your cholesterol is having a bowl of oatmeal or cold oat-based cereal like Cheerios for breakfast. It gives you 1 to 2 grams of soluble fiber. Add a banana or some strawberries for another half-gram. Current nutrition guidelines recommend getting 20 to 35 grams of fiber a day, with at least 5 to 10 grams coming from soluble fiber. (The average American gets about half that amount.)
Barley and other whole grains. Like oats and oat bran, barley and other whole grains can help lower the risk of heart disease, mainly via the soluble fiber they deliver.
Beans. Beans are especially rich in soluble fiber. They also take awhile for the body to digest, meaning you feel full for longer after a meal. That’s one reason beans are a useful food for folks trying to lose weight. With so many choices — from navy and kidney beans to lentils, garbanzos, black-eyed peas, and beyond — and so many ways to prepare them, beans are a very versatile food.
Eggplant and okra. These two low-calorie vegetables are good sources of soluble fiber.
Nuts. A bushel of studies shows that eating almonds, walnuts, peanuts, and other nuts is good for the heart. Eating 2 ounces of nuts a day can slightly lower LDL, on the order of 5%. Nuts have additional nutrients that protect the heart in other ways.
Vegetable oils. Using liquid vegetable oils such as canola, sunflower, safflower, and others in place of butter, lard, or shortening when cooking or at the table helps lower LDL.
Apples, grapes, strawberries, citrus fruits. These fruits are rich in pectin, a type of soluble fiber that lowers LDL.
Foods fortified with sterols and stanols. Sterols and stanols extracted from plants gum up the body’s ability to absorb cholesterol from food. Companies are adding them to foods ranging from margarine and granola bars to orange juice and chocolate. They’re also available as supplements. Getting 2 grams of plant sterols or stanols a day can lower LDL cholesterol by about 10%.
Soy. Eating soybeans and foods made from them, like tofu and soy milk, was once touted as a powerful way to lower cholesterol. Analyses show that the effect is more modest — consuming 25 grams of soy protein a day (10 ounces of tofu or 2½ cups of soy milk) can lower LDL by 5% to 6%.
Fatty fish. Eating fish two or three times a week can lower LDL in two ways: by replacing meat, which has LDL-boosting saturated fats, and by delivering LDL-lowering omega-3 fats. Omega-3s reduce triglycerides in the bloodstream and also protect the heart by helping prevent the onset of abnormal heart rhythms.
Fiber supplements. Supplements offer the least appealing way to get soluble fiber. Two teaspoons a day of psyllium, which is found in Metamucil and other bulk-forming laxatives, provide about 4 grams of soluble fiber.
Out with the bad
Harmful LDL creeps upward and protective HDL drifts downward largely because of diet and other lifestyle choices. Genes play a role, too — some people are genetically programmed to respond more readily to what they eat — but genes aren’t something you can change. Here are some steps you can take:
Saturated fats. One way to lower your LDL is to cut back on saturated fat. Try substituting extra-lean ground beef for regular; low-fat or skim milk for whole milk; olive oil or a vegetable-oil margarine for butter; baked fish or chicken for fried.
Trans fats. Trans fats boost LDL as much as saturated fats do. They also lower protective HDL, rev up inflammation, and increase the tendency for blood clots to form inside blood vessels. The Institute of Medicine recommends getting no more than two grams of trans fats a day; less is even better.
Weight and exercise. Being overweight and not exercising affect fats circulating in the bloodstream. Excess weight boosts harmful LDL, while inactivity depresses protective HDL. Losing weight if needed and exercising more reverse these trends.

Young May Outgrow Bipolar Disorder
Young Adults May Outgrow Bipolar Disorder
30 Sep 2009Bipolar disorder, or manic-depression, causes severe and unusual shifts in mood and energy, affecting a person's ability to perform everyday tasks. With symptoms often starting in early adulthood, bipolar disorder has been thought of traditionally as a lifelong disorder. Now, University of Missouri researchers have found evidence that nearly half of those diagnosed between the ages of 18 and 25 may outgrow the disorder by the time they reach 30.
"Using two large nationally representative studies, we found that there was a strikingly high peak prevalence of bipolar disorders in emerging adulthood," said David Cicero, doctoral student in the Department of Psychological Sciences in the College of Arts and Science and lead author of the paper. "During the third decade of life, the prevalence of the disorder appears to resolve substantially, suggesting patients become less symptomatic and may have a greater chance of recovery."
By examining the results of two large national surveys, MU researchers found an "age gradient" in the prevalence of bipolar disorder, with part of the population appearing to outgrow the disorder. In the survey results, 5.5 to 6.2 percent of people between the ages of 18 and 24 suffer from bipolar disorder, but only about 3 percent of people older than 29 suffer from bipolar disorder.
"Young adults between the ages of 18 and 24 are going through significant life changes and social strain, which could influence both the onset and course of the disorder," said Kenneth J. Sher, Curators' Professor in the Department of Psychological Sciences and co-author of the study. "During this period of life, young adults are exploring new roles and relationships and begin to leave their parents' homes for school or work. By the mid 20s, adults have begun to adjust to these changes and begin to settle down and form committed relationships."
Researchers predict the prevalence of the disorder also could be affected by brain development, particularly the prefrontal cortex. The prefrontal cortex, the very front part of the brain, is thought to control perception, senses, personality and intelligence. In particular, it controls reactions to social situations, which can be a challenge for people with bipolar disorder.
"The maturing of the prefrontal cortex of the brain around 25 years of age could biologically explain the developmentally limited aspect of bipolar disorder," Cicero said. "Other researchers have found a similar pattern in young adults with alcohol or substance abuse disorders."
While some scholars suggest that the difference could be due to discounting factors such as early mortality, the sheer number of those who are recovering rules out this possibility, Sher said.
The study, "Are There Developmentally Limited Forms of Bipolar Disorder?" was published in the Journal of Abnormal Psychology. It was co-authored by Cicero, Sher and Amee Epler, a doctoral student in the Department of Psychological Sciences.
