Foods that make up a low cholesterol diet can help reduce high levels

Changing what foods you eat can lower your cholesterol and improve the armada of fats floating through your bloodstream. Adding foods that lower LDL, the harmful cholesterol-carrying particle that contributes to artery-clogging atherosclerosis, is the best way to achieve a low cholesterol diet.

Add these foods to lower LDL cholesterol

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.

11 foods that lower cholesterol thumbnail
1. Oats. An easy first step to lowering 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.)
2. 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.
3. Beans. Beans are especially rich in soluble fiber. They also take a while 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.
4. Eggplant and okra. These two low-calorie vegetables are good sources of soluble fiber.
5. 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.
6. 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.
7. Apples, grapes, strawberries, citrus fruits. These fruits are rich in pectin, a type of soluble fiber that lowers LDL.
8. 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%.
9. 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 2 1/2 cups of soy milk) can lower LDL by 5% to 6%.
10. 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.
11. 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.

Putting together a low cholesterol diet

When it comes to investing money, experts recommend creating a portfolio of diverse investments instead of putting all your eggs in one basket. The same holds true for eating your way to lower cholesterol. Adding several foods to lower cholesterol in different ways should work better than focusing on one or two.
A largely vegetarian "dietary portfolio of cholesterol-lowering foods" substantially lowers LDL, triglycerides, and blood pressure. The key dietary components are plenty of fruits and vegetables, whole grains instead of highly refined ones, and protein mostly from plants. Add margarine enriched with plant sterols; oats, barley, psyllium, okra, and eggplant, all rich in soluble fiber; soy protein; and whole almonds.
Of course, shifting to a cholesterol-lowering diet takes more attention than popping a daily statin. It means expanding the variety of foods you usually put in your shopping cart and getting used to new textures and flavors. But it's a "natural" way to lower cholesterol, and it avoids the risk of muscle problems and other side effects that plague some people who take statins.
Just as important, a diet that is heavy on fruits, vegetables, beans, and nuts is good for the body in ways beyond lowering cholesterol. It keeps blood pressure in check. It helps arteries stay flexible and responsive. It's good for bones and digestive health, for vision and mental health.

5 ways to keep your memory sharp


The way you live, what you eat and drink, and how you treat your body affect your memory as well as your physical health and wellbeing. Here are five things you can do every day to keep mind and body sharp.
Manage your stress. The constant drumbeat of daily stresses such as deadline pressures or petty arguments can certainly distract you and affect your ability to focus and recall. But the bigger problem is an ongoing sense of extreme anxiety—that can lead to memory impairment. If you don’t have a strategy in place for managing your stress, protecting your memory is one reason to get one. Deep breathing, meditation, yoga, and a “mindful” approach to living can all help.
Get a good night’s sleep. People who don’t sleep well at night tend to be more forgetful than people who sleep soundly. A good night’s sleep is essential for consolidating memories. The most common reason for poor sleep is insomnia—difficulty falling asleep or staying asleep. Unfortunately, many medicines used to treat insomnia can also impair memory and general brain function. That’s why it’s best to try improving your sleep habits first and turn to medication only if those steps don’t help. If you do need sleep aids, use the lowest dose for the shortest time needed to get your sleep back on track.
If you smoke, quit. Easier said than done, certainly, but if you need additional motivation, know that smokers have a greater degree of age-related memory loss and other memory problems than nonsmokers. People who smoke more than two packs of cigarettes a day at midlife have more than double the risk of developing dementia in old age compared with nonsmokers. However, those who stop smoking by midlife and those who smoke less than half a pack a day have a similar a risk of dementia as people who have never smoked.
If you drink alcohol, do so moderately. Drinking too much alcohol increases the risk for memory loss and dementia. People with alcoholism have difficulty performing short-term memory tasks, such as memorizing lists. Another type of memory loss associated with alcohol use is called Korsakoff’s syndrome. In this condition, long-term vitamin B1 deficiency combined with the toxic effects of alcohol on the brain can trigger sudden and dramatic amnesia. In some cases this memory loss is permanent, but if caught early, can be reversed to some degree.
Protect your brain from injury. Head trauma is a major cause of memory loss and increases the risk of developing dementia. Always use the appropriate gear during high-speed activities and contact sports. Wear seat belts when riding in motor vehicles. Car accidents are by far the most common cause of brain injury, and wearing seat belts greatly reduces the chances of severe head injury. Wear a helmet when bicycling, riding on a motorcycle, in-line skating, and skiing.
