Oatmeal, that sturdy breakfast food from your grandmother's kitchen, has a lot going for it. Not only is it a fine way to start the day, but it can also really bring down your bad LDLcholesterol levels without lowering your good cholesterol. The same goes for oat bran, which is in some cereals, baked goods, and other products.
You’ve probably heard of triglycerides, and you’ve probably also heard that consistently high blood levels of triglycerides can be a bad thing.
But what aretriglycerides, exactly? Why would your doctor shake his head if your cholesterol report says that your triglycerides are high? And what do they have to do with diabetes and a group of worrisome symptoms called the “metabolic syndrome?”
Oatmeal is full of soluble fiber, which we know lowers LDL levels. Experts aren't exactly sure how, but they have some ideas. When you digest fiber, it becomes gooey. Researchers think that when it's in your intestines, it sticks to cholesterol and stops it from being absorbed. So instead of getting that cholesterol into your system -- and your arteries -- you simply get rid of it as waste.
What's the Evidence?
There's plenty of evidence that eating oatmeal lowers cholesterol levels. It's such a well-accepted belief that the FDA gave it the status of a "health claim" in 1997. This allows manufacturers to advertise the heart-healthy benefits on boxes of oatmeal and other products.
Some studies have shown that oats, when combined with other cholesterol-lowering foods, can have a big effect on cholesterol levels. In a study published in the American Journal of Clinical Nutrition, researchers tested cholesterol-lowering drugs against cholesterol-lowering foods in a group of thirty-four adults with high cholesterol. Oat products were among the chosen foods. The results were striking. The diet lowered cholesterol levels about as well as cholesterol drugs.
Getting Oatmeal Into Your Diet
It's fairly simple to work oatmeal into your meal plan. Start with the obvious: enjoy hot oatmeal in the morning.
"Oatmeal makes a filling, healthy breakfast," says Ruth Frechman, RD, a spokeswoman for the American Dietetic Association. She suggests that you add bananas or walnuts. If you're not so keen on hot oatmeal, try a cold cereal that's made from oat bran.
But oatmeal isn't only for breakfast. "Ground oatmeal can be added to any food," Frechman tells WebMD. You can add it to soups and casseroles. You can add some to breadcrumbs when you coat food for cooking. You can also add it to many recipes for baked foods. For instance, the American Dietetic Association suggests swapping one-third of the flour in recipes with quick or old-fashioned oats.
