Apples Lower Blood Levels of Bad Cholesterol

 Apples Lower Blood Levels of Bad Cholesterol

Apple consumption lowers the blood levels of a substance linked to hardening of the arteries, finds recent study.

Taking capsules containing polyphenols, a type of antioxidant found in apples, had a similar, but not as large, effect.

The study, funded by an apple industry group, found that the apples lowered blood levels of oxidized LDL-low-density lipoprotein, the "bad" cholesterol.

When LDL cholesterol interacts with free radicals to become oxidized, the cholesterol is more likely to promote inflammation and can cause tissue damage.

"When LDL becomes oxidized, it takes on a form that begins atherosclerosis, or hardening of the arteries," said lead researcher Robert DiSilvestro, professor of human nutrition at Ohio State University and a researcher at the university's Ohio Agricultural Research and Development Center.

"We got a tremendous effect against LDL being oxidized with just one apple a day for four weeks," he added.

The difference was similar to that found between people with normal coronary arteries versus those with coronary artery disease, he said.

DiSilvestro described daily apple consumption as significantly more effective at lowering oxidized LDL than other antioxidants he has studied, including the spice-based compound curcumin, green tea and tomato extract.

"Not all antioxidants are created equal when it comes to this particular effect," he said.

For the study, the researchers recruited nonsmoking healthy adults between the ages of 40 and 60 who had a history of eating apples less than twice a month and who didn't take supplements containing polyphenols or other plant-based concentrates.

In all, 16 participants ate a large Red or Golden Delicious apple purchased at a Columbus-area grocery store daily for four weeks; 17 took capsules containing 194 milligrams of polyphenols a day for four weeks; and 18 took a placebo containing no polyphenols. The researchers found no effect on oxidized LDLs in those taking the placebo.

"We got a tremendous effect against LDL being oxidized with just one apple a day for four weeks," DiSilvestro said.

"We think the polyphenols account for a lot of the effect from apples, but we did try to isolate just the polyphenols, using about what you'd get from an apple a day.

"We found the polyphenol extract did register a measurable effect, but not as strong as the straight apple. That could either be because there are other things in the apple that could contribute to the effect, or, in some cases, these bioactive compounds seem to get absorbed better when they're consumed in foods," he maintained.

Still, DiSilvestro said polyphenol extracts could be useful in some situations, "perhaps in higher doses than we used in the study, or for people who just never eat apples."

The study also found eating apples had some effects on antioxidants in saliva, which has implications for dental health, DiSilvestro said.

He hopes to follow up on that finding in a future study.

The study has been published online in the Journal of Functional Foods.
