An Apple a Day Lowers Level of Blood ChemicalLinked to Hardening of the Arter ies, ResearchSuggestsOct. 2, 2012 — Eating an apple a day might in fact helpkeep the cardiologist away, new research suggests.

In a study of healthy, middle-aged adults, consumption ofone apple a day for four weeks lowered by 40 percentblood levels of a substance linked to hardening of thearteries. Taking capsules containing polyphenols, a type ofantioxidant found in apples, had a similar effect.

The study, funded by an apple industry group, found thatthe apples lowered blood levels of oxidized LDL -- low-density lipoprotein, the "bad" cholesterol. When LDLcholesterol interacts with free radicals to become oxidized,the cholesterol is more likely to promote inflammation andcan cause tissue damage.

"When LDL becomes oxidized, it takes on a form that begins atherosclerosis, or hardening of the arteries," saidlead researcher Robert DiSilvestro, professor of human nutrition at Ohio State University and a researcher at theuniversity's Ohio Agricultural Research and Development Center. "We got a tremendous effect against LDLbeing oxidized with just one apple a day for four weeks."

The difference was similar to that found between people with normal coronary arteries versus those withcoronary artery disease, he said. The study is published online in the Journal of Functional Foods and will appear in a future print edition.

DiSilvestro described daily apple consumption as significantly more effective at lowering oxidized LDL than otherantioxidants 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.

DavidTypewritten TextThis is the most important study on cardiovascular health you'll read about this year. A growing number of experts now understand that cholesterol does not cause heart disease. Oxidation causes heart disease- specifically, oxidation of LDL. Your cholesterol levels don't matter. The evidence is "abundantly clear." (Cardiovascular Research 68 (2005) 353 – 354.)

DavidTypewritten TextIn this new clinical study, apples, and capsules of apple polyphenols, lower oxidation of LDL and prevent hardening of the arteries. Dr. DiSilvestro not only has the right target, he reports that apple polyphenols are superior to green tea, curcumin, and other antioxidants he has tested at preventing oxLDL. Heart disease is the number one killer of Americans. Now you know how to stop it.
