Eating an apple a day might in fact help keep the cardiologist away, according 
to research from Ohio State University.
In a study of healthy, middle-aged adults, consumption of one apple a day for four weeks lowered by 40 percent blood levels of a substance linked to hardening of the arteries.
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,” lead researcher Robert DiSilvestro, professor of human nutrition at Ohio State University and a researcher at the university’s Ohio Agricultural Research & Development Center, said in a press release. “We got a tremendous effect against LDL being 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 with coronary 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 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.
DiSilvestro first became interested in studying the health effects of eating an apple a day after reading a Turkish study that found such a regimen increased the amount of a specific antioxidant enzyme in the body.
In the end, his team didn’t find the same effect on the enzyme, but was surprised at the considerable influence the apples had on oxidized LDL.
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.
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 was conducted as a master’s thesis by graduate student Shi Zhao, and was funded by a grant from the U.S. Apple Association/Apple Product Research and Education Council and a donation from Futureceuticals Inc. of Momence, IL.
Also involved in the study were associate professor Joshua Bomser and research associate Elizabeth Joseph, both in the Department of Human Nutrition, which is housed in the university’s College of Education and Human Ecology.
While Washington state apple shippers are wringing their hands over the crop 
and profits that could have been, apple haulers probably won’t notice a lot of difference this 2012-13 season, since even after a hail reduced crop, shipments will be right in there with the average for the past five years.
One difference however, are the possibilities truckers may face with claims, unless you make sure the buyers know what is being delivered. There could be some hail damaged apples shipped to market this year; ones that look a little roughed up on the outside, but the quality is supposed to be good on the inside.
The apples with damage from hail will have “dimples” that turn brown and have a russetted look.
Some orchards totally escaped damage from the July 20 hail storm, while others were hit with varying amounts of damage. Much of the hits were taken by the Red Delicious variety.
The five-year average for Washington state apple shipments has been 100 to 110 million cartons. Before the hail storm, shippers were looking to move as much as 120 million cartons of apples this season. Loading opportunities are still expected to be good, despite the predictions of 10 to 25 percent of the crop being lost.
Updates on the amount of damage to apples from the hail storm are expected to come out within the next week.
