How an apple a day could keep the cardiologist away

A new study suggests that eating apples each day could significantly improve the heart health of middle-aged adults in just one month.
Those who ate a daily apple over four weeks lowered 'bad' cholesterol in the blood by 40 per cent - 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.  'Bad' cholesterol or low-density lipoprotein (LDL) can interact with free radicals to become oxidized, which can trigger inflammation and can cause tissue damage. 
Research leader, Professor Robert DiSilvestro, from Ohio State University, said: 'When LDL becomes oxidized, it takes on a form that begins atherosclerosis, or hardening of the arteries.
'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, funded by an apple industry group, is published online in the Journal of Functional Foods and will appear in a future print edition.
