An Apple a Day – Fact or Fiction

Last year I participated in a study here on campus regarding apples.  I had always wondered about the ‘Apple a day keeps the doctor away’ saying and I liked apples, so I thought, why not.  When I signed up for the study I was told that participants would be divided into four groups.  Group 1 would take a placebo each day; Group 2 would take a capsule each day containing polyphenols, a type of antioxidant found in apples; Group 3 would eat an apple each day; and Group 4 would not only eat an apple a day, but also apple sauce and drink a glass of apple juice.  Lucky me – I ended up in Group 4.  Let me just say, that was a lot of apple.

The study was held over a 4 week period.  Prior to starting the study a blood sample was taken and I was asked to spit in a cup.  After the 4 weeks another blood sample was taken and again I spit in a cup.  I wondered about the whole spitting in a cup thing, but having read the results of the study it now makes sense.

And the results, they were fairly significant.  Those individuals who consumed an apple a day for 4 weeks lowered by 40% the blood levels of oxidized LDL – “bad” cholesterol.  This is what contributes to the hardening of arteries.  As far as spitting in the cup, they also found that eating apples has some effect on the antioxidants in saliva which has implications for dental health.

It appears that ‘An Apple a Day’ could indeed keep the cardiologist away.  As for an apple, apple sauce, and apple juice – that was a bit much.
