Today, December 1st, is National Eat a Red Apple Day.

Apples have been associated with health from the phrase "An apple a day keeps the doctor away." This is believed to date back to 19th century Wales - back then, you really needed to keep the doctor away, as they were often more likely to kill you then many ailment.

There are a number of different apples that are, at least partially, red in colour, but the most distinctive is the Red Delicious (related to the Golden Delicious).
