The proverb, "An apple a day keeps the doctor away", evolved from a 19th century Welsh saying intended to convey the health benefits of eating the fruit.
Apple trees are one of the oldest, if not the oldest, trees to be domestically cultivated, and today there are over 7,500 different cultivars of apples, produced in countries all over the world.
Apples are often eaten raw and, although lower in vitamin C, and other essential nutrients, than many other fruits, do contain high levels of dietary fibre, as a variety of different phytochemicals in the peel.
Why red apples, though? Well, there doesn't seem to be a reason. Apples come in red, green, pink and yellow, as well as russetted and bi and tri-coloured. There are therefore many different red apples, such as the Red Delicious, which is one of the more common ones.
