Apples are light on vitamins but are good for phytochemicals which protect against cancer, heart disease, osteoporosis, allergies and more.
Apples also contain pectin, a soluble fibre that removes toxins from your gut.
The saying "An apple a day keeps the doctor away" was first recorded in 1860s in Wales. The original saying was "Eat an apple on going to bed, and you'll keep the doctor from earning his bread."
All sweet apples arose originally in a small area of Tian Shan on Kazakhstan's border with China. They then spread into Europe through the Middle East. It was the Romans who first introduced varieties that were sweeter and tastier.
The earliest known mention of apples in England was by King Alfred in about 885 AD and were introduced to North America in the 17th century.
