Health benefits of potatoes

Potatoes are without a doubt the nation’s most popular vegetable with a staggering 1337 million potatoes consumed worldwide each year. The humble potato is the fifth most important crop world wide after wheat, corn, rice and sugar cane. And is a staple food source for rich and poor alike. Currently there are 575 known varieties of potato and the list is still growing.

It was the South Americans that dug up the first potato around 6,000 years ago in the foothills of the Andes Mountains in Peru. Belonging to the nightshade (Solanaceae) family of plants, many of the varieties of potato are in fact poisonous. This is due to high levels of a chemical compound known as alkaloids. The American Indians managed to identify a variety known as diploid that was the first ever cultivated potato.

It wasn’t until the 1600s that potatoes first made it across the Atlantic to Europe and a further 300 years until large scale production began with many of the old breeds not able to cope with the longer days and colder winters it took around 150 years of intense crossing and breeding to end up with the potato we all know and cherish today.
