Apparently, every person in the United Kingdom eats more than 200lbs of potatoes a year, and we produce 5.6m tonnes of the crop.
It was first brought into the country in 1584 by Sir Walter Raleigh.
The story goes that Queen Elizabeth I was given the leaves to eat, much to her displeasure.
Not off to a good start, but potatoes boomed in the Industrial Revolution when cheap, high-energy food was needed.
It has become a staple in our diet ever since, and we have to import some from other countries as we do not produce enough.
Potatoes contain some vitamins, but not so many as the sweet potato which you can use in the same way.
The sweet potato is a root vegetable that can be roasted, mashed and boiled but contains nearly 70 per cent of your daily required vitamin C, along with loads of vitamin A and magnesium.
The sweet potato is also classed as one of your five-a-day, unlike normal potatoes.
It is in our interest to introduce it into our diets – and it cooks just the same as a normal potato.
Here is a lightly-curried sweet potato dish that you can use as a side or main dish.
