But the day is also a chance to ask those who grow our food about how they ensure the health and welfare of their animals, or how they use chemicals to protect their crops.

Here are ten facts you could discover about East Anglian farming:

- Norfolk and Suffolk are responsible for 20pc of the UK's poultry, 25pc of its pig herd, 20pc of its vegetables and almost 50pc of its sugar beet.

- But the biggest land use in the east of England is for cereal crops like wheat and barley, which account for almost half of our agricultural fields.

- About 1kg of grain will be harvested from each square metre of wheat, which will make enough flour to make one large loaf of bread.

- East Anglia is renowned for the quality of its barley, much of which is malted and sent to some of the world's most famous breweries and distilleries.

- A square metre of barley will make enough malt to make 10 bottles of beer - or 265 packets of Maltesers.

- Some modern dairy farms use robots to milk their cows.

- British cows produce enough milk each year to fill 6,000 Olympic swimming pools.

- Hi-tech computerised tractors can drive themselves around the field, using satellites to map their route.

- British hens lay 10 billion eggs a year.

- A square metre of sugar beet will produce about 1.5kg of sugar. More than a third of the UK's sugar beet is grown in Norfolk and processed into Silver Spoon sugar at British Sugar's four factories, including at Cantley and Wissington.
