Diabetes affects about 3.7 million people in the UK, according to the NHS.
About 90 per cent of all cases are type 2 diabetes.
The condition is caused by the pancreas not producing enough of the hormone insulin, or the body not reacting to insulin.
Diabetes symptoms include blurred vision, feeling constantly thirsty, and having cuts or wounds that take longer to heal than expected.
You could lower your risk of high blood sugar by eating more strawberries, nutritionists have claimed.
Diabetes type 2 symptoms: Strawberry diet lowers risk of high blood sugar signs
Strawberries could help to prevent high blood sugar in diabetes patients, according to Diabetes.co.uk.
They contain a group of compounds, known as anthocyanins.
The anthocyanins are responsible for giving strawberries their bright red colour, but could also protect against diabetes.
Eating just 160g of anthocyanins twice a day could reduce insulin resistance by about 13 per cent, scientists have revealed.
You could also lower your fasting glucose levels by almost 10 per cent by eating more strawberries, they claimed.
