Oranges, grapes and carrots may contain cancer-fighting compounds that closely resemble those used in licensed drugs, research suggests.
A study found that out of more than 7,900 molecules within fruits and vegetables, 110 have the potential to battle tumours. This was based on the molecules' likeness to compounds found in existing anti-cancer medications.
Fruits and vegetables are rich in antioxidants called flavonoids, which give them their colour.
Flavonoids may help prevent cancer by suppressing inflammation, controlling cell replication and even inducing tumour 'suicide'.
