A new type of broccoli that its growers claim could help slow the spread of cancer is being rolled out to the multiples following successful trials in M&S last year.

Beneforté went into Asda last week and is to roll out into Tesco, Sainsbury’s, The Co-op, Morrisons and Waitrose. It contains up to three times more glucoraphanin than standard broccoli.

Glucoraphanin is converted into a compound in the gut that studies indicate can help reduce chronic inflammation and slow cancer.

Grown by Produce World, Kettle Produce and Staples, Beneforté was developed by the Institute of Food Research and the John Innes Centre.
