Researchers have found around half the population don't have the right genes to fully benefit from eating the green vegetable. They retain the cancer fighting chemical sulforaphane for only a few hours.

In the meantime researchers from the Institute of Food Research (IFR) say that eating larger portions may be the best way to compensate. Lead scientist Professor Richard Mithen said: "Eating a few portions of broccoli each week may help to reduce the risk of cancer". And pigs might fly
