UK science has led to a new variety of broccoli with higher levels of a key phytonutrient, to be sold in all major UK supermarkets from next week.
The new broccoli, Beneforté, was developed from publicly-funded research at two of the UK's world-leading biological research institutes: the Institute of Food Research and the John Innes Centre. They both receive strategic funding from the government-sponsored Biotechnology and Biological Sciences Research Council (BBSRC). Beneforté was initially trialled in Marks and Spencer from October last year.
IFR scientists are continuing to develop our understanding of what it is about broccoli, a type of brassica, that makes it a particularly healthy food. Studies show that people with a higher proportion of brassicas in their diet have lower risks of some diseases. Ongoing research is revealing exactly how brassica phytonutrients exert their effect on human health.
The Italian-sounding name, Beneforté, is a nod to origins of the research. It began when Professor Richard Mithen began to analyse wild brassicas from Italy for glucosinolates.
"We started a programme to explore the genetics of glucosinolates as well as to develop broccoli breeding lines with high levels of these compounds."
Research at IFR and elsewhere in the UK and US suggested that a particular compound, sulforaphane, derived from a glucosinolate called glucoraphanin, had certain anti-cancer and health-promoting properties.
The researchers used conventional breeding techniques to develop the new broccoli, which contains two to three times the level of glucoraphanin than standard broccoli. Research continues, in collaboration with the Norfolk and Norwich University Hospital, to explain the link between eating broccoli and lower rates of heart disease and some forms of cancer.
"The results of years of study, at IFR and elsewhere, of the role of glucoraphanin in the diet are now coming to fruition," said Professor David Boxer, Director of IFR.
"Our research can make it possible for new healthy and safer food products to be developed, reducing the need for medical and social intervention. It can provide new insights into how certain food components moderate our risk of disease."
Dr Jan Chojecki, Managing Director of PBL, the tech transfer company that helped move the research beyond the lab said: "The development of Beneforté has pioneered a new and distinctive type of an already popular fresh vegetable. It is great that this British product is now widely available to everyone in the UK".
Professor Douglas Kell, BBSRC Chief Executive, said:"The roll-out of Beneforté broccoli to supermarkets across the UK is great news for the public and UK science alike. This development follows years of publically funded research to understand the fundamental bioscience of broccoli and the compounds within it. This knowledge has now been translated into a commercial product, with significant potential health benefits, available to all."
Research highlights - health benefits
Broccoli is the only commonly eaten vegetable that contains meaningful quantities of glucoraphanin. This naturally occurring compound is converted in the gut to the bioactive compound sulforaphane, which then circulates in the bloodstream. A large body of scientific evidence indicates that sulforaphane is likely to have beneficial effects such as reducing chronic inflammation, stopping uncontrolled cell division associated with early stages of cancer, and inducing antioxidant enzymes (ref 1).
This research on sulforaphane could explain why people who eat a few portions of cruciferous vegetables such as broccoli every week, have a lower risk of chronic diseases such as cancer and heart disease (ref 2). Studies at IFR have already shown that eating the new broccoli results in two to four times the level of sulforaphane in the blood compared to normal broccoli (ref 3).
In collaboration with the Norfolk and Norwich University Hospital, the IFR scientists found that men who ate a broccoli-rich diet experienced changes in the activity of genes associated with tumour survival and growth (ref 4). These changes were consistent with studies that suggest men who eat broccoli-rich diets have a reduced risk of aggressive prostate cancer (ref 5). Prostate cancer is the most common non-skin cancer for males in western countries.
