Scientists make super broccoli

[Guest guest]

I hope we will still be able to get the natural one.

Scientists are developing a " super-broccoli " which they hope will

help people ward off cancer.

 

Broccoli has anti-cancer properties but an Institute of Food Research

study has found some people's genetic make-up may minimise the

protection they get.

 

IFR scientists say creating broccoli containing more of the key

chemical - sulforaphane - may counter this effect.

 

They hope it will be ready in three years but recommend eating lots

of different green vegetables until then.

 

Genetic differences may affect how we absorb nutrients from our

food

 

Lead researcher Professor Richard Mithen said the key appeared to be

a gene called GSTM1, which about half the population don't have.

 

He said: " Some individuals, who lack the gene, appear to get less

cancer protection from broccoli than those who have the gene.

 

" Our studies suggest that this may be because, if you lack the gene,

you cannot retain any sulforaphane inside your body. It is all

excreted within a few hours.

 

" However, if you consume larger portions of broccoli, or broccoli

with higher levels of sulforaphane, such as the 'super-broccoli', you

may be able to retain as much sulforaphane in your body as those who

have the gene.

 

" Eating larger portions may have additional benefits, since broccoli

is also a rich source of other vitamins and minerals. "

 

Broccoli belongs to the crucifer family of vegetables which includes

cabbage, cauliflower and Brussels sprouts.

 

These vegetables contain high levels of glucosinolates, which when

eaten break down to release isothiocyanates.

 

Evidence shows that these isothiocyanates, which include

sulforaphane, are among the most powerful anti-cancer agents in the

diet.

 

The " super-broccoli " variety contains 3.4 times more of the compound

than standard types.

 

The researchers suggest it might not all be bad news for those people

who lack the GSTM1 gene.

 

It was possible they gained more cancer protection from other types

of crucifers rather than broccoli, they said.

 

They said the best advice was to eat a mixture of different types of

crucifer vegetable.

 

Josephine Querido, of Cancer Research UK, said: " The research backs

current thinking that genetic differences may affect how we absorb

nutrients from our food.

 

" But only 16 people took part in Professor Mithen's study and this is

too small a number from which to draw specific conclusions.

 

" We know that a healthy balanced diet is an important factor in

preventing cancer, especially cancers of the digestive system.

 

" But when it comes to food, there is no one particular 'super' fruit

or vegetable that will protect you from cancer.

 

" Experts have proven that the best way to reduce your risk of many

cancers is to eat a healthy balanced diet.

 

" This should include at least five portions a day of a variety of

fruit and vegetables. "
