Eating broccoli may protect against heart disease, US research suggests.
Rats were fed an extract of the vegetable for a month, and the effect on their heart muscle was measured.
Compared with animals whose diet did not change, the hearts of the broccoli rats functioned better and displayed less damage when deprived of oxygen.
The Journal of Agricultural and Food Chemistry study suggests broccoli may trigger production of proteins which protect against heart damage. The health benefits of broccoli have been widely touted, particularly in regard to its potentially protective qualities against cancer.
But working out both if and how this may be the case has proved a challenge.
Now researchers at the cardiovascular research centre at the University of Connecticut believe they have at least shown how the benefits may work in animal hearts.
