People who are genetically susceptible to heart disease can lower their risk by eating plenty of fruit and raw vegetables, a study suggests.
It says five or more daily portions should be enough to counteract culprit versions of a gene on chromosome 9, thought to be possessed by a fifth of people of European ancestry.

The US researchers investigated more than 27,000 people for their work.
The findings were published in Plos Medicine journal.
These participants came from from around the globe, including Europe, China and Latin America.
The results suggest that individuals with high risk 9p21 gene versions who consumed a diet packed with raw vegetables, fruits and berries had a similar risk of heart attack as those with a low-risk variant of the same gene.
