Fruit and vegetables may be enough to lower risk of early death

Eating five daily portions of fruit and vegetables is associated with a lower risk of death from any cause, particularly from cardiovascular disease, but beyond five portions appears to have no further effect, finds a new study.

These results suggesting that seven or more daily portions of fruits and vegetables were linked to lowest risk of death.

There is growing evidence that increasing fruit and vegetable consumption is related to a lower risk of death from cardiovascular disease and cancer.

So a team of researchers decided to examine the association between fruit and vegetable intake and risk of all-cause, cardiovascular, and cancer deaths.

They analysed the results of sixteen studies involving a total of 833,234 participants and 56,423 deaths. Higher consumption of fruit and vegetables was significantly associated with a lower risk of death from all causes, particularly from cardiovascular diseases.

Average risk of death from all causes was reduced by 5% for each additional daily serving of fruit and vegetables, while risk of cardiovascular death was reduced by 4 percent for each additional daily serving of fruit and vegetables.

But the researchers identified a threshold around five servings per day, after which the risk of death did not reduce further.

In contrast, higher consumption of fruit and vegetables was not appreciably associated with risk of death from cancer. The researchers suggest that, as well as advice to eat adequate amounts of fruit and vegetables, the adverse effects of obesity, physical inactivity, smoking and high alcohol intake on cancer risk should be further emphasized.

The researchers say their study “provides further evidence that a higher consumption of fruits and vegetables is associated with a lower risk of mortality from all causes, particularly from cardiovascular diseases. The results support current recommendations to increase consumption of fruits and vegetables to promote health and longevity.
