Eating five portions of fruits and vegetables daily may be enough to lower the risk of early death, particularly from cardiovascular disease, according to a new study.
The study, published in the British Medical Journal July 29, examined the potential relationship between fruit and vegetable consumption and risk of death from all causes, including cardiovascular disease and cancer.
Researchers from China and the U.S. analyzed the results of 16 different studies involving 833,234 participants and 56,423 deaths from cancer, cardiovascular deaths and other causes.
The study found each additional daily serving of fruits and vegetables decreased the risk of death from all causes by 5%.
Our study also showed that higher consumption of fruit and vegetables was associated with lower risk of mortality from cardiovascular disease, but not cancer, the researchers wrote.
In terms of total mortality reduction, the study also found a threshold of about five servings a day of vegetables and fruits after which the risk of death did not reduce further.
Those findings seemed to conflict with another recent study published in BMJs Journal of Epidemiology and Public Health, which suggested seven or more daily servings of fruits and vegetables were linked to lower risk of death.
