1-5 porties groenten en fruit per dag verlaagt doodgaan aan hart- en vaatziekten

Research Question:
Eating plenty of fruits and vegetables daily reduces the risk of all-cause mortality?

Study Design:
This overview article contained 16 prospective cohort studies with 56423 dead (11512 died from heart disease and 16817 died of cancer) under 833234 participants. The follow-up duration varied between 4.6 and 26 years.

All studies had corrected for age.
There was heterogeneity between the studies but no publication bias.

Results and conclusions:
The researchers found that a high fruit and vegetable consumption the risk of all-cause mortality (= death to all causes) significantly reduced.

The researchers found that increasing fruits and vegetables with 1 serving per day, the risk of all-cause mortality (= death to all causes) significantly with 5% [95% CI = 0.92 to 0.98, p = 0.001, I2 = 82%, p 0.001] reduced.

The researchers found that increasing vegetable with 1 serving per day, the risk of all-cause mortality (= death to all causes) significantly with 5% [95% CI = 0.92 to 0.99, p = 0.006] reduced.

The researchers found that increasing fruit with 1 serving per day, the risk of all-cause mortality (= death to all causes) significantly with 6% [95% CI = 0.90 to 0.98, p = 0.002] reduced.

The researchers found that the risk of not further reduced all-cause mortality above 5 portions of fruit and veg per day. The reduced risk was 26% [95% CI = 0.66 to 0.82] at 5 portions of fruit and veg per day.

The researchers found that increasing fruits and vegetables with 1 serving per day, the risk of dying from heart disease significantly with 4% [95% CI = 0.92 to 0.99] reduced.

The researchers found no link between eating lots of fruits and vegetables and reduced risk of dying from cancer.

The researchers concluded that eating 1-5 portions of fruit and veg per day the chance of death to all causes, especially from heart disease reduced.
