And I wonder if the whole decrease in stroke is caused by the potassium in bananas? Potassium 21% Why eat three bananas a day?
Do the authors not know about bananas?
Fruits and vegetables consumption and risk of stroke
The authors conducted a meta–analysis to summarize evidence from
prospective cohort studies about the association of fruits and
vegetables consumption with the risk of stroke. Fruits and vegetables
consumption are inversely associated with the risk of stroke.
Methods
- Pertinent studies were identified by a search of Embase and PubMed databases to January 2014.
- Study–specific relative risks with 95% confidence intervals were pooled using a random–effects model.
- Dose–response relationship was assessed by restricted cubic spline.
- Twenty prospective cohort studies were included, involving 16 981 stroke events among 760629 participants.
- The multivariable relative risk (95% confidence intervals) of stroke for the highest versus lowest category of total fruits and vegetables consumption was 0.79 (0.75–0.84), and the effect was 0.77 (0.71–0.84) for fruits consumption and 0.86 (0.79–0.93) for vegetables consumption.
- Subgroup and meta–regression showed that the inverse association of total fruits and vegetables consumption with the risk of stroke was consistent in subgroup analysis.
- Citrus fruits, apples/pears, and leafy vegetables might contribute to the protection.
- The linear dose–response relationship showed that the risk of stroke decreased by 32% (0.68 [0.56–0.82]) and 11% (0.89 [0.81–0.98]) for every 200 g per day increment in fruits consumption (P for nonlinearity=0.77) and vegetables consumption (P for nonlinearity=0.62), respectively.
