(AMSTERDAM) -- An apple a day could do more than just keep the doctor away. Dutch researches have found that eating many fruits and vegetables with white flesh, such as apples and pears, may protect against stroke.
While past studies have linked high consumption of fruits and vegetables with lower stroke risk, this Dutch Morgen study is the first to examine a color based correlation.
The color of the edible portion of fruits and vegetables indicate the presence of certain beneficial chemicals found in plants, such as carotenoids and flavonoids.
These findings seem to counter the popular belief that the most healthy fruits and vegetables are actually those that are rich in color inside and out.
The researchers tracked fruit and vegetable intake based on the color of the largest edible portion of food: green, orange/yellow, red/purple and white. After analyzing data collected from 20,069 individuals ages 20-65 during a 10 year period, the investigator documented 233 strokes among the participants.
They found that although there was no relationship between stroke risk and brightly colored fruits and veggies, people who consumed more white produce daily, had a 52 percent lower risk of stroke than those who ate less than the equivalent of an apple a day. On average, every 25 grams of white fruit eaten daily was directly associated with a 9 percent lower stroke risk.
One of the weaknesses of the study, however, is that the documented eating habits were based off of individuals' own recollections of consumption, so the data may be questionable.
