A recent study from the Salt Institute Cellular Neurobiology Laboratory found that fisetin, a naturally-occurring flavonoid found most abundantly in strawberries, and to a lesser extent in other fruits and vegetables, can reduce the complications of diabetes. It may also reduce inflammation that is thought to promote some cancers.
To reach the protective effect, a person would need to eat 37 strawberries a day. In practice this is not a realistic recommendation. But, this study, like many others, does reinforce the recommendation to include ample fruits and vegetables in our diets daily to promote health and prevent illness.
