Study names top “powerhouse” fruits and veggies
The Centers for Disease Control has come out with a list of 41 “powerhouse fruits and vegetables,”based on the amounts of 17 critical nutrients they contain.
To create the list researchers at William Paterson University in New Jersey calculated how dense with nutrients various fruits and vegetables are, based on the percentage of the recommended daily intake for each nutrient the foods provide. Researchers then ranked the fruits and vegetables based on their content of fiber, potassium, protein, calcium, folate, vitamin B12, vitamin A, vitamin D and other nutrients that they consider important to public health.
At the top of the list was watercress, with a score of 100, which meant that the vegetable provides 100 percent of the daily need for each nutrient that the food provides. Number two was Chinese cabbage, with a score of 91.99, and third was chard, with a score of 89.27. Kale, the leafy green that has received a lot of attention in health media recently, was 15th on the list, with a score of 49.07. Fruits did not score high on the ranking—tomato had a score of 20.37, while strawberries received 17.59, and blackberries received 11.39.
The researchers said people should, however, make a point of consuming any of the fruits and vegetables that made the list.
