Green leafy vegetables possess highest nutrition density and beans provide better nutritional value. However, it is now been revealed that potatoes are counted among one of the best with nutritional value.
The research was carried out by a group of researchers from the University of Washington. Lead researcher Dr. Adam Drewnowski said they prepared an affordable index by using the mix of nutrient profiling methods and national food prices data.
This prepared data was then used to examine the five vegetable subgroups, which included dark green vegetables, orange and red starchy vegetables, starchy, legumes and other vegetables.
After assessing them, it was found that dark green vegetables had the maximum nutrition density scores. But the starchy vegetables and beans were the ones, which provided better nutritional value for money.
"The ability to identify affordable, nutrient dense vegetables is important to families focused on stretching their food dollar as well as government policy makers looking to balance nutrition", said Drewnowski.
The study, funded by the United States Potato Board, has added to the growing evidence database that potato can be counted in healthy diet list. Potato has been found rich in potassium, fiber, magnesium and vitamin C.
