The superfoods you need for healthy living, and the six you don't!

Dietary experts and researchers from William Paterson University in New Jersey conducted a new study which compares the nutrient density of different fruits and vegetables and published their surprising results in the CDC journal Preventing Chronic Disease.

LOS ANGELES, CA (Catholic Online) - Almost 50 different fruits and vegetables were tested in order to find out how much of the 17 most important nutrients they contained. The fruits and vegetables were scored based upon how much of a person's daily nutrient value they contained, assumed as a 2,000 calorie per day diet with 100 grams of each food eaten in its raw state.

Thousands suffer from hunger every day, be the change that saves a life.

These nutrients included potassium, fiber, protein, calcium, iron, thiamin, riboflavin, niacin, foliate, zinc, and vitamins A, B6, B12, C, D, E and K.

Watercress revived the top score of 10, while broccoli got 34.89, kale 49.07 and tomatoes received a pitifully low score of 20.37.

The study showed that fruits are not necessarily as good for a person as vegetables because most fruits have only a few vitamins, as apposed to vegetables which contain multiples.

The scores were capped to ensure that no fruit or vegetable which contains a large amount of a single nutrient didn't receive a disproportionate amount of points.

Six fruits and vegetables that failed to perform well were raspberries, tangerines, cranberries, garlic, onions and blueberries, which lacked large amounts of nutrients in more than a single category.
