What is a Powerhouse Vegetable?

What is a Powerhouse Vegetable?

Almost all nutrition advice recommends eating more  fruits and vegetables.

Nutrition experts recommend fruits and vegetables in the treatment  and prevention of several chronic diseases – diabetes, hypertension, high cholesterol, heart disease,  and cancers. The greatest health benefits have been attributed to the green leafy, yellow/orange, citrus and cruciferous varieties.

A 2014 research study tried to determine exactly which fruits and vegetables were most likely to keep us healthy.

They defined  “powerhouse fruits and vegetables” as those  highest in nutrients, specifically the minerals potassium, calcium, iron and zinc and vitamins A,B,C, D, E and K. They looked at the percent daily value  (DV) of these nutrients  per 100 grams ( 3.5 ounces) of each food.

The Food and Drug Administration defines foods providing 10% or more DV of a nutrient as good sources of the nutrient, or nutrient dense.

What were the results? 

Of 47 foods studied, all but 6 satisfied the powerhouse criterion .

from 100% to 70% nutrient dense

cruciferous -watercress, Chinese cabbage, collard green, kale, arugul

green leafy-(chard, beet green, spinach, chicory, leaf lettuce groups

from 62% to 24% nutrient dense

Other greens-collard, mustard, and turnip, kale, broccoli, pumpkin, and brussels sprouts

from 22% to 10% nutrient dense

Yellow/orange-carrot, tomato, winter squash, sweet potato, allium -scallion, leek,

citrus-lemon, orange, lime, grapefruit

berry- strawberry, blackberry groups

 

Raspberry, tangerine, cranberry, garlic, onion, and blueberry were all less than 10%.

So, besides the fact that fruits and vegetables taste good, here is another good reason to eat them.
