While most of us can agree that the idea of a “superfood” is supposed to be something that is good for our health, you might be surprised to find out there’s no real consensus about what defines a super food.
Superfood is a term that gets thrown around a lot. Sometimes it pertains to berries, other times you see it ascribed to grains or seeds, and there’s no shortage of packaged and processed snack foods that are touting the superfood label.
But a unique study by researchers at the Centers for Disease Control and Prevention (CDC) and published in the journal Preventing Chronic Disease sought to define what really is a superfood.
Now, these researchers steered clear of the somewhat controversial term “superfood” and decided instead to call their subject matters “powerhouse fruits and vegetables”. And what they did was to study the relative nutrient density of 47 different pieces of produce to analyze which ones were PFVs (powerhouse fruits and vegetables).
To qualify as a PFV, a fruit or vegetable had to have 10% or more daily value per 100 calories of 17 different qualifying nutrients. Based on the nutrient analysis, here are the top 10 “powerhouse fruits and vegetables”, ranked in order from highest nutrient density score:
- Chinese cabbage
- Beet green
- Leaf lettuce
- Romaine lettuce
- Collard greens
You might have noticed a pattern here – that these are mostly dark green leafy vegetables. If you’re looking for an area where you can make an improvement in the nutrient density of your diet, try adding more greens to your meals. You can do so in salads, stews, sautéed or even ground up and mixed into patties to help cut meat when you’re enjoying burgers or meatloaf.
