NUTRIENT DENSE – The definition: Most commonly, nutrient density is defined as a ratio of nutrient content to the total energy content. Nutrient-dense food is opposite to energy-dense food (also called “empty calorie” food).
From the study: Powerhouse fruits and vegetables (PFV), foods most strongly associated with reduced chronic disease risk, are described as green leafy, yellow/orange, citrus, and cruciferous items, but a clear definition of PFV is lacking
Here is a cut out of the table:
By the way…. I’m glad that there is now a study that proves what I’ve always thought. Kale aint shhh when it goes up against the heavyweights.
And it doesn’t even taste good. Romaine lettuce is more nutrient dense. Popeye was right… all of our grandmothers were right. Spinach and greens. Get’em.
