Kale not worth the “nutritional” hype?

Do you know what a powerhouse fruit or vegetable (PFV) is? The exact definition is, as Dr. Jennifer Di Noia says, “lacking.

Powerhouse Fruits and Vegetables

According to the Centers for Disease Control Prevention, PFVs are fruits and vegetables with nutrients that can reduce the risk of chronic diseases, but gives no other guidelines.

Dr. Noia and colleagues have now determined guidelines for PFVs thanks to their study. In essence, they wanted to see which foods pack the most nutrition.

To define what a powerhouse food is, they developed and  validated a classification system. The system says, on average, that the food must contain 10% of 17 nutrients in 100 calories.

They studied 47 foods, and 41 qualified as a PFV. You’ll be surprised what topped the list as the most nutrient dense food. It’s watercress, a leafy, green vegetable.

Watercress is the new Kale

I would have thought Kale would be number 1. It’s up there, but it doesn’t even rank in the top ten of the 47 foods tested!

I’m about to go look up some recipes for watercress now. Who knew?!

Let’s get energized! 🙂

    • Kale is still delicious and good for you. I know a lot of people who think it’s THE best food source though, so I found the study interesting.

      I’ve been wanting to try kale chips. This is the perfect reason to actually do it! Thank you 🙂
