Disclaimer: I hate kale.
That said, I have to admit that kale must be good for you since it’s a dark green veggie and dark green veggies are loaded with anti-oxidants.
In fact, according to a study in a journal called Frontiers in Aging Neuroscience (another disclaimer: until I came across this study, I’d never heard of this journal, which means absolutely nothing but then again . . . ), better brain health was linked with a higher level of lutein in study participants, all of whom were “middle-aged”. (And in this study, middle-aged meant anyone between the ages of 25 and 45, which is gonna shock the hell out of my thirty-something sons who still consider themselves young dudes).
Specifically, those study participants with higher levels of lutein in eye tissue scored better on cognitive testing for attention than participants with lower lutein levels (lutein is apparently easy to detect in the eye, and lutein eye levels correspond nicely with lutein blood levels).
And yes, lutein is found in higher amounts in kale and spinach, but also, thank god for my own eyes, in avocados and eggs, which are, to me at any rate, much nicer ways to get my hits of lutein than eating kale chips and kale salads.
