Actually I have been regularly eating most of the foods on the NYT's list for some time now. This is my list of "super foods" culled from various sources. When my youngest left the nest, I wanted to simplify my life, and with this list I don't have to plan meals and make elaborate shopping lists like I used to. If I have most f these on hand, I can whip up something tasty in 15 minutes.
As for frozen (blueberries), they are a good substitute for fresh for the months when fresh are out of season, you just toss a handful in fruit salad/smoothie/yogurt every day.
Broccoli (chard, collard,kale, turnip tops, beet tops)
Papaya, pineapple, kiwi
Wild salmon (tuna, mackerel, blue fish, sardines)
Acai, gogi berries, cranberries
Prunes, other dried fruits
Dark red grapes
The article is right on track. Like so much reporting that we endure today, it is a mere soundbite/picturebite/convenient approach to a much larger issue. But, if it serves to lead even a few folks away from the Kraft Blue Box and towards the full nutritional bounty of better choices in the plant and animal kingdom, then job well done.
Here's a link to a place to get a fuller handle on the healthiest/superfoods issue, with prep ideas for each item:
