The term "superfood" is a marketing ploy, but that doesn't mean that foods with that label aren't beneficial to health when incorporated into a healthy diet. A big problem with how the public views these foods is that many seem to think that adding an extra avocado or goji berry to the Standard American Diet will make them immortal. And that's silly. You cannot judge the healthfulness or "superfoodiness" of a food item in isolation, but must consider the entirety of a person's diet as well as that person's overall health (e.g. age, weight, insulin sensitivity, etc...). However, if one were to adopt a diet based on whole foods (for lack of a better term) that includes many "superfoods" as keystones.... lots of leafy greens, berries, brassicas, avocados, garlic, pastured eggs, and small, oily fish along, etc, and lots of "superfood" fats like coconut oil, EVOO, and grassfed butter instead of canola, soybean, and corn oil... perhaps replacing sugary sodas and juices with coffee, green tea, and mineral water... that can make a huge difference. But that's a systemic change, not an incremental one. Eating one extra serving of superfood a day won't do much (anything?) for you if the rest of your diet is garbage.
