Our approach to nutrition is typically rooted in the question, "What am I missing?". What is the magical ingredient? This mentality drives the constant search for superfoods. The term is alluring. We all want to be superheroes... so give us the superfoods. I remember back when I got serious about fitness. I'd see the lists - salmon, blueberries, kale - and try to jam as many of them into my diet as possible.
By and large, the issue for most people is not one of deficiency... it is one of excess. After a decade of experience trying every diet under the sun, it's clear to me that there are no superfoods. All foods are super if they are whole and unprocessed. Why? Because a whole food diet is the most sustainable way to achieve energy balance... and energy balance is the most important aspect of nutrition. Simply put, when we eat whole foods we tend not to overeat.
Eating whole foods isn't sexy, and there isn't any way for the corporations to make money on it, so you will continue to get marketed all kinds of crap. Don't buy it. Just buy whole foods and make time to cook. That's the recipe to be a superhero.
