Obviously this isn't a scientific term, but "superfoods"have come to be known as foods that deliver an extra punch of nutrients. Most superfoods are fruits and vegetables, and while you might think of superfoods as something like acai berries or goji berries - something you probably can't find in your local supermarket - in fact, many superfoods are not exotic at all, and you can even grow them in your own garden!
In truth, homegrown foods are the most "super" foods of all when it comes to nutrients, as most fruits and vegetables begin to lose nutrients very quickly after harvesting. The closer you can consume your food to the time it was harvested, the more nutritious it will be. On the other hand, even the most nutrient-packed foods (like blueberries), become a lot less "super" after harvesting, shipping across the country, and sitting in the supermarket for several days.
It stands to reason that growing your own food is the best way to enjoy true superfoods in their healthiest form. And the good news is, it's actually not that hard to grow your own superfoods!
