Corn is not one of the most nutrient-dense foods, but you can make some choices that will up the ante. 1) Buy organic. Conventionally, this crop is heavily sprayed with pesticides. 2) Buy it in season for best flavor. After a few hours of picking the sugars are already turning to starch. Shipping takes days. 3) Steam it; boiling will cause most nutrients to leach into the water. 4) Frozen organic corn has pretty much the same nutrient profile as fresh, since its frozen at the top of it’s game. 5) When available buy colored corn. More colors = more healthy phytonutrients.
