The idea behind that phrase is not that is necessarily easy... but to decomplicate the other extreme where you are choosing this superfood and avoiding that other veg because it is "bad for you". It gives a simple heuristic for healthy living. It helps make it less daunting.
For example what do I have for breakfast? Oh let's boil and egg amd grab a carrot and corn on the cob. Or whatever.
What do I do in the supermarket? Meats, veg, bit of fruit maybe bit of dairy. Am I obessing over avacado vs. pear. Nope. Chicken vs. beef? No. Chocolate bar vs carrot? easy choice.
Now probably once you get thay square you can do harder stuff like food reaction / allergy testing and so on.
