  6. Grapes

  7. Spinach

  8. Cucumbers

Other organic rules of thumb

Eating the skin rule. If you plan on eating the skin of the fruit or vegetable, the general rule is that you should buy organic. If you don't plan on eating the skin then non-organic/conventionally grown can be ok.

Larger is not always better rule. A large or shiny fruit is not necessarily a sign of Nutrient Density. It could be a sign that the produce has taken on more water due to being a GMO (Genetically Modified Organism) or having been grown using an artificial fertilizer.
