One More Note on Green Smoothies

Spinach is one of the yummiest greens to put in smoothies, so it's one of the best ones to use to introduce your family to green smoothies. but it does contain oxalic acid, which can inhibit some mineral absorption (calcium and iron). When we first started doing green smoothies every day, and we were only using spinach, I started to feel a little anemic. Then I learned about the oxalic acid and started using a wider range of greens, and I've felt much better. The Green Smoothie Girl says she has eaten handfuls of spinach every day for 15 years with no ill health effects, but she does recommend eating a wide range of greens.
