LoriB.Wordpress.com has listed a number of superfood ingredients for morning smoothies.
Personally I try to incorporate:
Flax seeds for digestion
Yogurt for thryoid, protein, metabolism
Ginger, cayenne pepper and turmeric for inflammation
Spinach for iron and calcium
Blueberries for immune and skin
I use all these in my Superfood Blueberry Parfait, another great way to get these and more natural remedies into your diet!
