Don't know about the sardine smoothie!!!hmmm... a green tea, blueberry, carrot, almond, pomegranate, and salmon smoothie! DELICIOUS!
Actually, a co-worker just told me yesterday that a homeopathic doctor in california told her to eat sardines to improve her skin and to help her to lose weight. That was two years ago. I do admit she has been looking great. She has lost a noticeable amount of weight and looks younger than she did 8 years ago when I met her.
Should sardines be added to the smoothie too?
