I’d like to begin by stating that this information is simply my opinion which is based on data I have read about natural health and from the 10+ years living and eating the way I have daily. That and my blood work results every 6 months which indicates no deficiencies, I think that this information is very valuable. Perhaps it just works for me, my genetics and body type, I can’t say for certain. But, just like cigarette smoke definitely will affect each one of us with varying degrees of health negatives, green smoothies, I believe, could probably have an affect on each one of us with various degrees of health positives. Try it for yourself, after speaking with your natural health practitioner.
