I’ve been holding off on this for a year. My housemate happens to be an organic gardener and a nutrition expert. Last year he showed me a book with a zillion smoothie recipes. According to the book you can use various berry, fruit, and vegetable smoothies to improve a wide variety of health conditions.
I’ve done various fasts including a ten day water fast and a 28 day Master Cleanser fast. These all produced some great benefits.
