Fruitless Green Smoothies

FYI: A number of the "vegetables" you list as ingredients for your fruitless smoothies are actually fruits. Not all fruits are sweet, but they have seeds with the potential to grow into a new plant - avocados, cucumbers, tomato, lemon, persimmon, quince, pepper, chile.

In contrast, rhubarb, often used in pies and jellies, is a vegetable. Does your friend's doctor mean no fruit or no sweet/high-sugar produce? I am concerned if it is a nutrient, other than sugar, in the fruit of plants that will contribute to cancer.
