It is now available in convenient single serving sachets, so that you may carry your wheatgrass with you. All you need is a glass of water, mix in the sachet of Wheatgrass Powder, and you have a drink that is better tasting than fresh juiced, and has more nutrition because it has combined the roots and blades. You don't have to invest in an expensive wheatgrass juicer, or try growing your own wheatgrass (not an easy task), or go to the local "juice bar" for a $3.00 shot.
The science behind the green drinks lies in the fact that they contain a lot of chlorophyll. In a plant, chlorophyll is transformed into Adenosine Triphosphate or ATP. If you have had cellular biology, then you know that this is the molecule in the body that is responsible for storing your energy. Chlorophyll is also what gives plants their green color. So, when you drink the greens in liquid form, you're actually eating the energy that has been produced by the sunlight - it's all natural!
Some foods don't juice well and should be avoided. For example, foods such as bananas, dates, and strawberries don't contain much juice. I don't recommend juicing rhubarb or buckwheat green sprouts, they contain some toxins that are concentrated in the juices.
It is easy to grow: You can easily grow it yourself at home. Youn can grow the plant within a week and it's ready for consumption! In fact, this is its optimum growing time. You will need to buy an electronic or manual wheatgrass juicer in order to extract the juice (a normal juicer is not suitable).
It's best to freeze the fruit/s you use beforehand, so your smoothie stays colder and thicker. Fresh fruits give a thinner, juice-like consistency to your smoothies, so if you like them that way, then don't bother freezing your fruit. Before freezing your bananas or melon, chop them into pieces and spread these on a plate so they won't freeze into one big lump.
These are but a few snippets of information and never meant to be an in depth analysis of the literature but merely a pointer to the beneficial effects of using wheatgrass either as check here a juice or in powder form.
