Like a large variety of grasses reared in the field such as oats, rye and barley, wheat grass belongs to the same group. It also refers to grass that is grown inside in special trays for around 10 days from which, later on, their juice is squeezed and consumed fresh. Grass that is dried and dehydrated for around sixty days is used to manufacture nutritional supplements. Such juice when mixed with some of the sprouted wheat berries is particularly rich in chlorophyll content. This juice is known to cleanse the body and to neutralize many of the toxins in our body along with slowing down the process of aging and at the same time is believed to help prevent cancer. A lot of people are aware of the benefits of these juices after seeing those TV adverts for the Jack Lalanne juicer machine which extol the virtue of fresh juices.
