I found out that wheatgrass is a type of plant, which looks a lot like the kind of grass you grow on your lawn (although it is actually a young gluten-free form of wheat). There are many, often extreme claims about the health benefits of wheatgrass of which various critics are skeptical. The supporters of wheatgrass claim that it has extremely high amino acid, vitamin, mineral and chrolophyll content. The supposed benefits are that it helps prevent diabetes, heart disease, hair loss and cancer while promoting a general feeling of well being by promoting better blood flow and detoxification.
As you probably would suspect, wheatgrass tastes like grass! If you want to try drinking some, and you don't like the taste of grass, then you should probably consider adding it to fruit juice or to a smoothie. I bought some frozen "ice cube" like trays (2.5 calories each) of wheatgrass juice from Whole Foods, made by a company called Evergreen, that are fun to pop in my mouth during times when I am feeling hungry (the grass taste calms my hunger). I'm sure I could achieve a similar effect with frozen juice, but when I eat wheatgrass I feel like I'm doing something good for my body, since wheatgrass juice is probably at least as good for me as eating any other green vegetable, if not better!
