Wheatgrass is allowed to grow longer than malt. Like most plants, it contains chlorophyll, amino acids, minerals, vitamins, and enzymes. Claims about the health benefits of wheatgrass range from providing supplemental nutrition to having unique curative properties, though few, if any, have been scientifically proven.
Wheatgrass is often used for juicing, or added to smoothies or tea. Proponents say that wheatgrass has numerous health benefits, but there are no significant research studies to support these claims. Wheatgrass is usually grown in soil or water and consumed raw, which means it could be contaminated with bacteria or mold.
