Wheatgrass was introduced to the world of health in 1940 by Charles F. Schnabel, an agricultural chemist. Since then, wheat grass has only continued to gain popularity due to claims of the young plant's detoxification and general nutrition value. Though not harmful, wheatgrass is best consumed in moderation.
Most wheat grass aficionados recommend incorporating wheatgrass into your diet slowly. Wheatgrass is sweet and full of vitamins, and it also acts as a natural laxative. That's a bad combination if you start off by drinking too much. A frequent complaint is nausea and diarrhea, sometimes accompanied by vomiting. One ounce a day is usually a safe amount to start with for the first week. After a week, you can begin drinking between 2 and 4 oz. a day, but spread it out throughout the day and be sure to drink wheatgrass between meals. Wheatgrass, which is the young form of the wheat plant, isn't digestible to humans unless juiced or made into a supplement. Wheatgrass needs to be consumed without food, and with a full glass of water. If you find the taste to be too sweet or strong, mixing it with another juice can take the edge off. Celery is a green vegetable whose taste melds well with wheatgrass. If you still struggle to drink wheatgrass juice, consider taking a daily supplement.
