Wheatgrass is harvested early in its development before it reaches full size — usually 7-10 days after sprouting. Grown primarily to make hay, or for animals to graze, wheatgrass may also offer several health benefits.
Wheatgrass is sometimes called “green blood” because it contains high levels of chlorophyll that gives wheatgrass products an unusual green hue.
What is wheatgrass?
Wheatgrass has a number of health benefits and first became popular in the United States in the 1930s.
In the 1930s, agricultural chemist Charles F. Schnabel used young grasses to try to save dying chickens. The chickens survived and produced more eggs than other hens.
Quaker Oats and other companies began funding research into the benefits, and soon wheatgrass supplements, juices, and powders were widely available. Proponents of wheatgrass say that it is dense in plant nutrients that can improve health and offer supplemental nutrition.
When people consume the raw grass, they usually do so as part of a juice. Powdered wheatgrass is also available in capsules, liquid suspensions, or as a powder to add to smoothies.
Benefits of wheatgrass
Some of the benefits of wheatgrass include:
Antioxidant and anti-inflammatory
Wheatgrass can be used to help relieve stomach pain and improve symptoms of other gastrointestinal problems.
Antioxidants reverse the effects of free radicals. These volatile compounds in the body have links to aging and other health issues, including cancer. Antioxidants help fight chronic inflammation, which occurs when the immune system reacts to particular health issues, such as arthritis, stomach problems, skin issues. Antioxidants might even help with mental health concerns, such as depression.
Many health benefits of wheatgrass may be due to its role as an antioxidant. So it may offer benefits similar to many other plant-based foods.
Cancer prevention and treatment
Some research has found that wheatgrass can kill or slow the growth of certain infections. This can be especially helpful in the treatment of infections that are resistant to antibiotics, or in people who are allergic to specific antibiotics.
A 2015 study carried out in a test tube found that wheatgrass has antimicrobial properties that can fight certain types of strep infections, as well as some forms of a bacteria called Lactobacillus. Lactobacillus bacteria play a role in many infections, including dental infections.
Treating gastrointestinal distress
Practitioners of traditional medicine have long used wheatgrass to reduce stomach pain and manage minor gastrointestinal problems, such as diarrhea.
For people who do not see improvements using traditional medications, wheatgrass might be an alternative remedy.
Preventing and treating diabetes
Research has found that wheatgrass may benefit those with diabetes. A 2014 study on rats, for example, found that wheatgrass could raise insulin levels, helping to lower blood glucose. By fighting inflammation, wheatgrass may also help reduce the side effects of diabetes.
In addition to the health benefits, wheatgrass offers a number of nutrients that are essential as part of a balanced diet.
Though low in calories, wheatgrass is a good source of protein. It is not, however, a complete protein. Like most plant-based foods, wheatgrass is an excellent source of fiber, which can help reduce blood glucose. Wheatgrass can also support healthy digestion and help people feel full for longer than they usually would.
Wheatgrass is a good source of vitamins A, C, E, and K, and of vitamin B6, zinc, iron, selenium, and manganese.
People who are allergic to other grasses may also be allergic to wheatgrass. Likewise, due to cross-contamination and cross-pollination, it is possible for wheatgrass to contain the pollen of other plants.
People with plant allergies should consult a doctor before trying wheatgrass.
Some people experience nausea or constipation after consuming wheatgrass, perhaps due to its high fiber content. People with a history of constipation should talk to a doctor before trying wheatgrass.
Sometimes, the raw form of wheatgrass is contaminated by mold or bacteria. If preparing wheatgrass at home, wash it thoroughly to remove contaminants before using.
When consuming wheatgrass supplements, buy only from a trusted source. Consider contacting the manufacturer to ask what steps it takes to reduce the risk of contamination.
Wheatgrass taste and ideas for consumption
Wheatgrass tastes like grass, and it can overpower other flavors.
How to make it taste better
Mixing raw wheatgrass in a smoothie can still produce a drink that tastes like something out of a lawnmower. But combining wheatgrass with other ingredients that have a strong taste, such as pineapple or citrus fruit, can help balance the flavor.
Ways to consume wheatgrass
Including citrus fruit or pineapple in a wheatgrass drink can help to improve the taste.
Some people prefer to take powdered wheatgrass in capsule form. This almost eliminates the taste and can make it easier to get a daily dose of the grass.
A few wheatgrass supplement manufacturers offer flavored wheatgrass capsules or tablets that include citrus fruits or other dominant flavors.
For people who prefer not to experiment with smoothie or juice recipes, these may offer a tasty solution.
Many studies on the benefits of wheatgrass have produced promising results but have not been well designed. This means it is not possible to know for sure whether wheatgrass can treat or prevent any specific medical condition.
Because most people tolerate wheatgrass well, it is safe to use alongside other treatments. Nobody should take wheatgrass as a substitute for medical treatment. To test the benefits of wheatgrass, try a daily wheatgrass smoothie or supplement.
As research evolves, it may become clear that wheatgrass is an effective medical treatment for other medical conditions. For now, however, the research is inconclusive.
