Wheatgrass — Frequently Asked Questions

Wheatgrass harvested before the jointing stage (when the grass is young and has not produced seeds) should not contain gluten proteins, which are found in the wheat kernel. However, commercial wheatgrass products may be cross-contaminated during harvesting or processing. If you have celiac disease or severe gluten sensitivity, only use products that are certified gluten-free and tested for gluten content.

Most detox claims for wheatgrass are not supported by rigorous clinical evidence. While wheatgrass contains chlorophyll and antioxidants that support the body's natural detoxification pathways (particularly liver phase II enzymes), there are no well-designed human trials demonstrating that wheatgrass 'detoxifies' the body in any meaningful clinical sense. The antioxidant benefits are real, but the detox marketing overstates the evidence.

There is insufficient clinical data on wheatgrass safety during pregnancy. While it is a nutrient-rich whole food, concerns include potential mold contamination in fresh preparations and lack of standardization in commercial products. Pregnant women should consult their healthcare provider before using wheatgrass and, if approved, use only reputable, third-party tested products.

One well-designed double-blind RCT by Ben-Arye et al. (2002) found that 100ml daily wheatgrass juice significantly reduced rectal bleeding severity and overall disease activity in patients with active distal ulcerative colitis over one month. While promising, this is a single small study (23 patients) and should not replace standard IBD treatment. It may be considered as a complementary approach with your gastroenterologist's approval.
