Researchers Unveil the Health Benefits of Quinoa Sprouts
A new study conducted by researchers from Universidad Nacional de San Cristóbal de Huamanga and Universidad Nacional Mayor de San Marcos in Peru has highlighted the powerful antioxidant and gastroprotective effects of quinoa sprouts. The study analyzed three different quinoa varieties - Pasankalla, Yellow Maranganí, and Black Coito - focusing on their phytochemical composition and medicinal potential.
New Insights into the Antioxidant and Gastroprotective Benefits of Quinoa Sprouts
Understanding Quinoa Sprouts and Their Unique Properties
Quinoa, a superfood widely consumed in the Andean region, has gained global recognition for its exceptional nutritional content. The germination of quinoa seeds into sprouts enhances its bioavailability and digestibility, making it an even more potent source of health benefits. This
Medical News report delves into the recent findings that suggest quinoa sprouts may play a significant role in promoting gut health and preventing gastric ulcers.
Key Findings of the Study
-Phytochemical Composition and Antioxidant Activity
Using advanced techniques such as liquid chromatography-mass spectrometry (LC-MS), researchers identified a rich profile of bioactive compounds in quinoa sprouts, including amino acids, organic acids, monosaccharides, lipids, steroids, triterpene saponins, and coumarins. Notably, the Pasankalla variety exhibited the highest antioxidant capacity, with an impressive 36.70 µmol Trolox equivalent (TE)/mg for DPPH radical scavenging and 56.61 µmol TE/mg for ABTS radical scavenging. The Black Coito and Yellow Maranganí varieties also demonstrated strong antioxidant properties, although to a slightly lesser degree.
-Gastroprotective Effects in Preclinical Models
To evaluate the gastroprotective potential of quinoa sprouts, the study used a preclinical model in which gastric lesions were induced in male Holtzman rats. The results were striking:
-The anti-ulcer effect, measured by the percentage of ulcer inhibition, was 74.7% for Pasankalla, 69.5% for Black Coito, and 67.4% for Yellow Maranganí.
-The effectiveness of Pasankalla was higher than that of sucralfate (67.4%) and ranitidine (59.0%), two standard treatments for gastric ulcers.
-The pH of gastric contents significantly increased in rats treated with quinoa sprout extracts, indicating a potential role in acid suppression.
How Quinoa Sprouts Protect the Stomach
The protective effects of quinoa sprouts are believed to be attributed to their high concentration of amino acids and triterpene saponins. Amino acids such as leucine, valine, and tryptophan have been associated with mucosal healing, anti-inflammatory activity, and antioxidant defenses. Meanwhile, saponins help
by reinforcing the stomach lining, reducing inflammation, and inhibiting gastric acid secretion.
Implications for Human Health
While these findings are promising, further research is required to confirm whether similar effects occur in humans. Given the growing interest in natural alternatives for gut health, quinoa sprouts could be a valuable dietary addition for individuals seeking to prevent gastric ulcers or improve digestive health. Future studies should focus on human clinical trials and investigate the role of quinoa sprouts in treating ulcers induced by stress, NSAIDs, and Helicobacter pylori infections.
Conclusion
The study provides strong evidence that quinoa sprouts, particularly the Pasankalla variety, exhibit powerful antioxidant and gastroprotective properties. The presence of bioactive compounds such as amino acids and triterpene saponins plays a crucial role in reducing gastric ulcers and enhancing stomach health. These findings suggest that quinoa sprouts could be a potential natural remedy for individuals suffering from gastric issues, though further clinical studies are needed to validate these effects.
The study findings were published in the peer-reviewed journal: Scientia Pharmaceutica.
