Ancient Kernza Grain Offers Potential Benefits for digestive health and sustainable agricultural practices.
Kernza, a perennial wheatgrass grain, is making a comeback as a highly sustainable and nutritious crop. Originally known as Thinopyrum intermedium, this ancient grain has unique properties beneficial for both human health and the environment.
In the food industry, Kernza shows promise as a grain with high mineral nutrient density and protein concentration, making it valued for baking, brewing, and distilling applications. The brewing and distilling sectors are early adopters, with collaborations underway to explore Kernza’s properties for sustainable beer and spirits production.
One of Kernza's key advantages is its deep root system, which allows it to grow in marginal soils and reduce the pressure on more fertile agricultural land. This perennial grain is also drought-resistant, using water more efficiently than many traditional crops, thanks to its deep root system.
In terms of health benefits, Kernza's high fiber content promotes gut health, aids digestion, and supports a healthy microbiome. It also contains prebiotic fiber, particularly beta-glucans, which feed beneficial gut bacteria. Additionally, Kernza is rich in antioxidants, which help protect the body from oxidative stress and reduce inflammation.
Kernza's ability to improve soil health, sequester carbon, and conserve water makes it a key player in the transition to more sustainable farming practices. As a perennial crop, it reduces soil erosion and requires fewer inputs like fertilizer and water compared to annual grains. This aligns with broader carbon farming trends whereby perennial crops contribute significantly to long-term carbon storage in soil, thereby mitigating climate change impacts.
The Land Institute, an organization that has been researching Kernza for over 30 years, is working to improve the grain's yield and make it more viable for farmers around the world. Advancements in breeding have reduced seed shattering, enhanced grain size, and improved yield, making Kernza more commercially viable and adaptable to diverse climates.
Recent advancements in Kernza focus on its development as a sustainable crop with multifunctional uses in food and farming systems. A USDA-ARS interdisciplinary network is conducting large-scale, multi-location studies to understand Kernza’s agronomic performance, including yield variation, nutrient and water requirements, and environmental impacts, to optimize its integration into existing cropping systems across the U.S.
Research networks also integrate precision agricultural technologies for better nutrient and water management, enhancing Kernza’s efficiency in sustainable systems. These developments position Kernza as a promising perennial grain for a more sustainable and resilient food supply chain.
Kernza's main health benefits, coupled with its sustainability, make it a potential mainstream crop that supports healthy communities and a healthier planet. It offers a unique solution to some of the environmental problems associated with conventional agriculture, making it a key player in regenerative farming and climate resilience.
