Health Benefits of Conventional, Organic and No-till Whole Wheat

CSANR Project 089

Status: Complete

Project Summary

There is growing consumer demand for foods perceived as being safe, healthy and sustainable. Organic and no-till wheat are often perceived as safe and sustainable and are well-positioned to gain market share if nutritional or quality advantages can be identified. Considering the known effects of environmental conditions on grain yield and quality, we hypothesized that no-till and organic cropping systems alter the mineral content, dietary fiber, total antioxidants, phenolics, and glycemic index of wheat grain. Organic wheat has been obtained from replicated field studies in Pullman, WA and Bozeman, MT, whereas no-till wheat was obtained from long-term replicated field studies in Oregon. We have expanded our project in two respects not included in the original proposal: (1) we are evaluating organic soft white winter wheat, in addition to organic hard red spring wheat, and (2) we are evaluating quality characteristics of no-till wheat, in addition to the nutritional characteristics. The results for end-use quality comparisons between organic and conventional wheat are discussed in our previous BIOAg report on “Wheat Quality in Organic and Conventional Dryland Cropping Systems”.

Additional Funds Leveraged

Shepherd’s Grain provided $6,000 in 2010 to support this project, and agreed to provide a second year’s funding in 2011 as well. Once we’ve established this two-year evaluation and proven ourselves as capable of evaluating the role of cropping systems on nutritional value, we would be able to develop other proposals, such as AFRI and the OREI (Organic Research and Extension Initiative) project (Burke, Fuerst et al.). Our OREI proposal is a “long-term project” and as such is intended for a renewal. Any such information we can gather will help us when we are due for that renewal.
