Genetic studies of oats reveal why grains are suitable for a gluten-free diet

Genetic research on oats at the University of Edithco One (ECU) shows why oats are the answer for most people with celiac disease and gluten intolerance.

“Oats have been found to be low in wheat gluten-corresponding protein and provoke an immune response from people with celiac disease.” ECU Professor Michel Kolgrave said on May 19.

Colgrave said Results of these surveys The team confirmed that “at both the genetic (DNA) and protein levels, oats have few protein sequences known to cause food allergies and intolerance,” and oats are gluten-based. We have confirmed that we share a more important genetic similarity with a rice plant. -Free, not wheat or rye. Both are rich in gluten.

Compared to other grains, oats also contain a much higher proportion Beta glucanLowers blood cholesterol levels and improves the immune system.

Associate Professor Jason Tye-Din said the study took a step further to reassure people with celiac disease about the safety of oats and allow grains to be included in gluten-free diets. ..

“Concerns that oats contain gluten-like proteins that can be harmful to people with celiac disease mean that oats are currently excluded from the gluten-free diet in Australia and New Zealand. “I will.”

People with a restricted gluten-free diet often have low intakes of whole grains. Often associated With diabetes and cardiovascular disease. However, the inclusion of oats can overcome many of these adverse effects.

New breeding possibilities

Oats aren’t just interesting because of their innate health benefits. Their cultivation also requires less treatment with pesticides, fungicides and fertilizers compared to other grains.

However, compared to wheat, oats are more difficult to mate with other grains that differ in the number of sets of chromosomes compared to them. It is also difficult for grains to take up foreign genes.

By genetic research, cultured oats (Avena Sativa) There are 6 sets of chromosomes (6n), 2 of which are Avena Longigur Miss (2n) and Avena insularis, There are 4 sets.

The authors speculated that A. sativa, which breeds from two species with different numbers of chromosome sets, could be a breeding barrier for oats.

However, researchers believe that this study will provide new insights into the genome and support the breeding and cultivation of more nutritious and sustainable oats.

“The freely available resources created in this collaboration are essentially oat blueprints, increasing the likelihood of reproduction targeting specific traits,” addressing the demand for plant-based proteins. High protein oats to do are listed as a possibility.

ECU Dr. Angéla Juhász said the findings could be of great benefit to the Australian oat industry.

“Research conducted by ECU and CSIRO has shown that not only proteins related to gluten-like properties of oats, but also properties that can increase crop yields, enhance nutritional profiles, and increase resistance to disease and drought. You can identify it, “she said.

“This will provide Australian producers with their own differentiated grain and maintain Australia’s position as a supplier of premium, high quality grain that brings certain health benefits to Australians. increase.”
