Effect of Organic Naked Oat With Whole Germ on Type 2 Diabetes Mellitus

December 15, 2011 updated by: Yong Li

Dietary modification is of great essential for the prevention and treatment of type 2 diabetes mellitus. Common oat (Avena sativa L.) and its products showed a great potential benefits on NCDs including type 2 diabetes mellitus. But data about such effects of naked oat (Avena nuda L.) is still unavailable. The investigators aimed to examine the effects of organic naked oat with whole germ (ONOG) plus diet on patients with type 2 diabetes.

After a pre-study with healthy adults, a randomized, single-blinded, multi-arm parallel trial of 30 days would be carried out in adults of 50-65 years old with type 2 diabetes. Participants would be randomly assigned to one of the four following groups: usual care group (only basic health advice, no other interventions), diet group (systematic education, structured dietary), 50g-ONOG plus diet group (all the interventions of diet group plus replacement of 50g ONOG per day) and 100g-ONOG plus diet group. A regular follow-up for years would be carried out to predict the long-term effects of ONOG plus diet intervention on patients with type 2 diabetes.

The investigators hypothesized that ONOG combined with diet would have better effects on glycaemia and insulin resistance control in addition to those yielded by diet or usual care.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Usual care group
The usual care group was used as control group and didn't receive any intervention except standard health advice at the beginning and the end of the study.
No Intervention: diet group
This group received systematic education about nutrition and diabetes combined with a structured dietary intervention.
Experimental: 50g-ONOG plus diet group
This group received systematic education about nutrition and diabetes combined with a structured dietary intervention. Participants in the 50g-ONOG plus diet groups were asked to replace their customarily used staple food with oat porridge containing 50g ONOG.
Dietary supplement: organic naked oat with whole germ (ONOG)
The experimental product was ONOG (Inner Mongolia Sanzhuliang Natural Oats Industry Corporation), which was produced in the northwest part of China, applying with the organic standards. Participants in the 50g and 100g-ONOG plus diet groups were asked to replace their customarily used staple food with oat porridge containing 50g or 100g ONOG.
