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.

Arm	Интервенция / лечение
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.
Experimental: 100g-ONOG plus diet group This group received systematic education about nutrition and diabetes combined with a structured dietary intervention. Participants in the 100g-ONOG plus diet groups were asked to replace their customarily used staple food with oat porridge containing 100g ONOG.

1. change from baseline in Hb1Ac concentration Hematology index detection Hematology index detection Hematology index detection Hematology index detection Hematology index detection [baseline, 30 days, 6 months and 1 year]

Venous blood samples were collected for determination of glycosylated haemoglobin (HbA1c).Changes in outcomes were calculated as values at the end of the intervention period minus those of baseline.

2. changes from baseline in insulin resistance Hematology index detection Hematology index detection Hematology index detection Hematology index detection Hematology index detection [baseline, 30 days, 6 months and 1 year]

Venous blood samples were collected for determination of serum insulin.Insulin resistance was measured by HOMO-IR, calculated with the following formula: HOMO-IR=Fasting serum insulin(μU/mL)*FPG(mmol/L)/22.5

Вторични изходни мерки

1. changs from baseline in plasma glucose [baseline, 30 days, 6 months and 1 year]

Venous blood samples were collected for determination of fasting plasma glucose(FPG), postprandial blood glucose (PG).Changes in outcomes were calculated as values at the end of the intervention period minus those of baseline.

2. changes from baseline in lipid profile [baseline, 30 days, 6 months and 1 year]

Venous blood samples were collected for determination of total triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c). Changes in outcomes were calculated as values at the end of the intervention period minus those of baseline.

3. changes from baseline in BMI [baseline, 30 days, 6 months and 1 year]

Weight and height were measured at each time. BMI was calculated as weight divided by square height.Changes in outcomes were calculated as values at the end of the intervention period minus those of baseline.

4. changes from baseline in plasma levels of total glutathione peroxidase, malondialdehyde(MDA), superoxide dismutase (SOD), IL-6 and TNF-а [baseline and 30 days]

Venous blood samples were collected for determination of total glutathione peroxidase, malondialdehyde(MDA), superoxide dismutase (SOD), IL-6 and TNF-а. Changes in outcomes were calculated as values at the end of the intervention period minus those of baseline.

5. changes from baseline in WHR [baseline, 30 days, 6 months and 1 year]

waist circumference and hip circumference were measured at each time. WHR was calculated as waist circumference divided by hip circumference.Changes in outcomes were calculated as values at the end of the intervention period minus those of baseline.
