Health Effects of Oat Bioactives (Betaglucan) in Human

Study Overview
=================
Brief Summary
-----------------
Aim of the study is to investigate health effects of oats and oat derived components, in human intervention studies, with the purpose to build new knowledge for development of cardiometabolic protective foods.

Detailed Description
-----------------
The overall goal is to increase the knowledge which can be used for the development of food products with anti-diabetic properties, with the purpose to facilitate healthier food choices for people. More specifically the primary purpose of this project is to evaluate effects in healthy humans on cardiometabolic test markers of oat and oat based product. The new knowledge will form a base for the development of oat based food products with added health values.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Oat meal 1<br>The test portion is based on 30 gram available carbohydrates with added x amount oat betaglucan. Test portion consumed as a breakfast meal prior to determinations of test variables in the morning | Dietary Supplement: Effects of Oat and Oat Components on Cardiometabolic risk variables<br>* Oat and oat bioactive components consumed as breakfast meal.<br>|
| Experimental: Oat meal 2<br>The test portion is based on 30 gram available carbohydrates with added y amount of oat betaglucan. Test portion consumed as a breakfast meal prior to determinations of test variables in the morning | Dietary Supplement: Effects of Oat and Oat Components on Cardiometabolic risk variables<br>* Oat and oat bioactive components consumed as breakfast meal.<br>|
| Experimental: Oat meal 3<br>The test portion is based on 30 gram available carbohydrates with added z amount of oat betaglucan. Test portion consumed as a breakfast meal prior to determinations of test variables in the morning | Dietary Supplement: Effects of Oat and Oat Components on Cardiometabolic risk variables<br>* Oat and oat bioactive components consumed as breakfast meal.<br>|
| Placebo Comparator: Reference<br>The test portion is based on 30 gram available carbohydrates without added oat betaglucan. Test portion consumed as a breakfast meal prior to determinations of test variables in the morning | Dietary Supplement: Effects of Oat and Oat Components on Cardiometabolic risk variables<br>* Oat and oat bioactive components consumed as breakfast meal.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Blood glucose regulation | Postprandial blood glucose regulation (incremental area under the curve) acute after intake of the test products and at forthcoming meals within 5.5 hours after consumption of test products. | Time Frame: 0 - 5.5 hours ( at fasting and then repeatedly after breakfast and Standardize lunch) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Serum insulin | Acute effects of postprandial serum insulin concentrations (incremental area under the curve) after intake of the test products. | Time Frame: 0 - 5.5 hours ( at fasting and then repeatedly after breakfast and Standardize lunch) |
