Health Effects of Oat and Oat Bioactive 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.

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

| Outcome Measure | Measure Description | Time Frame |
