Measuring Daily Grain Intake Study

Measuring Daily Grain Intake Study

The primary objective of this study is to identify markers of daily whole grain oat and whole grain wheat intake in humans.

The aim of this study is to identify compounds that are found in blood and urine and are derived from repeated daily consumption of whole grain oat or whole grain wheat intake so that epidemiological studies can be conducted to provide more accurate associations between whole grain intake and health.
