Study Description
Brief Summary:

This trial is being conducted to look for following changes when Korean traditional diets is taken in subjects with hypertension and type 2 diabetes:

To evaluate the improvement of the controlling fasting blood glucose and glycated hemoglobin.

To assess the controlling blood pressure and heart rate.

To evaluate the influence on cardiovascular risk factor, Triglyceride, cholesterol, High Density Lipoprotein-cholesterol and Low-Density Lipoprotein-cholesterol.

To evaluate the influence on Gamma-Glutamyl Transpeptidase.

To evaluate the influence on Cardiovascular risk factor.

To evaluate the influence on valsava score, breathing score and upright score.
