Increasing incidence of hypertension and related cardiovascular disease, prompted the National Institute of health (NIH) to propose funding to determine the impact dietary patterns have on blood pressure in the (US National Heart, Lung, and Blood Institute, 2015). Working with five established medical research centers in different US cities, the Dietary Approach to Stop Hypertension (DASH) feeding trial was developed to investigate the effects of dietary patterns on blood pressure (Appel et al., 1997). The original study began in 1993, and completed in 1997. The study was novel in that it included a team comprised of nutritionists, nurses, doctors, and the research coordinators. The DASH diet was created to provide high levels of nutrients previously identified to help reduce blood pressure that had proven ineffective at reducing blood pressure in supplement form or individually (Appel et al., 1997). The DASH trial, was unique in that it was constructed to test dietary patterns and their effect on blood pressure, rather than looking at individual nutrients (Appel et al., 1997).
The study compared a "control diet" to two experimental diets:
• Control diet – A diet based on the typical American diet, high in meats and processed foods, limited fruits and vegetables, providing low levels of fiber, potassium, magnesium and calcium, and high levels of fat and protein.
• Fruits and vegetables diet – A diet higher in fruit and vegetables, otherwise similar to the typical…
