Kind of dietary pattern not only leads to nutritional deficiencies but also promotes a cluster of metabolic problems including obesity, reduced insulin sensitivity, glucose intolerance, dyslipidemia, as well as systematic inflammation-all risk factors for the most common age associated diseases that include cardiovascular diseases, particular cancers, type 2 diabetes, among others. As indicated above, dietary pattern analysis may represent a useful addition to the repertoire of researchers who study the relationship between diet and chronic disease. However, the reality, until very recently, has been that researchers have focused mainly upon the effects of individual nutrients and sometimes foods, but rarely on dietary patterns on disease risk factors, biomarkers, or morbidity.

The Dietary Approaches to Stop Hypertension (DASH) diet is, arguably, the most common physician prescribed diet to fight high blood pressure and was, in fact, originally developed by the National Heart, Lung, and Blood Institute to do just that, therefore, the acronym (Champagne 2006; Savika et al, 2010). The DASH dietary pattern is rich in fruits and vegetables, whole grains, low-fat dairy products, fish, poultry, beans, nuts and seeds. It also contains less sodium; sugar; fats; and red meat than the usual western diet as described above. Designed with cardiovascular health in mind, the DASH diet is also lower in saturated and trans fatty acids and cholesterol and rich in nutrients such as potassium, magnesium, calcium, protein, and fiber that are helpful for lowering blood pressure. Research on the DASH dietary pattern has shown that it not only can lower blood pressure but also improve other risk factors for cardiovascular disease such as HDL cholesterol levels, triglycerides or blood sugar.
