A new study titled "Comparison of the DASH diet and a higher-fat DASH diet on blood pressure and lipids and lipoproteins: a randomized controlled trial," has found that a proper DASH (Dietary Approaches to Stop Hypertension) diet greatly cuts down blood pressure, while also reducing low-density lipoprotein cholesterol (LDL-C) as well as high-density lipoprotein cholesterol.
This study is scheduled for publication in the American Journal of Clinical Nutrition and carried out by scientists from the UCSF Benioff’s Children’s Hospital Oakland Research Institute (CHORI). Just like the DASH diet, the researchers discovered that a higher fat DASH diet is capable of lowering blood pressure, and that is also lowers triglycerides without necessarily raising LDL-C.
A study initially funded by the National Institutes of Health formed the basis of this DASH diet, which has been found to possess several health benefits equal to the Healthy US Style Eating Pattern that also forms part of the three recommended dietary patterns of the 2015 Dietary Guidelines for Americans.
Led by Ronald Krauss and Sally Chiu as well as Nathalie Bergeron of CHORI, with Touro University, the researchers wanted to know if a good lipid and lipoprotein part of a DASH diet could sustain favorable blood pressure when modified with DASH diet that has full-fat dairy foods in it.
The researchers recruited a group of healthy individuals to consume a control diet, a standard DASH diet, and a higher fat but lower carbohydrate version of DASH diet for 3 weeks. The control diet has lower amounts of fiber, fruits, vegetables but more red meat than the other two diets. All the participants observed the diet assigned to them for 2 weeks before a washout period while they were asked to maintain a constant weight.

The participants numbered 36. The participants within the DASH and higher fat-lower carb category had lower blood pressure but not the control diet group. The higher fat-lower carb diet greatly lowered triglycerides, as well as low-density lipoprotein elements when compared with the DASH diet. Ultimately, the modified higher fat-lower carb diet is a more effective diet than the DASH diet which is largely recommended, and it has lesser dietary fat constraints that may enhance better implementation.
