The DASH diet has been rated the best diet for overall health and wellness for the past 5 years in a row.
Reduction of blood pressure. The DASH diet has been shown to reduce BP within 2 to 4 weeks (by 6 mmHg systolic and 3 mmHg diastolic). After this initial reduction the blood pressure is maintained rather than reduced further. Effects are more pronounced in people who are hypertensive rather than normotensive.
The DASH diet may further reduce cardiovascular disease (CVD) risk through reduction in total cholesterol, low density lipoproteins (LDLs) and body mass index (BMI).
Changes achieved with the DASH diet predict a reduction of CVD of approximately 13% using the 10-year Framingham risk score.
