The DASH Diet: A measure of
compliance to a structured
remedy for lowering Blood
Pressure
DHBCI DIY Assignment
By: Jason Paulson
D.I.Y. Problem: I have uncontrolled hypertension.
Tried prescriptions in the past, though discontinued use
to try and treat with nutrition and exercise.
Unsuccessful, so it‟s time to try a structured, proven
approach for managing hypertension.
Purpose of the study: measure compliance to DASH
Diet, to help indicate
Insightful observations pertinent to my thesis are a plus too!
Theoretical Framework Cognitive Dissonance Theory- (Festinger „57)
Two dissonant cognitions:
1) I eat too many salt-laden foods, excess salt
increases blood pressure.
2) I have HTN, I don‟t want to take BP meds.
If Unaddressed, dissonant cognitions lead to “psychological discomfort”
e.g. ”I need to start eating higher proportion of whole foods, and less processed „relatively-healthy foods‟”.
How Do I Measure DASH
Compliance? I ascribed each of the eight DASH categories with a 5-point scale designating
specific values of servings for each group (based of a 3,100kcal/day diet).
For instance, „Grains‟ Grading criteria:
Grains- (minus two points if majority are refined)
5 pts. = 10-13 more servings
4 pts. = 8-9 servings or 14-15 servings
3 pts. = 6-7 servings or >15 servings
2 pts. = 4-5 servings
1 pt. = 2-3 serving
0 pts. = 0-1 servings

What I learned/
Insights Gained It‟s cheaper to follow DASH than my usual patterns
Just like the base of evidence suggests, DASH is
effective; I can manage my BP if I really apply!
Weak study design
I didn‟t factor caffeine into my scoring criteria
i.e. Confounder ignored
Disappointments with DASH There is no distinguishing between
meat, fish, poultry, nuts, and beans.
Only one serving recommended of nuts, seeds, and
legumes.
-This discourages eating a variety of foods from this
important food group.
