Abstract
|
|
|
Korean style DASH (Dietary Approaches to Stop Hypertension) and a dietary education program for sodium reduction
were developed. Reduced sodium diets (15 and 30% reductions) were developed from general diets for 3 consecutive
weeks from Monday through Saturday. Subjects (19 total) were classified into two groups according to dietary education.
Experimental period was from June 24 to July 23, 2012. Total sum of adaptation scores for low sodium diets significantly
increased in the group that underwent dietary education compared to that without (p<0.05). After the experiment, both
groups showed significantly increased values in terms of food group balance, sodium-related nutrition knowledge, attitude,
and practice by paired t-test. Especially, group that underwent dietary education showed significantly higher values for
attitudes by ANCOVA pre-test as a variation (p<0.01). For the results of the nutrient intake survey, group that underwent
dietary education showed significantly increased values for dietary fiber (p<0.01), vitamin A (p<0.001), vitamin K
(p<0.001), vitamin C (p<0.01), Folic acid (p<0.001), vitamin B12 (p<0.01), calcium (p<0.01), iron (p<0.05), and zinc
(p<0.05) and significantly decreased values for sodium (p<0.05) and chloride (p<0.005). Subjects adapted to reduced
sodium diets showed apparent improvements in sodium-related knowledge, attitude, practice and intake of nutrient, and
these improvements were even higher in the group that underwent dietary education compared to that without. Thus,
adaptation to low sodium diet combined with dietary education can improve dietary habits.
