A reduction in the amount of sodium added during food processing, as well as fast food and restaurant food preparation, has the potential to substantially reduce so- dium intake without the need for a conscious change in 4. Dietary potassium is inversely related to BP and hy- pertension in migrant studies,S6.2-88 cross-sectional and prospective cohort studies.S6.2-92 Likewise, dietary potassiumS6.2-93 S6.2-96 and a high in- take of fruits and vegetables are associated with a lower incidence of stroke.S6.2-97 Potassium interventions have been effective in lowering BP,S6.2-13,S6.2-14,S6.2-16,S6.2-81 especially in adult patients consuming an excess of and in blacks.S6.2-13 The typical BP-lowering effect of a 60-mmol (1380-mg) adminis- tration of potassium chloride has been about 2 mm Hg and 4 to 5 mm Hg in adults with normotension and hypertension, respectively, although the response is up to twice as much in persons consuming a high-sodium diet. A reduction in the sodium/potassium index may be more important than the corresponding changes in either electrolyte alone.S6.2-99 Some but not all studies suggest that the intervention effect may be restricted to adult patients with a low (1500-mg to 2000-mg) daily intake of potassium.S6.2-92,S6.2-100 Most of the intervention experience comes from trials of relatively short duration but the BP-lowering effect of potassium in adult patients consuming a high- sodium diet has been reproduced after an interval of 4.4 In most trials, potassium supplementation was achieved by administration of potassium chloride pills, but the BP response pattern was similar when di- etary modification was used.S6.2-13 Because potassium- rich diets tend to be heart healthy, they are preferred over use of pills for potassium supplementation.
