Electrolyte balances, blood pressure, and sugar preferences as affected by intakes of various sugars
Abstract
The overall objective of this project was to investigate the effect of consumption of various dietary sugars on electrolyte excretion, electrolyte balance, blood pressure, serum lipid level, and preference for sugar. For studies comprised the project. The first study consisted of feeding a controlled diet to two groups of 12 young adults. Subjects were fed a laboratory diet supplemented with sucrose, fructose, or high fructose corn syrup (HFCS). The test sugars fed at a level of 60 g/day did not significantly affect electrolyte excretion levels, serum lipid levels, or blood pressure. In Study II taste preference for sucrose in a lemonade solution and blood pressures were measured in hypertensive or normotensive elderly subjects. For the 39 subjects classified as normotensive sucrose preference tended to be positively correlated with systolic blood pressure, mean blood pressure, and weight. Hypertensive subjects exhibited an opposite trend in that sucrose preference was negatively correlated with mean blood pressure, body mass index, and weight. A consistent increase in sucrose preference with increasing age was not observed in this study. Differences in preferred sucrose solutions based on sex or race were not observed. In Study III, the relationship of sodium and potassium intake and urinary potassium and chloride excretion to mean blood pressure of elderly subjects consuming self-selected diets was studied. Hypertension was not associated with increased dietary intakes of potassium or sodium. Nor, was hypertension associated with altered urinary potassium or chloride excretion. Study IV was conducted at a workshop on home food preservation, stressing the reduction of salt and sugar in food preservation. The workshop was conducted for Extension Home Agents. Pre- and post-test evaluations indicated a significant increase in knowledge.
