Abstract
Reduction in the mean glycemic index (GI) of diets of 12 hyperlipidemic patients from 82 ± 1 to 69 ± 2 units (p < 0.001) for a 1 mo period resulted in a significant reduction in total and LDL serum cholesterol and serum triglyceride by comparison with the mean lipid values for the preceding and following control months. The change in GI of the diet was achieved largely through manipulation of the cereal products and was not related to large differences in the amount of dietary fiber. In addition, apart from a small mean increase in unsaturated fat and calorie intake during the control periods, no difference was seen between the proportion of macronutrients on either treatment as determined by 1 wk diet histories recorded on alternate weeks throughout the 3 mo study. Selection of low glycemic index foods may therefore be a useful adjunct to the management of hyperlipidemia.
