[Effect of low glycemic index diets in hyperlipidemia].
BACKGROUND
After consuming a low-glycemic-index (GI) diet, patients with diabetes and hyperlipidemia showed reduced biochemical markers of dyslipidemia. Despite Mexican food habits include low-GI foods; there have not been published results on the effect of low-GI diet on hyperlipidemia. The aim of this study was to compare the effects of a low and high glycemic index (GI), using cultural based foods to Mexicans on LDL, HDL, total cholesterol, and triacylglycerol.


METHODS
Eight volunter's individuals with hyperlipidemia participated in the study. Six diets were designed, three with low-GI and three with High-GI. The study design included 2 times 3-week treatment periods with a 4-week washout period between treatments. Biochemical data was obtained at the start and finish of each dietary period. Subjects completed 1-day dietary diaries during the first and third weeks of each of the treatment periods. Paired t-test was used to compare biochemical data at the baseline and after the dietary treatment periods.


RESULTS
At the end of the study periods, total cholesterol (P < 0.05) and LDL (< 0.02) were improved significantly by 10 and 13% respectively. A low GI diet containing Mexican foods during three week period may help to improve LDL and total cholesterol in individuals with hyperlipidemia.
