Backgrounds it has been shown that high levels of cholesterol and triglycerides besides low levels of HDL cholesterol are associated with higher risk of atherosclerosis and its consequences. The exaggerated elevation in triglycerides after a meal is an alteration that has raised concern in the last years. However, there isn't still a normality threshold for its behavior according to the findings in normal subjects Methods: We analyzed the variation in HDL cholesterol and triglycerides in a sample of 50 healthy individuals (25 men and 25 women), after intake of a test breakfast, regarding for the postprandial pattern for these parameters, specially the hour in which the maximum value of triglycerides was shown in the normal population and the value that could discriminate between healthy individuals and those with postprandial hiperlipemia. Results: We found a great variability in the postprandial behavior of triglycerides among individuals, specially in men. The greater percentage of individuals showed the maximum of triglycerides in the third postprandial hour. However the differences between men and women were not statistically significant The HDL cholesterol had only slight variations along the study, and they were not statistically significant. It wasn't possible to establish correlations among the HDL and triglyceride levels and the secondary measures relative to health condition, existing very low correlation levels. The trygliceride value in the second, third and fourth hour presented a high correlation. Conclusions: Our results show a similar behavior in postprandiallipemia in men and women. The greater elevation of triglyceride levels between second and fourth hour in 81,1 % of the patients allows us to suppose that a value obtained in this time interval is representative of postprandiallipids for an important part of the population. The behavior of HDL cholesterol seem not to show significative variations along the postprandial period, although it shows a small decline of 5% in the third hour, coincidentally with the greater elevation of triglycerides. If we want to use these findings to draw normal values that allow to discrimina te a normal pattern from a pathologic one, further studies will be needed gathering clearly iII populations and comparing their findings with those shown here.
