Daylong triglyceridaemia in healthy Mediterranean and northern European subjects.
BACKGROUND
A Mediterranean eating pattern and diet enriched in monounsaturated fatty acids may result in a favourable daylong lipid profile.


METHODS
19 Spanish males (aged 32 +/- 8 years) and 28 females (34 +/- 8 years) were matched to Dutch subjects on the basis of fasting capillary triglycerides (TGc), gender and age. TGc were self-measured at six fixed time points over three days. Daylong TGc profiles were calculated as areas under the curve (TGc-AUC).


RESULTS
Anthropometric parameters and fasting plasma lipids were comparable between Spanish participants and Dutch subjects. Insulin sensitivity (expressed as HOMA) was highest in the Dutch females (1.41 +/- 1.09 vs. 2.09 +/- 1.23 in the Spanish females, p < 0.05). Daylong TGc values were not different between Spanish and Dutch participants. Male Spanish subjects showed the largest daylong TGc increase after lunch, while in the Dutch males, the largest TGc increase was seen after dinner. Total daytime dietary energy and total fat intake were comparable when analysed by gender. However, the Spanish participants had a higher intake of monounsaturated and polyunsaturated fatty acids as percentage of energy.


CONCLUSIONS
There are no major differences in daylong triglyceridaemia between Dutch and Spanish subjects, despite different eating habits and a diet enriched in monounsaturated and polyunsaturated fat in the latter.
