Trans fatty acids consumption in type 1 diabetic patients: evaluation by dietary records and measurement in serum phospholipids

The consumption of foods containing trans fatty acids (TFA), especially those produced by food industries, induces pleiotropic negative effects on health. Therefore, it is important to assess the amount of TFA consumed, especially in age groups more exposed to the consumption of TFA-containing foods. The present pilot study evaluates TFA intake in 54 young people with and without type 1 diabetes (29 young subjects with type 1 diabetes and 25 healthy subjects) through both dietary records (7-day food record) and the measurement of TFA levels in serum phospholipids, a possibly more objective marker of TFA intake. The comparison between the two groups was made by the student t test for independent samples. The intake of synthetic TFA was low in both groups (type 1 diabetic patients: 0.25 ± 0.25 g/day; healthy subjects 0.48 ± 0.37 g/day), but significantly lower in diabetic patients vs controls (P.05); TFA levels in serum phospholipids also confirmed a low intake of these fatty acids. These data indicate that the intake of trans fatty acids is relatively low in our population, i.e.,% of total calories in the diet, in line with what recommended by the World Health Organization.
