Introduction: in the last few years, as the rate of childhood obesity has been rising, there has been a parallel increase in the incidence of dislipemia in the pediatric population, in which blood triglycerids might play an important role. Plant sterols have been shown to be useful in the tratment of hypercholesterolemia, but not of hypertrygliceridemia. Our study focusses on determining the efficacy of phytosterol-supplemented milk for the treatment of hypertriglyceridemia in children. Study Population and Method: we designed a double- blind, randomized, controlled clinical trial on 67 pediatric patients. The treatment group received low-fat, phytosterol-supplemented milk and the control group received low-fat conventional milk., Results: we observed differences in triglyceridemia between the phytosterol-supplemented group and the non-supplemented group. The effect attributable to the intake of milk supplemented with plant sterols was a reduction of triglyceridemia of 5.88 mg/dl compared with the control group., Conclusion: we conclude that phytosterol-supplemented milk (2.24 gr of plant sterols daily) might be an adequate tool in the management of hypertriglyceridemia in pediatric patients., (Copyright AULA MEDICA EDICIONES 2014.

Background and Objective: Metabolic syndrome (MS) frequency is growing and diet has an important influence on its evolution. Our objective was to study the effect of 3 sources of polyunsaturated fatty acids on MS parameters in humans., Patients and Method: The MS was diagnosed according to the International Diabetes Federation. Three groups of individuals (n=15/group) were quasi-randomly assigned to one of the following treatments during 6 weeks: a) 1.8 g/d n-3 (1.08g eicosapentoaenoic acid+0.72 g docosahexaenoic acid); b) 2.0 g/d conjugated linoleic acid (CLA, 50:50, cis9:trans11, trans10:cis12), and c) 40 g/d walnut. The clinical and biochemical parameters were evaluated at the beginning and the end of the essay., Results: In the group with n-3 the triglycerides level decreased from 183.9 ± 35.2mg/dl to 149.6 ± 29.0mg/dl (P=.007). In the group with walnut the HDL level rose from 41.7 ± 5.2mg/dl to 47.8 ± 5.4 mg/dl (P=.004) and the Castelli index (total cholesterol/HDL) decreased from 4.86 ± 0.97 to 3.82 ± 0.81 (P=.004). There were not significant changes in the CLA group. At the end of the essay, 46.7% of walnut group patients, 46.7% of n-3 group and 20% of CLA group, had no MS., Conclusions: The groups that consumed polyunsaturated fatty acids n-3 and those in walnut in moderate daily doses during 6 weeks had an improvement of the dyslipidemia component of MS, hypertriglyceridemia and low HDL level., (Copyright © 2011 Elsevier España, S.L.
