title: Selected parameters of lipid metabolism in young vegetarians.
abstract: Selected parameters of lipid metabolism (cholesterol, HDL cholesterol, LDL cholesterol, atherogenic index, triacylglycerols, vitamin C, vitamin E, vitamin E/cholesterol, plasma fatty acid profile) and pro-oxidative/anti-oxidative parameters (conjugated dienes of fatty acids, activity of catalase and glutathione peroxidase) were estimated in blood of 59 healthy vegetarians aged 19-30 years. When compared to non-vegetarians, no incidence of obesity, low levels of cholesterol, LDL cholesterol, atherogenic index or triacylglycerols, HDL cholesterol levels on the margin of 1.4 mmol/l (boundary level between standard and reduced risk) as well as a higher plasma content of polyunsaturated fatty acids and a higher 18:2/18:1 ratio were all favourable consequences of vegetarianism with respect to atherosclerosis prevention. These factors are completed by higher levels of protective compounds with antisclerotic activity (vitamin C, vitamin E/cholesterol--protecting LDL from lipoperoxidation) as well as by beneficial pro-oxidative/anti-oxidative parameters (low values of conjugated dienes, significantly higher activity of catalase, higher level of vitamin C).
