Levels of conjugated dienes of fatty acids (first
peroxidation product) in relation to their substrates and
promotors (triacylglycerols, homocysteine, iron) as well as
to their inhibitors (essential antioxidative vitamins) were
assessed in a vegetarian group (n=24) and compared with
subjects on a mixed diet (traditional nutrition, n=24).
Positive significant linear correlation between conjugated
dienes and triacylglycerols, homocysteine, iron as well as
inverse relationship between conjugated dienes and vitamin
E, vitamin C, beta-carotene were observed in pooled groups.
Lipid peroxidation risk in vegetarians seems to be caused
predominantly by hyperhomocysteinemia, whereas in a mixed
diet group this was due to a higher supply of substrates or
risk iron values. The incidence of only 8 % of risk
conjugated diene values in vegetarians in contrast to 42 %
in the group with traditional diet indicates that
vegetarians have a better antioxidative status as a
consequence of regular consumption of protective food.
