Various methods have been developed to measure total antioxidant capacity or
activity, such as the ORAC (43), or the 2,2-diphenyl-1-picrylhydrazyl (DPPH?
) (113)free radical assay which measures the antiradical power (ARP): the higher the
ARP, the more efficient the antioxidant. In general, more than 80 % of the total
antioxidant capacity in fruits and vegetables comes from ingredients other than vitamin
C, indicating the presence of other potentially important antioxidants in these
foods (43). ORAC varies considerably (20-30 fold) from one kind of fruit or vegetable
to another. As expected, the majority of studies have been carried out in cultivated
fruits and vegetables. Brussel sprouts are one of the vegetables that show high ORAC
activity. Garlic, kale, and spinach are particularly high, as are strawberries and
plums.
In a recent paper on the systematic screening of total antioxidants in dietary
plants, using the ferric-reducing ability of plasma (FRAP) method (43), Halvorsen et al.
(114) emphasized the need for a systematic analysis in order to facilitate research into the
nutritional role of a combined effect of antioxidants in dietary plants.
CONCLUSIONS
Current research clearly shows that human beings evolved on a diet that was based on
wild plants, particularly green leafy vegetables, meat from animals in the wild,
and fish from rivers, lakes and deep cold sea water. This diet provided equal amounts
of omega-6 and omega-3 essential fatty acids. Furthermore, the diet contained
omega-3 fatty acids from terrestrial sources (predominately ALA) and high amounts of
EPA and DHA from both animals and fish.The green leafy vegetables provided
antioxidant vitamins, minerals, and various phytochemicals with antioxidant properties.
Studies on wild plants relative to the omega-3 fatty acids and antioxidant content
are being carried out in various parts of the world. As expected, they show enormous
variation in the content of both omega-3 fatty acids and antioxidants due to variation
in climatic conditions and cultivars. In developing new sources of food, the study of
the dietary composition of wild plants is essential. Their cultivation should lead to
increased production of plants rich in omega-3 fatty acids and antioxidants, both of
which reduce the risk of chronic diseases.
