The result was that lycopene could restraint of LDL oxidized violently, flavonoids and vitamin C were as also the effect. Oxidized-LDL was also subjected to electrophoresis, it was affirmed the extracts from these fruits and vegetables inhibited LDL to be oxidated and reduced Ox-LDL. It implies fruits and vegetables are be capable of prevention the cardiovasculard isease.
