Antioxidants act in conjunction. It has been tried to capture this phenomenon with so-called overall antioxidant status measurements like ORAC and TEAC. The apparent simplicity of measuring parameters like ORAC and TEAC has led to many flawed interpretations. There is however value in these parameters when applied in a thoughtful manner. It is illustrated that in vitro and in vivo comparison of fruits and products is possible with these parameters. They can also be used to discover new bioactive ingredients in tissue or in plants.
Oxidative stress is associated with many diseases, which are characterized by a chronic, often mild inflammatory response. Oxidative stress is connected to inflammation. Antioxidants frequently modulate this inflammatory process. Also in this respect, it has to be underlined that plant bioactive components all act differently in this oxidative/inflammatory stress. This obviously offers possibilities to adjust our diet further for optimal health.
