Research suggests that the possibility of human plasma
antioxidant defenses can be intensively increased in response to
consumption of certain types of fruits. It was observed that
eating bilberry (Vaccinium myrtillus L.) fruit results in significant
increases of TAC in blood plasma. This increase occurs after
consumption of larger portions of fruits of at least 200 g. It was
observed that this effect was a result of activity of both hydrophilic
and lipophilic antioxidants present in fruit (Figs. 4 and 5)
[26].
Results show that plasma TAC value affected by the presence
of hydrophilic antioxidants increase significantly 1 h after blueberry
ingestion (tow200 mmole) and then falls below the initial
level after 4 h (Fig. 5).
