[edit] French Paradox
French Paradox refers to the potential health benefits of moderate wine consumption, because of the low risk of coronary heart diseases in moderate wine drinkers. This observation was associated with resveratrol, which was reported to activate Sirtuin (or Sir2) protein, a histone deacetylase implicated in anti-aging or prelonging life-span [1][2][3]. Sirtuin activation, however, has been the subject of controversy [4][5]. Even when it is true, the biological activity of scarce (less than 5 mg/l) and rapidly metabolizing resveratrol in wine needs further study. In more recent study, resveratrol is known to inhibit COX-1 (cyclo-oxygenase-1) and COX-2, NAD+-dependent histone deacetylase SIRT1 (sirtuin 1) and QR2 (quinone reductase 2) [6].
