Recently Tyrosol present in white wine is also shown to be cardioprotective. Samson et al. has shown that tyrosol-treated animals showed significant increase in the phosphorylation of Akt, eNOS and FOXO3a. In addition, tyrosol also induced the expression of longevity protein SIRT1 in the heart after myocardial infarction in a rat MI model. Hence tyrosol's SIRT1, Akt and eNOS activating power adds another dimension to the white wine research, because it adds a great link to the French paradox. In conclusion these findings suggest that tyrosol induces myocardial protection against ischemia related stress by inducing survival and longevity proteins that may be considered as anti-aging therapy for the heart.<ref>{{cite journal |author=Samuel SM, Thirunavukkarasu M, Penumathsa SV, Paul D, Maulik N |title= Akt/FOXO3a/SIRT1-Mediated Cardioprotection by n-Tyrosol against Ischemic Stress in Rat in Vivo Model of Myocardial Infarction: Switching Gears toward Survival and Longevity.|journal=J.Agric.
