Not none "Among younger men, the range of protective effects was minimal, with a significant reduction in hazards present only among those who reported consuming 15.1-20.0 units/average week (hazard ratio 0.49, 95% confidence interval 0.26 to 0.91) or 0.1-1.5 units on the heaviest day (0.43, 0.21 to 0.87)" A hazard ratio of 0.49 means your chance of dying is halved. That seems like a very significant benefit to me. As a comparison in this study the hazard ratio for all-cause mortality for engaging in a very high volume of exercise is 0.65 http://www.hivdent.org/_nutrition_/2011/PIIS01406736116074962.pdf http://www.hivdent.org/_nutrition_/2011/PIIS0140673611607496... (the 95% confidence interval for the exercise study is much narrower though)
