I wouldn't advocate for abstinence over education, and I usually feel like our understanding of human health and nutrition is comparable in sophistication to alchemy; but to add some nuance to the counterargument to what you said, I'll suggest that whether we will live before we die is only one of the important questions, that (a) how long we'll live, and (b) the total number of happy, easy, healthy years we'll have before we die, are also important questions. Until the science is more reliable, moderation seems like the safe bet.
