When an agave plant has been fermented and distilled, the result is tequila. Although agave may provide various health benefits, including possible cancer-fighting properties, there is some debate as to whether the agave found in tequila has lost these properties. The distillation process removes any carbohydrates from the liquor, but it also removes all of the immune-boosting antioxidants. For this reason, you’re probably better off avoiding silver tequila.
The Benefits of Wood Aging
However, reposado tequila and añejo tequila, are varieties that have been aged in wood barrels after the distillation process, and it is believed that the wood transfers antioxidant properties back into the liquor. Because of this, you might be able to indulge in tequila occasionally, but beware: one small study found that a daily serving of tequila over a period of 30 days increased insulin sensitivity.
We still don’t recommend going crazy on the margaritas, but if you really love tequila, there doesn’t appear to be a reason you can’t enjoy it as an occasional treat. Mark Sisson has a guide to the best and worst liquors to include in a Paleo/Primal way of living.
