Potential protective effect of moderate wine consumption on cognitive decline

A Spanish systematic review and meta-analysis identified a possible protective effect of moderate wine consumption[1]  on the development of cognitive decline. The authors caution, however, that the results do not suggest that the population should increase their wine consumption since this could be harmful. However, considering their results, low wine consumption could be promoted among other lifestyle factors, including the Med Diet, as an effective habit to prevent or delay cognitive deterioration in the healthy population. They also suggest that their findings support the international guidelines of low-to-moderate consumption of alcoholic beverages as the most acceptable level of consumption, both in the short and long-term and for people who do not suffer liver disease, are pregnant or take several medications.
