Don’t believe what you read or hear from the media. Just use your own, very valid common sense.
Reporters and journalists, always on the lookout for stories that will sell or get readers and viewers, are happy to report the latest “news” about food. Most such “studies” are based on unscientific, cherry-picked data, if any data at all, and get published (for a hefty fee paid by each author) in disreputable medical journals.
If you trust the latest “news,” anything that you can ingest will either kill you or guarantee your immortality.
Is it true that drinking a glass (or, is it two glasses?) of red wine (or, is it white wine?) per day will improve cardiovascular health? No. If there’s any connection at all between wine consumption and health, it’s most likely the fact that more affluent people, who have good lifestyles and access to responsible medical care, are in the same demographic of people who drink wine.
