Citando:
"They say past studies have shown that low-to-moderate intake of wine can delay the onset of neurodegenerative diseases such as Alzheimer’s and Parkinson’s but wanted to investigate the reasons behind it.So instead of examining wine directly, they looked at metabolites – the compounds that are left after the wine has passed through the gut.
The scientists then added these metabolites (extracted from waste samples from regular and moderate wine drinkers) to human cells under stress conditions resembling the initial stages of some neurodegenerative disorders.
In their experiment, they found that these metabolites were actually protecting the cells from dying.
According to the study, different intestinal flora – the microorganisms in your digestive tract – created different metabolites.
So basically, the gut bacteria influenced whether or not wine broke down into these protective compounds, suggesting that drinking a glass of pinot noir does not guarantee you will reap neurological benefits.
“Differences in our gut microbiota are leading to the different metabolites – which underpins the idea that humans benefit from food in different ways,” Dr Adelaida Esteban-Fernandez said."
