Researcher study: Moderate wine drinking can protect the brain from cognitive damage


Doctors are studying the protective effects of wine on the human brain
In recent years there have been various opinions about the effects of wine on our health. Researchers have now found that wine appears to have a protective effect on the human brain. The effect can be described as a kind of anti-aging effect for the brain.

Scientists at the Institute of Food Science Research in Madrid found that red wine helps delay the onset of cognitive impairment in aging and neurodegenerative diseases. The experts published the results of their study in the journal "Frontiers in Nutrition".

Red wine with polyphenol antioxidants slows cognitive impairment
Moderate consumption of red wine with so-called polyphenol antioxidants, especially as part of a Mediterranean diet, can slow down cognitive impairments, the study authors write. This could also be beneficial for neurodegenerative diseases such as Parkinson's and Alzheimer's disease. There is also a substance in red wine and chocolate that appears to prevent age-related memory loss. This substance is called resveratrol, the researchers say.

Experts are studying the neuroprotective effects of wine
In order to understand the molecular mechanisms behind the neuroprotective effects of wine, doctors in Spain analyzed certain compounds after the wine had passed through the human intestine. These compounds are found in people's urine and feces, and if they consume wine regularly, the scientists add.

Wine seems to protect the brain from the negative effects of stress
To study the effects of these metabolites on the human brain, the connections of human cells were added under stress conditions. This situation was comparable to the initial phases of certain neurodegenerative disorders, the scientists explain. It has been shown that the wine metabolites protect the cells from death as a result of the stress conditions.

Individual gut microbiota influence the neuroprotective effect
The exact composition of the wine metabolites influences the neuroprotective effect, explain the doctors. This composition in turn depends on the composition of the individual gut microbiota. In other words, wine is broken down into different metabolites depending on the intestinal flora of each individual, the authors add. This underpins the idea that different people can benefit from their food in very different ways, explains author Dr. Esteban-Fernández from the Institute of Food Science Research in Madrid.

Different people benefit from their food to different degrees
This individual difference is a factor that should not be neglected if we want to understand the health effects of certain foods, the expert adds. The results show that understanding the effects of food on brain function is urgently needed, Dr. Esteban-Fernández continues.

Proper nutrition can prevent diseases and health degradation
The current study confirms that nutrition must be seen as an important factor in maintaining health and preventing disease. The particularly beneficial antioxidants are contained in colorful fruits and vegetables, such as apricots, carrots, sweet potatoes, peppers and green leafy vegetables, the authors add. (as)
