This media article looks into the effect of a glass of wine to the mind. According to the article, a glass of wine can not only help clear the mind after a busy day, but also help clean the mind as well. According to the article, new study shows that low levels of alcohol consumption tamp down inflammation and helps the brain clear away toxins, including those associated with Alzheimer’s disease (University of Rochester Medical Center, 2018).

People would be interested in reading this article because it gives a totally different dimension of what alcohol is known for. While many people consume alcohol, not much health benefits is attributed to the drinking. In fact, alcohol is known for adverse health effects on the central nervous system, liver (cirrhosis), impaired judgment, blurry vision, infertility and even cancer and it is also considered a religious taboo to take alcohol. However, this article gives boozers and pro-alcohols an encouragement while also giving critics something to ponder. The article advises that for the first time, it has been proven that low doses of alcohol are potentially beneficial to brain health, namely it improves the brain’s ability to remove waste. Consequently, contrary to what many people believe, the findings link lower levels of drinking with a reduced risk of cardiovascular diseases as well as a number of cancers. Baring in mind that most people shy away from consuming alcohol because of its adverse effects, many will be inclined to follow the article’s advice, having a positive mindset regarding the effects of alcohol.Annotated Bibliography on Science Daily Article

However, the information presented by the article is not authoritative because it disregards the addictive nature of alcohol. It does not take into consideration the fact that it is almost impossible to be confined in the low doses of alcohol used by the researchers. Achieving only two and a half drinks may not be what an alcoholic would want. Alcohol is not just addictive, but it is always the user’s desire to take just enough to give the buzz feeling.

The scientific study saw experiments conducted on mice. A number were exposed to low levels of alcohol consumption and others high. The impact of both acute and chronic exposure were analyzed and observation was made on the levels of molecular marker for inflammation, particularly in cells called astrocytes which are key regulators of the glymphatic system, impairment of the animal’s cognitive abilities and motor skills.

This article gives an insight on the effects of acute chronic ethanol exposure and withdrawal from chronic ethanol exposure on the brain system. While admitting that chronic alcoholosim adversely affects the brain by decreasing white and gray matter and increasing the cerebrospinal fluid, low doses of alcohol may be beneficial to one’s health. It results to reduced risk of cardiovascular diseases as well as a number of cancers and increased cerebral blood flow plus a reduced risk of dementia. According to the authors, acute eposure to small amounts of alcohol boosts glympatic function by speeding and enhancing effeciency in which waste products and metabolites are transferred from the intercellular space of the brain and drained into lymphatic vessels of the head and neck. On the other hand, chronic exposure to alcohol is inhibitory to the glymphatic process.

In reaching the conlusion, the researchers collected data from experiments done on mice. Awake, behaving C57Bl6 mice received low, intermediate, and high doses of alcohol (0.5, 1.5 and 4 g/kg respectively) 15 minutes before injection of CSF tracers into the cisterna magna compartment via a cannula implanted 24 hours earlier. The brains were quickly harvested at 30 min after the tracer injection and immersion-fithey were then passed through a microscope and observations revealed that the low-dose alcohol group (0.5 g/kg) exhibited a 39.8±2.8% increase in CSF tracer infux compared to vehicle controls the intermediate (1.5 g/kg) and high acute alcohol doses (4 g/kg) which suppressed glymphatic function by a mean of 33.5±3.0% and 28.0±6.0%, respectively. Based on the data presented, I agree with their interpretation of the data that proved a little consumption to alcohol may be beneficial to the brain. However, as long as the consumers cannot be restrained to only a little of it, then the side-effects will always outweigh the benefits.Annotated Bibliography on Science Daily Article

The conlusions reached by the popular media authors are in one accord with those reached by the scientist authors. The only notable differences is that the media article solely focuses o the beneficial part of acute alcohol consumption while the scientist authors are keen to emphasize on the limited intake that would be beneficial. The authors acknowledge the adverse effects of intermediate, and high doses of alcohol, making it imperative that the research is almost impossible to achieve.

In my opinion, the scientific legitimacy of ScienceDaily should be placed under scrutiny as it appears they are more into rousing excitement other than setting vivid and reliable scientific facts. Readers are likely to be mislead by merely reading headlines which are not wholly trustworthy. For instance, the failure to be categorical on the little dosage on amount of alcohol that is said to be beneficial may lead one to indulge in excessive consumption believing it to be beneficial.
