5 things science still doesn’t know if they are beneficial or harmful to health

There are some products or habits that science has not yet decided whether they are beneficial or harmful to health, since studies have found several pros and cons, something that only demonstrates how complex the human body is, such as its reaction to external influences.


Coffee impacts the brain, but it has several benefits (Image: ijeab/envato)

Several studies have already highlighted benefits of coffee, such as reducing diabetes, burning fat, preventing Alzheimer’s and protecting the liver. However, a study published in Cerebral Cortex reveals that drinking the drink can alter the volume of gray matter in the brain. In addition, researchers have already announced that, in the short term, coffee helps with attention and alertness, but in the long term, it has the opposite effect, making a person even more tired.


Wine may protect from Covid-19, study finds (Image: Microgen/Envato)

You’ve probably heard about the benefits of having a glass of wine a day, making a person less prone to heart disease than people who completely abstain from alcohol. However, according to research published in National Library of Medicine reinforce, this is not because of the antioxidants present in the wine. What happens is that people who drink little tend to have healthier habits, in general, something that directly influences the results of the studies.

On the other hand, another article published in the same scientific journal points out that high consumption of red wine, white wine and champagne (one to four glasses a week) can lead to an 8% lower risk of contracting covid-19. Consumers of fortified wine face a 12% lower risk of infection. The theory is that this protection comes from the high content of polyphenols, organic compounds present in grapes to protect them against insects, ultraviolet radiation and microbial infections.


Psychotropic drugs like LSD are also targets of research, but there is still a long way to go (Image: microgen/envato)

Psychotropic drugs (those that act on the brain, impacting sensations) spark a real division of opinion, but recent studies have looked at the benefits. In February, scientists administered small doses of LSD to zebrafish, animals that share 70% of their genes with humans. The researchers discovered the possibility of using the substance as a treatment for mental health and alcohol addiction.

Meanwhile, a study published in 2021 linked mushrooms, LSD, and ayahuasca with a lower likelihood of heart disease and diabetes.

Rehabilitation centers also divide scientists. According to a study published in Journal of the American Medical Associationonly 43% of people complete their initial treatment program, and of those, 40% to 60% relapse within a year of release.

On the other hand, there are several reports suggesting that rehab saves lives and works by taking the individual off drugs. As a result, research is ongoing on how to make rehabilitation more effective. For now, science still doesn’t have a verdict.


Stress impacts every system in the human body (Image: microgen/envato)

Stress acts directly on the brain, which triggers the release of a cascade of hormones such as cortisol, adrenaline and norepinephrine, which produce physiological changes. Amazingly, it serves to help people react or deal with a threat to be faced. However, due to its impact on all systems of the body, science sees several harms.
