If your intuition tells you that “more intense color are richer,” science has good news for you

Cardiovascular diseases follow being the main cause of death in the worldbut this scourge can begin to control thanks to the most colorful foods of the supermarket. A new and thorough review study systematic published in Nutrients has put the focus on carotenoidsthe Natural pigments that give their vibrant color to fruits and vegetables such as tomatoes, carrots or spinach. What are exactly carotenoids. Carotenoids are a group of more than 600 compounds that plants, algae and some bacteria produce naturally. They are responsible for the red, orange and yellow tones of many foods. Among the best known we can highlight the lycopene that is very present the tomatoes, the beta-carotene that is in carrots (and can get to give us an orange color on the skin) and the Lutein o Zeaxantine that are in green foods. Components of great importance for humans. Humans cannot produce these carotenoids, as with some vitaminsso we depend on the diet to obtain them. But his fame is not free: they act as Powerful antioxidantsneutralizing the free radicals they produce Oxidative stress and ends up damaging the cells and the genetic material itself. In addition, the study highlights its anti -inflammatory properties or its ability to improve the cholesterol profile by reducing oxidation of ‘bad’ or LDL cholesterol. This is something very relevant, then The oxidation of LDL is the trigger to form the atheroma plates In blood vessels, which is a key risk factor for Atherosclerosis. That is, the hardening and obstruction of the main arteries of the organism that can finally cause a heart attack. Evidence on the table: real food vs. supplements. The researchers, led by a team from the European University of the Atlantic in Santander, analyzed 38 of the most relevant studies published in the last decade to answer a key question: does the carotenoid intake prevents cardiovascular diseases? But beyond this, they also wondered if The supplements that can be found work or a varied diet is better. Having them in blood is associated with a healthier heart. The observational studies of cohorts that followed large groups of people for years, are quite consistent: those who had higher concentrations of serum carotenoids presented, in general, a lower risk of cardiovascular disease. Specifically, there was an inverse correlation with hypertension, the rigidity of the arteries and several inflammation markers. This suggests that a usual consumption of rich foods in these compounds is a good cardiovascular health indicator. Do carotene supplements work? This is where the thing is complicated. The studies that gave the participants carotenoid capsules showed results that were often contradictory. On the one hand, when the lycopene was given in supplement, he recorded an improvement in the endothelial function of patients who already had cardiovascular disease, but not in healthy volunteers. In the case of lutein, a triglyceridesand with beta -carotene the significant effect was null. This is something that surprised the researchers, but even more they were amazed to see that by providing several carotenoids together the effect was more effective than with the use of an isolated carotene. This already gives us an important clue. Real food wins the game. The clearest verdict came from dietary intervention studies. When participants were provided with foods such as tomato or carrot juices, or they were indicated to increase the consumption of fruits and vegetables in the diet, the benefits were more notable and consistent than with the pills. Interventions with tomato juice in lycopene managed to reduce key inflammatory molecules in atherosclerosis, while increasing the consumption of fruits and vegetables improved antioxidant capacity of “good” or HDL cholesterol. In this way, scientific evidence suggests that carotenoids have to be consumed in ‘groups’ to have a greater effect. The conclusion is clear: we must not replace the vegetable. On many occasions we try to supplement what we do not like with herbalist treatments. This is not ideal in this case, since the cardioprotective effect of the carotenoid seems to be amplified with other compounds that the original food such as fiber or vitamins presents. But it also adds to the need to complement it with other fruits and vegetables. And you don’t have to become obsessed with tomato and carrot in this regard. There are a lot of fruits and vegetables that can be included in the diet in a varied way so as not to end ‘hating it: peppers, pumpkin, broccoli or kale are some of the examples we find. Time is vital for your protection. As in medicine, the effects are not usually immediate when a change in the habits of a patient is made. In this case, long -term observational studies show the strongest results, that is, It is the sustained habit of consuming these foods What really protects the heart. A good diet is fundamental. This conclusion is no secret to us, since there are many studies that point to important benefits of following a good diet. For example, the Mediterranean diet It can help us stop the aging of the brain. Although it is also a reality that there are many diets such as potato diet either Miracle diets In general, they are a pathology to face it in the absence of nutrients or a subsequent rebound effect.

They say nothing good who pronounces them, according to three experts

by

The language used is important because it predisposes and Define mental states with those who face the challenges and tasks. As noted Psychopedagogo Boris Gindis, language is the psychological function that intervenes in all other capacities such as perception, memory, cognition and behavior oriented towards the objective. That is, using a certain type of language can motivate people to follow a goal or, on the contrary, contribute to discouragement effort To achieve it. Three experts in linguistics, psychology and business management They shared with CNBC The three phrases that must be avoided at all costs if they want to achieve objectives and overcome professional challenges. Is what there is There is no phrase that best defines resignation to the established that “is what there is.” Although this might seem a neutral coletilla to an inevitable situation, its use often transmits a lack of interest for improving or lack of commitment to overcome the challenges that arise. In one Interview at the Podcast Unconfuse me Bill Gates, John McWhorter, writer and professor at Columbia University, explained that this phrase usually used when it really means ‘I don’t care’. “The first time someone told me that had happened to me something unpleasant, and he said: ‘Well, it is. As McWhorter points out, using this phrase can be perceived as a passive and defeatist attitude of resignation to something that a finger is not going to move to change. That will generate a negative image in others. Instead, Psychologist Cortney S. Warren formed in Harvard recommends Use a phrase with more proactive and committed connotations. Something like “I have to see reality as it is, even if it is not what I want, to be able to move on.” This approach recognizes the difficulty of the situation, but does not give up before her and denotes disposition to overcome and advance. This is how we have always done it Can you imagine how the world would be today if textile entrepreneurs during the industrial revolution would have said that phrase to the steam machine inventors? Use it in the work environment, and even in the personal environment, denotes a total lack of flexibility and a null Ability to adapt to new scenarios. This immobilistic attitude It clashes frontally with a period of deep changes in labor matters such as those that are currently taking place with the new models of remote or hybrid work and the imminent Arrival of AI to the working world. Jason Buechel, CEO of Whole Foods owned by Amazon, unravels that the biggest alert signal in an employee is when he is reluctant to accept new ideas or methods, stubbornly clinging to old practices. “To stick to a way of doing things, or not considering other people’s views, can significantly hinder your growth and hinder your company,” assures The Executive. Andy Jassy, ​​CEO of Amazon, acknowledges being a staunch enemy of the immobilist attitude that suggests this phrase, and bets on never stagnate to continue growing professionally. Jassy says that keeping curiosity and being open to new opportunities is not only beneficial for personal growth, but is also essential to maintain relevance in a constantly evolving work environment. Not resigning to a certain way of doing things and embrapping change, people can Maintain commitment and satisfaction both professional and personal. I can never do it. Why bother? Face a task that is perceived as impossible is the first step to not do it and the main entrance door to procrastination. Assume that the task is impossible to entry not only reflects a defeatist attitude, but ABPROVES PERSONAL SKILLS AND CAPABILITIES assuming that They are limited and cannot improve. The professor in Psychology at Yale University, Emma Seppäläholds a position close to Andy Jassy or Bill Gates, betting on a constant evolution of skills and improve in new areas, regardless of age or experience. This change of perspective is not only much more constructive, but also contributes to improving motivation and resilience, helping people overcome challenges that seemed impossible.

The tradition of work on any device With screen continues to surprise us. And throughout all these years we have seen the Software ID video game executed in increasingly extravagant pots. This time, the classic shooter has found a new home in a completely unexpected place: a Power Bank. And the most impressive thing is that it works much better than one would expect. What happened. Aaron Christophyl, creator of content known for his experiments with hardware, He has achieved Execute Doom in an Anker Prime Charger charger in 250W. This device, which is normally used to load multiple devices at the same time, has a 2.26 -inch color screen. And of course, for what but the screen of a Power Bank was going to take advantage of to run Doom. Why it works so well. The secret is in the bowels of the charger. The Anker Prime Charger incorporates a SYNWIT SWM34S processor with ARM Cortex-M33 nucleus to 150 MHz, 8 MB of RAM and 16 MB of internal storage. These specifications, although modest for current standards, are more than enough to execute a game designed in the 90s, when domestic processors worked at 25-33 MHz. Peculiar controls. The most ingenious part of the project are controls. The charger only has a rotating wheel next to the screen, but Christophyl has managed to map all basic functions From the game: turn the wheel to advance and go back, press and turn to move laterally, and click to shoot and open doors. Although it is certainly not the most comfortable method to play Doom, the truth is that it takes advantage of the wheel that incorporates the charger. No hardware modifications. The most remarkable thing is that this implementation does not require any physical modification of the device. Christophyl only used the purification port to load the game software, while the operation of the charger continues as is. In this way, you can continue loading any other device while adding the possibility of playing Doom. More and more crazy ideas. This case is added to the long list of unusual devices in which Doom has been executed over the years. From calculators and pregnancy tests until Specifies and Word documentsthe popular novelty shooter has become the final test bench for years to demonstrate the capabilities of any hardware with a processor. And what remains. Cover image | Aaron Christophyl In Xataka | The AI ​​entered video games as an experiment. Today more than 80% of developers no longer know how to produce without it

Having an AI browser that does things for you sounds good. Until a hacker uses it to steal all your money

by

Ask the AI ​​to make a summary of that article that you just saw in Reddit can be very expensive. It is what They just revealed Those responsible for Brave, who have discovered a surprisingly simple way to hack the browser of the perplexity comet to do not only what the user asks, but what an attacker has managed to convince him to do. The danger of leaving everything in the hands of AI is evident. What happened. Brave’s experts, a browser that competes with Chrome or Firefox and also has AI functions, wanted to analyze the risk of using an agetic browser like the one It offers perplexity right now with Comet. And what if they have done it. The browsers with ia promise a lot. Thanks to tools like Comet – Openai too has its chatgpt agentheir of Operator-, It is possible that the browser becomes a kind of digital butler and do things for us autonomously when visiting websites. Thus, you can summarize a news, tell you which song appears in that YouTube video, look for offers, answer emails or complete purchase processes. A priori the advantages are huge, but be careful, because there are also important risks. But be careful to let go of the steering wheel. However, delegating everything in the browser can raise a real threat to the safety and privacy of our data. If we trust them too much, these browsers may have access to all our data, since theoretically they will benefit from access to our email, but also to banking and financial data and even health. What happens if the amazing model or makes mistakes? Or worse: What happens if someone modifies the content in a malicious and invisible way for ia agents to follow malicious instructions? Having the AI. That is just what They discovered in Brave When trying a simple technique. They published a malicious comment on a Reddit thread, and then asked Comet to summarize the article. When they went to do it they verified how Comet did not know whether the content of that thread could or not contain malicious instructions: he simply met them and followed them. And in thread, as can be seen in the video, there were some simple instructions that stole the credentials of their perplexity account and even intercepted the verification code that the platform sent to the user to log in the service. Result: Automatic account by the attacker thanks to the AI. How the attack works. As Brave experts explain, the problem is that the way of hacking this type of browse is not hacking the browsers, but hacking the content, something that is very, very simple. The steps are the following: Configuration: An attack writes Malicious instructions in some content on the web. If you control that site, you can hide instructions using blank text if the background is also white, or in comments or other invisible elements. They can also do it directly “injecting” those instructions through comments in publications on social networks such as Reddit or Facebook. Activation: A user sails to that website and uses the browser with AI. If you do something simple as “Summarize this page“Or ask that certain information be extracted, these malicious instructions are activated. Injection: As the AI ​​processes the information on the page, see those malicious instructions and follow them. It is not able to distinguish whether the content has a malicious purpose or not, and considers everything as part of what you should do at the request of the user. Exploitation: these malicious commands and instructions indicate to the navigator’s tools to perform various actions, such as navigating the user’s bank account, Extract stored passwords In the browser or collect information to a remote server controlled by the attacker. Possible solutions. Those responsible for the study indicate that to protect themselves from these types of problems, agricultural browsers must first differentiate between what the user has asked for and what the user content is. The content of a website “should always be treated as non -reliable.” In addition, the browser with AI should necessarily ask for the user’s interaction to perform certain actions, how to access passwords or perhaps send an email. Restrict permissions to the agetic browser and make good use of Two -step verification systems “With mobile applications such as Google Authenticator, for example,” are also adequate ways to mitigate a problem that can put in many problems the deployment of these tools.

So much ice has melted in Greenland that the plankton has grown 40%. It is not good news

by

The Antarctica and Greenland have become two of the Climate change thermometers. The Ice loss in Greenland It is something that has been monitored for years because not only influences sea level: also in the Sinking of the seabed. It is estimated that Greenland’s glaciers have reached a point of no returnand its implications go beyond sea level. In fact, a recent NASA study He points out that there is a beneficiary of the thaw: the phytoplankton. And it is not good news. Short. A few months ago we commented that Greenland was getting greener. The estimates point out that, during the last 30 years, the region has lost 1.6% of its ice, which may seem little, but it is something equivalent to the Galicia area. The air temperature is about 3 higher Celsius degrees in the period between 2007-2012 than in 1979-2000, and That thaw It is causing a huge increase in fresh water. How much? According to the investigation of San José State University and NASA, of up to 266 million tons per year that are discharged into the sea, especially under the Jakobshavn glacier, the greatest in Greenland. It is the equivalent of 1,200 cubic meters of fresh water that are poured into the sea every second. As is fresh water, it is less dense and lighter than the salty, and what it does is like a whirlpool, dragging nutrients from the seabed to the surface. The study. These nutrients are mainly iron and nitrates, and it is phenomenal to phytoplankton. It is, however, an anomaly, and the researchers wondered to what extent that rapid growth of the plankton could affect the ecosystem. In it studypublished in Nature, detail how with the help of a model developed in the JPL and the MIT and using superoringers to accelerate the calculations, simulated the interaction between the water of the thaw, the nutrients and the phytoplankton. The greatest areas is where an increase in chlorophyll has been seen in recent years They have discovered that the growth of the body in the studied area increases between 15% and 40% in summer, at which time the maximum point of the thaw is given, thanks to those nutrients that the fresh water current sends to the surface. In total, NASA has observed That, between 1998 and 2018, the growth of phytoplankton in argic waters had increased by 57%. Consequences. On the one hand, that increase in phytoplankton can be positive for marine life, since it improves the basis of the ecosystem to be able to feed more animals, and also phytoplankton Atmospheric co -capture (that is not bad for us) To do photosynthesis. However, there is a paste: changes in temperature, chemical composition and water salinity can alter ecosystems. In the study they have not launched predictions about what will happen, but it is evident that it is a substantial modification of the marine properties of that specific area. Its conclusion is that those Changes in the Food Chain They can modify the composition of marine species, from bacteria to fish, affecting both the equilibrium of the ecosystem and fishing activities, which are a key engine for Greenland. Because phytoplankton is tiny, but it is the food of Kril and other small herbivores that, in turn, are the larger animal food baselike fish and whales. Only in Greenland? This study was carried out in a very specific area, that of the Jakobshavn glacier, but the results have similar implications for the more than 250 marine glaciers in the region and, possibly, for other glaciers that end in the sea in other regions of the world. Researchers comment that this simulation method is adaptable to other systems and that, therefore, it is likely that other areas where glaciers are pouring water into the sea They are also living, to a greater or lesser degree, a similar phenomenon, modifying ecosystems and affecting both fauna and fishing activities that are carried out in the area. Therefore, the thaw of glaciers is no longer that it affects only at sea level, but has the potential for alter the ecological balance of the regions in which it occurs. As they say, we were few and the grandmother gave birth. Images | POT In Xataka | 400,000 years ago all Greenland ice melted. The map he drew is not flattering

More and more voices think that keeping food in plastic is not a good idea

by

A kitchen that boards has a drawer up to numerous tuppers with the tapas on the other hand. Although it is not the only place, we open the fridge and find even more stacked: some keep the leftovers of noon, others contain freshly taken food from their original container. Behind this daily life – so assumed that goes unnoticed – hides an uncomfortable question: are we storing our food well? The plastic under suspicion. Light, cheap, resistant: plastic became the great ally of modern cuisine. However, recent studies call their safety when they come into contact with food. A BBC report He explained That thousands of chemicals are part of their composition and that some can migrate to food, especially when they come into contact with fatty, acid or hot foods. The problem is not only the food we keep, but also the use we give: the microwave, the dishwasher or the rayons due to repeated use accelerate the release of compounds. And microplastics. To them is added another invisible problem. As Delish magazine has pointed outtuppers release microplastics, tiny particles that have already been found in blood, lungs and even human placenta. A health problem. The debate about tuppers is not a simple kitchen detail: what is at stake is hormonal health. Many of the compounds that migrate from food plastics are classified as endocrine disruptors, substances capable of altering the balance of our hormones. The best known case is bisphenol A (BPA), used for decades in rigid plastics and linked to fertility and development problems. The European Food Security Authority (EFSA) recently reviewed its safety and reduced tolerable intake at a level 20,000 times lower than the previous one. Something similar happens with phthalates, employees to give flexibility to plastic and also associated with hormonal and reproductive alterations, As the BBC has detailed. Plans b. However, trusting alternatives is not a guarantee either. The Guardian He has warned that compounds used as BPA substitutes – the so -called BPS and BPF – have similar effects on the body. AND, According to a study cited by The I Papermore than 3,600 chemicals of plastic containers present in humans have been identified, many of them barely studied. Therefore, some expert voices are overwhelming. Lisa Zimmerman, from Food Packaging Forum, summarized it like this For the same medium: “If you care about your health, you should throw your plastic tuppers and use glass or steel.” The stations also influence. Beyond chemicals, summer heat adds another threat: bacteria. In statements collected by El Confidencialdietitian Judit Carreira, from the Sant Pau Hospital, explained that high temperatures favor food poisoning. Its advice is clear: transport the taperes in thermal bags or portable refrigerators, avoid exposing them to the sun and, above all, separating raw cooked in the fridge to prevent cross contamination. “When you return from the supermarket, the meat and the raw fish should be removed from the container and stored in a clean taper,” He has insisted. He also remembered the four basic food security rules: clean, separate, cook and cool. So, throw all my tuppers? It is not about emptying the kitchen, but of changing habits. Various media They coincide In a series of recommendations: Avoid reheating in plastic: although the container indicates “suitable for microwave”, heat accelerates chemical migration. Reserve them only for cold or dry foods, never for oily, acid or hot meals. Replace them if they are scratched, deformed or with persistent smell. Opt for glass, steel or ceramics for hot meals or prolonged conservation. Now, not all alternatives are perfect. Ceramics, although it is considered safe if it is certified, can be a problem in cases of artisanal productions. The mail reported a few months ago The case of a family of Getxo (Vizcaya) poisoned with lead after drinking for years of an enameled ceramic jug bought in Andalusia. Lead, prohibited in pottery since the 60s, can cause abdominal pain, anemia or neurological alterations. An easier life, at risk. It is true that tuppers have made our lives easier, but they have also exposed us to a chemical soup not yet known. Science still investigates the cumulative effects, but there is consensus on something simple: heat, fat and plastic do not combine well. Perhaps the true luxury of modern cuisine is not accumulating containers of all sizes, but choosing containers that take care of our health.

We have asked Renfe what alternatives we have to the cancellations of the AVE in Galicia. There are good and bad news

by

For sixth consecutive day, the high -speed circulation of the Galician corridor remains suspended. The service between Madrid and the Galician cities is provided only partially and in extraordinary frequencies. We have spoken with Renfe and consumer associations to know what their alternatives are. Sixth day without bird. Renfe cannot provide the high speed service of the Galician corridor as a whole. So The company itself confirmed it on its social networks but On its website Information about the latest news related to the railway situation between Madrid and Galicia is not found. No, at least, with a first glance. It is the result of the serious fires that are ravaging Zamora, León and Ourense, which They do not allow for sure to the high speed line. Given the impossibility of guaranteeing an improvement in them and, therefore, an opening of the line, Renfe confirmed almost at 11:00 am that all trains of today Tuesday, August 19, were suspended. Click on the image to go to the original tweet To (or from) Zamora. The solution that Renfe is giving is that passengers who prefer can travel from Madrid to Zamora or start their trip to the capital in the latter city, if it moves in the opposite direction. It is a patch that also requires adapting to Special schedules because the usual frequencies or schedules are not being fulfilled. Arriving in Galicia from Zamora or arriving in Zamora from the Galician community has already been in charge of the client. The latter is the one who has to look for life to take the train or reach its original destination. Something that, from Facua, they point out, should not happen. Buses? Jordi Castilla, Facua spokesman, explains that Renfe has the obligation to allow the change of ticket or its cancellation for free. Something that is already doing. However, it specifies that the company has to “relocate the person in an alternative environment without any cost.” From Xataka We have asked Renfe about this possibility and if they are valuing to include it in the next few days but we have not obtained an answer. Nor have those who In social networks they are asking Link Galicia with Zamora by bus since the main roads remains open. From Facua they emphasize that if the suspend and Renfe service does not offer this possibility, the client has the right to use a public transport means (such as a bus) and claim the money from the company. Not so a private transport, so the airplanes would be discarded. Cancellation expenses could also be claimed, such as a hotel night. What if I want to travel to or from Zamora? In Xataka We have contacted Renfe’s customer service. From Facua they point out that if we have a ticket with departure in Madrid to a Galician city and cover the journey to Zamora (or we start it in this city to Madrid) we have the right to receive part of the previously paid ticket. The same has been confirmed to us from the customer service of the railway company but, unlike the change of tickets or its cancellation, it cannot be done by telephone. In this case, you have to perform a online claim by filling out the form which is facilitated on the web or attending the office of the origin or destination station. Little in advance. Until now, Renfe has preferred to hurry until the last moment the cancellation of the trains. To the point that the confirmation that no train would circulate today in the high -speed line has not reached almost noon. That is causing many users to ask the company through social networks like Twitter what will happen to their tickets. The answer is repeated in that case: the client will be informed by social networks, mail and SMS. The telephone service and the website are being referred to change or cancel the tickets but in X only reference is being made to the confirmed cancellations and not to the trains that, it is not confirmed, if they will circulate in the next few days. What if I travel the weekend? In Xataka We have asked Renfe’s customer service if possible change or cancel a ticket for next Friday. They have confirmed that yes, there would be no problem even without the company having not yet confirmed the cancellation. From Facua they explain that in this, and in any other case, there is no minimum anticipation time with which Renfe or any other company must operate. “It remains in the good or bad faith of the company because if you know that it will be impossible to travel, you should inform you as soon as possible so you can look for alternatives and not have to adapt at the last minute.” Despite this, we can confirm that by telephone, these returns are being admitted even though there are still no confirmed cancellations beyond today, August 19.

We have been listening for years that “a glass of wine a day is good for health.” Science is clear that

by

Many times we have heard that “a glass of wine a day is good for our health.” We have also heard that “the Recommended alcohol amount It is zero”Who is right in this debate? The debates about the benefits and prejudices of a food are not exclusive to fermented drinks such as wine or beer. The relationship between eggs and cholesterol is a classic example but we can also find apparent contradictions regarding the consumption of coffeehe rice or the potatoes. Human health has many dimensions and our nutrition is very varied (even the poorest diets involve the consumption of a wide range of compounds present in the ingredients of the product or in their additions). Studying in detail The effect of each product is difficult precisely for this reason. That is why science often advances slowly, with the succession of seemingly contradictory studies that are actually simply refining the aim. However, the accumulation of these experiments is granting us a better idea of what happens in our body when we consume alcohol, even when this consumption is restricted to “a glass or two” wine. To better understand the debate, we can start asking us, what is good for wine? The idea that wine can be beneficial to our health is mainly based on polyphenolsnon -nutritious substances but with antioxidant capacity. These compounds present in grapes of which the wine is fermented, they can be beneficial to our health. The problem here is that There are non -alcoholic alternatives where these compounds are also present, such as must or grape itself. In part due to these compounds, it is usually attributed to wine Potential benefits About our cardiovascular health. Experts believe that this improvement could be due to the fact that these compounds favor the reduction of blood pressure and reduce cholesterol. Still there is some discrepancy in this regard among the different studies. A drink with risks Cancer is One of the main risks that are associated with excessive alcohol consumption. AND There are several types of cancer which have been associated with this consumption: in addition to the liver, alcohol consumption has been linked to oral cavity cancer, pharynx, larynx, esophagus, colorectal and, in the case of women, with breast cancer. “The response to whether the relationship between alcohol consumption and cancer risk is clearly established is that there is sufficient evidence,” said Marina Pollán, director of the National Epidemiology Center, in statements collected by Science Media Center (SMC) Spain. The risk, of course, “is proportional to the amount of alcohol ingested, being lower for moderate consumption.” But beyond cancer, excessive alcohol consumption has been conventionally linked to the appearance of the Hepatic cirrhosis (which can also lead to cancer). This disease It arises with the formation of “scars” in our liver, and can also be caused by hepatitis. While we link moderate consumption of wine to an improvement in heart health, alcohol consumption can have an opposite effect. This has also been related to the appearance of alcoholic myocardiopathy, arrhythmias and other heart problems. It should not forget the relationship between alcohol consumption and mental health problems such as addiction itself, being able to exacerbate existing problems. Various studies made in recent decades They have pointed out Alcohol as psychoactive substance More harmful In social terms. One of the most outlined studies in this field was carried out in the United Kingdom and Posted in 2010. Posted in The Lancetits results indicated that this was not so much to the damage it generated in the individual (in this sense it was overcome by heroin, the crackand methamphetamine), but for its social cost. However, these risks are generally manifested after consumptions that we consider “excessive”, in contrast to “moderate” consumption that is often promoted. The problem is that, beyond social conventions or recommendations perhaps without excessive scientific foundation, we do not know if there is such a thing as moderate consumption. According to the Monograph Alcohol 2021. Consumption and consequencesof the Spanish Observatory of Drugs and Addictions, this border does not exist, or in the words of the text itself: “There is no level of risk consumption free of risk.” That is why the health authorities speak not of “moderate” consumption but “low risk” consumption. The risk is never zerobut it is possible to keep it low. And how much is considered “low”? According to the report limits of low alcohol risk consumption, this would be two standard drink units (UBE) in men and one in the case of women. These “standard” measures are equivalent to 10 g of alcohol or, in terms of wine, approximately a 100 ml glass. It is not the same to ensure that moderate alcohol consumption is compatible with a healthy life than to say that this moderate consumption is beneficial to health. Nor is it the same to say that wine can generate a specific benefit in our well -being with ensuring that this possible benefit can be greater than the risks involved in this or other alcoholic beverages. As we pointed out at the beginning, alcoholic beverages (like any other food) contain a myriad of compounds, some harmful, other beneficial for their operation. The general consensus is that the damages of compounds such as alcohol are superior to the benefits that others such as polyphenols can provide. In short, a glass of wine a day can hardly kill us, but We must be aware of the risks They are associated with her. As always, a balanced diet and an active life can always help us reduce our risk of suffering certain diseases, perhaps even helping us to compensate for these small excesses that we can incur.
