We have been obsessed with doing more hours of sports for years. Science points out that we were wrong

by

For decades, the main message that medicine has conveyed to us is that physical exercise should be a priority and it has been summarized with one word: move. Accumulating hours of activity per week has been the great objective that many have had; However, a new study has come to turn this around, to give great importance to the type of exercise and how varied the training menu we follow is when we go to the gym. More and more complete. As we investigate more, the way we exercise is changing, and now a study published at the end of 2026 has suggested that combining different types of exercises reduces the risk of mortality, regardless of whether we do a lot or a little sport in total. That is why the message we must keep in mind is that, instead of doing many hours of a single exercise, it is worth diversifying a little between different modalities, dedicating a little time to each of them. How they have done it. To reach this conclusion, the research team used data from two large groups of people to bring together more than 100,000 people who were followed for more than thirty years. In this way, with different questionnaires, the team measured the active time that each of the people to be analyzed had, establishing a minimum threshold of 20 minutes of activity per week to estimate that someone was really doing it and that it was significant. The objective was to find a correlation between activity levels, the number of these activities and, above all, how they reached adulthood and even when they died in the event that they had not reached the end of the study. The results. The most striking finding is that the group of people who practiced a greater variety of exercise had 19% less total mortality compared to those who limited themselves to a single repetitive routine. But the most important thing is that this good effect of variety in activity is independent of the total volume of time invested in playing sports. That is, the mere fact that exercise is varied has a protective effect in itself, reducing the risk of dying from cardiovascular, respiratory, cancer and other pathologies by between 13% and 41%. The best sports. The study also broke down the individual impact of each discipline, showing a non-linear dose-response relationship, making the greatest benefits noticeable at the beginning, when we went from doing nothing to doing something. In this way, the best sports according to science are the following: Walking: 17% less risk. Racquet sports (such as tennis): 15% less risk. Rowing and calisthenics: 14% less risk. Weight lifting: 13% less risk. Jogging/Easy Running: 11% less risk. Cycling: 4% less risk. Its limitations. Logically, this note has important limitations, since the data were self-reported by the participants with questionnaires and the population analyzed was not too varied, being mostly white, so we must look to see if these percentages may vary by demographics. However, the consensus is clear, since just as nutritionists have been recommending for years that we eat a “rainbow” of different vegetables instead of gorging on just spinach, sports science is now asking us for an “omnivorous movement diet” in which we combine different types of exercise on a daily basis.

The US is obsessed with achieving General Artificial Intelligence before China. China couldn’t care less

by

The promise of the AGI has become the “the wolf is coming” from some AI companies. The gurus of American AI companies do not stop hype with the long-awaited general artificial intelligencethe one that will surpass humans in all areas of knowledge. Meanwhile, In China it doesn’t seem to matter too much. The AGI gap. Elon Musk, Dario Amodei, Sam Altman…everyone agrees that the AGI is about to fall, or so they have said at some point. We cannot know how close they are, what we do know is that to achieve AGI they need more computing power, for which they need a lot (more) money. The AGI as a justification for an insane investment. They count in High Capacity that China barely mentions AGI in its 2025 AI+ initiative nor did it mention it in the ‘Next Generation AI Development Plan’ 2018. AI is a strategic technology of great importance, but they focus on specific applications such as industrial automation, autonomous driving or robotics. Transformative, yes, but not turning points that will change the world completely. Whoever arrives first wins (or not). It’s American logic in this race. To achieve this, they are betting everything on one horse and AGI is the goal. If they arrive before, they will obtain an insurmountable economic and military advantage: they will have won. On the other hand, if China arrives before, the power relationship would change completely. The truth is that things have to go a lot wrong for the US to not win this race. The problem is that, while they are making this titanic effort, China is beating them on other fronts such as the electric car, industrial robotics, drones, solar panels… Win the AI ​​battle, but lose the economic war. China is calm. Why aren’t China so excited about AGI? To begin with, it is not so clear that scaling the models is the fastest route to AGI and that requires a gigantic investment with no guarantees. But above all it is because they do not buy the idea of ​​”arriving first”; Even if the US overtakes them, they can simply copy them and catch up quickly. Yao Shunyu said itchief AI scientist at Tencent: “History shows that once a technical pathway is validated, Chinese teams can quickly replicate it and even surpass it in specific areas, such as electric vehicles or manufacturing.” The question is not so much who gets there first, but who makes the best use of it. Who does talk about AGI in China. Yao Shunyu’s statements occurred within the framework of the AGI-Next Summit, where several leaders of Chinese AI companies met to talk about the future of the sector. Figures such as the founder of DeepSeek, the CEO of Ziphu or the founder of Moonshot have talked about their goal being to achieve AGI, although they have not shared many more details. Maybe the company that Alibaba has gone deeperwhich gave a presentation detailing its plans to achieve superintelligence (ASI). These leaders, like those of American companies, may have commercial motivations in these statements, but there are other organizations in China that are investigating this field such as the Beijing Institute for General Artificial Intelligence or the Chongqing Institute for General AI. There are initiatives, but there is nowhere near the level of obsession that they have in the US. A restful strategy. While the US hoards chips and scales like crazy, in China they are choosing to do it more slowly. They are prioritizing national chips and open source with the idea of ​​promoting the adoption of their models. It is a more long-term vision. A long distance race, not a sprint.

There is a “nihilistic” penguin who decided to embrace certain death. The Internet has been obsessed with him for weeks

by

If in many years some historian were to investigate how the world has started 2026, they would find one of those surprises that raise eyebrows: humanity (or at least that part of humanity that rubs shoulders on the Internet) has started the year fascinated by a “nihilistic penguin”. With Ukraine at war, Trump threatening to annex Greenland to the US (by hook or by crook) and Nicolás Maduro detained In a New York prison, half the planet is dedicated to speculating why the hell one fine day in 2007 a palmiped from Antarctica undertook a suicidal trip that would have inspired himself Friedrich Nietzsche. It sounds bizarre, but it makes sense. What the hell is that penguin doing? It sounds bizarre, but for weeks thousands of people around the world have been asking themselves that same question: What is that penguin doing? The bird in question is a Pygoscelis adeliaean ‘Adelia’ like there are thousands of them in Antarctica, but which about 19 years ago came across the German filmmaker’s cameras by pure chance Werner Herzog while recording his documentary ‘Encounters at the End of the World’. The film lasts almost 100 minutes during which Herzog shows snowy plains, seals, underwater scenes and a multitude of frozen landscapes. At one point, however, his camera captured something curious, a detail that caught the attention of some critics years ago and now it has revolutionized half of the Network. The scene shows an Adelie penguin doing something totally counterintuitive. Without us knowing very well why, the animal begins to walk with a firm step away from the rest of its flock, entering between frozen mountains. Ahead, nothingness. No company. No food. That is, death. “But, why?“ The scene is shocking. First because it seems to go against the most basic common sense. At least the human one. Second, because of the surprising determination of the penguin, who sets off on his way without hesitation and only for a brief moment seems to stop to look at everything he leaves behind him. The third reason why it has captivated half the Internet is because Herzog himself was in charge of giving it importance and highlighting its drama. “But why?” he wonders the German filmmaker in the narration that accompanies the scene. After all, he only has miles and miles and miles of barren land ahead of him that take him further and further away from the safety of his colony and food sources. “It caught our attention. It wasn’t heading to the feeding grounds at the edge of the ice or returning to the colony. Shortly afterwards we saw it heading towards the mountains, 70 kilometers away. Dr Ainslie explained that even if he captured it and brought it back to the flock, it would return to the mountains. But… Why?” fascinated account Herzog. The full question would be a little longer: Why the hell would a penguin ignore its own survival instinct? There must be a reason, right? That is exactly what the documentary filmmaker proposed at the time and it has been worrying half the world for weeks. There is who has speculated that the penguin perhaps had a problem that altered its orientation or an ailment that affected its behavior. There is even talk of possible changes at an environmental level or of a exploratory instinct unconventional. If the panorama were not disturbing in itself, add Ainslie’s disturbing observation: it does not matter that Herzog or anyone else tried to correct their course. The animal would begin its deadly journey again almost instantly. Click on the image to go to the tweet. Is this something so strange? The penguin’s attitude does. Our attempts to find an explanation that fits our way of seeing the world (often from a anthropocentric optics), No. We humans have been debating for some time whether animals have something similar to a sense of morality. For example, we ask ourselves if in episodes that seem to us cruel There is a latent intention or they are simply the result of instinct. We have even speculated on the possibility of “altruistic” behavior in fauna. It may sound strange, but these are questions that have arisen in view of specific behaviors. A crow that finds a large amount of meat and decides warn others companions to share the feast, a whale investing time and energy in protect a seal harassed by killer whales, a duck that cares for a cub of another species, even putting itself in danger. Are those animals being generous? Are they selfless or do they act motivated by an instinct that, ultimately, seeks the preservation of themselves and their species? These are issues so complex that they have even given rise to scientific studies. What does it have to do with the penguin? Well, in recent weeks, after Herzog’s video once again gained popularity on the internet, many people have seen a 100% human attitude in the palmipede. Of course, one that has little or nothing to do with altruism or cruelty. What they appreciate is pure nihilismthe doctrine that embraces “nothingness” (hence its name, ‘nihil’) and denies the pillars on which philosophers have relied for centuries: the existence of religious, political and social principles and, in general, any foundation in morality. There is no purpose. Not even life has a meaning like the one that religions have sought for centuries. And what does Herzog’s penguin do if he doesn’t embrace that very thing, nothingness? Does it not evoke, in words by journalist Adil Faouzi, “a willful desertion of the logic of life itself”? The animal recorded by Herzog seems to capture these ideas so well, to condense them in such a powerful way, that many have nicknamed it: the “nihilistic penguin”. A little far-fetched, right? Depends. We do not know what motivated that small creature to undertake a journey towards its own death and who have tried Finding an explanation points (as we said before) to a possible illness or some type … Read more

There are people obsessed with consuming magnesium as a supplement when the best way is to put it in your diet

by

We live in the era of biological optimization, where The strange thing without a doubt is not taking dietary supplements from the supermarket such as magnesium, collagen, calcium, various vitamins… Magnesium in particular is sold as an almost magical way of sleep betterreduce anxiety and recover muscle. But the truth is that we are forgetting the most important thing: We have all this in food. The reminder. With so many food supplements (which often do not come cheap), sometimes we forget that we have these nutrients in the supermarket in different presentations. This is something in which Doctor Federica AmatiChief Nutritionist at ZOE Science & Nutrition, has put its finger on the sore spot of the supplement industry: For the vast majority of the population, there are plenty of pills and no food. Why magnesium matters. There is an obsession with taking this mineral, and the reality is that it makes sense because its functions are critical for our body to function correctly. Its fundamental role in many metabolic reactions of the body makes it essential for human survival, since without magnesium we would literally be extinct. And it is no wonder, because beyond being used to prevent cramps, it has important functions in energy production, DNA synthesis, metabolic control such as glucose levels, and also structural function by allowing bone to develop. Given its importance, the consumer logic seems simple: “If it’s so important, the more you take, the better”. But this is where science has to put the brakes on because a large amount does not always equal better performance. The best foods. One of the positions that we can have on the table right now is that magnesium supplements (and even others) are not necessary, unless it is known that there is a deficit. All this because it has a big problem: they are isolated. The problem with supplements is that they are isolated. NIH Office of Dietary Supplements (ODS) emphasizes that the food matrix It is irreplaceable. When you get magnesium from an almond or spinach, you’re not just ingesting the mineral, you’re getting fiber, phytochemicals, and other micronutrients that work together and that no pill can fully replicate. The daily doses. The official recommendations today indicate that the minimum levels of magnesium They are not unattainablesince for adult men between 400 and 420 mg per day are needed, while for women between 310 to 320 mg per day is sufficient. Low figures mean that they cannot be easily achieved with food by adjusting the shopping list without going to the pharmacy. Where can it be found. If the goal is to reach 400 mg daily, the strategy is not to look for supplemented foods, but to go back to the basics. In this case, science points because the food where we have the greatest amount of magnesium are seeds and nuts, where we find almonds, cashews and especially pumpkin and chia seeds. But in addition, it should also be noted that green leafy vegetables such as spinach or chard have chlorophyll in their composition, which also acts as a highly coveted magnesium reserve. All this without forgetting legumes and whole grains. Who needs supplements. Logically, they have a site, but it is by no means a universal recommendation for everyone who may have their requirements met with the diet. According to the ODS, there are different groups of people who may require this supplementation (under medical supervision). These are the following: Gastrointestinal disease such as celiac disease where nutrient absorption is compromised. Type 2 diabetes, since its pathophysiology causes a decrease in magnesium. Chronic alcohol consumption. Elderly people where absorption is naturally decreased. In these specific cases, the evidence indicates that supplementation can help improve parameters such as sleep quality or anxiety, but because they have an absorption problem. A previous visit to the doctor. Before starting supplementation of any type, it is best to go to your primary care doctor to verify in a blood test the nutritional deficiencies that you want to counteract. And our body does not store these minerals, meaning that anything taken in excess has no effect whatsoever. In Xataka | Which dietary supplements really work and which don’t, in a great graph

Toyota was obsessed with creating its best electric sedan. So he ended up asking Huawei for help…

by

After letting it be seen in the Shanghai Auto Show At the beginning of last year, Toyota just made official the bZ7its electric flagship more than five meters long. What is striking here is not the car itself, that too, but the technology that gives life to both its software and its drive train. Technology that… is not from Toyota. The car. bZ7, this is the name that Toyota has given to an electric sedan that embodies the latest technology available for this segment. The summary is simple. 5.1 meters long. 1.9 meters wide. LPF (lithium ferrophosphate) type batteries of BYD origin. Autonomy of between 600 and 800 km (according to the Chinese cycle, CLTC) depending on version. Operating system HarmonyOS. Huawei DriveOne system (electrical system, engine, car architecture…) What’s Huawei looking like here?. In 2020, Huawei confirmed its commitment to the electric car with DriveOneits first electric motor. Specifically, we are talking about a control unit composed of a motor, reducer, converter, integrated charger, power distribution unit and battery control unit. It thus allows this Toyota bZ7 to have a power of 278 HP and a maximum speed limited to 180 km/h. All this in a much more compact platform compared to the traditional ones used in this type of vehicles. The interior. As if it were not enough to power the engine of this luxury sedan, the cabin has a 15.6-inch floating central screen. The size of a generous laptop. The operating system that gives it life is HarmonyOS, a platform thatthe company develops for the world of electric cars, smartphones, tablets, computers and peripherals of all kinds. The alliance. That Huawei and Toyota develop a car together is something quite recent. The Japanese company announced that, on cars destined for China, it would cooperate with Huawei. Toyota began to lose steam both in global sales and in China, where it fell 6.9% in 2024. After three consecutive years of losing sales in China, it decided with one of the manufacturers that today has more muscle when it comes to developing complete platforms for electric cars. Beyond Apple and Google. Chinese manufacturers like Huawei are betting on a solution at the operating system level that is much more integrated than what Apple and Google have been trying to do for years. Unlike Android Auto and Apple CarPlay, integrate the system (in this case HarmonyOS, but also in cases like that of HyperOS), allows complete control of the vehicle from it. It does not require a smartphone, it is updated via OTA, it is based on its own code… It’s something similar to what Google is trying with Android Automotivea complete system but with little adoption, and what Apple promised with CarPlay Ultracurrently reserved only for luxury vehicles.

We have been obsessed with microplastics for years. There are more and more scientists who believe that there is something wrong

by

Up to 18 studies that affirmed the presence of microplastics in human organs they have just been challenged due to possible technical and control failures. And, although we have been obsessed with them for years, the truth is that it should not surprise us: we have known it almost from the beginning. Studies suggesting its presence in arterial tissue or in the testicles they have been receiving public criticism from the beginning. And the famous study that talked about the presence of microplastics in the brain was pure scientific fraud. None of this invalidates environmental concern, nor does it deny human exposure to these types of particles. It simply indicates that we have gone too far. And what is there many people taking advantage of it. What exactly happened? So far this decade, environmental contamination by microplastics has become a central issue that has not only generated a research boom, but has also promoted rules and regulations. And it is logical, the global use of plastics (which reached 460 megatons in 2019) is on its way to tripling by 2060 and that perspective makes its impact an issue to take into account. However, media interest is obscuring the fact that a good number of studies are being launched to make statements without a methodological solidity behind them to sustain them. What really is the problem? In reality there are many problems. To begin with, the very term ‘microplastics’ is deliberately broad and confusing: we are talking about a myriad of things (fragments, fibers, films or particles) of numerous sizes and compositions. Its use is useful to be able to speak globally about the problem, yes; worse, it is generating in the population the idea of ​​”colored confetti” sneaking through the organs of animals and plants. Then came everything else. This is possible because this “everything else” has an explanation that is as simple as it is worrying. As Sergio Ferrer emphasized“the detection of plastics at these size scales is an extremely complex analytical process and the urgency to publish information about their presence in remote places (even in the human body) can favor the appearance of these high-profile publications.” In other words, the problem is another. As Hannah Arendt said, we often do not know how to distinguish between a refuge and a trap. The (almost hysterical) concern about microplastics, the tendency to legislate in a hurry in response to the social mood and the lack of rigor of the media (problem in which it is inevitable that we include ourselves) have turned this topic into a trap. Because, as I say, everything seems to indicate that (even though we don’t have a teaspoon of them in our brains) microplastics are a problem. All that remains is for us to accept the type of problem they really are, not to overreact and to take action on the matter.

We have been obsessed with Japan for decades to understand people who live over 100 years. The key was in Brazil

by

For decades, when science was searching for secrets of aginghe always looked in the same places: Japan’s “Blue Zones”Sardinia or the icy and homogeneous populations of northern Europe. However, researchers have pointed out that all this time we have been ignoring a biological gold mine: Brazil. The study. Understanding why there are people who live to be over one hundred years of age is undoubtedly an objective of science to to be able to unlock possible therapies in the future that will extend our lives much longer. Since it is curious that in specific areas such as Japan the population ages far beyond the normal average, being a mystery to science (although the reasons are already gone). The latest research on the matterpublished on January 6 in Genomic Psychiatry, has identified a genetic mix in the South American country that could contain protective variants invisible in more uniform populations. The Brazilian superhumans. The study, led by geneticists Mayana Zats and Mateus Vidigal de Castro, is based on the analysis of a group of more than 160 centenarians and at least 20 supercentenarians, who They are those people who are over 110 years old. Among these people, some quite relevant figures stand out, such as Sister Inah, who reached the age of 116, and several of the oldest men in the world, according to the LongeviQuest Atlas. But what really makes this group of people who have been analyzed by researchers special is not their age, but their biological resilience. Its biological resistance. The researchers’ main thesis is that the intense Brazilian miscegenation, fruit of centuries of interaction between indigenous populationsPortuguese colonizers, enslaved people of African origin and European and Japanese immigrants, has created a unique genomic diversity. By analyzing this genetic “breeding ground”, scientists have identified millions of variants that do not appear in large international biobanks. The hypothesis suggests that this mixture allows protective variants to emerge that are practically invisible in homogeneous populations. It is, in essence, a search for the genes of resilience in an environment of maximum diversity. COVID resistance. Without a doubt, it is one of the most fascinating examples of this history, since before the arrival of vaccines, three supercentenarians of the study they managed to survive the disease. By analyzing their immune response, the researchers found a concentration of cells related to innate defense that was very efficient. In this way, it was seen that individuals not only live longer, but also have a defense system capable of neutralizing threats that are lethal to people decades younger. Something that seems to be related to an increase in biological processes related to autophagy, that is, the ability of some cells to literally clean the body of harmful components. What was already known. This paradigm shift connects with previous works such as those done by researcher Manel Esteller on the epigenetic profile of the Spanish María Branyasthe oldest Spanish person of all time. In this case, what was done was to understand the “biological clock” of longevity in Europe. Now, the Brazilian project expands the map into the unknown. By sequencing entire genomes in this mixed-race population, scientists have discovered some eight billion undescribed variants, many of which could have a functional impact on how we age and how our cells withstand the test of time. Towards the future. The study of Brazilian supercentenarians is not only a matter of biographical curiosity about who holds the age record, but a critical step towards genomic medicine of the future. By understanding how the mixture of ancestors can concentrate protective factors against degenerative or infectious diseases, science is getting closer to discovering whether there is a biological “formula” for longevity that can be translated into therapies for the rest of the population. Brazil, with its genetic mosaic, is demonstrating that the most complex answers to our survival could be written in the genes of those who, against all odds, have seen more than a century of history pass by.

There are people obsessed with doing a post-Christmas “detox” based on juices. Your body has something to say about it

by

In the era of scroll infinite, the TikTok algorithm seems to have found the potion of eternal youth in 250 milliliter format. One day is the water with lemonother apple cider vinegar and, more recently, the beet shots either beet shots. Under labels like #detox or #guthealth, influencers with millions of followers promise to “cleanse” the body, flatten belly and speed up metabolism with a simple morning gesture. However, behind the careful aesthetics and pseudoscientific jargon, the medicine is forceful: your body is not a room that needs a three-day “cleaning spree”, but a complex system that already knows how to take care of itself if we do not hinder it. The viralization of deception. Behind the fascination with miracle cures operates a multi-billion dollar industry that capitalizes on consumer vulnerability. after the excesses, according to a report in The Washington Post. However, the phenomenon transcends conventional marketing to establish itself on social networks with alarming data: an analysis of Eating Behaviors Magazine on content on TikTok revealed that 97% of videos promoting supplements and dietary products lack any scientific basis. “Microbiota“. This gap between digital popularity and medical evidence evidences a public health problem where misinformation is monetized on a large scale. According to this same study93.6% of content creators do not mention their credentials, and the vast majority of promotions (95.7%) do not even clarify whether they are sponsored by brands. We are literally entrusting our metabolic health to strangers who they use terms as “microbiota” or “low-grade inflammation” to construct an illusion of rigor that sells much more than the boring reality of eating whole vegetables. The “detox” myth. Why do we feel “better” after a juice program? According to expertsit is not because of the mystical properties of celery or cayenne, but because we have stopped consuming ultra-processed foods, added sugars and alcohol for a few days. However, the concept of “detoxifying” the body with fluids is, biologically, nonsense. Dr. Tinsay Woreta maintains that the human body It operates with a highly efficient natural filtration system, where lungs, intestines and kidneys constantly eliminate toxins and pathogens. In tune, Mayo Clinic highlights the lack of scientific evidence on the alleged accumulation of waste requiring external “washing”; On the contrary, the institution warns that extreme cleansing, such as colon cleansing, poses an unnecessary danger that can lead to dehydration, infections or even rectal perforations. What science says (and TikTok remains silent). Far from being harmless, these diets can be counterproductive. According to a study from Northwestern Universityeliminating fiber to consume only juices—even for just three days—drastically alters the oral and fecal microbiome, increasing bacteria linked to inflammation and cognitive decline. Fiber is food for “good” bacteria that produce anti-inflammatory compounds; Without it, sugar-loving bacteria multiply. Even the “king” of home remedies, apple cider vinegar, has fallen from its pedestal. The famous study that supported its benefits for losing weight was retracted due to inconsistencies in the data and statistical errors. The reality is that taking it on an empty stomach can irritate the esophagus and permanently damage the enamel of your teeth. What is the real alternative? If the goal is longevity and liver health, science proposes replacing the “shot” with sustainable habits: Fruit is eaten, not drunk: Longevity expert Peter Diamandis a vital advice: If you like oranges, eat them whole. By juicing, you destroy fiber, which worsens satiety and triggers sugar absorption. Look North: As we obsess over supplements, the “new Nordic diet” is winning the battle to the Mediterranean in some studies. This pattern (based on canola oil, whole grains like rye, and berries) reduces the risk of fatty liver by a staggering 58%. Strength versus fragility: Walking is great for the heart, but to age with autonomythe body needs weights or elastic bands. Strength exercise is the only way to stop sarcopenia (muscle loss) and release myokines, proteins that protect the brain against Alzheimer’s. Be careful with him Protein Chic: The trend of adding protein to everything (coffees, yogurts, bars) is often an unnecessary expense. Dr. Stuart Phillips points out that excess protein It doesn’t build muscle on its own—training does that—and can unnecessarily strain the kidneys and liver. Health has no shortcuts. In short, science suggests that the best “cleanse” is one that is not done intermittently. As the experts consulted by The Washington Post concludea week-long juicing regimen cannot undo the damage of a sedentary lifestyle or a regular poor diet. The next time you watch a video with a magenta liquid promising miracles, remember: your liver is already working at full capacity while you sleep. What he really needs is not a trendy juice, but rather that you give him three days of weekly alcohol rest, a diet rich in fiber and, perhaps, that you stop searching on your cell phone for what can only be found in the market and in the gym.

We have been obsessed with the Mediterranean diet for decades. Turns out the Nordics had a much better solution

by

If we go back to 2009, many of us will remember a program known as The Deadliest Warrior (Deadliest Warrior). The premise was to pit two combatants from different eras against each other to see who would win in a duel to the death. Although on the screen we saw the Viking measure his axes against a Samurai, and the Gladiator against an Apache, we never got to see the direct duel between the colossus of the north and the warrior of the Mediterranean. That “fight of the century” was left hanging on television, but in the field of nutrition, the Roman side (the Mediterranean diet) has been the undefeated champion for decades. However, science has decided to simulate that combat in the laboratory in 2025, and this time the Viking’s ax has nipped Mediterranean leadership in the bud. According to the latest studies, the Nordics have a much better solution. A new discovery. Given that we live in the Mediterranean area, it seems impossible to do without olive oil and wheat. But, as nutritionist Dawn Jackson Blatner explains in National Geographica “cousin to the Mediterranean diet in colder climates” has emerged that is demonstrating surprising results. Originally created in 2004 by a committee of scientists and chefs—under the premise that health is not incompatible with gastronomic pleasure—the “new nordic diet” It does not seek longevity, but rather does so with a focus on local sustainability that the Mediterranean model often ignores outside its borders. The most recent milestone is the study published in Frontiers in Endocrinology. After analyzing a young and middle-aged population, researchers led by Abdelgawwad El-Sehrawy found that those who strictly follow the Baltic Sea dietary pattern have a 42% lower risk of developing type 2 diabetes. If the strictest adherence index is used, protection rises to a staggering 52%. This finding is crucial because it shows that the benefits act as a preventive shield from youth, and not only in old age. A shield against modern diseases. The robustness of this diet is supported by an “artillery” of previous research that already pointed in this direction. As a 2024 study details published in Scientific Reportsthe Nordic diet is one of the best tools to combat non-alcoholic fatty liver, reducing its risk by 58%. Added to this is that the benefits do not remain in the metabolism. According to a 2022 meta-analysis published in Diabetology analyzed data from more than a million people, confirming that those who follow this lifestyle have a 26% lower risk of dying from cardiovascular disease, a 22% lower risk of premature death from any cause, and a 14% lower chance of dying from cancer. As Dr. David L. Katz states“all good diets are made up of real foods, mostly plants; the Nordic diet is a masterful variation on that same theme.” What does it mean to eat like a Nordic? Many will surely have thought that it would be something like “eating aranques every day”, but (happily) it is not like that. The mainstay is canola (rapeseed) oil, rich in omega-3 fatty acids and more affordable than olive oil, along with: Whole grains: Rye, barley and oats (essential due to their low glycemic index). Forest fruits: Blueberries, raspberries and wild berries. Tubers and cruciferous vegetables: Beets, carrots, cauliflower and cabbage. Fatty fish: Salmon, mackerel and herring. Fermented dairy: Like skyr or kefir. Beyond diet. One of the points to highlight about the diet is that, according to research by British Journal of Nutrition, Women who followed the Nordic diet reached old age with significantly greater physical performance, easily passing walking and strength tests. The Nordic diet has an ‘inevitable’ side effect: weight loss. And it does this by hacking the feeling of hunger. The NORDIET study put to the test to subjects with high cholesterol and the result was a drop in weight and blood pressure without the stress of measuring each gram. But the most compelling data came from the NND trial. in The American Journal of Clinical Nutrition: Participants with abdominal obesity lost an average of 4.7 kg by eating on demand, without quantity restrictions. Compared to the few kilos lost by those who followed a normal diet, the Nordic system appears to be much more efficient. A solution for everyone. What the north teaches us is that health is not the exclusive property of one geography. As dietician Joan Salge Blake points out,the success of this diet lies in its ability to add strength. It’s the mix of fiber, healthy oils and antioxidants that really matters, acting as a balm against inflammation. It is there, in that inflammation that fuels the diseases of our century, where the Nordic diet fights and wins its most important battle.” You don’t have to live in Oslo to benefit. The key, according to experts, is to prioritize whole foods, choose fatty fish (even if they are frozen or canned due to their affordability) and replace white bread with whole rye. The Nordics seem to have found the recipe for a long, strong and sustainable life. In 2025, the fight is over: the Viking knows how to take better care of himself.

The origin of December 25 is in an obscure third century antipope obsessed with the birth of Christ

by

For years, we have repeated that Christmas is an invention. Not only does the Bible not specify that Jesus was born on December 25, it is that It is implausible that it was on that date. The gospels themselves detail that there were shepherds tending flocks outdoors (something unlikely in the Decembers of the time in Bethlehem), but the idea that the Romans were going to take a census on those dates is almost delirious. For this reason, we have repeated over and over again, the most reasonable explanation is that during the 4th century, the Church set the birth of Christ on December 25 to make it coincide (and in the process ‘Christianize’) the pagan festivities of Sol Invictus and Saturnalia. The only problem is that the latest available evidence goes in another direction: that of an obscure third century antipope who, obsessed with making a chronology of the scriptures, arrived at the date of the 25th independently. This is the story of how Hippolytus of Rome invented Christmas. The myth of the Christianization of Roman festivals Hail, Caesar! Io, Saturnalia! by Lawrence Alma-Tadema But let’s start by reviewing the best-known theory and seeing why some authors They have started to doubt them. As is often read on the Internet, this theory tells us that there is nothing coincidental about the December 25 election. On that date there was already a birthday, that of the “Unconquered Sun” (which would be the winter solstice for the Romans) and the Church, which during the 4th century struggled to — and would succeed — to become the official religion of the Empire, would have taken advantage of the pull of the pagan festival to place Christmas there. And the theory makes sense. However, it has a big problem; does not really resolve the question at hand: why 25? As explained Thomas C. Schmidta researcher at Princeton University, indeed the Roman Saturnalia fell on those dates, but not on that date. Certainly, it is difficult to be conclusive when we talk about that historical period, but everything seems to indicate that the strong day of Saturnalia fell closer to the 17th than to the 25th. In fact, if this approximation is true, we could not even say that it is the end of the ‘sigilarias’ (the celebrations – of a week – that followed the birth of the Unconquered Sun). Other festivities such as the Kalends (which were already celebrated in January) or the brumals (the solstice festival) do not fit well with the date in question either. That is to say, the idea that these Roman festivals are the origin of Christmas is, as I say, suggestive; but it still does not provide a convincing explanation as to why the Church chose the 25th. To answer that question we have to dig a little deeper. Since when is Christmas celebrated in “Christmas”? As says Schmidt.the first historical reference to December 25 as the day of the “birth of Christ in Bethlehem of Judea” can be found within the Filócalo Calendarin a document dated 336. It is a curious fact. And, although it is not something that explains the central issue of our question (the reason for December 25), it does give us a time frame: it tells us where to look for that explanation because, for practical purposes, we can assume that during the 4th century the festival was already relatively consolidated. That is, you would have to search a little before. Specifically to 222. In that year it is dated a statue of Hippolytus from Rome found in 1551 near the Via Tiburtina. The interesting thing about the statue is that, among its many inscriptions, it includes a lunar tablet that is kept today in the Vatican Library. Who is Hippolytus of Rome and what does he have to do with all this? Adoration of the Shepherds, by Gerard van Honthorst Hippolytus of Rome is a very multifaceted figure. Considered one of the great theologians and preachers of his time (in fact, Origen can be considered his disciple in some respects), he led a schism in 217 that led him to distance himself from the Church for a decade. He is, at the same time, the first antipope in history and a saint who, according to what is said, died martyred 235: he is, in fact, the only antipope canonized to this day. Well, we know that already in 220 after Christ, Hippolytus (in a commentary on the book of Daniel) defended that “The first coming of our Lord, in Bethlehem, was on Wednesday, December 25.” However, we also know that this text is manipulated. There are several versions with modified dates: among them, some that explain that the birth was in March or April. And the truth is that if Jesus was born in April many of our problems would be solved suddenly. However, looking only at the texts, it is not clear. That’s where the statue comes in. Because in the lunar table of the inscriptions, all past and future Easters appear calculated and, along with them, two key notes for us: the original Good Friday (which fell on March 25) and the “genesis” of the Lord (the year 2 AD) which fell on April 2. In the year 235, in a very ambitious work in which he traced the complete chronology of creation, Hippolytus It advanced that origin to March 25 for the simple (and, seen from today, absurd) reason that that was the date on which, according to their data, the world had been created. The true “genesis” of Christmas Paolo de Matteis But what does all this have to do with December 25? The answer is in the statue although I have overlooked it: specifically, in the word “genesis.” Because what is the “genesis” of a person? His birth or his conception? While it would be better for us if it were his birth (because it would fit with what the Bible says about Christmas), … Read more
