longevity

the macro study that supports a great longevity ‘hack’

by

Science and society in general do not cease in their attempt to achieve a formula to be able to extend life a little more, or at least reach have an older age with a better quality of life. In this sense, there are numerous articles that promise this type of improvement, although logically there is nothing miraculous here, but many different factors influence it. A new rule. A trick that has begun to have a presence among specialists In the world of healthcare it is the 5-2-½ rule. According to this premise, it is enough to sleep five more minutes, do two extra minutes of exercise and eat half a serving more of vegetables a day to mathematically gain an entire year of life expectancy. Its origin. This statement is supported by science, and specifically by a study recently published in The Lancet. The work in this case sought to answer a very specific question: what is the minimum change in our daily habits that achieves a measurable impact on longevity? To find out, the researchers did not take a dozen volunteers, but rather went to the UK Biobank, one of the most complete medical databases, to analyze a total of 59,078 participants with an average follow-up of 8.1 years. The analysis. With all these people they decided to measure sleep time, moderate to vigorous intensity physical activity, and diet quality using a dietary scoring system. The mathematics. By cross-referencing the data and applying statistical models, the scientists found a “minimum combination” that was statistically associated with adding a year to life expectancy. The exact numbers of the andstudio were: 5 more minutes of sleep a day. 1.9 more minutes of moderate-vigorous physical activity daily, which is rounded up to two minutes. 5 points of improvement in the dietary quality index, which is approximately equivalent to half an extra serving of vegetables per day. The small print. As with other similar studies, this is an observational study on a population whose lifestyle habits were studied. But it is not a trial that was 100% controlled, where one group was forced to sleep five more minutes and another not to sleep to compare what happened. And this takes a little weight off it. Furthermore, the “extra year of life” is a statistical model at the population level. This means that, if an entire society applied these slight changes, global life expectancy would increase in mathematical models. The problem is that at the individual level, biology is not that mathematical and that is why you cannot compensate for smoking or a severe genetic disease by eating half an extra tomato for dinner. Microhabits. Despite the nuances, the underlying message of the study is tremendously positive. Historically, public health messages have been overwhelming, advertising phrases such as “do 150 minutes of exercise a week”, “radically change your diet”, “get 8 hours of sleep without fail”. This study scientifically demonstrates the immense power of microhabits. It basically tells us that we don’t need to prepare for a marathon or embrace extreme diets for our body to notice it. Adding a handful of spinach to your meal, getting off the subway a stop earlier to walk for two minutes at a good pace, or going to bed a little earlier are actions with almost zero friction.

the protein that longevity laboratories want to inject in the future

by

In 1997, the Japanese doctor and researcher Makoto Kuro-o made a mistake in the laboratory where he carried out his experiments. I was trying to create mice with hypertension when the genetic material he manipulated was inserted in the wrong place and altered an unknown gene. The resulting mice aged at an astonishing rate: in just two months they had arteriosclerosis, osteoporosis, cognitive decline and wrinkled skin. The normal thing is for a mouse to live almost three years, but those animals would live much less. After four years of investigating what had gone wrong, Kuro-o identified the gene responsible and published his discovery in Nature. called him klotho in honor of Clotho, the Greek goddess who spins the thread of life. He had discovered, by accident, one of aging suppressants most powerful known. The protein klotho It exists in two versions. One is anchored to the membrane of kidney and brain cells. The other is a fragment that breaks off from the membrane, enters the bloodstream and travels throughout the body acting as a signal of systemic health. The problem is that its levels fall constantly with age in both humans and all primates that have been studied. The interesting thing is that this is not at all a biological coincidence: it is a mechanism that has direct consequences on our aging. A very powerful weapon against aging The most relevant experiment so far He published it in 2025 an international team of researchers from the Institute of Neurosciences of the Autonomous University of Barcelona led by Professor Miguel Chillón. These scientists treated mice with gene therapy in order to get their own cells to produce more klotho. At 24 months (equivalent to about seventy human years) the results were notable: the treated animals lived between 15 and 20% longer with better muscle mass, greater bone density, less fibrosis and better cognitive function. In the hippocampus, the area of ​​the brain where memory resides, the treatment stimulated the generation of new neurons. A 20% longer lifespan in mice is, in aging biology, an extraordinary result. Have klotho in blood is important because this protein acts on several of the most damaging processes derived from aging. In the kidney it regulates how the body manages phosphorus. In fact, without klotho Phosphorus accumulates and accelerates cellular deterioration. The biggest challenge is to find a way to transfer all this knowledge to human beings. And in the rest of the body it reduces oxidative stress, stops chronic inflammation, activates FOXO3A (one of the most studied longevity genes) and inhibits cellular senescence, which is the state in which aged cells stop functioning well but do not die and slowly poison the tissue around them. Be that as it may, the biggest challenge is to find a way to transfer all this knowledge to human beings. In mice, viral vectors were used, injected both into a vein and directly into the brain, a combination that carries significant risks in people. The alternative is administer protein directly as a drug, but finding a system that keeps it stable and delivers it effectively to its target organs (the kidney, brain, muscles and bones) remains an unsolved problem. Still, the longevity biotech industry has decided not to wait. The American startup Minicircle, in which Sam Altman and Peter Thiel have investedbegan a phase 1 clinical trial with 24 participants in October 2025 to test a gene therapy for klotho based on plasmids: DNA fragments that do not integrate into the chromosome and whose effects last approximately one year. This therapy is not approved by the FDA (Food and Drug Administration), so it operates through international clinics. However, the applications pursued by the industry go beyond aging in healthy people. Klotho Neurosciences has programs underway to combat Alzheimer’s, amyotrophic lateral sclerosis and cardiovascular diseases, with phase I and II trials planned between 2027 and 2028. BioVivaon the other hand, has identified improvements in cognitive tests in patients with dementia treated with a combined gene therapy of klotho and telomerase. and the company Avaí Bio works with modified encapsulated cells that overexpress the protein. He plans to have his first results ready for the Second Annual Klotho Conference in September 2026. We have clinical trials, there is private capital moving on a large scale, and there is an annual conference dedicated exclusively to this protein. Everything we have seen in this article looks very good, but we must not overlook that the solid life extension data comes from mice, and the history of the biology of aging is full of spectacular findings in animals that have not been transferred to humans with the same success. Furthermore, several important unanswered questions remain on the table: what effects does overexpression of klotho in the long term, whether the timing of its administration matters in both people and rodents or what happens to phosphorus metabolism and vitamin D after years of treatment. Still, for the first time we have clinical trials, there is private capital moving on a large scale, and there is an annual conference dedicated exclusively to this protein. Klotho is, ultimately, one of the most promising weapons that biology has put in our hands to deal with our aging.

We sensed that there were areas in Spain where longevity was greater. A map has just confirmed where the “Holy Land” is

by

The year before the new millennium entered, the Belgian demographer Michel Poulain arrived in a small town in Sardinia looking for a statistical error: too many male centenarians to be credible. What he found there would end up giving rise to the concept of the “Blue Zones”the regions of the world where living for more than a hundred years is not a rarity, but almost a custom. Now, the same researcher claims to have found something similar much closer: in Spain. The map that confirms an old intuition. For years there was a suspicion almost intuitive in Spain: there were territories where people not only lived longer, but also aged better. Now a map has made it black on white. The demographer Michel Poulainwho, as we said, is one of the world’s great experts in longevity and creator of the modern concept of the Blue Zoneshas applied its extreme longevity index to the Spanish territory and the result draws a very clear pattern: The north and part of the interior have a probability of reaching 100 years that is up to three times higher than that of the south. It is not a cultural perception or a family anecdote. It’s demographic statistics. Where is the Spanish corridor. The map pinpoints a species privileged belt. Navarra, La Rioja, Soria, Guadalajara and Segovia top the classification, followed by other areas of Castilla y León, Catalonia, Álava and a good part of the northwest of the peninsula. In it opposite end appear Seville, Cádiz and Málaga, where the possibility of reaching a centenary falls very noticeably. The big surprise is not only the gap, but its magnitude: tripling the odds within the same country, with the same health system and political framework, forces us to look beyond genetics. We no longer talk about “blue zones.” The finding also changes the way we study aging. For years the dominant model was that of the Blue Zonesthose iconic places like Sardinia, Okinawa or Icaria where centenarians accumulate. But Poulain believes that model has fallen short. Now science speaks of “longevity corridors”: large areas where the combination of social, environmental, health and cultural factors generates a favorable ecosystem for living longer and better. Spain, and especially its northern halfone of those European corridors begins to emerge. It’s not magic, it’s lifestyle. The key, researchers insistit is not in a miracle recipe or a hidden superfood. Eating meaningfully, moving naturally, sleeping well, avoiding chronic stress, maintaining strong family ties, living connected to nature, and having purpose in life appear again and again as common patterns. They are simple habits, but sustained for decades. And therein lies the real lesson: longevity is not manufactured at 70, it is built from childhood. That is why experts insist so much on prevention and early education. The invisible factor. There is more, since one of the elements that is most repeated in these territories is something that rarely appears in an analysis: the social network. It talks about having support, not feeling alone, maintaining family and community ties, in short, continuing to be useful to others. That human tissue seems to act like silent protection against physical and mental deterioration. In many of these provinces, especially rural ones, there continues to be a denser social structure than in large cities. And that could be as important as diet or exercise. The great warning. Last but not least, there is a clear warning. The researchers they warn that these corridors are not eternal. Changes in diet, sedentary lifestyle, accelerated urbanization, loss of community and social isolation are eroding precisely the factors that made them possible. In other words, healthy longevity can be lost in a single generation if the environment changes. That is why the great objective now is not to admire centenarians as a rarity, but to study how they have gotten there to replicate those conditions. Because the map not only tells where you live most. It also points out perhaps something more important: where a way of living that the rest of the country is losing is still preserved.

We obsess over giving up meat completely, but the science of longevity asks us for something much more pragmatic

by

The debate about whether we should consume more or less meat is often plagued by ideology, but when we stick strictly to science, the reality is that it is sensed that a reinforcement of vegetable protein It can give us a few more years of life. And it is not about completely eliminating foods of animal origin, but about doing nutritional mathematics to replace a small fraction of animal protein with vegetable protein. Great studies there is behind it to be able to reach this conclusion, one of the most compelling being the published in The BMJ in 2020which brought together 31 prospective studies and more than 715,000 participants. Here it was clearly seen that a increased intake of plant protein It was associated with lower mortality from all causes and, specifically, cardiovascular disease. Translated into percentages, every 3% increase in daily energy from plant protein was associated with a 5% lower risk of death from any cause. On the contrary, animal protein did not show a clear association (neither for nor against) with cardiovascular or cancer mortality at a global level. There is more. That same year, the magazine JAMA public data from the NIH-AARP prospective cohort, which followed more than 416,000 people. Their findings further refined the shot, as they pointed out that replacing only 3% of the energy of animal protein with plant protein was associated with 10% less total mortality. The protective effect was especially marked when this vegetable protein entered the diet to replace eggs and, above all, red meat. The only problem is that, although the claim has a solid scientific basis, the relationship has only been demonstrated through observational studies. That is, we are not facing unequivocal proof of causality. The reason Whether vegetable protein from soy or lentils extends life is something that is still quite debated. The most solid biological hypothesis does not defend that plant protein is a magical elixir, but rather that, by displacing animal sourcesseveral risk factors for stroke tend to decrease. This is what is known in nutrition as the “package” effect. By swapping a steak for a plate of legumes, not only are you changing the amino acids that are introduced into the body, but you are drastically reducing your intake of saturated fat, iron, sodium, and, if we’re talking about processed meat, pro-inflammatory compounds. In exchange, fiber, polyphenols and other bioactive compounds present in whole grains, seeds and legumes are introduced into the body and can reduce the overall carbiometabolic risk. The small print. One cannot generalize here, and these results do not suggest that all animal protein is a poison or that any plant product is automatically a ticket to immortality. The expected result depends largely on the specific food that we are substituting on our plate, since it does not have the same metabolic impact to replace a processed sausage as a natural yogurt, nor is it equally beneficial to change chicken for legumes than for an ultra-processed vegetable substitute full of refined flours. Age matters. The age It is a very relevant factor which science has shown through a study published in Nature that analyzed national protein supplies in 101 countries over 60 years. Here it has been seen that, although the greater availability of vegetable protein is associated with a longer life expectancy, in children under five years of age the relationship seems to be reversed, suggesting that animal protein may be essential for their development.

We have spent decades ignoring an organ because we believed it was useless. Now they have seen that it is crucial in our longevity

by

In the center of the chest, just behind the breastbone, hides a small gland that has been systematically ignored by medicine when it comes to adult health: the thymus. Textbooks have long taught that this organ is vital in childhood to develop the immune system, but that It subsequently atrophies and turns into fat when we grow. But its role in the long run It’s not as irrelevant as we thought.. A turnaround. The paradigm that we were all taught at school has taken a big turn through a publication in Nature that has shown that the health of the thymus in adulthood not only matters, but is a determining factor in predicting how long we will live, the state of our cardiovascular health and also how we will respond to cancer. How it has been seen. The premise of this interesting study lies in a simple observation about people who did not have a thymus because it had been removed and the increase in mortality from all causes compared to those who have a healthy thymus. From here, a research team wanted to understand the true impact of a “sleeping” organ through different CT scans to calculate the thymic health of different people. The system analyzed the images of numerous people, including data from the National Lung Screening Trialwhich had more than 25,000 patients. By crossing the status of the thymus with the medical history and longevity of each individual, the results were so overwhelming that the researchers themselves they confessed It was the first time they had seen such spectacular results, since no one expected such a small organ to have such a clinical impact. Reduces mortality. This study has intensively analyzed the function of this gland in large groups of adults to discover that maintaining good thymic health is directly associated with lower overall mortality. But surprisingly, the study links having a healthy thymus with a lower incidence of cardiovascular mortality In oncology. This is where the finding takes on a revolutionary clinical dimension, since the data show a clear correlation between a healthy thymus and a lower incidence of lung cancer. But we can go further by pointing out that patients who undergo immunotherapy and have a healthy thymus respond greatly to the treatment, and even have a lower risk of suffering from cancer again. Preventive medicine. With this evidence, “thymic health” is positioned to become a very important parameter in the field of personalized medicine to gain insight into how a patient may accept a treatment. But in addition, monitoring its degradation could allow medicine to anticipate autoimmune diseases in those people who already have a higher risk.

Science and longevity experts are clear about what time you should wake up

by

For years, the culture of effort and extreme productivity has sold us the “five o’clock club“like him Holy Grail of successtaking as examples to CEOs, influencers or personal development gurus who point out the need to wake up at five in the morning. However, science focused on aging has a very different message: waking up too early is not only not productive, but it can shave years off our life. The experts. Sebastian La Rosaa doctor specializing in longevity, already pointed out that the optimal time to wake up is in a very specific window: between 6:45 and 7:00 in the morning. And the reality is that the scientific literature supports its claims based on clinical experience quite well. Without going any further, an analysis that lasted for 20 years in large groups of people revealed that the lowest point of mortality risk is exactly around seven in the morning. From this point on, extremes (as often happens in biology) are quite expensive. The extremes. Get up constantly after 8 in the morning raises the risk of mortality from all causes by a staggering 39%. But being a night owl and waking up super early every day isn’t good for your health either. This is what they saw from the data extracted from the UK Biobankwith a sample of more than 433,000 people, showing that the evening chronotype (going to bed late and getting up late) has a 10% higher risk of mortality total compared to early risers, impacting more harshly on people over 63 years of age. More tests. On the other hand, a massive study from the University of Exeter found that people who wake up naturally between five and seven in the morning reduce their risk of premature mortality by between 20 and 25%. This fits perfectly with the recommendation to go to sleep between 10:00 p.m. and 11:00 p.m. to achieve 7 or 8 hours of restful sleep and protect, in the process, cardiovascular health. The golden rule. While 7:00 a.m. seems like the evolutionary magic hour, researchers at Harvard and other pioneering institutions have reached an even more important conclusion: consistency is the most important factor. In this way, having irregular sleep schedules, such as going to bed and getting up at very different times each day, increases the risk of mortality between 20 and 48%. In fact, the regularity of the sleep-wake cycle has been shown to be a stronger predictor of mortality than the total number of hours slept. This forces the scientific consensus to establish that sleeping between 6 and 8 hours is ideal, with exactly 7 hours being the figure linked to greater survival in large population cohorts. But if we choose to sleep less than seven hours or more than eight hours, the body can become unbalanced and increase the risk of death. Hacking the internal clock. Behind all these statistics there are pure cellular mechanics. In animal models, it has been proven that having “high amplitude” circadian rhythms, with very marked differences between daytime alertness and nighttime rest, directly correlates with greater longevity. When this biological clock is altered by living behind sunlight, we alter metabolic pathways critical for aging such as via mTOR, sirtuins or IGF-1. Exposing yourself to natural light as soon as you wake up around seven in the morning is the signal that the brain needs to set this complex hormonal mechanism in motion, mitigating oxidative damage and preventing cardiovascular diseases and cancer.

We believed that a vegetarian diet guaranteed longevity. In extreme old age, the data says just the opposite

by

There are many positions in nutrition about what food It is the one that will give us a better old age. One of the positions that you have surely heard is the need to reduce meat consumption to prioritize vegetables for everyone the benefits that they contribute. But now science is pointing out that what works at age 40 may not be ideal at age 90. The change of course. A published study this same year in The American Journal of Clinical Nutrition has shaken the hornet’s nest of gerontology after analyzing thousands of elderly people. The conclusion they have drawn is that among those over 80 years of age, those who consume meat are more likely to become centenarians than strict vegetarians. But before you rush to cancel your salad order, read the fine print: the key is not the meat per sebut weight, fragility and the fight against muscle loss. The data. In order to reach this conclusion, the study analyzed data from a longevity survey in the Chinese population carried out between 1998 and 2018. In total, the researchers followed 5,203 participants who were over 80 years old, classifying them based on omnivores or vegetariansincluding vegans and ovolactovegetarians. The results. Adjusting for age, gender, and baseline health, the study yielded a surprising finding: vegetarian diets were associated with a 25% lower chance of reaching age 100 compared to omnivorous diets. A correlation that was statistically significant mainly in the elderly who were already thin. Thinness. This is a really important point to present one of the nuances of this research. And the advantage of carnivores disappears in people who have a weight within the established normality. Thus, the negative association between being vegetarian and extreme longevity was observed almost exclusively in participants with a BMI lower than 18.5. That is, extreme thinness. This reinforces what is sometimes known in medicine as the “paradox of obesity in old age“. While in youth overweight is a risk factor for almost everything, in extreme old age, having energy reserves and muscle mass is life insurance. This is why the authors of the study emphasize that the consumption of foods of animal origin seems to act as a protective factor against malnutrition and frailty in these vulnerable individuals. Because. The biological explanation that suggests that meat is good in old age is based on the constant fight against degradation. One of these events is the dreaded sarcopeniawhich occurs when the natural loss of muscle mass accelerates over time. One of the objectives here, as we have repeated many times, is to maintain muscle with highly bioavailable proteins that are in meat, eggs and milk. In addition to this, the study suggests that strict vegetarians, especially thin ones, may not be ingesting enough total calories to maintain their physiology in stressful situations. And it is not crazy now, but previous studies have already pointed out that, although restricting meat reduces mortality in young people and middle adults, this effect was reversed in old age. They don’t cast a shadow. Logically, this study does not negate the many benefits of a plant-based diet for the general population. In fact, there are studies that suggest that for the vast majority of the population the priority continues to be preventing serious chronic diseases such as diabetes. However, this work suggests that nutrition must be dynamic, since the requirement in middle age is not the same as in the last years of life.

It turns out that a longevity expert has said something that makes sense. And the reason is the juices

by

Peter Diamandis has returned. The famous doctor and engineer specializing in longevity has once again made simple dietary advice viral: “if you like oranges, eat them whole and not in juice.” And, to the surprise of all of us who closely follow the worldit’s a good idea. Beyond the joke, longevity is becoming serious. Very serious indeed. Since an open microphone confirmed to us in September that longevity is becoming a crucial issue for oligarchs of the present, it is impossible not to look at this community of researchers, influencers and entrepreneurs in a “different way”. However, the reality is obvious: most advice on how to live longer is a mix of cherry picking, scientific sensationalism and common sense. Ultimately, to the extent that society is increasingly obsessed with living longerthe ‘market’ for these types of ideas is growing (for better and worse). And Diamandis is a good example. As They explained in El Confidencialthis entrepreneur and researcher has a very long list of dietary ideas: from withdrawing dairy products due to the body’s inflammatory response to casein to avoiding red meat due to its saturated fats (basing his diet almost exclusively on vegetables and whole foods). As we saw a few days ago with other well-meaning advicethese kinds of ideas make some sense, yes. However, every heuristic has two sides: it illuminates a certain part of reality and helps us manage it more easily. But it hides other parts and makes it seriously difficult to be aware of them. But, let’s get to the juices. Because that is the latest advice that has been vitalized is precisely that: that the debate has never been “yes fruit” or “no fruit.” ¡Of course you have to consume fruit! The debate is how we consume it and in juice it is, possibly, the worst way. By squeezing the pieces of fruit, we not only reduce the fiber but we end up consuming something completely different: satiety is worse and sugar absorption is improved. When we talk about fruit being good, what we are saying is that we need the fiber it contains for its metabolic and satiety effects. Oh really? So much so that organizations like the AESAN they insist repeatedly that juice does not replace whole fruit. And yes, I know that for many it is a commonplace (and something very well known), but it never hurts to repeat it: the consumption of rooting fruit has fallen 14% in recent years. We already know that it is good advice, but also worse for longevity. Here, the truth is that the evidence is less clear. Above all, because it is never enough to ‘stop recommending something’, we must go further and put better options on the table. And yes, water is always an option. But unfortunately, it is not always a substitute for the social consumption of juices.

how much science believes our longevity will actually increase

by

Society is increasingly obsessed with living longer and longer and have an aesthetic that corresponds to a younger age. Right now there are many really eloquent projects to achieve practically immortalitybut this makes us wonder if our body has some kind of limit that cannot be exceeded. This is what science tries to elucidate. Nowadays, people who live more than one hundred years are something extraordinary, and we even see their centenary birthdays appear on the pages of the newspaper or on local television programs. But the question in this case is whether the new normal will be being able to live more than a century as something normal, and above all in good conditions. But the truth is that we are far from achieving this. Two concepts. The first thing to understand here is the difference that exists between the average life expectancy and maximum longevity. The first of these is growing spectacularly in the last century thanks to vaccines, hygiene, medications and better access to healthcare (although this reaches an older population, with its problems). But when we talk about maximum longevity we cannot say the same, since it is a much harder ceiling to crack. The obligatory question in this case is clear: where is our ceiling that we cannot break? Less than expected. There is now solid scientific evidence that suggests that human beings have a “factory” biological limit. Different studies, such as those published in Nature, they placed the natural human limit around 115 years. Although more recent and optimistic reviews, based on statistical modeling of the “supercentenarians” (people over 110 years old), extend that range up to 125 years. Therefore, we are not facing a scenario of immortality, but rather the age progression curve begins to stabilize at a specific point. And this is clearly a brake that biology itself is imposing on us, because our body has a very clear limit in its functioning. Prioritize well-being. Reaching the age of 120, but with very poor health, with many illnesses behind you or without being able to move, is not something at all attractive. That is why demographic projections for Europe They suggest that, by the year 2065, life expectancy will be between 87 and 93 years. This doesn’t sound like science fiction, and that’s precisely why it’s relevant. It is not about making quantum leaps through unproven gene therapies, but about the accumulation of medical and social improvements. The goal of modern longevity medicine is not for you to live 150 years connected to a machine, but to extend the “healthspan“, that is, the period of healthy life. We already know the ‘secret’. While we wait for drugs that reverse old age, science tells us that we already have the “technology” to maximize our lives and it has been used for decades in the so-called ‘Blue Zones’ of Okinawa as a standard. And it is precisely in this area that people It is capable of easily reaching 100 years without much problemand the question was obligatory: why here? We found the answer in studies carried out in this areait can be seen that the factors that influence being able to reach 100 years of life have nothing to do with transfusions of young plasma, blood cleansing or super-expensive therapies that promise miraculous results. Among the habits that follow we can find the following: Natural calorie restriction: They consume 10-15% fewer calories than an average Western adult. And we already know that this influences above all the generation of oxidative stress which is a great ‘poison’ for our body. The good carbohydrate diet: their diet is based on vegetables and complex carbohydrates such as sweet potatoes, with a very low animal protein intake. Youth biomarkers: the combination of diet and constant physical activity results in a lower incidence of chronic diseases. Less stress: another great poison for the body due to its involvement in cortisol levels. In Okinawa, community cohesion acts as a buffer for stress. The importance of habits. In this way, the scientific horizon for the next century does not promise immortality. It is likely that we will continue to see a trickle of individual records and exceptional cases of genetics that cause us to see people who far exceed the century of life. But for most humans, This is not something we get. (or at least with a good quality of life). The true longevity revolution in the 21st century will be to make reaching age 90 the norm and not the exception, applying what we already know works: moving, eating less (and better) and maintaining strong social ties. And above all, do not wait for a magic pill, as has been demonstrated by the habits of Japanese people who have achieved an effect that no gene therapy has achieved so far.

We have been intrigued by the “blue areas” in which longevity shoots. His secret may be in Finland

by

Scientists have observed for year “Blue Areas” With a mixture of fascination, suspicion And a pressing question: are there places that people usually enjoy longer and healthier lives? Is it easier to meet centenary people in certain regions From the planet, like Okinawa (Japan), Ikara (Greece) or Sardinia? And if so, why? A group of Finnish researchers believe they have found A new candidate To “Blue Zone” to the west of your country, a finding that can help us better understand these mysterious areas. For now, they have already managed to generate expectation. What happened? Some time ago a group of researchers from the Åbo Akademia University based in Turku (Finland), a peculiar objective was proposed: finding out if a part of its country fits the characteristics of what is usually known as ‘blue areas’geographical areas that stand out for the high longevity and healthy life habits of its inhabitants, two realities that experts believe they are directly related. To be more precise Nordic scientists focused on a handful of territories of the old Western Finland: The Swedish majority region of Ostrobotnia, South Ostrobotnia and the Åland islands. As explained in The article In which they have reflected their conclusions, their idea was to analyze the longevity indicators and then find out if the best results corresponded to the cities in which people enjoy a healthier lifestyle. But … What is “blue zone”? Regions in which people (apparently) enjoy longer and more healthy lives than normal. It is not a new concept. Its origins can be traced At least until 2004when the magazine Experimental Gerontology public A broad study on the centenary population of Sardinia, Italy. In it the authors marked with that color (blue) the regions of the map in which the longevity data were higher. In addition to identifying them geographically, researchers speculated that these indicators could be explained by factors such as nutrition, lifestyle or the proliferation of genetic characteristics that favored the locals. The fact is that the ‘blue areas’ liked and shortly after, in 2005, a journalist from National Geographic He used it in Another article in which he talked about three regions of the planet where on average the population enjoyed longer and healthy lives: Okinawa, in Japan, Loma Linda, in California, and Sardinia. The text was affected in the same idea: the phenomenon connects with certain healthy habits in these territories, such as nutritional diets, physical activity, stress control and moderate alcohol consumption, among others. And what did they find out in Finland? Åbo researchers identified a series of curious phenomena who, in summary, have taken them to conclude That the Swedish region of Ostrobotnia “could be a blue zone”, with a population characterized by its high life expectancy, health and positive life habits. However, that’s just one of your conclusions. And maybe not the most interesting. To understand it it is necessary to know Your study and the figures on which it supports. What figures? The most interesting are longevity. According to The data collected in Journal of Aging Research In the åland islands life expectancy among babies who came to the world between 2020 and 2022 was 83.5 years, in ostrobotnia of 83.1 and in southern ostrobotnia of 81.8. Any of these data exceeds both the mean of Finland (81.6) and EU’swhich is around 81.5. Worldwide, life expectancy at birth in 2022 was 72.6 years and, According to statistathat global average will not approach that of Ostrobotnia until the end of the century. Of course, it is a global average. In Spain the data is already Very simulate. And what does that tell us? The Åbo team did not limit himself to studying longevity records. After all, the blue areas have not been analyzed only according to demographic data. Experts also take into account factors such as “lifestyle and health”, which includes social relationships, diet, physical activity or even vital purposes. By taking into account these parameters, experts reached a conclusion: the relationship between them (longevity and the characteristics of blue areas) are not as evident as one would expect. What does it mean? That the greatest longevity data are not necessarily in the regions that best fit the ideal characteristics of a “blue zone”. It sounds confusing, but it is better understood with an example. The longest study of the study was Åland, an area that effectively presents good health data, but is “diverted from several principles” of what could be considered the ideal lifestyle. In part of Ostrobotnia something different happens: the healthy lifestyle is well implanted and yet its life expectancy is less than in other areas. What is the conclusion? There are several. To begin the researchers concluded that, if the age, health and implementation of the lifestyle of the blue areas, the Swedish Obstrobotnia are taken into account It could be considered Perfectly one of those redoubts that stand out for their longevity. Just like Other regions of the planet, such as Okinawa, Ikara or Oglybasra. However, research throws another more interesting reading, especially in the face of future studies on blue areas: when analyzing them it is important to take into account the context. “The possible coherence between longevity, health and lifestyle I could vary in different cultural, political, social and economic contexts,” indicates the articlewhich acknowledges that their data shows that “the Nordic regions with greater longevity are not necessarily adhere to the lifestyle of blue areas.” In other words, they insist: “The important lifestyle principles for longevity can vary in different regions.” Why is it interesting? Because beyond the implications it may have for Western Finland, its authorities, doctors and demographers, research throws new data and keys to the study of blue areas, a concept that in recent years has aroused two feelings: fascination … and skepticism. Since National Geographic public Your article The concept has generated debate and suspicion of those who warn that their scientific base results Little solid. In 2019 Dr. Saul J. Newman launched An article in which … Read more
