Is it healthy to eat an ice cream each and every day of summer? Science already has an answer

by

In a balanced and varied diet it is not difficult to find a hole for occasional whim, a sweet dessert or a Snack from time to time. Now, finding balance is not always easy, even more so when we often receive news that they point out that foods like ice cream They are healthy, something that seems to contradict our most basic ideas about nutrition. So is this true? How often can I eat ice cream? First, bad news: no, eating ice cream is not especially healthy. As with the consumption of certain alcoholic beverages such as wine, the fact that some study finds positive properties in any of its converters, does not necessarily imply that a food will be healthy. Here it is important to address several issues issues. The first is that there may be other components that cancel the positive effect detected. In the example of wine, its alcohol content tends to counteract the impact of compounds such as polyphenols. A key question to ask ourselves here is if we can obtain the beneficial compounds of a source that does not contain the harmful compounds. It is also relevant to attend to what aspect of health a certain study refers. Analysis can be carried out focused on A specific aspect of healthsuch as the incidence of cardiovascular diseases, diabetes or cancer. It is therefore important to understand that what can be good for one aspect of our health may not be so much for another. Interpreting the results of a study is important, but sometimes the methodology can also give us important clues when making this interpretation. An example we have In an article for The conversation Written by Duane Melor, expert in Medicine and Nutrition of Birmingham Aston University. Although it is an interesting result, some factors must be taken into account, the first, the fact that ice cream represents a small element of the diet and that sometimes other variables can play a bad pass. Melor In a doctoral thesis published in 2018 and focused on the heart effects of dairy products. The thesis, the expert indicates, included a study in which it was observed that, among the study population (composed of people with type 2 diabetes), those who consumed ice cream no more than twice a week showed a 12% lower risk of suffering from cardiovascular diseases, compared to those who did not consume this sweet. Although it is an interesting result, some factors must be taken into account, the first, the fact that ice cream represents a small element of the diet and that sometimes other variables can play a bad pass. “It is important to note that this bond between ice cream and heart disease only becomes apparent when other aspects of people’s health are taken into account, including how healthily they ate,” MELLOR EXPLAIN IN YOUR ARTICLE. “This suggests that eating A generally healthy diet It is possibly more important when reducing the risk of cardiovascular disease in people with type 2 diabetes, compared to eating ice cream. ” Establishing causal relationships in observational studies such as this is difficult and mellor gives us an example of why. A person with problems prior to the study may decide to stop consuming ice cream to improve their diet. This implies that this person will be seen for the purpose of the study as a person with a worse level of health despite leading a seemingly healthier life. If there is a marked trend, that is, if there are numerous cases like this, the results of the study may present biases. Practice and theory Ice cream are usually high caloric food in sugar and in fat. This, as we point out at the beginning, can fit perfectly into a balanced diet, but it does not mean that a food is healthy. He sugar consumption It has been linked to very different problems that cover from oral health to an increased risk of cancer, also through diabetes. Fats and excess calories can also facilitate the appearance of overweight or obesity. While this is not a health problem in itself, it is a risk factor in the appearance of diseases and disorders, including cardiovascular diseases. There are also studies that point in this direction, some of them cited by Melor in their piece. A study Made by an Italian researchers team and published in 2019 in the magazine Nutrientsdetected that greater ice cream consumption was linked to the appearance Non -alcoholic fatty liver diseasesomething that is not exclusive to this food, but we must also take into account when making our nutritional decisions. We explained before something that we must take into account is whether we can find healthier alternatives. Part of The benefits that can give us ice cream come from milk, thanks to elements Like calcium either The probiotics. That is, non -sugary yogurt (or less sugary), cheese, or milk can give us some of these nutrients, turning them into alternatives that may perhaps fit more into a daily diet. So how much can I eat ice cream? There is no clear response, it depends on factors such as the type of ice cream we are consuming (the nutrients that each type of ice cream provides can vary) and the size of the ration, our diet and countless factors such as our weight or our state of health. If we wanted Consume ice cream every day We should make sure first to have A varied diet (and healthy lifestyle habits), consume reduced amounts and eliminate other added sources. And still nothing guarantees that this cannot lead to other problems such as the aforementioned fatty liver disease.

Aragon wanted his children to eat more fruit at school. So he went to look for her 10,000 kilometers away

by

The Aragonese political debate has waited these days with two unexpected protagonists: fruit and schools. Or rather, the fruit that is distributed in schools. Although Aragon has thousands and thousands of hectares full of fruit and vegetable trees and stands out in the production Of cherry, peach and apples, among other fruits, the farmers of the region have raised their voice to complain that in the educational centers of their villages, pieces that arrive from plantations located abroad are being distributed, in some cases thousands of kilometers. The complaint the has launched the union of farmers and ranchers of Aragon (UAGA) and puts the finger in a yaga that already has taken to the collective To the street. What happened? The complaint has been made public UAGA-COAG. In A statement Published yesterday the Agrarian Organization ensures that there are dining rooms of educational centers in Aragon in which fruit arrives from foreign countries is being distributed. Moreover, UAGA goes further and claims to have witnesses confirming that in several schools in the region oranges from Egypt and pears of South Africa have been delivered, cultivated to more than 10,000 kilometers of distance. As a test, the association includes a photograph in which a box of pears is shown that indicates that its origin is South Africa, although there is no reference that reveals that the image was taken in a Aragon school. Click on the image to go to Tweet. “Unfair competition”. In its statement UAGA claims to feel “outraged” by the importation of fruits that it is perfectly possible to find in the Spanish fields and questions that countries from which the merchandise is brought meet the sanitary, environmental and labor standards that the European Union does require that community farmers. “It involves the violation of the demands of the organization and the fruit growers that require the application of ‘mirror clauses’ to imports from third countries “, They emphasize From the collective. UAGA-COAG wields two reasons that, in their opinion, condemn local farmers to suffer “unfair competition” against imports from other countries. The first is the strict regulation imposed by Brussels to European plantations on the use of pesticides, manipulation and conservation of fruit. The second is labor costs. While in Spain they go up every year, in Egypt, complaintthe minimum wage is 176 euros per month and in South Africa it is around 270. Looking at the EU. The complaint of the UAGA has reached enough draft for the Aragon Government to have gone to give explanations. The regional press appointment Sources of the Ministry of Agriculture that clarify that the key is in the financing of the lunch and sowing program to schools: the funds start from the EU, with what they arrive accompanied by their standards. When hiring the fruit supply, a geographical proximity requirement is not applied nor is it requested that the products be of community origin precisely to avoid a “discriminatory competitive advantage” in the process. The regional government argues that its role is that of intermediary. And now what? The Regional Executive emphasize Also that the objective is to “consolidate healthy eating habits” among schoolchildren and that fruit and milk are distributed at times such as lunch and snack, not in dining services. The program is not exactly new, but now it is offered with mixed funds that combine a community contribution and another from Aragon. With the EU money, a lot of 300,000 euros that is managed with the requirements of Brussels is paid. With the one contributed by the Aragon government, another 200,000 is financed that can handle with its own criteria. And the administration already guarantees that, “in line with its defense of the local product,” will give priority to proximity productions. The idea is to distribute cherries, apricot and nectarines, although they can also be replaced by apples or pears if requested by the centers. Beyond schools. The fruit distribution program is important because it reaches hundreds of school points and thousands of children, but the “outrage” of Uaga-Coag is not explained only by the alleged distribution of pears of South Africa and oranges of Egypt instead of fruit grown in the Aragonese countryside. Farmers It has come out To the street On several occasions to claim decent prices, changes in community policy and greater controls to ensure that the merchandise that comes to the country conforms to the community demands with which they work. “These parameters make it possible to import fruit from third countries profitable for certain companies and generate unfair competition at all levels,” the Agrarian Association in Your statement. “To end these practices, UAGA insists on claiming public administrations (regional, state and European) the regulation of markets and the recovery of the principle of community preference.” Images | Federicoeth Photography (Flickr) and Uaga In Xataka | We have a hard time differentiating a banana from a banana.

We do not know if the AI ​​is going to eat your work, but the CEO of some startups are determined to convince you of it

by

AI comes for your work. It is the message that does not stop arriving since Chatgpt reached the market. And even before. The impact of artificial intelligence on the world of employment It can be hugebut for the moment They have not been noticed Its effects too much. That, they say more and more frequently the CEOs of technological companies, it will change. First, Shopify. Less than a month ago the CEO of Shopify, Tobi Lütke, He sent a memorandum To its employees with a clear directive: “Using AI effectively is now a fundamental expectation for everyone in Shopify.” In fact, he indicated that before expanding a workforce or investing in other tools, project managers should have exhausted all the ways to do that task with AI already available tools. Then Fiverr. The last to adopt a decision and speech of this type is Micha Kaufman, CEO of Fiverr, who in a memo to his employees emphasized the importance of protecting their careers in the face of the growing influence of AI. His message was overwhelming: “This is the unpleasant truth: AI comes for your work. Demons, it also comes for mine. This is a call of attention. It does not matter if you are a programmer, designer, product manager, data scientist, lawyer, customer service representative, seller or financial: the AI ​​comes for you. You must understand that what were previously considered” easy tasks “will no longer exist; what were considered” difficult tasks “will be” difficult tasks ” Easy, and what was considered “impossible tasks” will be the difficult thing. Finally (for the moment), Duolingo. Luis von Ahn, CEO of Duolingo, announced its template A few days ago his intention to be “an Ai-first. Among the measures that the company will take is to “gradually stop hiring freelancers to do the work of which AI can be commissioned.” Of course, Von Ahn apostilled, “Duolingo will continue to be a company that deeply cares about its employees. This does not replace the DUOS (company employees) with AI. It is about eliminating bottlenecks so we can do more with the spectacular duos we have now.” Many said it before, many will say it later. The message is explicit, but of course it is not new. The appearance of Chatgpt caused this type of predictions to become increasingly frequent, and little by little we have seen how the CEOs of large companies have talked about the impact that AI will cause on work. Above all, in the world of programming: Jensen Huang, CEO of Nvidia, was clear a year ago than No one should learn to programand they have also said Mark Garman (CEO of AWS) or Satya Nadella, CEO of Microsoft. Mark Zuckerberg joined that prediction a few days ago and assured that in 12-18 months the majority of the code would be written by an AI. And I didn’t talk about the machines autocomplete code, but that they would write it completely. First it will help us, then (perhaps) it will replace us. Many experts believe that AI It will enhance our productivity And it will help us do more And better work than ever. It is what happened with the computer or internet, but with AI there is a clear fear that I end up going beyond and completely doing our work. The possibility is there, although with other technological revolutions, there will be more threatened jobs and others that will be less. Bill Gates, for example, believes that Doctors and human teachers do not have much future And Sam Altman, CEO of OpenAI, states that the impact of AI on employment “It is a huge, huge problem“. Perhaps 140 years of history point to a surprising future profession. Hairdressers. Between 1871 and 2011 Technology created more jobs than destroyed. The 2015 study published In The Guardian It focused specifically on data from the Census of England and Wales, and that allowed to assess the impact of technology on the world of employment. The most physical works clearly fell into a fee, but while or other professions were created, or professionals were added to which there were already. For example, surprise: the number of hairdressers grew prodigiously throughout those 140 years: just 0.1% of the workforce in 1871, this group went on to represent 0.6% in 2011. But the impact is inevitable. There are more studies and forecasts that occurred before the current “revolution” of AI. In 2018 the World Economic Forum (WEF) He published his report ‘Future of Jobs 2018’. In their conclusions they pointed out that automation would eliminate 75 million jobs by 2025, but would create 133 million new functions. The balance has changed five years later. In your 2023 reportthis agency pointed out that in the next five years it is estimated that 83 million works will be lost and 69 million will be created. The funny thing is that lately workers They seem to be somewhat more optimistic With his future. Image | Fiat Chrysler Automobiles In Xataka | Thousands of employees use AI in their work. More and more do not want their bosses to discover it

We already know where the microplastics get the lettuce that you eat in the salad: from the air

by

At this point of 2025, the idea that everything (Absolutely everything) It is full of microplastics. Plants are no exception; nor, of course, the vegetables we consume. The matter is that, for a long time, we have assumed that these compounds entered them through roots, soil and water. It is not exactly like that. No? And where do they come from? Well, a few days ago a Chinese research group published in the magazine ‘Nature’ The first solid evidence that supports the idea that one of the main routes for these microplastics is air. And it is in a lot of environments: Tianjin scientists collected all kinds of leaves, herbs and vegetables of urban and rural environments. In all, they found plastic particles in the foliar fabric. In the most polluted sites, concentrations of up to 10,000 nanograms per gram of dry weight. Above all, polyethylene terephthalate (PET) and polystyrene (PS). And where do they enter? That is something that is yet to be confirmed, but everything seems to sign up for stomata (small openings formed by cells) and cutt it (a membrane covered by insoluble waxes, “Ideal for absorbing microplastics“). Once inside, the compounds move inside the plants using the vascular beam, are distributed by different tissues and accumulate in hair structures called ‘trichomes’, a kind of fitological ‘sinks’. A big problem … The Chinese study demonstrates that accumulated absorption and accumulation of atmospheric microplastics It is generalized. But there are keys that help us better understand the circulation of these compounds: for example, that the outdoor plants had between 10 and 100 times more pet than those grown in greenhouse. And that the efficiency of the absorption of the leaves is extremely low (around 0.05%); That is why this route has been discarded repeatedly. However, given the little evidence we have about how microplastics enter the soil and water, this route begins to take shape. And, we like it or not, right now it is very difficult to control. And, of course, even if we don’t know what they do … In our body, yes that data like these raised many doubts about what happens if we discover that (as we intuit) is a serious problem. Because, in short, Our control capacity It is extremely limited.

We have been asking us for years, we will eat in space. Now we know that at least miso

by

The space has become in recent years a more and more open place, not only reserved for a handful of trained professionals but also to anyone who can afford one of the nothing cheap passages that can lead one to cross the last border or even put it into orbit. Now, if we want to continue taking more and more people to space, solve The question of food It will be a key step. Miso in space. A group of researchers Miso has managed to ferment In a mission to the International Space Station (ISS), demonstrating that the food fermentation process is possible in environments like this. The experiment is a small step towards improving habitability conditions in space trips. From koji to miso. The miso It is a popular seasoning in Japanese cuisine. It is prepared from fermented soy, barley or rice grains, and salt. Soy fermentation is performed through a Koji fungus culture (Aspergillus oryzae), a fungus also used in the elaboration of the Sake. The team wanted to verify if this fermentation was possible in orbit, since microgravity conditions or cosmic radiation could affect the growth capacity of microbes in food. To check it, they sent a sample to low terrestrial orbit, to the ISS, For 30 days. As a control, they also fermented samples of the same lot on the mainland, at the MIT headquarters (Massachusetts Institute of Technology) and at the Technical University of Denmark. Fermantado. The experiment was successful. When the sample came to Earth, the team studied the state of microbial communities, aromatic compounds and sensitive properties. They detected, yes, some changes. “Fermentation (in the ISS) illustrates how a living system on the microbial scale can prosper through the diversity of its microbial community, emphasizing the potential of life to exist in space,” stood out in a press release Maggie Coblentz, who collided the study. Nuts. Trying things in a laboratory is usually a bad idea, but this time the team should also verify the taste of this space miso. They first verified that the orbital recipe contained the same aromatic compounds and amino acid profiles similar to terrestrial miso. Those who tested the space miso explained that the taste was good and similar to that associated with this product. They noticed that, a greater flavor of nuts and more toasted. The details of the study were published In an article In the magazine iscience. Expanding the menu. The experiment can be used to improve access to new flavors among people traveling to space. Today the foods that can be consumed in space are limited by factors such as the amount of water that we can lead to the space or product development requirements. The possibility of fermenting products in orbit will expand The limits What we can eat in space (e Even on other planets). And it is not only about the possibility of introducing new flavors: fermentation is a process that humanity has taken advantage of during millennia to preserve food and increase its useful life through transformation. Not so sterile. As Explain COBLENTZalthough we tend to see ISS as an aseptic and sterile environment, the experiment also demonstrates that microbial life is possible in these environments. This also implies bioethical issues about the fact that, if humanity ever becomes an interplanetary species, it will not do it alone but accompanied by both plants and infinity of microorganisms that can settle in these extraterrestrial environments.

If we want to eat less, eating more slowly is a valid strategy. In Japan they are investigating how to achieve it

by

Losing weight, or maintaining our weight under control is more than solving the simple calorie equation consumed against burned calories. Numerous more or less hidden factors can unbalance this balance, factors ranging from the metabolic to the sociological. The other factors. A Japanese researchers team He has investigated in how factors such as the number of bites, the rhythms we perceive in our environment and gender affect the duration of food. The goal is to eat more slowly to make us easier to have our weight under our control. Slowly. The idea of ​​stopping the rhythm with which we eat to eat less and be able to lose weight is not new but we can find it in guides and recommendations of More than a decade ago. It is not an infallible recipe, but According to expertsaid. The logic behind has to do with how the stomach and other organs of the digestive system transmit information to the brain and how it processes it. This occurs in two ways: first through nerve impulses, and then through the chemical signal that some hormones transmit. Replicating one of the hormonal signals that indicate that food has satiated us is precisely one of the mechanisms for which the consumption of Drugs like Ozempic makes us lose weight. An aid. Now, even when we talk about a “trick” like this, say it is easier than doing so. That is why the new study has analyzed how different factors affect the speed with which we swallow food. And in this, men and women have differentiated guidelines. “While the science of nutrition often deals with the metabolism and absorption of food, and dietary content, there are limited evidence in Japan that eating behavior connects both (points). This intrigue led me to study eating behavior, which involved gender differences,” pointed in a press release Katsumi Iizuka, co -author of the study. 33 participants. To put these ideas to the test, the team responsible for the study He put pizza portions to 33 participants, healthy adults between 20 and 65. They measured the number of bites and the times they already chewed what rhythm. They also used metronomes and headphones to induce more or less accelerated rhythms to check the response of the participants. As expected, the team observed important differences in the habits of men and women: on average these took longer to eat their portion (87 seconds in front of the 63 d them men). They also chewed more (107 times against 80 on average) and took more bites (more than double). Change the rhythm. However, gender was not the only factor that affected eating habit: rhythmic stimuli affected the time required to consume food. A 40 pulse tempo per minute (BPM) markedly elongated the duration of food compared to those who ate without rhythmic stimulation. The details of the study were published In an article In the magazine Nutrients. Facilitating work. Now, there are also reasons why being cautious when generalizing the results of the study. First, we must take into account the limited sample (33 participants). Second, also for the existence of cultural differences between our context and Japanese. These differences both to gastronomic culture and gender differences between men and women and the way in which each society expects to behave when they eat in public. Despite this, the results can help us design strategies to facilitate weight loss that best suits each person, taking into account, for example, their gender. The study can also allow us to know more about how changes in context can help us influence our eating behavior, such as using music with slow tempos to force more leisurely meals.

Elon Musk has revealed the formula of his team’s success. The problem is that they barely have time to sleep and eat

by

Facing The experiments and tests around the world that seek to establish a four -day workdaythe richest man on the planet proposes a hardly justifiable leap against. Elon Musk recently revealed which is the “formula of success” of the efficiency office it manages in the United States government. The keys: work So many hours that sleep deprivation threatens the health of the workers themselves. The culture of the extreme. He did it a few weeks ago through Your X account. Elon Musk revealed then that he and his department of government efficiety (Doge) work work nothing less than 120 hours per weeka figure that triples the standard day 40 hours. Musk argued that this titanic effort is what allows them to overcome their “bureaucratic opponents,” who operate with conventional schedules. What does science say to all this? Divide the day. Making the accounts more or less standard, and since a week has 168 hours, working 120 hours is to leave alone 48 hours for any other activityincluding in the eating equation, bathing, moving to work/return home and, of course, sleeping. In the best case, if an employee allocated those 48 hours only to sleep, he would get a maximum of 6.8 hours per night, well below The 8 recommended hours by health experts. However, it is still a utopia considering the time of displacement and any other of the basic needs, so it is likely that real rest is much lower. Science. In Fortune They collected several studies that warn about the serious consequences of working in excess. Mayo Clinic points out that sleep less than 7 hours At night it can contribute to obesity, diabetes, hypertension, heart disease, stroke and depression. WHO data already indicated in 2016 that 745,000 people died by cardiovascular diseases associated with working days of 55 hours or more. Microsueños. Since the 1950s, scientists Like William Dement They have documented The effects of sleep In the brain, identifying the IMPORTANCE OF REM DREAM and discovering the phenomenon of The so -called “microsueños”episodes of momentary unconsciousness that can cause fatal errors at work. More recently, studies have shown that lack of sleep reduces activity in The prefrontal cortex (responsible for decision making) and in The hippocampus (key in memory). The impact is not just neurological. The study of the World Health Organization indicated that working more than 55 hours per week increases by 35% the risk of stroke and in 17% the risk of heart disease. In terms of productivity, an investigation from Stanford University concluded that it falls dramatically After 50 hours a weekand that working 70 hours per week generates almost The same production as 56 hourswhich suggests decreasing yields beyond a certain point. Musk’s obsession. The truth is that it was already known that Musk was a recognized WORLKAHOLIC. In A 2022 interview With investor Ron Baron, he confessed to having lived three years within his factories in Tesla and Spacex, sleeping in sofastents on the roofs and even under his desk, surrounded by metallic dust and the most uncomfortable conditions. No doubt, his labor philosophy of “more hours is equal to more efficiency” has been widely criticizedsince scientific evidence suggests that imposing extreme days does not guarantee better results and, instead, It affects health and the well -being of workers. Govern without sleep. They counted in a VOX medium report that the extreme work rhythm in Doge has already generated serious mistakes In public administration. From multimillionaire mathematical failures to the accidental dissemination of classified information, fatigue seems to be affecting the capacity of the Musk team to make key decisions. The recent dismissal and Hurrying reaction of essential personnel in areas such as nuclear safety and Avian flu response It is a sign that the policy of exhaustion could be having real and dangerous consequences. Plus: Trump administration is implementing Mass dismissals in the IRS In full tax season, which could generate an administrative collapse. In short, these types of measures, promoted by an apparently exhausted team, arouse concerns about the efficacy and stability of the government Under this new hyperproductivity model. The failures of “hacking” the dream. Paradoxically, Musk and other technological leaders have recognized that The dream cannot be replaced. Companies like Eight Sleepthat sold rest capsules From no less than 4,600 dollars to Musk and his team, they reinforce the idea that, although the culture of extreme work remains promoted, they are also looking for more efficient ways to achieve that eight -hour standard. Even figures such as Mark Zuckerberg and Jeff Bezos have defended the Importance of rest In productivity. On the other sidewalk, while Musk insists on that exhausting routine, he himself has admitted that his ancient habits caused “brain pain”, in fact, his Erratic behavior in networks Social raises doubts about whether you are really improving your rest. Sleep more, no less. Despite the alleged glamor that some try to grant sleep deprivation, scientific evidence is overwhelming: The rest is indispensable For the optimal functioning of brain and body. Instead of glorifying days of 120 hours per week, the real challenge should be to find ways to maximize productivity without compromising health. One thing seems clearly clear: at the end of the day, not even the brightest and most innovative minds can escape human biology. Musk either.
