China has discovered a new mineral on the Moon. It’s so fluorescent it could change the way we make LED light bulbs

by

So far, 11 unique minerals have been discovered on the Moon. The last of them has just been revealed by a team of Chinese scientists after analyzing a lunar meteorite. It is an interesting finding, because it gives us useful information about the geology of our satellite. But also because it could have very interesting applications here on Earth. From the Moon to your light bulbs. The material just described It is cerium-magnesium changesite. It is characterized by its glassy, ​​transparent and brittle appearance. The thickness of its granules ranges from 3 to 25 micrometers, less than that of a human hair. Still, it is extremely useful due to its pronounced fluorescence, which could be very useful in improving terrestrial LED technology. A necessary color change. Unlike traditional incandescent bulbs, LED bulbs do not use heat to produce light. They make the most of electricity thanks to a semiconductor material, which allows the flow of electrons from a layer with an excess charge to another with a lack of it. That second layer has what are known as voids. That is, atoms that have lost electrons, leaving something like a free hole. The moment an electron encounters one of these holes, falls inside, in a process in which energy is released in the form of light. The light obtained in this process is blue, but we have all seen that, in general, the light from LEDs is white. The color change is achieved thanks to the coating the bluish chip in which the process occurs with a fluorescent material. This absorbs some of the blue light and, in turn, emits yellow light. Both are what are known as complementary colors of light. Therefore, when you mix them you obtain white light. The more fluorescence, the better. The fluorescence of this lunar mineral is so powerful that it would be a wonderful complement to LED bulbs. White light would be obtained in a much more efficient way, resulting in even greater energy savings. More achievements for China. The Asian country has become an expert in lunar geology, thanks to the Chang’e missions. In fact, the Changesite-(Y) phosphate was already discovered on Chang’e-5, directly related to this other mineral that a meteorite brought to Earth. For now, we can only dream. Logically, going to the Moon to excavate minerals is not very viable. And if it were, it would be good to think twice before jumping in headfirst. We also don’t know if there would be enough on the Moon. It would be necessary to explore it further to know. Therefore, the applications of lunar minerals in terrestrial technology are nothing more than hypotheses. It is interesting, but it does not have a close application in time. What these minerals do teach us. Analysis of lunar geology It can teach us many things. If we find mostly minerals that also exist here on Earth, we can understand that, at some point, similar conditions existed on Earth and the Moon. On the other hand, if many unknown minerals are found on Earth, as is already happening, it is understood that there were conditions on our satellite that have not occurred on our planet. All this serves to understand very well where we are and where we come from. Let’s stay with that instead of thinking about mining our satellite and leaving it without resources as we are already beginning to do on Earth.

Madrid has the key mineral underground so that Europe does not depend on China. The problem is that there is a gap above

by

Under the soil of Madrid lies a strategic resource that Europe desperately needs to reduce its technological dependence on China. To ensure this supply, the regional government has decided to make a move and protect the future of the Tolsadeco mine. The plan. As they progress in Europe Pressthe Community of Madrid finalizes the procedures to extend until 2037 the mining concession located between the districts of Vicálvaro and San Blas-Canillejas. It is about reactivating an open-air exploitation that has been paralyzed since 2007, with the aim of not losing access to the last reserves of a material critical for the industrial autonomy of the continent. A simple absorber or the future of the electric car? Although it is traditionally known for its domestic use as an absorbent material—especially in pet litter—sepiolite is today a very high-tech mineral. According to Europa Press citing the Elcano Royal InstituteSpain is the only European producer of this material, placing it as an extractive singularity of the country. In fact, the processing factory located in Vallecas transforms about 400,000 tons per year out of a global production estimated at 600,000. The strategic importance. High purity sepiolite is the basis of flame retardant additives essential for the cable, pipe, automotive and construction industries. These components allow Europe to replace antimony oxide, a raw material that is today imported almost exclusively from China. Furthermore, the mineral is the core of the project MADBATa Madrid initiative to develop high-performance electrodes for electric vehicle batteries. The economic impact projected by the concessionaire company, Tolsa, is ambitious: a turnover of 113 million euros, with more than 53 million destined for international export. The emptying of the water and the promise for 2037. To resume extraction, the first step will be to evacuate the water accumulated during two decades of inactivity. The Ministry of Economy defends this intervention under an argument that transcends the industry: citizen safety. The regional administration emphasizes that it is not a natural lagoon, but rather a deep mining hole with clay soils that, as they warn in their reports, act like “quicksand.” Despite the fences and signage, the place has become a recurring clandestine bathing point. Tragedy has struck this enclave on several occasions: since 2012, three people have lost their lives due to drowning in these waters, including the death of a minor in June 2021, according to the files of Europa Press. Given this danger, the Community of Madrid promises that, upon completion of exploitation in 2037, the area will be restored through a “safe and planned reconfiguration” that will create new controlled lagoons. The clash with the neighbors: the destruction of an ecosystem. However, the reactivation plan clashes head-on with neighborhood and environmental opposition. The Regional Federation of Neighborhood Associations of Madrid (FRAVM) and various groups have denounced, in statements spread by Europa Pressthat the work will mean the “destruction of the Laguna Grande.” The associations deny the official version about the origin of the water, ensuring that it has a phreatic character and is connected to a deep aquifer. In addition, they warn about the impact on biodiversity—especially in breeding colonies of the sapper planea protected bird—and about the proximity of mining activity to homes, sports facilities and educational centers. For organizations like Ecologistas en Acción and SEO/BirdLife, This extension is a bucket of cold water: postpone sine die the long-awaited project of converting the Ambroz environment into a large “Eastern Country House”, integrated into the Metropolitan Forest. The groups have not been slow to react: they are already preparing allegations and keeping open the possibility of taking legal action. The price of European autonomy. The Ambroz lagoons conflict perfectly illustrates one of the great industrial and environmental crossroads of the present. On the one hand, the undeniable geopolitical need for Europe to secure strategic materials to lead the energy transition and stop the Asian monopoly. On the other hand, the high ecological cost that this strategy requires at the local level. Madrid has decided to shield its sepiolite mine in favor of the technology industry, but the price to pay will be to empty – at least for the next decade – the oasis that nature had silently claimed in the southeast of the capital.

97% of a key mineral for Europe comes from China. Spain has a plan of 197 million to turn it around

by

Constant technological development has unleashed a silent but relentless geopolitical war. At the center of the target are rare earths and critical minerals, essential for manufacturing everything from mobile phones to electric cars or wind turbines. Nowadays, how to explain Europa PressEurope is in a situation of extreme vulnerability: 97% of the magnesium we consume comes from China and 98% of the borate we import from Türkiye. However, the solution to this deep dependence could be buried under Spanish soil. A new plan. As detailed in the National Mining Exploration Program 2026-2030 (PNEM), the official document promoted by the Government of Spain20 of the 34 raw materials that the European Union classifies as fundamental have been detected in the Iberian Peninsula. Of them, 17 are considered strategic due to their high technological and defense impact. To map and take advantage of this “treasure”, the Executive has launched an ambitious plan. The financing table of the PNEM itself projects a total investment of 197 million euros for the five-year period 2026-2030, adding public financing, aid and private investment that is expected to be mobilized. A breath for Europe and an opportunity for Spain. The European roadmap, crystallized in the Fundamental Raw Materials Regulation (Critical Raw Materials Act or CRMA), is very clear: guarantee access to a safe and diversified supply. By 2030, the European Union has set a goal of extracting at least 10%, processing 40% and recycling 25% of its domestic demand for these materials. In this context, Spain is not a secondary actor, but is the only producer of strontium in Europe, hosting 15% of the world’s reserves in the Montevives and Escúzar basin in Granada, and holds the position of second largest copper producer on the continent. according to data provided by Europa Press. The main focus of exploration is located in the Variscan or Iberian Massif, an extensive geological strip that crosses the west of the peninsula from Galicia to Andalusia, passing through Cantabria, Asturias, Castilla y León and Extremadura. The official document highlights, within this great massif, the so-called Central Ibérica, Ossa-Morena and South Portuguesa Zones as priority areas for general exploration. The private sector takes positions. On a practical level, intentions are already being translated into business movements on the ground. In Extremadura the Junta has granted a license to explore an area of ​​49,500 hectares in the Cáceres regions of Los Ibores and Campo de Arañuelo. In Andalusia, specifically in Jaén, the Australian company Osmond Resources will promote the Orion projectcovering 228 square kilometers in the former mining region of Linares-La Carolina to search for unusually high concentrations of rutile, zircon and rare earths such as neodymium. For its part, the European Commission has already blessed seven strategic projects in Spanish territory to protect the supply, located in enclaves of Ciudad Real, Orense, Cáceres, Badajoz, Huelva and Seville. Cutting-edge technology versus “pick and shovel”. The National Mining Exploration Program does not contemplate blindly digging holes. The Ministry’s text outlines six great performances interconnected to locate these raw materials. The process will begin with an exhaustive review of historical data and geoscientific reports, followed by the preparation of highly detailed geological-mining cartography. From there, technology will take over. Geochemical soil prospecting campaigns and complex isotopic analyzes will be carried out to find anomalies in the terrain. In addition, cutting-edge geophysical techniques will be deployed, using everything from airborne gravimetry and magnetometry equipment (planes and drones), to remote sensing using high-resolution hyperspectral and satellite images provided by the European Space Agency. All of this will be complemented by carrying out physical surveys to confirm the mining interest of the anomalies. Finally, as the official plan highlights, all this huge amount of data will be processed using algorithms, artificial intelligence and machine learning to generate predictive models of mineralization. The inevitable clash: Mining vs. Biodiversity. However, technology collides head-on with strict environmental reality. The clearest example is in Campo de Montiel (Ciudad Real). There, the company Quantum Minería has been trying to exploit a promising monazite deposit to extract rare earths. But the project has encountered strong neighborhood opposition due to the very high water consumption it requires and an unexpected defender: the iberian lynx. The recovery of this feline’s territories in the area has become a major legal obstacle for the mining company, paralyzing permits due to fear of destroying its habitat. Although before the environmental alarms go off, it is important to make a fundamental point: this National Program serves to know what we have, it is not an authorization to dig it up. The Ministry’s own document clarifies that the plan does not establish “binding or indicative objectives” for exploitation. That is, it is a purely prospective roadmap and data collection that does not compromise or zone the territory to open real mines. The mine is in the “garbage”. Faced with this paralysis and the immense difficulty of opening new mines in natural areas, Spain has an ace up its sleeve: secondary mining and the circular economy. The National Program reserves one of its main transversal lines to respond to article 27 of the European regulations (CRMA), thoroughly investigating the economic potential of mining waste facilities that were closed or abandoned in the past. The Ministry document remember thatalready in the 80s, an inventory was prepared that cataloged 21,673 waste structures (rafts and waste dumps) spread throughout the national territory. Now, the State’s objective is to review this catalog and promote geochemical characterization work to recover those fundamental raw materials that, at the time, were not of interest or could not be extracted and were discarded. As pointed out Europa Press, Research teams from the University of Seville led by professors Joaquín Delgado and Antonio Romero are already working in Río Tinto (Huelva) designing experimental plants to recover valuable metals and rare earths from the acidic waters of abandoned mines. Even beyond the mine. A clear example of this circular bet is the RC-Metals projectled by the National Center for Metallurgical Research (CENIM-CSIC). … Read more

why 14 municipalities of Guadalajara have rebelled against Europe’s “mineral sovereignty” plan

by

The silence that guards the 15,000 hectares of the Sierra Norte of Guadalajara is not empty, it is an inheritance. However, that calm has been disturbed by the flash of a promise as old as it is dangerous: gold. The emergence of Oroberia SLU—subsidiary of the Australian multinational Global Mining Enterprises—has fractured the peace of the region with a request to drill into its bowels that has awakened the ghosts of exploitation. The origin of the conflict. The alarm went off in the spring of last year. Oroberia SLU is a company established only in March 2025 with a capital of only 3,000 euros, what woke up immediate suspicions about its solvency and transparency. Through three projects called “Gua”, “Dala” and “Jara”, the company aims to explore a territory that covers from La Toba to Atienza. This new “mining wave” finds its legal protection in the EU Fundamental Raw Materials Regulation (in force since April 2024), which seeks to cover 10% of the extraction of strategic supplies on European soil. What Brussels sells as “patriotic resilience” in Guadalajara translates into accelerated permits and a disturbing ease in classifying private projects as “strategic.” As Javier Cantero, mayor of La Toba, warns in The World“the companies are not state-owned… They will sell the raw materials to whoever pays the most.” The drilling plan. Thanks to “JARA” Permit Environmental Restoration Planwe know with technical precision the scope of the intervention. The company planned: Deep drilling: Rotational drilling with core recovery between 300 and 400 meters deep. Phases: An initial phase of six surveys per permit, expandable to another six if the results were favorable. Surface impact: Occupation of about 200 square meters for each drilling platform. The real danger, as experts explainis that if the mineral is less than 200 meters away, exploitation would inevitably be open pit. This would involve removing massive amounts of soil, raising dust loaded with microcrystals that can cause silicosis and other lung diseases, in addition to requiring enormous water resources and containment ponds for chemical treatments that could leak into the subsoil. The setback of the Board. Oroberia’s strategy of presenting three different projects has been described as “fragmentation” to avoid controls. However, in November, the Provincial Delegation of Sustainable Development of Guadalajara issued a historic resolution: Mandatory unification: The company must encompass “Gua”, “Dala” and “Jara” in a single project of 14,600 hectares. Ordinary Evaluation: The simplified evaluation (more agile) is denied and an ordinary Environmental Impact Assessment (EIA) is required, much more rigorous and slow. This decision is a victory for the neighbors. As Alberto Mayor points outfrom Ecologistas en Acción, this allows the “synergistic impacts” to be evaluated and forces the company to face the reality that 63% of the affected land contains habitats of community interest and protected species such as the Iberian wolf, the golden eagle and the ricotí lark (the latter in danger of extinction). A total and transversal opposition. The social response has been overwhelming. According to Ecologists in Actionnearly 800 allegations have been filed. The alliance is unprecedented because it includes mayors of all political colors (PP, PSOE, IU), hunters’ associations, environmental groups and even local parishes. The fear is not only environmental, but also economic and patrimonial. The “Jara” project would directly affect to towns such as Sigüenza and Atienza, committing their candidacy to UNESCO World Heritage status for the “Sweet and Salty Landscape”. Furthermore, mining would “a death blow” to already consolidated sustainable tourism projects, such as the Camino del Cid or the seal Starlight Destination. What will happen now? The company has two options according to local media: give up in the face of administrative obstacles and social pressure, or present a new unified environmental study that will be subjected to a new period of public exhibition. However, the scenario is complex. Currently, Spain is experiencing a mining rediscovery. While in Guadalajara the fight against gold is underway, in Galicia work has already begun to extract tungsten in the San Juan mine (Ourense), and in Jaén, the company Osmond Resources (linked to the same directors of Oroberia) has received permissions to investigate rare earths in the “Menipe” project. The ghost of 1973. One of the most critical points is that mining in Spain is governed by a Mines Act of 1973written in the last years of Franco’s regime. This law converts the mineral resource into public domain: if the administration grants permission, the owner of the land is obliged to let the company enter or face expropriation. This legal defenselessness is the fuel that fuels the rage of the fourteen Guadalajara municipalities. The value of what is not seen. The conflict in the Sierra Norte of Guadalajara is the representation of a clash of worlds. On the one hand, an extractivist vision that sees mining grids in the mountains and profits in the Australian stock market (where gold is trading upwards as a safe haven). On the other hand, some towns that, in the words of the mayor of Ríofrío del LlanoMaite Pérez, they only ask that the depopulation laws serve so that people live in their land and not to make it easier for them to be kicked out. For now, the Sierra Norte still stands, guarding a geological and biological heritage that, as your neighbors say“it has no price because it is not a commodity.” Image | freepik Xataka | The problem with Greenland is not that it does not have minerals: it is that getting them out of there is an engineering nightmare

The Critical Mineral Companies of the West are trapped between the US and its best client: China

by

Western companies that are dedicated to the extraction and processing of critical minerals are between the sword and the wall. These raw materials They are fundamental for many strategic industriessuch as those of semiconductors, telecommunications, advanced weapons or electric car, so USA and China are using them as a resource to exert pressure on the other. This situation represents a very serious problem for Western mining companies because Donald Trump’s government has imposed very strict controls to China of these minerals, as well as High tariffs. Rio Tinto and BHP are the world’s largest western miners, and its best client is China. In fact, According to Volt Rush In 2024, 57% of Rio Tinto’s income came from China compared to 16.7% of the US. Losing the Chinese market is not an option for these companies, so the managers of the two companies I just mentioned have met with President Donald Trump in the White House with the purpose of defending their interests and protecting their position in China. However, they also have something to offer to the Administration: the possibility of reinforcing the US supply chain by opening new deposits in the country, such as the “Resolution Copper” project of Arizona, delayed for years due to the opposition of the Apache tribe of San Carlos. China dominates an essential market for the US and its allies: that of rare earths On April 4, just 24 hours after Donald Trump announced the taxes that he was going to apply to the importation of most products from abroad, The administration led by Xi Jinping responded. And he did it forcefully. In early December 2024 He chose to prohibit The export of some critical minerals to the US, among which were three essential metals for the chips industry: Gallium, Germanio and Antimony. Shortly after the Chinese government added two more critical metals to its list of export restrictions: the Scandio and the Disposio. These chemical elements are probably less known than metals prohibited by China previously, such as Gallium or Germanio, but They are at least so important Like the latter because they have a fundamental role in the industries of integrated circuits, telecommunications and the manufacture of storage devices. Many companies have high -power magnet reservations made with rare earths, but possibly they will only allow them to subsist a few months The ability to put pressure from China had not yet been extinguished. Just ten days later, on April 14, the Administration did not hesitate take another step forward With the purpose of putting in check, in addition to the industries that I just mentioned, those of electric cars, aeronautics and advanced armament. To achieve this, it effectively suspended, in addition to the export of the most valuable rare earths, that of high -power magnets that have a critical role in the industries that I have cited in this same paragraph. Chinese authorities are retaining in ports throughout the country not only rare earths, but also high -power magnets acquired by electric cars manufacturers throughout the planet, aerospace companies, chip factories and armament companies. Many of these organizations They have high -power magnet reservations Made with rare earths, but possibly they will only allow them to subsist a few months. Europe in particular is in an extremely delicate position. China’s export controls are directed mainly to the US, but the old continent It does not remain unscathed. At least for the moment. In fact, in Germany, which as we all know is the heart of the European car industry, There are already experts who assure that if China continues to retain rare earths and electric motors some essential parts of the electric cars production chain will stop in a few weeks. For the European car industry this blow would be very difficult to fit. European companies that are dedicated to the manufacture of semiconductors are also in a very compromised situation. According to Reuters Many European chip production lines They will stop very soon Due to the shortage of crucial supplies, which has led the European Chamber of Commerce to meet with officials of the Ministry of Commerce of China to ask them to allow rare earth supply to European companies that are dedicated to the production of integrated circuits.

All their missiles, fighters and bombs need a mineral that China has vetoed them

by

The news took place in April. So, the Chinese government He formalized his answer To tariffs approved by the United States adding to its list of export restrictions a series of metals that went unnoticed for the general public. However, when the United States and Europe have been made numbers To replenish their arsenal sent to Ukraine and the East, they have encountered a problem of difficult solution. Them A component is missing essential. And only China has it. The mastery of the samario. Yes, China has exposed a critical vulnerability in the Western Military Supply chain by imposing severe controls to export Samarioa strange metal for the manufacture of heat -resistant magnets used exclusively in military applications. These magnets, fundamental in components As missile engines, smart bombs and combat fighters, they are irreplaceable due to their ability to withstand extreme temperatures without losing magnetic strength. Since China produces the entire samarium of the world, and has stopped its export under a new licensing system claiming national security motifs, the United States and its European allies now face the real possibility of Not being able to replenish Its advanced armament reserves, especially and as we said, after its intensive deployment in Ukraine and East. Announced dependence. Had the New York Times That the agency of China is not new: since the 70s, the Western Armed Forces trusted a French plant that closed in 1994, unable to compete with the cheap and environmentally lax production of the Chinese city of Baotou, in the interior Mongolia. Despite decades of dispersed warnings and efforts, such as Mine reopening From Mountain Pass in California after the Chinese embargo on Japan in 2010, the United States never developed a viable production of samarium. Leaf, reactivated in 2014broke the following year for Chinese competition. MP Materials, its new owner, relaunched operations in 2018 and received pentagon funds to process samarium, but never installed The necessary equipment for lack of customers willing to cover high costs of the reduced market. Meanwhile, another project backed with federal funds (a Lynas plant in Texas) was never built after regulatory problems In Malaysia. The lost link. And here comes one of the keys to understanding the “problem” of these nations. The largest samarium user in the United States is … Lockheed Martinwhich uses around 23 kg for each F-35 plane. The new Chinese regulations not only stop the direct flow of samarium, but also requires based licenses In the final consumerwhich blocks indirect exports to military contractors. Although China has granted permits for certain magnets destined for the automotive industry (such as those used by disposses or terbio in brakes and addresses) has not given signs of releasing Samario’s supply, given its limited civil application. This hardening coincides with Chinese sanctions to US contractors linked to Weapons sales to Taiwanwhich reinforces the use of samario as a geopolitical pressure tool. An X-35A JSF performing flight tests at the Edwards Air Base in California Other critical applications. A few weeks ago Japan Times summed up Very well what rare metals consisted of and how they influenced the different industries. The seven metals restricted by China (Terbio, Itrio, Disposio, Gadolinio, Luthacio, Samario and Scandio) fulfill crucial functions in both civil and military industries, from the generation of clean energy to the advanced defense. The Terbiofor example, it provides thermal resistance to the magnets used in submarines and aircraft, but it is one of the most scarce elements even within the rare earth deposits themselves. The ititriumvital in treatments against cancer and superconductors, it has historically been extracted in the United States but must still be processed abroad. Disposioresistant to heat and key in the energy transition, is essential for magazine turbine and electric cars magnets, and also for nuclear reactor control bars. The majority of the supply of these three metals goes to Japan, South Korea and, to a lesser extent, to the United States. The nuclear spectrum. For its part, The gadolinio It is widely used in magnetic resonances due to its magnetic properties, but also appears in nuclear reactors and electronic components. The Luthaciodenser than other elements of this list, acts as a catalyst in oil refineries, while the samario, as we said, protagonist in recent blockages, forms magnets that resist extreme temperatures and that are essential in combat planes, turbines and advanced guide systems. Finally, The Scandioof marginal production for half a century, it has applications in military aviation, bicycles and tracers to detect leaks in pipelines, thanks to its resistance and radioactive properties. As We have counted other times, the lack of infrastructure to separate and process these materials in the United States or Europe aggravates their structural dependence on China, which already supplies More than 90% of American imports. Asterisk. Interestingly, China has not included in this round to the neodymium and the praseodimiumtwo of the rare metals most used in the manufacture of permanent magnet motors, essential for electric vehicles and wind turbines. These two elements are still produced in the Mountain Pass mine, in California. Even so, American production barely reaches a fraction of global demand, and China’s dependence is still critical. A strategic urgency. In short, in a context in which the United States and its allies try to accelerate the replacement of reduced arsenals and ensure deterrence, The bottleneck From the samario he highlights the risks of having subcontracted for decades the strategic inputs to China. The commercial conversations In London they seek to reactivate the flow of these metals, but the expectations that Beijing reversed their new licensing system are rather scarce. Meanwhile, the United States and Pentagon face the dilemma of how to reconstitute a national supply chain for an essential resource whose production, for its cost and limited scale, has proven to be commercially unfeasible No sustained subsidies and long -term political commitment. The samario, invisible to the general public, thus becomes a symbol of a new era of technological and military rivalry, where industrial sovereignty is again a … Read more

The bone of the sardines is an important source of calcium. And it is not the strangest food that this mineral gives us

by

Calcium is a fundamental element for our body and, especially. Surely we have heard throughout our life (and especially in our childhood) that you have to drink milk to gain calcium For our bones. While milk is far from being the only food capable of nurturing our bones with this mineral. First of all, perhaps it is convenient to explain why we need calcium, because the notion that calcium is good for our bones, although exact, does not give us excessive information either. Fundamental for the formation and maintenance of bones and teeth, calcium is the most abundant mineral in the human body and 99% This is precisely in our bone structure. That is why His lack It can cause problems such as rickets in children and osteoporosis in adults. But calcium also exercises as electrolytea mineral with electric charge that our body uses for various functions. In it Case of calcium Specifically, its presence in muscle cells allows us contract and relax our muscles and transmit signals through the nervous system, in addition to helping blood and hormones circulate through our body. It is difficult to talk about calcium without starting with dairy. These are the foods that we most associate with the element. Milk contains abundant calcium and some of its derivatives contain even more. In a natural yogurt, low in fat (about 125 grams) we can find Approximately 248 milligrams of calcium. Some cheeses contain calcium concentrations that are even superior. However, there are foods that can contribute both calcium and dairy products. Or even more. Some calcium sources can be surprising. We can find abundant calcium in vegetables such as the Brocoli, Kale or Collized, or in the Berza or cabbage. But perhaps the most surprising plant source is another sheet: that of the ortiga. Cooked, this urticating plant can contribute us Around 125 milligrams of calcium per 100 grams of product. Diverse sources Another important calcium source is in fish. We know that calcium in our body is concentrated in the bones, but the bones of other animals also have calcium. Normally we do not consume food with bone, but there are exceptions. For example, the thorns of The sardines. This makes this fish, consumed with bone as we usually do for example when we eat it, be it Another unique calcium source. The drinks that we usually use as an alternative to milk are, curiously, a source of calcium in themselves. The reason is that these are usually made from calcium -rich foods. Soybean is one of them (and therefore also other derivatives such as tofu), but also some nuts such as almonds. Some of these drinks can also be enriched with calcium to strengthen this contribution. In general, we can also find various foods enriched with calcium, including dairy, juices, and flours and their derivatives. We can even find Calcium supplements If we require them. The calcium content of a food is not the only thing that should matter. The reason is that our body does not always absorb all calcium present in these. In the absorption of this mineral, another nutrient plays a fundamental role, the Vitamin d. This micronutrient plays a key role in the absorption of calcium and also phosphorus.
