This is the clear protein

by

In these days of heat wave, you want to drink something cold, light and refreshing. In Tiktok, it is easy to be confused: among so many drinks of drinks with vibrant colors, one would think that he is facing a video More on flavored water. Although it seems to the naked eye, it really is Before clear proteinand goes beyond a flavor water. Clear protein. EITHER Clear Protein It is a variant of the powder protein of traditional serum, but with a fundamental difference: it undergoes additional processing to eliminate fats, carbohydrates and lactose. As a result, a powder is obtained that, when mixed with water, gives rise to a light, translucent drink and without milky texture. Technically, it is composed of isolated from hydrolyzed serum, which facilitates its digestion. In a report for GQthis trend has described as a way of maintaining protein consumption without going through a creamy shake: “It dissolves as a sporting drink: light, fruit flavor and without lethal or sticky texture.” One more fashion? The rise of clear protein is not explained only by its functional characteristics, but by Your presence in social networks. The images of bottles with colorful and crystalline drinks are part of the new post-gymnasium ritual. As has developed An article in Vogue, no foamy milkshakes: now what is carried is something that looks like flavored water. And that sells. “It is visually attractive (who does not like transparent and colorful drinks?),” Said Lauren Manaker, a nutritionist cited by the same medium. But popularity also responds to erroneous perception: that the clearest and lighter is necessarily healthier. In this context, Nuria Esteves, clinical nutritionist, He warned in Xataka that the problem is how this type of products is positioned: “It is not a priority in our food as we are sometimes tried to sell.” Clear protein can be useful, yes, but it should not be considered a substitute for real food or a mandatory superfood. Is it equally protein? Yes. Although appearance and texture change, clear protein remains a processed supplement. It is not a magical drink or is nutritionally superior just because it is easier to drink. In fact, products such as Clear or Boost Breeze, clear protein versions, exist for years and are common in clinical environments, according to They have pointed out In Vogue. The difference is that now the format has become a trend, thanks to striking flavors, elegant containers and campaigns aimed at those who seek physical performance without complicating too much. What differences are there? Although both the clear and the traditional protein start from the same ingredient – the whey – the truth is that the final result is little like. Not only does the elaboration process change, but also the way in which it is drink, it is digested and even perceived. Let’s start with texture: classical protein is mixed with water or milk and becomes a thick shake, with body, even somewhat heavy. Instead, clear protein dissolves as if it were a juice: light, fluid and without a trace of milky density. For its part, the taste also makes a difference. While traditional versions usually imitate desserts such as vanilla, chocolate or cookies & cream, the whites bet on fruit and refreshing flavors, such as strawberry, lemon or mango. More than a supplement, they look like a sports drink. And if we talk about digestion, whites usually have an advantage. Being made with hydrolyzed serum, its structure is partially decomposed, which facilitates its absorption. For those who have a sensitive stomach or some lactose intolerance, they can be a more comfortable option. In terms of composition, both offer similar amounts of protein by ration. However, clear versions usually have less fat, less carbohydrates and less lactose, which in practice also means less calories. Is it for everyone? Not necessarily. In a recent report in this mediumnutritionists agreed that the protein powder, clear or not, can be useful in concrete contexts, such as older people, cancer patients or sarcopenia, who have difficulties in eating or athletes in the muscle gain phase. You can also facilitate adhesion to training if you are perceived as a “reward” post effort. However, specialists insist: you should not replace complete meals. Thinking that a “does not fat” shake because it is fitness is a frequent mistake. In addition, using it from fear of eating or as the only source of nutrition can lead to a conflicting relationship with food, according to Nuria Esteves nutritionist. One more option. A clear protein is not a revolution, but it is not smoke either. It can fit in many routines, provided it is understood by what it is: a supplement, not a magical solution. Sometimes it is just that: a fresh drink with a good flavor that helps you add proteins without complicating. The important thing is not whether it is clear or creamy, but if it really fits your diet.

In the Holy Trinidad Crossfitera, a supplement makes its way to elbows next to creatine and protein: Ashwagandha

by

Get an increase in muscle mass is complicated and, contrary to what we can think, much of the “training” is not done in the gym: we do it In CamOh In the kitchen. A good diet that Cover our needs When training is vital, and when the food does not arrive, supplements come into play. And inside the gym, especially in Activities such as CrossFitthe holy grail of supplementation is the one composed of proteins, creatine and an unpronounceable compound. The Ashwagandha. Cocktail. If there are two supplements studied and backed by scientific evidence, those are the Powder proteins and creatine. Proteins are one of the three basic macronutrients and, although, Sometimeswe can consume more proteins than we need, it is also being observed a lack of them in certain people for disease or diet reasons. To create muscleproteins are essential and we look for it in milkshakes and Even in coffee. Supplementation with milk whey or plant compounds such as soy or peas It favors muscle gain and muscle repair. On the other hand, creatine is a supplement that focuses on increasing muscle phosphocreatine deposits, allowing faster regeneration of the energy molecule that is used in intense and short -term activities, such as weightlifting. Evidence. The taking of both supplements in athletes is recommended, almost essential in cases such as those of people with vegan diets (Because there are proteins of plant originbut creatine is found in meats and fish), but still, and As with caffeine, they are surrounded by myths. There are those who think they are like Anabolizing steroidsthat damage the kidneys, which causes the hair to fall and that, if we train, take them and gain muscle mass, we have made “trap”. The truth is that the two supplements, especially creatine, are widely Backed for scientific evidence. Over the years they have been put under the magnifying glass in numerous investigations, without find Myths They have penetrated many people. In fact, thanks to these investigations, every time They discover more creatine benefits, such as its Neuroprotective effects on the brain. Ashwagandha. Within the sports scene, there are not so many doubts about the effectiveness of these supplements (provided we carry a Good dieta proper rest and a Correct trainingof course), but in recent years there is another name that is gaining weight, placing with creatine and protein shakes such as the ‘trinity’ of supplementation. We talk about Ashwagandha, another supplement that is gaining popularity in the world of fitness due to a very interesting potential: reduce general stress, improve physical performance and also recovery. Inter alia benefits how can it be Improvement in sex quality. But … what is this? SOMNIFERA WITHANIA. As protein and creatine, Ashwagandha does not come out of nowhere, and it really is something that has a long journey. It is an adaptogen, which is still a substance of plant origin that helps the body to balance. Its use comes from traditional medicine and is a plant known as SOMNIFERA WITHANIA That, as we say, it is gaining popularity outside that world of traditional medicine thanks to the studies that are supporting its benefits when training. Among its effects, it has observed which reduces cortisol, or stress hormone. This favors Recovery and has positive effects on sleep quality, so it affects that important moment in which muscle regeneration occurs. Has anti -inflammatory effects and have also studied Its effects on muscle strength and physical resistance, also observing improvements in cognitive function, male fertility and improvements in glucose control and blood pressure. Synergy. This interest in adaptogens responds to the search for more natural solutions for stress in a society in which it has become a first -order problembut it is also sneaking into the gym, with several important brands of sports supplementation offering their products. Currently, I know indicates That the benefits are consumed at intervals of six to eight weeks in doses of about 600 mg daily, but it is also indicated that long -term studies and more types of populations are required to confirm both benefits and to rule out adverse effects. In the end, Ashwagandha is not a supplement as studied as protein powders or creatine, but these incipient analyzes are positive, accumulating favorable evidence. And, precisely, among the three supplements we have a cocktail that works in protein synthesis, adaptation and muscle recovery. And, of course Influencers of the fitness world They are also creating content on the benefits of Ashwagandha, helps more people interested in use. At least, on this occasion, science seems to be supporting those recommendations, and something important is that (especially in the case of powdered protein), they are supplements, not substitutes and the essential thing is to carry a balanced diet.

Powder protein has become the star accessory of modern well -being. Nutritionists have something to say

by

There is a silent ritual that is repeated every afternoon in gyms. Sudaded hands open the backpack compartment, they take out a boat with bright letters – vain, chocolate, cookies & cream -, they pour it into a Shakerthey stir hard and drink almost devotion. It is the protein milkshake, faithful companion of those who seek performance, muscle or simply the feeling of having fulfilled. The scene has become as common as mid -morning coffee or avocado toast. The powdered protein has gone from the industrial sacks of bodybuilders to the shelves of the supermarket, to the shop of the purchase of office workers, students and parents in a hurry. His promise is tempting: strength, health, body. Its form, practical. But … Is it really necessary for everyone? Is it helping us or, without realizing it, we are becoming dependent on this sweet taste dust and fast promises? To understand it, we have spoken with three nutritionists who know their benefits well as their risks. Because behind each milkshake, there is more than protein: there are decisions, habits and sometimes, a desperate desire to control the body. Powder protein: Miracle tool? Saray López, Nutritionist and personal coach, has been decisive: “I am totally in favor of its use, except intolerances, because it has no contraindications and can help reach daily protein requirements.” Instead, Jesús Guardioladietitian-nutritionist, has offered a more nuanced vision: “If we carry a balanced diet, we will not need any type of protein supplement to meet our needs.” His approach focuses on preventing supplementation from replacing a real diet. For its part, Nuria Estevesclinical nutritionist, goes beyond the functional and enters the symbolic: “It is not a priority in our food as we are sometimes tried to sell.” For her, the problem is how it is positioned in the market: as a kind of mandatory superfood, when in reality its utility is limited and very contextual. Is it for everyone? The three experts have agreed that dust protein can be beneficial in certain clinical or personal contexts. Saray López has accurately detailed it: people with eating disorders, older adults with chewing difficulties, cancer patients or sarcopenia, people in the stage of muscle gain or even workers who eat in front of the computer. In addition, Guardiola has highlighted its value as a “motivator” post -entry: taking the shake as a small reward can help create adherence to training. Now, who should avoid them? The Esteves nutritionist is overwhelming: “It can be a risk in people who do not have a good relationship with food, or who use it as a complete food substitute. We no longer talk about health, but about anxiety, rigidity and fear.” For his part, Jesús Guardiola has added people with renal pathologies to the list, who must have strict control over their protein intake. The dependence of the supplements. According to Nuria Esteves, there is a growing trend towards the use of supplements as part of the “fitness pack”: “The idea has spread that without supplements we are not doing well. And that can feed the obsession with the perfect body.” Jesús Guardiola also perceives this agency in practice: “Many people prioritize the shake before real food. But if you don’t have a structured diet, taking a shake will not do anything.” For him, order matters: first food, then – if necessary – the supplement. More is not better. The rise of powdered protein consumption has brought with it a series of errors. One of the most common, according to the three experts, is to take more protein than necessary, under the false belief that the more consummated, the better the results will be. However, the body has an absorption limit, and excess – beyond not providing benefits – can move other important nutrients. For his part, Jesús Guardiola has pointed out an especially common error: to think that, because it is a “fitness” product, it does not fat. “People believe that a protein smoothie have no calories or have very few, and it is not. It is one more food and provides energy, like any other, ”he has warned. It is also frequent risk behavior ”. Are all proteins the same? Spoiler: no. Not all powder proteins work the same. Jesús Guardiola He has clarified that we must individualize: “You cannot recommend one for all. It depends on the person, their tolerance and the moment of the day.” López has recommended serum protein (Whey) if there are no intolerances, due to its most complete amino acid profile. Casein, slow absorption, can be useful before sleeping. And vegetable proteins, such as pea or rice, are good options for vegans, provided they are well formulated. Besides, Esteves He has added an essential criterion: bioavailability and digestive tolerance. It is not just about taking protein, but how it processes it and absorbs the body. And the label? If you are among the options to start taking it, the three have agreed that it is important to read before mixing. Search for complete proteins, verify the real proportion of protein (at least 70-80%), avoid excessive artificial sweeteners and make sure the brand is reliable. Saray López has alerted about a hoax that many brands use: “Some trapped the aminogram by adding loose amino acids to lower the cost. That increases the nitrogen value, but not its nutritional value.” Neither bad nor miraculous. Nor is it essential. It can be useful if used with criteria, but does not replace a varied, adapted and healthy diet. As Nuria Esteves summarized: “The focus should always go towards a diet that respects and adapts to the context of each person.” Image | Pixahive Xataka | The “natural” alternative to Ozempic sounds very good and much cheaper than the medicine.

If the question is how to increase protein intake, the answer is the ‘proffee’

by

Proteins should be one of the pillars on which a balanced diet. Let’s have the goal of keeping ourselves in good shape, losing weight or gaining muscle mass, Proteins are essential. However, it is not always so simple get to the recommended amountand that is where the preparation industry has found a reef. As? With processed foods that play with marketing and move to others whose protein contribution is already important. There are also protein supplements, of course, and are interesting in diets in which the physical load is considerable. But what if instead of taking only one Protein milkshakeDo we mix them with coffee? A few years ago appeared In Tiktok the fashion of the ‘proffee’ resulting from combining Protein and Coffeeand far from being something that was forgotten, it has kept In time and that is not as a bad idea as it may seem. Brands like Starbucks did not take long get into the carbut these protein coffees are something you can do at home very easily. Although you have to have a little eye combining the ingredients so that the result is not a drink of the Averno. THE CAFFEA WITH PROTEINS: ATITIING COMBINING There are many mixtures that are doubtfulbut that of coffee and proteins looks like one more. On the one hand, we have coffee, a food that, beyond its energy contribution thanks to the caffeine, It is very healthy. You have to be careful with the amount of caffeine that we eat and It is not good for all activitiesbut there are more and more studies that support the beneficial effects of coffee About our body. On the other hand, powdered protein. There are several types, but the most common are those of whey, casein and soybeans. Here You have to be careful Because it is a double -edged sword and, the more processed and additives, worse. For example, you have to control the added sugar level or the types of sweeteners they use because the labels of some powdered proteins are authentic Bibles. Above all, if it is a quality powder, it is much easier to consume a shake than a huge amount of eggs. Made the presentations, Let’s go to ‘Proffee’. Although There are suitable intervals To take protein, the truth is that we can take a shake when we feel like it. The important thing is Distribute that macronutrient among all meals Daily, but mixing them with coffee is interesting in two specific moments: In that first morning coffee We introduce protein at a time when our body is open to receive it. In that coffee we drink before training. We gain an extra energy, we contribute to the total daily protein that we should ingest and, in addition, we have the positive effects of caffeine for our sports practice. And preparing the drink does not have too much science. In fact, it is very possible that you already did it before the term ‘Proffee’ appeared on the network. Here my recommendation is that you do it as you like, but ideally you do not prepare a espresso And you add a church of protein, since the result is … well, disgusting. A simple elaboration is to unite a espressoa banana, milk (animal or vegetable) and a chip of vanilla or chocolate proteins in a crusher and make the shake. Banana and proteins sweeten the drink and mixture is curious, but it is quite good. You can remove milk if you want to consume less calories and change it for water, but that extra milk also adds proteins. You can also move from banana or find another fruit that can curdle well with coffee. What I would never do – and here each one can do what they want, but it is a recommendation – is Mix coffee with proteins that are not chocolate or vanilla. Proteins with neutral flavor, to citrus or strawberry are not too pleasant in that mixture. In the end, it is to play with amounts and ingredients until you find something that you like because, in this case, beyond a fashion with its own name on Tiktok, joining proteins and coffee is something that It can contribute a lot In active life styles. It would always be necessary to be careful not to replace meals for powders, since these real foods have a series of vitamins, minerals and other beneficial compounds and, above all, choose a protein shake that not up to sugar. And, if you test and you do not like it, do not take it that, despite the existence of the I think for humansfood is also to enjoy.

Losing weight without losing muscle is the great challenge of drugs such as Ozempic. A protein keeps the key to face it

by

It is usual for us to often get news about hopeful scientific advances made in mice. These experiments always leave a question in the air, if the discovery can be applicable to humans. This does not always happen, but sometimes MITCH Silence the expression of a simple protein in our muscles can lead to weight loss and, more, more, It can allow us to lose weight Without putting our muscle mass at risk. The protein in question is called Mtch2 (Mithochondrial Carrier Homolog 2), but has been nicknamed “Mitch” by those who study the compound and its effects. The last analysis of this protein and its associated gene has observed that its “erased” in human cells causes in these lower efficiency Energy What is perhaps more important, this silenced causes cells to stop using carbohydrates as a priority energy source and in place they preferably use body fat. Different fuels. The cells of our body need energy and billions of years of evolution have given rise to a series of biological mechanisms that allow us to maintain a calorie reserve that allow us to feed these cells in times of greater shortage. These mechanisms imply that our cells can resort to different fuels according to the situation. While the carbohydrates we consume and the fats that we use as a reserve are the main fuel Ozempic. From mitones to mitochondria. According to Explain the responsible teamthe new study has its bases in a previous experiment conducted with mice that observed in the rodents an “improvement” in their body composition in the form of “protection” against obesity and the development of more muscle fibers. This accompanied by greater consumption of greater oxygen consumption and an increase in resistance. The results were promising but left the team with a doubt, if it would be possible to “inoculate” the body against obesity by silencing the expression of a protein without this negatively affecting muscle mass. To look for an answer, the team went on to focus on the role of the mitochondría, the organelle in charge of providing energy to the cell. The key is in the fact that the “mitch” protein plays an important role in the merger of the mitochondria, a fusion capable of increasing the efficiency of these organelles. By silencing protein, organelles would lose the ability to resort to this fusion which also implies less efficiency and thereby a greater need to consume energy resources of our body. It only remained to prove if this was also true in human cells. Less efficiency, more consumption. They thus verified that by silencing the protein in human cells, the “mitochondrial network” was undone and, as expected, energy efficiency fell. This left the cell in a “permanent state of energy deprivation.” And what is more, the team also found that this led to the cells to prioritize the use of fats as a primary energy source, instead of other possible sources such as carbohydrates. “After erasing Mitch, we examined, every few hours, the effect that it had in more than 100 substances that take part in the metabolism of human cells,” pointed in a press release Sabita Chourasia, co -author of the study. “We saw an increase in breathing, the process in which the cell produces energy from nutrients, such as carbohydrates and fats. This explains the increase in muscle resistance of previous experiments in mice.” The details of the study were published In an article In the magazine Journal embo. An intermediate step. The study takes an important step in the long process between the first results in animal models and the design of a treatment for weight loss based on what was learned. In following studies, the team intends to elucidate new aspects about Mitch’s role in the accumulation of fat in the body. The fact that women usually have higher levels of this protein can help researchers discover if Mitch is also responsible for the differentiation of fatty cells.

How protein cult has turned the muscle into the new social networks trend

by

In the Basilica of San Pietro In Vincoli, in Rome, there is a sculpture that attracts the attention of many people for a simple detail. The work, Miguel Ángel’s “Moses”, the sculptor carved a small muscle on the forearm that is only activated by lifting the little finger. This almost invisible gesture, but essential for Michelangelo shows the subtle force and control. Today, centuries later, the bodies defined as if they were sculpted are trend. But this time, it is not about marble or art, but of protein, supplements and extreme routines. In the Chic Protein era. A new phenomenon that has gained strength in recent years, but now is the trend that marks on social networks. In 2023, products enriched with proteins had taken the supermarkets. From yogurts to snacks, the industry promoted the idea that greater protein consumption is synonymous with health and well -being. Now, that obsession has moved to the toned bodies: figures like Ashton Hall, Famous for its morning routineit is a clear example of that ideal of healthy life and sculpted body. A new welfare mantra? In the third season of The White Lotus, Saxon Ratliff, a character obsessed with exercise and body image, embodies perfectly This contemporary obsession with proteins. Interpreted by Patrick Schwarzenegger, the son of the iconic Arnold Schwarzenegger, Saxon not only loads with his personal blender so as not to miss his protein shakes, but also consumes popcorn enriched with “Khloud” dust of Khloe Kardashian, an obvious satire of the marketing of hyperproteic products. Saxon is not just a character obsessed with his muscles; It is a fitness symbol turned into pop culture, where protein blender is as essential as mobiles and smoothies are the new fashion coffees. Beyond the screens. This fictional portrait is a reflection of what happens with the boom of hyperproteic products, is it really necessary to consume 200 grams of protein in a shake, as Saxon does in the fourth chapter? Science has offered different perspectives. On the one hand, the main dietitian of MAY CLINICTara Schmidt, has affirmed that protein needs depend largely on the lifestyle, weight and health history, so he cannot affirm with certainty what is the ideal amount. Although it is recommended has pointed out To vogue that excess protein can cause inflammation and affect intestinal health, counteracting the initial benefits of these hyperproteic products. The path to (almost) perfection. Even the fashion world has embraced this new body form. Designers such as Demon and Hilary Taymour have presented collections that emphasize muscular silhouettes, evidencing how fashion adopts and amplifies the body ideals promoted by the culture of well -being, According to Vogue. However, not only fashion has imposed the standard, the viralization of medicines to lose weight as Ozempic and Wegovydeveloped to treat type 2 diabetes, they have become rapid weight loss products. And in the meantimephenomena like Skinnytok They promote restrictive diets and extreme exercise routines, with millions of visualizations that glorify thin and toned bodies. Social networks have amplified the obsession with the sculpted bodies, turning each physical transformation into a viral show. The distorted mirror. In this era where the body is the new canvas, body dysmorphia He has found A perfect breeding ground to spread. This disorder, characterized by an obsessive concern for defects perceived in the body, has reached alarming levels on social networks such as Tiktok and Instagram. In these platforms, filters, edited images and constant comparisons They have exacerbated The distorted perception of the body, especially among the youngest. A Health report has pointed out That the constant exposure to hyperdefinid bodies and perfect skins can lead to eating disorders and compulsive behaviors related to exercise. The psychologist specialized in TCA, Sara Bolo has explained to this medium that the worrying thing is that many of these apparently “healthy” behaviors hide eating disorders disguised as fitness culture. We see more and more full gyms and more people obsessed with not skipping a meal or training, and that is where the problem begins. It is not the exercise or healthy eating that is wrong, but the rigidity with which these practices are followed. In addition, he has warned: “In the end, it is not so much to take care of the body as forcing it to fit into an unreal mold that we see on social networks.” The end point. In a world where the image weighs more than the essence, where bodies are molded as sculptures and extreme diets disguise themselves as self -care, the inevitable question arises: to what extent are we really taking care of our bodies or simply molding them to fit into an unattainable mold?

We are increasingly clear that our microbiome is key to our health. Our protein sources can also alter it

by

Little by little We started realizing Of the importance of our microbiota, especially as regards the microorganisms that inhabit our digestive system, our gastrointestinal microbioma. Aspects of our health that in principle They would not seem connected To what happens in our intestines seem to have some kind of correlation with that flora of fungi and bacteria that coexists inside us. Different proteins, different microbiome. A recent study has observed That the food source of protein can alter the composition and structure of our intestinal microbiome, that is, of the set of microorganisms that inhabits our digestive system. The experiment, conducted with mice, observed important variations in the microbiota associated with changes in the diet. “The composition of gastric microbiome changed significantly every time we change the protein source,” pointed in a press release Alfredo Blakeley-Ruiz, co-author of the study. “Protein sources with the greatest functional effects were integral rice, yeast and egg whites.” A variety of sources. Proteins are a key nutrient that gives us essential amino acids with which our body is able to synthesize its own proteins. Foods of animal origin such as meats, fish or eggs are usually seen as the main source of amino acids, but they are not the only one. The existence of alternatives implies the possibility of diverse effects on our health and well -being. Through, for example, of the microbiome. Metabolizing amino acids. The team resorted to its study to the use of high -resolution mass spectrometry and the combination of metagenomic and metaproteinomic. Everything to find how the intestinal microbiome of mice whose diet was altered so that each week they received their single source proteins that was changed after seven days .. They observed that some of these sources were associated with important changes. These changes, Explain the teamthey manifested in how the mice metabolized the amino acids, but also in the way in which their digestive system degraded complex sugars, something that was not so intuitive. Diets such as those based on the integral rice and the clearing of the eggs, continue to explain the equipment, increased the degradation of the amino acids, which would imply that the microorganisms of the digestive system of the mice were breaking the proteins to obtain their own amino acids. The details of the study were published recently In an article in The Isme Journal. An environment (too much?) Controlled. The team responsible for the study admitted That there are some limitations to consider, and one of them is the complexity of the diet. In a laboratory environment, the team altered the diet of the mice radically (causing them to have a single source of protein). Beyond the fact that studies with animal models are not always transposed identically in humans, it is expected that forceful changes in the diet of these animals entail important changes in the structure of their microbiome. A more varied diet, with diverse sources of proteins, would logically imply more dim effects.

The lack of protein represents a risk to our health. These are the key symptoms to identify it

by

We live perhaps in him historical context of greater food abundance. It is difficult to find an era in which we have had a greater variety of food at our disposal. This is especially true for meat and fish, two of the main sources of protein. In general, today We consume more proteins than we needbut the general does not always apply and The lack of protein It can also occur in some people, for example cases of certain diets or between people suffering from certain autoimmune diseases. That is why we can ask ourselves, how can we know if we are not consuming enough proteins? Proteins are one of the three macronutrients considered basic for the proper functioning of our body, the other two fats or lipids, and carbohydrates. We associate these nutrients to meatfish, milk products, but are present in one way or another (in their constituent blocks, for example) in a multitude of foods such as legumes or soy. Proteins, although we put them in the same group are not a homogeneous group of compounds: our body has thousands of protein types. Of course, all of them are composed of a series of amino acids chained 20 of these “blocks” are enough to form this myriad of proteins in our body. Our body is able to synthesize 11 of These amino acids But for the other nine, called essential amino acidswe must obtain them from food. For this we need proteins: our digestive system breaks them down in amino acids so that our body can rebuild them according to their need. We call “Complete proteins“To foods containing all essential amino acids. A list of food with complete proteins would include meats such as beef or chicken, fish, eggs, dairy, soy or quinoa. If our body does not consume enough proteins or other amino acid sources, we can fall into the lack of any of these nine essential amino acids, so that our body can lose the ability to generate its own proteins which results in problems such as the Hypooproteinemiathe lack of protein in the blood. Symptoms Before the lack of proteins becomes a problem, we can pay attention to some symptoms that alert us to lack. Health experts from the University of California in Los Angeles They prepared a time ago a list With six indications that can help us detect the lack of protein. In the article they explain that fragility in hair and nails is sometimes the first sign of a protein deficiency. Another sign is in the feeling of weakness and hunger. Hunger usually indicates the lack of food, sometimes it can also indicate a more concrete nutritional lack. A third indication is in our immune system. The lack of protein can limit our body’s ability to defend against external threats so we can find ourselves more sickly due to this lack. The lack of protein can also manifest in changes in humor or difficulties in thinking. This is due to fluctuations in blood sugar levels and the effect of proteins in brain neurotransmitters responsible for regulating our mood. The fifth indication indicated by these experts is muscle weakness. Proteins are indispensable to build and repair muscle mass, without it we can end up losing it. The last of these symptoms is in the Appearance of fractures by stress in the bones. The integrity of these also depends on this type of compounds. Proteins are fundamental to our body and the difficulty in creating new molecules can cause us problems of very diverse type. As usual in nutrition, excess can also be linked to some problems. Some estimates calculate that excessive protein consumption may appear if we take more than two grams daily per kg of body mass. A varied and healthy diet is key to avoiding problems both by excess as defaultin regards to proteins and with regard to any other nutrient. This is especially important for those who, by their own or for health, must eliminate some usual piece of their menu. No food is essential but there are nutrients that they are.

A protein that protects us from baldness

by

In recent years we have seen the rapid expansion of hair surgery as an effective way to fight hair loss, alopecia. However, we are still far from finding effective and efficient solutions, and that do not require passing through the operating room. MCL-1. Now, an international team of researchers has found a protein Linked to hair growth, a “guardian” against hair loss. The discovery opens a new route of research in the field of alopecia and capillary health. It is the MCL-1 protein, a protein belonging to the BCL-2 protein family. This group of protein performs An important role In cell apoptosis, programmed cell death. HFSC. The team detected the importance of these proteins in the functioning of the stem cells of the hair follicle or HFSC (HAIR Follicle Stem Cells). These cells regulate hair growth With its activation and inactivation. A fragile balance. Capillary growth depends on the work of these HFSC cells but also on their ability to start their apoptosis, their self -destruction, at the right time, giving way to new cells that continue their work. However, this is a fragile balance that can be broken when cell stress accelerate this scheduled death. According to the new work, MCL-1 proteins exercise a role of protectors of this balance. The absence of this unaction that includes the activation of the P53 genea sign of stress that ultimately carries cell death. In mice. The process was proven in mice. The team “deactivated” MCL-1 in these mice and then removed the animal’s hair in some areas of its skin. Thus observed the appearance of cell stress and activation of the P53 pathway. The result: the hair did not grow again. The details of the study were published In an article In the magazine Nature Communications. An upward market. Half -World Laboratories compete in the race for developing treatments that avoid hair loss. It is a career that promises a succulent prize: the hair loss industry already moves millions in surgeries and treatments capable of slow down the rhythm to which we lose hair. In addition, Ozempic’s success reminds us of the great economic potential of pharmacoesthetic. Today we have potential formulas, which include From the microarn (small RNA particles) even vaccines of messenger RNA (RNM) as those used in the fight against COVID; Going through the “cloning” of hair, a treatment that, although promising, also demands the passage through the operating room.

Protein shake glycine

The automobile industry has taken the path of electrification. Sean electric, hybrids of any type or microhíbridoseveryone has something in common: larger or smaller, they set up a battery. And that carries a long -term problem: what will happen to that battery when Finish the car’s life cycle. The answer should be recycling, but current methods emit large amounts of waste and do not allow all lithium and other battery components to recover. However, Chinese researchers believe they have found the key to recover 99.99% of the lithium of batteries. And the secret ingredient is something that is in the protein smoothies that we consume to gain muscle mass: glycine. Need. Our dependence on lithium batteries It’s worrying. Numerous devices have them as a source of energy, but in the case of electric vehicles, obviously the necessary amount is much higher. It is what has caused global production to quadruplica between 2010 and 2022. And that 2022 already said that We were going to need more lithium of which, probably, have the planet. Ok, then we recycle. The problem is that … well, there are not few problems. Recycle a battery (this applies to anyone, but intensifies with the huge batteries of cars) is that it takes a long time to perform the process. You have to download it completely before you can handle them safely and, once done that, there are two consolidated methods: Hydrometallurgy: By acids, metals dissolve in a process known as leaching. We can obtain both lithium and nickel/cobalt and it is estimated that 99% of them are suitable for new batteries. Pyometallurgy: By ovens at 1,500 degrees Celsius, the components are melted and cobalt, nickel and copper are separated, on the one hand, and the rest of the components (aluminum, lithium and manganese) on the other. To recover lithium, after pyrometallurgy you have to do a hydrometallurgy process. The inconveniences are clear: in the case of hydrometallurgy, the use of acids is very polluting and liquid waste must be managed. In addition, it takes a long time to break down and separate the elements. In that of pyrometallurgy, although the process is faster, large amounts of CO2 occur that are emitted to the atmosphere and consume a lot of energy. Glycina. It is necessary to find more sustainable alternatives, and that is where glycine comes into play. Researchers from the South Central University of Changsha, the University of Guizhou and the National Center for Advanced Materials Engineering of Advanced Energy Storage have found a way of recycling less pollutingly 99.9% of the battery materials. In his studyexpose how glycinawhich is a non -essential amino acid found in proteins, can achieve an efficient recovery of 99.99% of lithium, 96.86% of nickel, 92.35% of copper and 90.59% of the manganese of batteries. Turbohydrometallurgy. Researchers detail that the key is to create an atmosphere of soft leaching. Changing ‘hard’ acids that are commonly used in battery recycling for neutral pH solutions with glycine allows the materials of the old battery to decompose and subsequently recover the elements that interest in the face of their recycling in new equipment. As they point from Motorpasionby contacting the batteries used with an iron salt solution, sodium oxalate and liquid glycine, an iron layer is formed on them that plays the anode paper, while the battery material that is recycled works as a cathode. This chemical provides a process that breaks down the battery structure, facilitating the independent dissolution of lithium, nickel, cobalt and manganese. In addition, the team ensures that it is a quick process: just 15 minutes. Recycle vs mining. From the study they affirm that it is a cheaper process, more energy efficient and with less emissions than the traditional methods of hydrometallurgy that use acid or ammonia, but of course, it is something that has been tested in the laboratory and that would have to be seen in a real scenario. What is clear is that recycling seems the key to advancing in that automotive electrification without resorting to an increase in the Exploitation of lithium mines. A few weeks ago, researchers at Stanford University published a study in which they compared the benefits of lithium -ion batteries recycling in the face of the extraction of new materials. In summary: It is emitted between 58% and 81% less greenhouse gases. It is used between 72% and 88% less water. It is used between 77 and 89% less energy. Less soot and sulfur is also emitted. We are in it. These results are the result of a method patented by university researchers. It is like pyrometallurgy, but selectively, so the temperature is lower and emissions, therefore, they are also. Whether with the Standford method or with that of glycine devised by Chinese researchers, the world is in that race for the recycling of electric vehicle batteries. Princeton University are investigating the low temperature plasma to replace the traditional methods of pyrometallurgy; There are already companies that have BMW or Mercedes contracts with the objective of recycling car batteries and also methods that use the microwave radiation To separate the components: up to 87% of the lithium of a battery in 15 minutes. It is evident that, just as there is a career for electrification, it is also actively investigated how to reuse batteries that no longer serve for new cars, but that can be used in the manufacture of others. At least while we wait those of solid state… Images | Tennen-Gas In Xataka | The US has found lithium to solve the problem of the electric car “for decades.” It is worse news of what it seems
