Green tea has always been thought to be good for losing fat. Now we know why

by

Green tea has been known for centuries for its antioxidant properties and medicinal, and modern science has therefore wanted to investigate whether it really has clear effects on metabolic diseases important such as diabetes or obesity. Now, a new study published in Cell wanted to delve deeper into its mechanisms and reveals that green tea significantly improves glucose sensitivity in obese mice. The diet. To reach these conclusions, the research team put mice on a high-fat diet for four weeks to induce obesity. After this time, they divided the animals: one group continued with the high-fat diet and received a standardized green tea extract (500 mg per kg of body weight), while another group received only water. A third control group consumed a normal diet for comparison. The temperature. The key to the study, and what differentiates it from many others, was temperature control. Mice were maintained in a “thermoneutrality” environment at 28°C. This is crucial because the usual laboratory temperature (about 22 °C) means cold stress for the mice, which forces them to spend more energy to stay warm and therefore lose ‘artificial’ weight. This extra energy expenditure can mask the true effects of the substance studied, such as green tea in this case. In this way, by eliminating this factor, scientists were able to “cleanly” observe the real impact of green tea. The result. They confirmed the powerful effect of green tea on weight control and metabolic health. According to a previous study by the same group, obese mice treated with green tea reduced their body weight by up to 30%, a very significant result. In the current research, it was noted that the treatment “effectively prevented body weight gain.” But in addition to the weight, which can be very good, the most interesting thing is undoubtedly the ability of green tea to make the body better manage blood sugar. Obese mice treated with the extract were seen to restore their glucose levels to levels similar to those of healthy mice, as demonstrated by glucose and insulin tolerance tests (GTT and ITT). Although if you look at the fasting values ​​there are also important changes, since the treated mice had lower sugar values ​​than the obese mice that were not treated. Protective effect. One of the most notable findings was the effect protector on muscle mass. Obesity usually causes a reduction in the diameter of muscle fibers (atrophy), but the study revealed that green tea not only prevented this deterioration, but caused a “significant increase in the cross-sectional area of ​​muscle fibers.” This suggests that green tea protects muscle from the harmful effects of obesity. The mechanism. There are several systems to understand why these effects occur in the body: Fat metabolism: treatment increases the expression of key genes involved in lipid uptake in the muscles, and the creation of new mitochondria is also enhanced, which in the end are the ones that will use up the energy. Glucose uptake: sugar uptake was improved by improving the number of insulin receptors in cells as well as the famous transporter GLUT4 which allows the muscles to capture and use this sugar much better by removing it from the bloodstream. Energy production: increasing the enzyme LDH in the body it is related to an increase in energy metabolism that increased in treated mice. It’s not a miracle. Although the results are promising, researcher Rosemari Otton warns that this is not a miracle solution. The dose used in mice would be equivalent to about three cups of green tea a day for a human, but quality is essential. Otton recommends the use of standardized extracts, since the tea bags we have in the supermarket do not always guarantee the quantity or quality of the flavonoids, which in the end are the beneficial compounds.

This is how coffee and green tea have sneaked into the list of allies

by

Before looking at the mobile, before speaking with anyone, there is an almost sacred gesture: prepare coffee. Beyond frightening sleep, that cup could have an unexpected benefit to your health: protect your liver. An invisible enemy. More and more people live with a diagnosis that usually goes unnoticed for years: the fatty liver. A disease that in Spain affects one in four adults, According to the Spanish Association for the Study of the Liver (AEEH). Can’t it be detected before? The point is that the liver accumulates fat silently. At first it does not hurt, it does not bother and does not warn. Only when it advances already becomes more serious problems such as fibrosis, cirrhosis or liver cancer. The accumulation can should be mainly two causes: Alcoholic liver disease, linked to alcohol consumption, or metabolic hepatic stanosis (EHMET or MASLD), related to obesity, insulin resistance and metabolic alterations. And a key actor in the equation: sugar, especially the fructose added in sodas, pastries or ultraprocess cereals. Unlike glucose, fructose is almost exclusively metabolized in the liver, which triggers fat manufacturing. An unexpected ally. Among the classic recommendations – e -evident simple sugars, trans and alcohol fats – science has begun to look at coffee. According to Dr. Javier Escalada, Endocrinologist and director of the Department of Endocrinology and Nutrition of the University of Navarra Clinic, This has explained it for Hola magazine: “Coffee is not only safe, but its consumption is associated with less risk of progression of liver damage. It can even reduce transaminases and protect against hepatecellular carcinoma.” Different studies, collected by Cleveland Clinicthey also demonstrate that coffee helps reduce inflammation and prevents the accumulation of fat in the liver thanks to its antioxidants. As Dr. Jamile Wakim-Fleming pointed out to the same medium, a process called autophagy is activated, a kind of internal cleaning that eliminates damaged cells and protects the organ against fibrosis. Another type of allied cup. In parallel, green tea is also consolidated as another ally. Its catechins and antioxidants help reduce liver fat, improve the lipid profile and exert an anti -inflammatory effect. The evidence is more solid in green tea than in black or red. Of course, with an important nuance: the benefits are observed in traditional infusion, not in extracts concentrated in capsules, which in high doses can damage the liver. A great population study in the Netherlands, Published by Journal of Hepatologyanalyzed more than 2,400 people and found that those who took three or more coffee cups a day had less liver rigidity – a fibrosis indicator – against those who did not consume it. The effect was also observed in herbal infusions consumers. Although not everything depends on a cup. It should be put in context. Neither coffee nor green tea are a magical potion. They work, but within a healthy lifestyle. Doctors insist that the basis of fatty liver treatment is to change the lifestyle. That means following a Mediterranean diet, exercising, no alcohol or tobacco, dominating well and controlling stress. As the nutritionist Isabel Higuera has detailed To the Spanish magazine: “The diet set is more important than food in isolation. In these patients it is key to consume enough fiber, healthy lean proteins and fats, but always adapted to each person.” Beyond the cup. The fatty liver does not warn, but it is not an inevitable destination either. There is no miraculous remedy, although science suggests that small daily habits can make a difference. Among them, something as simple as coffee or green tea, which not only clear the dream, also seem to protect the liver. A reminder that health begins in gestures as simple as what we eat, drink and repeat every day.

If the question is “how much caffeine each cup of coffee or tea has”, this graph offers revealing responses

by

Every day, the world consumes about 2,250 million coffee cups. Let’s drink for their Health effectsbut also for its flavor and for caffeine. This substance surrounded by myths It is the psychoactive more consumed and is present in a lot of products outside coffee such as tea, sodas or energy drinks. Now, not all caffeine drinks have the same amount, and in this graph we can see how much caffeine your favorite coffee or infusion has, with an incontestable winner: the espresso. But there are many nuances. The figures. There are many ways to prepare coffee. In the Italian classic, With filterpercolation, infusion and even with unthinkable supplements until not as much as Protein either Fungi. And the amount of caffeine of each elaboration depends both on the caffeine of the grains of each variety of coffee, its roasted process and the way of cooking it. Caffeine for 30 ml of drink Espresso coffee 62.5 mg Filter coffee 22 mg infused coffee 17 mg Coffee for percolation 15 mg Matcha 8.75 mg mate 4-6 mg Black or green 4-6 mg Instantaneous 1.9 mg MILK CHOCOLATE 1 mg Decaffeinated instant coffee 0.6 mg Very roasted coffee decaffeinated 0.4 mg As the graphic prepared by Visual Capitalist With studies data from Health Canada and Consumer Reportscoffee with a greater concentration of caffeine is the espresso. As much, in addition: in 30 milliliters of drink, it has almost four times more caffeine than the following elaboration, and twelve times more than a black tea. The rest of coffee elaborations are quite pair, but we continue to see a greater concentration of caffeine than in the Matcha tea so popular latelyin the mate or in other tea infusions. If the Italians already knew … That the espresso has the greatest concentration is not a surprise and, in fact, it is an essential part of this elaboration. In it, by the extraction method itself, both flavor and intensity are intensified, increasing that concentration of caffeine. And it is something with a practical function. In the Italian traditionthe espresso was born to be fast. The coffee had to be extracted in the shortest possible time, standing at the bar of the bar and continuing with the day. Traditionally, it is taken without milk, as if it were a sucking sucking that is rapidly sipping, implying a break on the workers’ day, but also that energy ‘chute’ thanks to caffeine. It is a more practical drink than anything else, or it was. The ‘deception’. But of course, we must bear in mind that there is a very important factor in these data: The size of the cup. 30 milliliters is scarce, and it is the amount of an espresso. The coffee size that is usually taken is much larger, so it ends up compensating for the lower concentration of caffeine in other elaborations. An example is the Cold Brew, which is a Perfect infusion for summer that we take in a long glass of more than 300 milliliters. Adding the quantity and long extraction times, the caffeine goes to 200-280 mg per cup. The filtered coffee is also taken in high volumes, contributing between 95 and 150 mg per cup, and something similar occurs with the French press and its contribution of between 80 and 100 mg of caffeine. If we talk per liter, Newcastle University He found That the espresso is the absolute queen, but in the amount of drink we can take, the easiest thing is that there are many elaborations that exceed that contribution of the espresso. Caffeine per liter Espresso 4,200 mg Cold Brew 2,240 mg Moka 2,192 mg French press 742 mg Drip 692 mg How much caffeine is a lot of caffeine. And although there are more and more studies that suggest that caffeine is not a problem nor is it cause of heart attacksa question that is still on the table is how much coffee is too coffee. A study by the European Food Security Authority revealed that the unique doses of 200 mg are not any problem and that a maximum of 400 mg for an adult is fine. In pregnant women and infants, the thing changes and the figures are reduced, but the general measure is about 5.7 mg/kg of the person to talk about safe amounts. But, as we said, it is something that depends a lot because not only does the elaboration come into play, but The origin, variety and roasted of coffeesince it is something that vary the amount of caffeine in the final elaboration. And that is good or not so healthy depends a lot on the situation, such as If dream is missing or if we are going to do some sport.

The world wants more and more matcha tea. The problem is that Japan is not being able to give it to him

by

For centuries Matcha tea It has been one of the most recognizable symbols of Japanese culture. Now is that and something else: a drink popularized by social networks and coveted in the international market to such an extent that, in Japan itself, there are stores that have been forced to limit sales by customer. The world is thirsty for Matcha. Increasingly. And that has triggered a deep imbalance in the market that will not be easy to correct in the short term. The big question is … why? Limited purchases. The market of Matchaa popular Japanese powder tea that is made with Técha leaves And it stands out for its bright green color, faces a complicated scenario: a considerable (and growing) decoupling between the supply and demand that has even led some suppliers to limit the amount of product they sell to their customers. Recently Nikkei Asia He spoke of online stores without stock or UJI and Kyoto stores in which only a single Matcha product per day is allowed to acquire. Nothing else. “Due to the strong and continuous increase in the demand for products in recent months, the current demand has already exceeded our production capacity,” Recognize The store Marukyu Koyamaen In a message posted on its website. “This translates into an extremely low inventory of all Matcha products at this time.” If the scenario were not complex in itself, it is added that there are producers who want to prevent their historical clients, such as temples, sanctuaries and places where the drink is used for ceremonial purposes, they are left short. A figure: 4,176 tons. The figures always help to better understand trends. And that of the Matcha boom is no exception. Although throughout the last decades the consumption of green tea and Matcha has been losing bellows in Japan, its success among foreign consumers has triggered the production of the ground TE. If in 2010 the country produced 1,471 tonsin 2023, according to the data of the Ministry of Japanese Agriculture (Maff), that volume had shot up to the 4,176 tons. Almost triple. The Japan Times Precise In addition, in the last five years, the sector has experienced a key change, orient more and more towards the international market: today more than half of the Japanese matcha ends up exporting. In general Nikkei Calculate That last year the flow of green tea exports reached 8,798 tons, ten times more than a couple of decades ago. Of that volume, powder tea, especially Matcha, represented more than half. The reflection in prices. The increase in demand has not long to move to prices, which draw an upward curve. After years down, the value of the tancha began to rebound after the pandemic and It has been consolidating little by little. In early May the Japanese newspaper The Asashi Shimbun revealed That, in the first auction of the year of green tea held at the Ja Zen-Noh Kyoto distribution center, the kilo reached an average of 8,235 yen, almost 67 dollars and 1.7 times more than a year ago. The value far exceeds the previous record, of 2016. Looking out of Japan. Interestingly, matcha fever comes after decades in which both the consumption of powdered tea and green tea in general has been losing strength In Japan’s households, which also explains that has decreased production. The causes of their renewed boom must be sought beyond, in an international demand that According to some analysts It moves to historical maximums. Only American buyers absorbed in 2024 44% of shipments International TEA powder. Second, quite a distance, Germany and Malaysia are. There are estimates that calculate that Matcha’s world market will be around 5,000 million of dollars in 2028, a more than considerable amount if one takes into account that in 2023 it stood at 2.8 billion. “In spite He recounts in Bloomberg K. Oanh ha. What is that boom? There is not a single factor that explains the growing world thirst for Matcha. When analyzing the phenomenon, analysts usually point out a key: the visibility it has reached in networks, both for its photogenic bright green hue and by the videos and comments that extol their health benefits, a message that seems to have penetrated above all After the pandemic. To that growing interest are added the changes in the consumption of the Matcha, which has ceased to be an exclusive drink of homemade ceremonies and meetings to join bottled drinks or even accompany chocolates and ice cream. And why not grow anymore? The tancha production has grown over the last years, expanding beyond the traditional areas of Japan. In addition, their farmers have seen how new competitors from China and South Korea arrived. So … why not that mismatch between supply and demand is not remedied? The key is in the limitations that the sector itself is found to expand its crops. The country has land, but plantations are not created overnight. It takes years In being lists and tancha leaves need to pass a storage and processing phase. Especially if farmers want to wear stone mills. The sector is not alien to the shortage of collectors and the lack of generational relief in a country that dealt with a serious birth crisis. Either to A record tourism flow that further tense demand. With that backdrop, farmers also face a fear that complicates the investments in the plantations: that the Matcha boom stays alone in that, a punctual fashion.

We have been studying chocolate and tea compounds for more than 75 years. Now we know that they help control blood pressure

by

A well -known Anglo -Saxon saying that an apple per day keeps doctors at bay. The nutrients of these fruits are undoubtedly a good way to prevent in the field of health. However, the healthy compounds we find in fruits such as apple or grapes are not their exclusive heritage of these. Some can also find them in tastier foods such as tea or chocolate. Flavanoles This is the case of the flavanoles (or flavan-3-tools), some compounds that, as a study has just verified, They can help us to keep our blood pressure under control. The study suggests that foods rich in these compounds, such as tea, chocolate, and fruits such as apple and grapes can help us reduce our blood pressure and with it our cardiovascular health. “The findings are hopeful for those who seek accessible ways to manage their blood pressure and support their cardiac health through enjoyable changes. Incorporating small amounts of foods commonly consumed, such as tea, apples, dark chocolate, or cocoa powder in a balanced diet can provide beneficial amounts of flavan-3-tools,” stood out in a press release Christian Heiss, co -author of the study. This last point is important, a balanced diet is always key when taking the nutritional advantages of any food. As Heiss himself clarifies, this type of dietary changes never serve as replacement for drugs, interventions and treatments prescribed by health professionals. These foods can be considered as an additional source of Flavanoles, but it may not be the main one. Old acquaintances. Flavanoles are old acquaintances for nutrition experts. These compounds are related to the color of some foods of plant origin, but throughout the last decades we have been detecting possible benefits of these compounds in people’s health. A decade ago, for example, it was observed Thanks to a study with mice that these compounds could delay the progression of type 2 diabetes. Other studies They have detected a positive effect of these compounds About memorythat It could be mediated for its positive effect on blood circulation. 75 years of research. The new study Show the results of a review of scientific and subsequent meta -analysis literature. The team compiled randomized essays published between 1946 and 2024, in which the effects on the blood pressure of rich foods in flanks and supplements of these compounds were tested. From these analyzes, the team concluded that foods rich in Flavenoles “considerably” high blood pressure, which supports its use in cardiovascular prevention. These foods “should be considered as effective components of interventions (based on healthy habits) to reduce blood pressure and cardiovascular prevention,” The team points out. The details of the study have been published In an article In the magazine European Journal of Preventive Cardiology. A grain of sand. Nutrition is a complex science and that is why we must take into account very different considerations. For example, that a food is rich in a certain compound does not always mean that its consumption will allow us to reach the amounts that we require from the nutrient. It is also important to know if there are other nutrients or compounds that may affect us. For example, both black chocolate and milk chocolate can contribute to us Flavenoles, but the second probably also gives us excessive amounts of sugar that counteract the positive impact of these compounds.
