We thought matcha tea was just an internet fad. Science has seen that it “hacks” our brain against allergies

He matcha tea is beginning to be a standardized drink among many people who need get up with one in your handslike those of us who need coffee to wake up. Something that has also been accompanied by the opening of a large number of establishments specialized in its production. And although for many people it may seem like a joke or an expensive fad promoted by internet gurus and people closest to Eastern countries, the truth is that it has a large number of benefits that do not stop growing. Its component. Matcha tea hides a biochemical profile that far exceeds that of conventional green teaand the key lies in how it is grown and consumed. Precisely by ingesting the whole powdered leaf, we get a very high concentration of EGCG (epigallocatechin gelato), L-theanine and caffeine. Its benefits. One of the most important is that we are facing a great antioxidantand in this way studies suggest that matcha drastically reduces oxidative stress and key inflammatory markers such as IL-6. In fact, in some trials, its ability to restore cellular homeostasis exceeds that of vitamin C. Additionally, the synergy between caffeine and L-theanine is the real productivity “trick.” Daily consumption has been shown to moderate fatigue and improve spatial learning and, in addition, upregulates the brain-derived neurotrophic factorwhich enhances memory without altering the sleep cycle. Metabolic impact. In high-fat diet models, matcha suppresses weight gain and fat accumulation in the liver. In humans, trials show better glycemic control and an improvement in the lipid profile, lowering ‘bad’ cholesterol (bad in many quotes) and raising good cholesterol. Its role in allergies. As if all this were not enough, a recent study published at the beginning of this month of March has put an unexpected finding on the table: matcha can be an ally against allergic rhinitis. Something that is welcomed with open arms right this spring where a very tough allergic season is expected. In this case, the team led by Osamu Kaminuma, from Hiroshima University, administered oral doses of matcha of 250 mg/kg to sensitized mice. The result was a significant suppression of allergen- and histamine-induced sneezing. Its mechanism. Here matcha did not alter the traditional immune system, which is the one that detects an allergen as an ‘enemy’ and wants to eliminate it at all costs. What it did was suppress neuronal activity in the brain stem, directly blocking the sneeze reflex on a neurological level. Although confirmatory trials in humans are still lacking, and it opens the door to fascinating non-pharmacological clinical use. There are several types. Not all matchas are the same, and you should always opt for the ceremonial quality grade, since it is first harvest, stone ground, bright green in color and with a large amount of antioxidants. In addition, authentic Japanese origin guarantees quality, and you should also avoid those that have been industrially processed.

We have been looking for the definitive cure of allergies for years and we have not yet solved the big problem: understand them

April 26, 2025 by usatoday24

The end of the rains and the arrival of good weather have, for many, a dark back: The allergies. Spring, and especially the months of May and June, brings us the pollen proliferationone of the most important allergens, the main cause of sneezing at this time of year. The most common way of treating this type of allergies is through antihistaminesdrugs aimed at blocking the effects of histaminea neurotransmitter that also plays an important role in immune system. Recall that allergies are nothing other than a reaction of our immune system to external substances that understands as dangerous and that are not really, allergens. Antihistamines are very useful when treating allergic symptoms. But one thing is that, and another thing is to definitively cure these disorders. Today we do not have A cure for allergiesbut at least there are some routes open to hope. So close we are to achieve it. Perhaps one of the first treatments that come to mind when talking about healing the allergy are vaccines. What we understand today as vaccines against allergy are immunotherapy -based injections, and its logic is not far from conventional vaccines: it is about administering a small amount of what causes us allergy capable of alerting the immune system without unleashing an allergic reaction. While they are a useful treatment in many cases, they do not finish solving the problem, so we will need periodic injections that will improve the response capacity of our immune system. What ways are there open? Almost ten years ago, We commented on some of the open research lines in the search for a cure for allergies. These ways included, for example, the “biological therapies.” These are therapies that focus on antibodiesthe proteins that our body produces when it detects substances that it understands as harmful. This type of treatments They are still One of our great hopes. An example of this is omalizumab, a drug in principle aimed at combating asthma and approved two decades ago in the United States. In recent years, science has been validating this therapeutua option. A recent example is in A study Posted in 2022 in the magazine Clinical and Translational Allergy. In this analysis, the team observed that the drug was effective when preventing spring allergic rhinitis. Understand the problem To understand how our knowledge has evolved in recent years, we must first understand why it is so difficult to find a definitive cure. The background problem is simple: We do not understand the allergies well enough to find a solution. We still do not understand why certain people suffer from a certain allergy while others suffer from another type of reaction, at the same time that others do not seem to have such problems. We don’t know either Why allergies are permanent despite the fact that the antibody that we generally associate with them does not usually remain in our body for long periods of time. Two studies Published last year in the magazine Translational Medicine Science They can help us understand this situation a little better, explaining at least this last point. The answer could be in an antibody that we usually do not associate with allergies, immunoglobulin G (IgG), and the cells that produce it. What the teams responsible for these studies discovered is that some cells responsible for producing IgG produce immunoglobulin E, which is associated with allergies, when they run into an allergen. The key to allergic “memory” could therefore be in these cells. Before going better, everything seems to indicate that the allergies problem will go worse. And is that every time More people suffer This type of disorders. There are several factors that could be, independently or together, behind rapid ascent in the number of allergic people in the world. One of these hypotheses is that of hygiene. Since our immune system is “trains” through exposure to external agents, the absence of these agents in early stages can imply that our system does not perceive them as normal and, exposed in later stages, ends up reacting disproportionately. s From the environmental point of view, we must also consider the presence of pollutants in the atmospherelike particular matter. These pollutants can also affect our airways, combining their effect with that of conventional allergens and aggravating the situation.
