Higher vitamin A level promotes fat burning – naturopathy & naturopathic specialist portal

Vitamin A stimulates fat burning in the cold

Vitamin A is one of the fat-soluble vitamins. Among other things, it is important for cell growth, the function of the immune system, the visual process as well as the health of the skin and mucous membranes. And it could help in weight loss. Because according to researchers, vitamin A boosts fat burning during the cold.

According to a recent announcement, a new study by a research team from the Medical University (MedUni) Vienna shows that cold ambient temperatures raise vitamin A levels in humans and mice. As a result, there is a conversion of white into brown adipose tissue, which stimulates fat burning and heat production. This “fat transformation” goes hand in hand with increased energy consumption and is therefore considered to be a very promising approach in the treatment of obesity.

New therapeutic option against obesity

In humans and mammals, a distinction is generally made between at least two different types of fat deposits, white and brown adipose tissue. The white adipose tissue is much more common in the human body, stores fat and is preferably located on the abdomen, buttocks and thighs.

The body can fall back on these deposits when it needs more energy. Brown fat, on the other hand, burns energy while releasing heat. However, with age and overweight, the number of brown fat cells decreases, which is why the possibility of converting white to brown fat could be a new therapeutic option for overweight and obesity (obesity).

Converting white to brown fat

A research group led by Florian Kiefer from the Department of Endocrinology and Metabolism, University Clinic for Internal Medicine III at MedUni Vienna, has now demonstrated in a study that moderate use of cold leads to an increase in vitamin A and its blood transporter, the “Retinol-binding protein” came on.

More than ninety percent of the vitamin A reserves are stored in the liver, whereby the cold should support a redistribution of vitamin A in the adipose tissue. According to the information, the application of cold also led to a conversion of white to brown fat (“browning”) with increased fat burning. The study, in which researchers from the USA were also involved, was recently published in the specialist journal “Molecular Metabolism”.

Increased metabolic activity

When the scientists blocked the vitamin A transporter “retinol-binding protein” by genetic manipulation, both the increase in vitamin A caused by the cold and the “browning” of white fat were inhibited: “The result was a decrease in heat production and fat burning, so that the mice could no longer adequately protect themselves against the cold, ”explains Kiefer. The addition of vitamin A in human white fat cells, on the other hand, led to a development of brown fat cell properties with increased metabolic activity and energy burning.

“Our results show that vitamin A plays an important role in the function of adipose tissue and has an influence on energy metabolism. That does not mean, however, that you should simply consume vitamin A supplements unrestrainedly, since the most important thing is that it is transported to the right cells at the right time, ”explains the MedUni Vienna researcher. “We discovered a new mechanism by which vitamin A intervenes in heat production and stimulates fat burning during the cold. This could help us to develop therapeutic interventions in the future that use precisely this mechanism. “(Ad)

Doctors have named vitamins that will help to survive the winter

The doctors told us what vitamins should be taken in the autumn-winter period in order to survive the winter without colds and viral diseases.

The most important vitamin in winter is vitamin D.

According to the doctors, fat-soluble vitamin D is necessary not only for raising immunity, but also for a good mood.

As you know, vitamin D is called “sunshine” because it is produced by our skin when exposed to UV rays.

For its production, the skin needs sunlight, and, as you know, in winter we feel worse due to a lack of sunlight.

With a lack of this vitamin in the body, mood worsens, energy is lost.

Vitamin D can be taken in capsules, or you can get it from food. It is found in fish and lard.

Vitamins A and C are also important to consume during winter. They are found in carrots, citrus fruits, herbs, liver, vegetables.

Explore foods that are rich in B vitamins and magnesium.

They are very involved in the synthesis of hormones that are responsible for mood.

With a lack of these vitamins, a person has a hard time waking up in the morning, experiencing stress and anxiety.

Severe cold from unwashed masks? Doctor explains whether this is really possible

Discussion about colds on Reddit

A user in the online forum Reddit announced that he had various people in his environment who had bad colds. According to his family doctor, this is due to wearing unwashed respiratory masks in everyday life. We have medical professionals Dr. Christoph Specht asked if that was really true.

Doctor explains: important difference between viruses and bacteria

The explanation that breathing through unwashed respiratory protection masks can make colds worse appears logical at first glance – but it is not true. Dr. Christoph Specht explains: “Most colds are virus-related and are not based on bacteria. Bacteria can grow on surfaces, viruses cannot. Viruses need other cells to infect them and there they multiply.”

This is the crucial difference: While bacteria can multiply on a mask through expelled air, viruses would land on the mask, but could not grow further there.

In addition, we cannot infect ourselves. “You don’t get infected by yourself. The viruses were already from you, which means your body has to deal with them all the time,” explains Dr. Woodpecker. “Still, it’s important to wash the masks regularly. Bacterial colds are unlikely because most colds are virus-based.”

Winter tires: everything you need to know before fines are triggered

14 October 2020 – 18:25

With the arrival of the cold and the first snows, the obligation to use devices suitable for the season returns: M + S tires fitted or chains in the trunk. The rules, the dates, the risks …

of Renato Dainotto

In some areas of northern Italy winter has already arrived and snow has even been seen. On 15 November, the obligation to circulate with snow tires (those marked M + S) mounted or chains (in the trunk, ready to be mounted in case of need) on most of the Italian road and motorway network in the North begins. , Central and Southern Italy. The obligation will remain in force until April 14th. From 15 October you can change: off the summer tires, on the winter ones. do not waste time, because November 15th seems far away but the crowding of tire dealers’ appointments risks dragging beyond that limit. For those who travel only in the city, waiting is not a serious problem, but those who move every day (such as those who have a second home in the mountains) cannot fail to be found in good standing as soon as the hour X. as well as – primarily – with safety, he will have to deal with the Polstrada. Whoever is found without snow tires or without chains on board or with chains of different sizes from that of the tires – therefore useless – gets a fine: the infringement outside inhabited centers ranges from 84 euros to 334 in the most serious cases, and in addition there is a 3-point deduction from the driving license. In built-up areas, however, the fine starts at 41 euros. Not only that: if the snowfall is serious, the order may have to force you to park and walk …

Perm doctors told how to distinguish ARVI symptoms from coronavirus and flu. Despite the fact that they are very similar, there are still differences. So, for example, the incubation period for coronavirus can last more than two weeks.

The symptoms of the Covid-19 coronavirus are similar to those of pneumonia or severe acute respiratory syndrome:

Loss of consciousness (as a result of progressive destruction of lung tissue)

Dry, unproductive cough

Fever and fever (38 ° C or higher, chills)

Difficulty breathing

Chest pain

Headache,

Muscle pain,

General malaise.

Mild form of coronavirus COVID-19

Mild fever, mild headache, increased fatigue, sore throat, coughing, muscle aches, mild signs of a cold, pallor, chills. Rarely runny nose.

How not to confuse the symptoms of coronavirus COVID-19 with SARS

With SARS and colds, unlike COVID-19, the cough is wet, not dry, and there is always a stuffy nose and a runny nose. Similar symptoms include a slight fever and mild to moderate headache.

How not to confuse the symptoms of the coronavirus COVID-19 with the flu

Rospotrebnadzor, based on information from WHO, reports on its website that the symptoms of COVID-19 and influenza are similar: “both cause respiratory illness with a wide range of options – from asymptomatic or mild to severe illness and death.” But with the flu, there is no shortness of breath or other breathing problems, and the temperature is almost always high, unlike COVID-19.

As every autumn, the viruses that cause colds and, shortly, the first gripes. This season they will also coexist with him Covid-19. To prevent these three types of respiratory infections, the guidelines to follow are the same:

– Frequent hand washing, especially important after going to the bathroom or changing diapers, before eating, after touching animals, collecting their feces or cleaning them; when cooking or handling food, after touching land, before touching a newborn, an elderly person or a sick person, after traveling by public transport.

-When we cough or sneeze it is better covering your mouth and nose with your arm or a tissue (They must be thrown away after each use, do not keep them used or leave them on tables or tables!) instead of by hand.

-Avoid effusive displays of affection such as kisses.

-Neither should you share glasses, cutlery, towels and other objects that may have been in contact with saliva or secretions.

-In closed houses and establishments, ventilate often.

-Use of approved masks and social distance.

-In the case of the flu, and if you belong to one of the groups indicated by the Ministry of Health, get vaccinated against the flu.

-Keep the immune system in the best possible conditions to protect ourselves from infections. Here we tell you how to increase your defenses naturally.

Can the common cold protect you from the coronavirus?

ABC Health

Updated:

save

The colds Fall and winter are uncomfortable, but they may have their good side. New research, carried out by experts in infectious diseases from the University of Rochester Medical Center, suggests that colds you have had in the past may provide some protection against Covid-19. The same study also suggests that immunity to the coronavirus is likely to last a long time, perhaps even a lifetime.

The trial, published in “mBio”, is the first to show that the virus that causes Covid-19, SARS-CoV-2, induces memory B cellslong-lasting, immune cells that detect pathogens, create antibodies to destroy and remember them in the future. So the next time the pathogen tries to enter the body, those memory B cells can spring into action even faster to clear the infection before it starts.

Because memory B cells can survive for decades, they could protect patients who have overcome Covid-19 from subsequent infections for a long time, but more research will be needed to confirm this.

The study is also the first to report the cross-reactivity of memory B cells. This means that B cells that once attacked cold-causing coronaviruses appeared to recognize SARS-CoV-2 as well. The study authors believe this could mean that anyone who has been infected by a common coronavirus, which is almost everyone, can have some degree of immunity preexisting against Covid-19.

‘When we looked at blood samples from people who were recovering from Covid-19, it appeared that many of them had a pre-existing set of memory B cells that could recognize SARS-CoV-2 and rapidly produce antibodies they could attack it, “says Dr. Mark Sangster, research professor of Microbiology and Immunology at URMC and lead author of the study.

Sangster’s findings are based on a comparison of blood samples from 26 people who were recovering from mild to moderate Covid-19 and 21 healthy donors whose samples were collected six to 10 years ago, long before they could have been exposed. to Covid-19. From those samples, the study authors measured the levels of memory B cells and antibodies that target specific parts of the body. Spike protein, present in all coronaviruses and that is crucial to help viruses infect cells.

The Spike protein looks and acts slightly different in each coronavirus, but one of its components, the S2 subunit, remains largely the same in all viruses. Memory B cells cannot differentiate between the Spike S2 ​​subunits of different coronaviruses and attack indiscriminately. At least the study found that to be true for betacoronaviruses, a subclass that includes two viruses that cause colds, as well as SARS, MERS, and SARS-CoV-2.

What this study not shown is the level of protection provided by B cells cross-reaction memory and how it affects patient outcomes.

“That’s the next thing,” says Dr. David Topham, professor of microbiology and immunology at URMC, and director of the laboratory that conducted this work. “Now we need to see if having this set of pre-existing memory B cells correlates with milder symptoms and a shorter course of the disease, or if it helps increase the effectiveness of Covid-19 vaccines,” he advances.
