A team of researchers from Queen's University discovered the reason why garlic is so good for our health. Many researchers believe that the organic compound Allicin - the substance that gives garlic its characteristic smell and taste - acts as the best antioxidant known. However, until now it was not known how this substance works compared to more well-known antioxidants such as vitamin E and coenzyme Q10, which inhibit the destructive effects of free radicals.

"We did not understand how garlic is able to contain such an effective antioxidant, since it does not contain a significant amount of compounds that are usually responsible for high antioxidant activity in plants, such as flavonoids (flavanoids) found in green tea or grapes," explains chemistry professor Derek Pratt, who led the study. "If indeed allicin is the substance responsible for this activity in garlic, we wanted to know how it works."

The research team examined the substance's effective ability to trap harmful radicals, and considered the possibility that it is actually a breakdown product of allicin that is truly responsible for this activity. Through experiments with synthetic allicin, they found that acid, obtained by rapid decomposition of the substance, is the one that reacts with the radicals. Their findings were published in the January issue of the scientific journal Angewandte Chemie.

"Basically, the allicin compound needs to break down in order for the effective antioxidant to be formed," explains the researcher. "The reaction between the sulfenic acid (sulfenic acid) and the radicals is extremely fast and limited only by the time required for the two compounds to combine with each other. No one has ever observed compounds, natural or neutral, that react so quickly as antioxidants."

The researchers are sure that there is a connection between the activity of the sulfonic acid and the health benefits of garlic. "Although garlic has long been used as a medicinal plant for many generations and there are many supplements of it on the market, to date no convincing explanation has been found as to why garlic is so good for health," says the chief researcher. "I think we have taken the first step in uncovering the basic chemical mechanism that could explain the health benefits of garlic."

Garlic, along with onions, leeks and shallots, is part of the Alliaceae family. All of these other vegetables contain a compound very similar to allicin, but do not have the same medicinal properties. The researchers believe that this is due to a lower rate of breakdown of the allicin-like compound in these vegetables, which results in a lower concentration of the sulfonic acid available to react with the radicals as antioxidants.

  1. People make excuses, what's going on? Shum is just like us - he also has feelings, how can you talk about him like that?! Very unsightly, this is a violation of the right to a good name that stems from the right to respect. Such blatant behavior cannot be allowed! I recommend you apologize to him and pray for his forgiveness.

  2. From the studies I've read, garlic has not been proven to be effective.
    It is known to have a minor effect on lowering blood pressure, other than that nothing has been proven.
    The only thing that has been proven beyond any doubt is that garlic is a delicious thing.

    It is also considered better than antibiotics - it is good against the germs of the hoylam houses
    There are simply no antibiotics on the market - for the new germs found in hospitals
    And the garlic can do the same job of that antibiotic that does not exist yet

  5. I am 36 years old and I have cholesterol. I wanted to know if garlic helps it. And how do you eat the garlic raw or cooked. Thanks...

  8. Reuven
    Regarding the method: This may be the only way to enjoy all the benefits of garlic, however, it is advisable to remember that the seed of garlic (the green nozzle) is very bitter, and is not recommended for eating directly (although it can probably be used as a seasoning for food or alternatively as a basis for some medicine).

  9. Friends, I have been eating garlic for many years and thank God and garlic I am very healthy in Israel. But it must be remembered that garlic has the same healthy component in the form of gas. The best way to enjoy the benefits of garlic is: as few cuts as possible and preferably to swallow. Regarding the smell your wife complains about, I told her that garlic sculpts the butt...and since then she has been my faithful partner in eating garlic.

  10. I am sick several times a year with a strong flu and I fear an inflammation of the scrotum when Danners stopped working and I was always prescribed antibiotics for 3 weeks each time with a very strong cough. In the last two years I have used several teeth
    Garlic a day without the need for medicine Garlic with lemon and warm water and it cured me completely and shortened my days of illness which was three weeks almost with a non-stop cough became three days. garlic honey and lemon by the way I am a very very aesthetic woman and for health we do everything without the need for drugs that are no longer effective and harmful

  11. This is actually a question that interests me a lot
    I prepare an alcoholic garlic extract for myself. When I use Israeli garlic, the color of the extract is white. When I use Chinese garlic, the color of the extract is green.
    Does anyone know what the cause is?

  13. Lemon is the best medicine against the smell of garlic, lemon in any way, I drink a lot of lemon, and I can't stand the smell of garlic

  14. Hello. I'm Vika, 14 years old, from Tanya, but that's not what's important now. What's important is that I barely understood anything. I understood that garlic is healthy and everything, but I didn't understand if garlic can also be unhealthy. Is that true? Or is he always healthy? Is there a limit to the amount you can eat for say one day? And can it be dangerous, let's say if... there is an allergy to something it contains. And after eating garlic do you sweat more? Is there anything healthier than it? Does onion have the same effect? If I eat garlic with bread is it not harmful or does it reduce the effect? Should the garlic be chewed well in the mouth before swallowing or is it not important?

  15. I would like to refer first to the amount of garlic that is allowed to be eaten - as a child I liked to eat garlic, like others enjoy eating sweets, I ate unlimited garlic, sometimes a whole head of garlic and sometimes two, it did me no harm. Today - in my adulthood I definitely do eat garlic, and adjust the time of eating so that those around me do not suffer from the smell. I also use garlic for external use - sore throat, bronchitis... And I also used it to "eradicate" a fungus that no ointment helped against and also to treat an inflamed wound, whose inflammation began to spread in a really scary way, I consulted with specialist doctors and tried all the existing antibiotic ointments, nothing helped, until - until I crushed garlic and put a pad on the wound with Crushed garlic…. Within a day a significant benefit was seen, and after about two or three days the wound was healed, unbelievable

  16. Peace,
    I am 22 years old and have suffered from streptococci in my throat since I was young. This week I had a cold with a fever and a sore throat. On the first day I ate six cloves of crushed garlic and the next day another four cloves of garlic. I have no problem with the smell and will do everything to avoid taking antibiotics. I noticed that immediately after eating the garlic the pus in the tonsils shrinks significantly and the pain is less. I just wanted to know if there is a limit on the amount of garlic cloves eaten per day?
    Thank you for your quick reply!

  17. If we go one step further and apply crushed garlic on the face (with some frequency, but not too much so as not to burn), will the "sulfonic acid available to react with the radicals as antioxidants" slow down the rate of skin aging and even smooth out wrinkles and encourage the growth of skin cells new?

  18. Did you know that garlic is only mentioned once in the Bible?!!!!

    Garlic and onion are mentioned in the Bible only once, as one of the foods that the Israelites remember when they want to return to Egypt: "We remembered the fish that we ate in Egypt for free, the zucchini and the zucchini and the hay and the onions and the Sumyim" (Bamadbar XNUMX).

    Chazal enumerated several good qualities of garlic: "He satisfies, emaciates, and brightens the face and multiplies the seed and kills the honest ones in the bowels of the XNUMX. He brings in love and takes out jealousy" (Baba Kama XNUMX, XNUMX). In the Jerusalem Talmud it is written about Ezra the writer that "he decreed that garlic should be eaten on Shabbat nights because it brings in love and brings out lust" (Yerushalmi, Tractate Megillah PXNUMX XNUMXa), and it also appears from other sources that garlic became the special food for the Shabbat night meal.

    Garlic became such a distinct food for the Jews, that in the Mishnah it is stated that whoever uses the phrase "garlic eaters", he is referring to the Jews (Tract of Nadar XNUMX:XNUMX). The eating of garlic among the Jews is particularly noticeable compared to the abhorrence of garlic among the Romans.

    The strong smell of garlic served as the basis for a phrase that appears in the Babylonian Talmud several times: "Whoever ate garlic and its smell wafted away, will he go back and eat another garlic and its smell wafted away?" (Tract of Blessings XNUMX:XNUMX; Tract Shabbat XNUMX:XNUMX), the parable is: He who has sinned once, should not sin again, even though his condition now is not good. There is also a story in the Gemara in which it is told about the smell of garlic that interfered with studying in the Beit Midrash to such an extent that Rabbi Yehuda the Hanasi asked that the garlic be removed (Sanhedrin tractate XNUMX:XNUMX).

  19. Well done for this wonderful article Dr. Moshe Nachmani.
    Indeed, garlic is really not a good thing, from years of eating experience.
    I recommend everyone to eat, it is a very essential thing in the human body.
    For number 2 -> Tingling in the throat is only at the beginning, over time you won't feel anything anymore.
    Like me, I eat it like a green cucumber. And I keep the smell to myself
    I wish I could make a perfume out of it because it's great.

  20. I did not understand anything! Hebrew please! Explain what exactly garlic is good for us and how it contributes to our body in simpler language, not all of us are scientists like you!

  21. I suffered from acute inflammation of the prostate with radiation towards the crown and I could not live a married life. I went to gastrologists and dermatologists and nothing helped me. I suffered terribly for a year plus until I discovered this thing called garlic, especially Chinese garlic. What can I tell you, it improved the quality of life beyond recognition. I am today. I eat garlic, sometimes Chinese, sometimes Israeli, morning, noon and evening with meals, so there is a smell, but I feel great. I take garlic ice cream, peel it in my mouth at the same time, chew it with the food. It is also good for cholesterol. It cleans all the internal systems of the body well. Very good for healthy people too

  22. Garlic is healthy to eat when you bite into it until it breaks down into tiny pieces in your mouth, so the active substance is better absorbed in the tissues of the oral cavity and in the body itself.

  23. I don't know why you find it so problematic to eat it.
    This is unusual from a health point of view. Although it does smell a little, especially when you sweat, but that's what a shower is for, and also parsley.

    Garlic is very healthy. It helps to clean the blood of toxins, it improves the functions of the heart, and it protects against all kinds of diseases and things that many modern medicines do not know how to treat at all.
    It is so full of health that it is considered the antibiotic from the plant.

    Although it smells a little, but if you swallow it, it really does not make your breath smell, and this is from my experience with my friend who did it when she was sick.

    Apart from that, the unusual physical health that it encourages covers up the whole thing especially as I said it's from there that if you sweat you feel it but for that there is a shower and a deodorant that neutralizes the body odor which in any case - is not exactly something that others should smell.

    It is a vegetable that is considered so beneficial for the human body that there is no dilemma at all - because if the decision is between showering once a day anyway and putting on deodorant or not to recover from an illness, flu or other health problem, then there is no doubt here.

    And it's not huge amounts at all - swallow one clove of garlic a day and that's it. And there is no discomfort, only a good smell and complete health - physical and mental.

  24. Garlic is so stinky
    People who eat garlic are just insanely stinky people, without limit

    How can you not smell the repulsive smell from afar and say that it tastes good or smells good,
    There is no limit to the disgust of people

    And that you swallow it, or eat parsley - will not remove the smell.
    The smell of the most microscopic piece of garlic stays in the blood for about a month
    And you feel it all day, in a certain dose, at least those who are sensitive to smells feel it on themselves - even a month or two later.

    Kills me how people can eat such huge amounts of garlic and live with it,
    After all, you probably no longer remember what a clean body odor is, without this repulsive feeling and discomfort in the body

  25. According to various definitions I have come across, I think the answer to the question of what the term health refers to is this from all kinds of sources on the net:
    Health is defined as a combination of what is called efficiency in function and efficiency in the metabolic processes in a living body. According to conventional wisdom, health consists of several factors for the definition of health and they are the environment, the biology of the organism, the way of life Lifstyle and the health management of that organism, and hence the link will be broken between the ability of the individual to influence his health and not only through passive means by healing.
    The health of the body often also refers to the functional integrity of cell assemblies - that is, at the cellular level as well as at the process physiological level. However, it should not be confused because health also refers to the macro level and refers to the ability of the individual as a complete system to respond and function in an efficient and balanced manner to the factors of vigilance that are perpendicular to his development.
    The definition of the World Health Organization, which defined health as a state in which comfort is experienced on the physical, social and psychological levels, the organization gives a broader definition to the term health as mentioned, and its definition does not refer only to the state in which we do not experience diseases, but to a wider field of effective functions as mentioned.

  26. A derivative question that comes to me from all the discussion here is regarding that health - a term that has become so commonplace and so trendy to refer to in any matter. Everyone refers to what mental health is, and what physical health is, but to me it is not quite clear what it means to be healthy. Does it mean metabolic health? Is it for the normality of cells and organs in the body? When we talk about health in the context of nutrition, do we refer to the effectiveness of the substances that are absorbed as affecting the improvement of the functions of the body's general systems, such as the liver, or do we refer to the fact that the substances that are absorbed into the bloodstream, for example, are healthy for us because they fight against disease causes.
    I am not knowledgeable in the field of biology and physiology, nor in what concerns the exchange of substances and issues that would surely clarify the subject for me, and perhaps someone does actually know what the exact meaning is when the term health is used, and whether it is in the context of proper nutrition and in the context of body health, a correct lifestyle , fitness, physical health and in general when using the same medical terms or whether they are no longer medical but have a simpler and broader meaning such as the health of the woman and the man, the health of the baby or to check the health of the back or the health of the bones because I need to be treated because I have osteoporosis or calcium leakage or or health as a result Taking garlic or any other beneficial vegetable. Thanks to those who understand

  27. Garlic has properties for health that are unusual for one such special vegetable that contains so much medical wealth... (some people are allergic to garlic and some it hurts their pancreas because of its spiciness)
    Experts talk about the effectiveness of garlic in lowering cholesterol for those who suffer from it, and lowering the blood sugar level and preventing gynecological problems such as period pains, period infections and more.

    A body of knowledge from many studies indicates that the components of garlic contribute to health because they allow the body to deal with infections and fungi through the active components, garlic destroys free radicals that cause cancer, and there are even studies that indicate that it heals cancer cells and fights them - nothing less and nothing more!
    Garlic also prevents calcification of the arteries, significantly lowers the chance of heart disease and helps the health of those who suffer from kidney and urinary tract disorders as a result of stones.

  28. With all the benefits of garlic, you really need to pay attention to the caveats and certainly to the dose that may also bring harm

  29. There is no problem which is its pungent smell.
    One of the solutions is really to swallow garlic capsules which, according to what I understand, greatly improve the body's resistance, the efficiency of the metabolism and it has medical properties for financially sound health since it is considered a natural antibiotic. In any case, the damage is possible in the form of excessive acidity. Even those who do not want to risk their health because they do not trust all these capsules that are considered effective because of the high concentration of the active substance in them - a concentration of substances that may actually cause health damage if taken in too large an amount, can swallow a tooth or two teeth a day immediately after eating or even together with food and a little food after swallowing in a way that neutralizes the pungent smell of garlic.

    What was not mentioned is that it should be noted that garlic can be harmful to health if you eat it on an empty stomach, then it is very acidic and spicy and can damage the walls of the intestine. This is very unhealthy - and whether someone is sensitive to acidity in the digestive system or not, you should pay attention to this.
    All the medicines for healing the body of all those who are passionate about being strong with the help of natural medicines, can cause damage and actually harm health!

  30. I agree with the advice given. It has an excellent effect on the body and is a component with a great medical effect. As far as I know, in order to achieve good health, it is advisable to take two teeth that are not too big - this can make you very healthy and it leads to a dramatic improvement in the immune system. It is known that the virtues of garlic are a recipe for longevity and a lot of physical health (as far as I know it has no effect on mental health and mood). In terms of metabolic efficiency, garlic improves the state of health probably because it is a first class antioxidant which improves the efficiency of the immune system and contributes to health by attaching to free radicals which are significant causes of morbidity in autoimmune diseases such as cancer.
    However, I would recommend not to get carried away in swallowing garlic and not to exceed more than two cloves of garlic a day, preferably after the meal. Garlic is also considered fatal for intestinal diseases caused by parasitic bacteria. However, it is of course advisable to go for a comprehensive examination for the general health examination before taking it as a treatment for such things.
    Furthermore, it should be noted that garlic is indeed considered very healthy when taken in a limited and controlled dose. It is possible, by the way, to avoid the odors caused by garlic in the mouth by taking capsules that are bought quite cheaply in all kinds of pharmacies, but you have to note that they are concentrated.

    good luck to you

  31. As I said, I prefer my garlic packaged in its natural form, as a garlic clove, and not as a tablet that I have no idea what happened to it until it reached its current form and how the processes it went through affected its chemical and nutritional composition (I also mean the crushing and drying process)

    Anyway, thanks Erez 🙂

  32. I'm not exaggerating anything here (literally), but there is no connection between the word "synthetic" and natural garlic tablets. It is specifically the same garlic, grown in the ground, crushed and packaged. It does not undergo any chemical modification, except for crushing and packaging as a tablet. This is not some compound concocted in a lab.
    But of course I respect people who prefer to see their food in its natural form as well (that's why they buy a cow, not an eye steak). But then you also have to accept the accompanying meanings (loud noises at five in the morning in the case of the cow, and babble in the case of the garlic).
    Shabbat Shalom to all.

  33. Friend, thank you very much for the answers. And regarding the tablets, basically I am against these things, I prefer to eat the real thing and not synthetic imitations.

  34. Yo!
    I was really writing how much I love garlic and suddenly I had such a loud ringing in my right ear! Something really strong and unrelated!

    Does anyone know why this is happening?

  35. Yogev's advice is known to be useful, but it is advisable not to accidentally confuse it completely with cilantro,,:) because then we are in another bad trouble,,

  36. Hugin:
    The truth is, I really like the smell too.
    It is generally known that most of the subjective sense of taste is actually an interpretation of smell.
    The combination of the taste of garlic (cooked or not - depends on the nature of the food) and its smell can turn almost any food into a delicacy for me.

    Yogev:
    Since I also really like parsley (especially the parsley salad that one of my sisters-in-law makes with olive oil, almonds and Bulgarian cheese plus some spices) I definitely intend to implement your advice.

  37. Regev, about the smell..
    If I'm not mistaken, if you eat parsley after the garlic, the smell should go away.
    try out..

  38. :)Michael: So maybe you're really al-Housi?:) Taste filled but the smell?

    Besides: the research is very shallow relative to the many qualities attributed to him, his fans.

  39. Society:
    Garlic is one of the tastiest things on earth.
    I eat garlic for fun and in order not to get into embarrassing situations because of the smell, I limit my contact with others immediately after eating the garlic.... for talkbacks.
    Does anyone here smell that just a moment ago I drank a glass of satiety that I dipped in salt, pepper and crushed garlic in quantities?

  40. Answer to Elad, from comment 2:
    Allicin - which is the active ingredient in garlic, and to which the "good" properties are attributed - is completely broken down during cooking, so for many years there is complete agreement in science that garlic is only healthy when it is fresh (not cooked).
    At the same time, there is a solution to the issue you raise "Is it possible... to still enjoy its health benefits?": many manufacturers of food supplements (what are more commonly called natural medicines or vitamins) market "garlic capsules". Swallow these capsules like you swallow a pill, they do not cause a bad taste or smell in the oral cavity, and they contain garlic extract. This way you can enjoy the benefits of fresh garlic, without chewing fresh garlic.
    If possible, I would advise you not to buy a large quantity of caps from one manufacturer, but to try several different manufacturers. Although the contents of the capsules are almost the same, there are differences in the type of envelope (what is called drug delivery). Such differences can be very significant to different users. For example: a shell that breaks down quickly, compared to a slower release in the stomach cavity. Gelatinous shell versus the hardening of the pressed garlic perimeter. Some capsules may cause garlic "gurgling" in different users, while other capsules will be digested without interruption. That is why it is recommended to try several manufacturers, and after you have found a favorite manufacturer - continue to purchase only from him.

    general comment:
    The researchers cited in this article referred to only one property of allicin (as an antioxidant), but many other properties are known that make it such a healthy ingredient, the most prominent of which should be noted being antibacterial (kills bacteria) as well as antifungal (kills fungi), useful against Arteriosclerosis, lowers blood pressure and more.

  41. Garlic is spicy and therefore burns when you eat it. As far as I understand, garlic loses a lot from cooking, etc

    Me and some of my friends, relatives and other people I know or who eat it for good health and it really helps with colds as well. They use it for this purpose as follows: chop it small and after eating something like bread, before swallowing the chewed food, put some of the chopped garlic in your mouth and swallow together like a ball Not noticeable, no smell and no taste.

    Or others of my acquaintances simply take a clove of garlic a day cut into 4 pieces like a small ball and swallow it with water without a problem.

    Instead of eating it and it is smelly and spicy for some people, it is a good solution without aftertaste and flavors and achieves the same effect

  42. Can anyone tell me if garlic loses its health properties while cooking in water? Because when you eat it as it is without cooking, it causes a strong and very unpleasant feeling of burning and stinging in the throat, especially if you drink afterwards a carbonated drink like black beer or cola... The question is if it is possible to cook it in water (which increases the burning sensations) and still enjoy its health benefits?

    Thank you very much to the respondents.
    Thanks.
