Garlic has been present in the cuisine of different cultures for centuries. In Brazil, it is practically indispensable in the preparation of rice, beans, meats, vegetables, sauces, and many other recipes.
In addition to its characteristic flavor and aroma, raw garlic contains natural compounds that are of scientific interest. Among them is allicin , formed mainly when a fresh garlic clove is cut, crushed, or minced.
This doesn’t mean that garlic is a “cure-all.” The most balanced way to view it is as a nutritious and aromatic food that can complement a healthy diet.
What happens when garlic is crushed?
Intact garlic contains substances that, upon contact after the clove is cut or crushed, participate in the formation of allicin.
For this reason, some people prefer to crush the garlic and wait a few minutes before using it .
Allicin and other sulfur compounds in garlic have been studied for their biological properties. However, results observed in the laboratory do not automatically mean that eating garlic can treat infections or diseases in the human body.
This distinction is especially important in light of social media posts that attribute to garlic the ability to “kill dozens of bacteria” or eliminate different types of infection. A suspected or confirmed infection requires proper evaluation and, when necessary, specific medical treatment.
Garlic and its antioxidant action.
Garlic provides various plant compounds with antioxidant activity.
Antioxidants help protect cells against oxidative stress. However, this benefit should be understood within the context of the overall diet.
A diet rich in vegetables, fruits, beans, seeds, and whole grains offers a much wider variety of nutrients and protective compounds than relying on just one ingredient.
Can garlic contribute to cardiovascular health?
This is one of the most researched aspects of garlic.
Some studies suggest that consuming garlic or certain standardized preparations may produce modest effects on cardiovascular factors , including blood pressure and cholesterol levels in certain individuals.
However, the results depend on the amount used, the type of preparation, the consumption time, and individual characteristics.
Therefore, those with hypertension or high cholesterol should not stop taking their medication and replace it with garlic, tea, or any other home remedy .
One simple advantage: more flavor with less salt.
There is also a very practical benefit that doesn’t require turning garlic into medicine.
Garlic, onion, herbs, lemon, and other spices help to make food more flavorful. For some people, using these seasonings makes it easier to reduce the amount of salt added to meals .
This small change can be particularly interesting within a diet focused on cardiovascular health.
Warm water with garlic and lemon: how to prepare it?
A traditional recipe found in various wellness routines combines fresh garlic, water, and lemon. It can be consumed as an occasional food beverage, but it’s not necessary to drink it to obtain the nutritional benefits of garlic .
Ingredients
- 2 small cloves of fresh garlic
- 1 glass of warm water
- Juice of ½ lemon, optional
- 1 teaspoon of honey, optional
Preparation method
Peel and crush the garlic cloves. Let them sit for approximately 10 minutes .
Place the garlic in warm water and mix. Add the lemon and, if you wish to soften the flavor, a small amount of honey.
Prepare only the amount that will be consumed at that moment.
Important: there’s no need to boil several cloves of garlic or consume large quantities. More garlic doesn’t necessarily mean more benefits and can increase digestive discomfort.
Is it better to take it on an empty stomach?
There’s no need to drink garlic with water on an empty stomach for it to be part of a healthy diet.
In fact, people with sensitive stomachs may tolerate it better with a meal , such as breakfast.
Another even simpler alternative is to use garlic normally in your cooking: seasoning vegetables, beans, soups, sauces, or other homemade dishes.
How much garlic should you consume?
There is no universal amount that works the same way for everyone.
For culinary use, small amounts incorporated into meals are usually sufficient. Consuming many raw cloves at once can cause irritation without providing any proven additional benefits.
The body also doesn’t need a supposed “cleansing” done by garlic. The liver, kidneys, intestines, and other systems already continuously participate in the processing and elimination of substances from the body.
Possible undesirable effects of raw garlic
Although it is a common food, raw garlic can be quite strong. In some people, it can cause:
- heartburn or reflux;
- Discomfort or burning in the stomach;
- Gas and abdominal distension;
- nausea;
- Gastrointestinal irritation;
- Strong odor in the breath.
Those who experience a worsening of symptoms after consuming raw garlic can opt for cooked garlic in their meals or simply avoid preparing it altogether.
Who needs to be more careful?
Special caution is advised for people using anticoagulants, antiplatelet drugs, or other medications that interfere with coagulation , as high amounts of garlic or concentrated supplements may promote bleeding.
It is also wise to speak with a healthcare professional before significantly increasing consumption if there is a history of gastritis, ulcers, significant reflux, coagulation disorders , or scheduled surgery.
Concentrated garlic supplements deserve even more attention, as they are not simply equivalent to the small amount used to season food.
Does garlic fight infections?
This issue deserves an important distinction.
Compounds found in garlic have demonstrated antimicrobial activity under certain experimental conditions . This is interesting for research, but it does not prove that eating garlic or drinking garlic water can eliminate an existing infection in the body.
Bacterial infections may require specific antibiotics, while viral, fungal, and other conditions have different approaches.
Persistent fever, difficulty breathing, intense pain, confusion, rapid worsening of general condition, or other worrying symptoms warrant medical evaluation , rather than relying solely on home remedies.
How can we make the most of garlic in our daily lives?
There’s no need to create a complicated routine. Garlic can be naturally incorporated into your diet in dishes like seasoned beans, sautéed vegetables, soups, homemade sauces, meats, fish, and herb pastes .
Combining different plant-based foods is more nutritionally interesting than concentrating large quantities of a single ingredient.
Conclusion: a valuable food, without miraculous promises.
Raw garlic can be part of a balanced diet and offers interesting plant compounds, including sulfur compounds studied for their potential antioxidant and cardiovascular properties.
But there is a big difference between recognizing these properties and claiming that garlic “cures infections,” “cleans arteries,” or replaces medication.
To take care of your health in the long term, the path remains broader: a varied diet, adequate physical activity, quality sleep, hydration, monitoring of risk factors, and health check-ups when necessary .
Garlic can easily take its place in this routine — not as a miracle cure, but as a traditional, flavorful, and interesting ingredient for a more varied diet.
