Garlic: Benefits, Contraindications, and Consumption Tips from a Nutritionist

What are the benefits of garlic and who should avoid it

Garlic is not just a fragrant seasoning for dishes, but a true treasure trove of biologically active substances. The main value of garlic is allicin, a volatile sulfur compound that forms when the cloves are cut or crushed, responsible for both the sharp smell and the main healing properties of the product[2][3][4].

Main health benefits of garlic

• Antibacterial and antiviral action: garlic is essential for the prevention of ARVI and combating viruses and bacteria[1][2][3].
• Lowering blood pressure: sulfur compounds help to gently reduce elevated blood pressure[1].
• Normalization of cholesterol: regular consumption contributes to improving the lipid profile of the blood[1].
• Blood thinning and prevention of thrombosis: garlic reduces the risk of blood clots[1].
• Prevention of premature aging and age-related diseases
• Support for immunity and liver function[1].

When garlic can be harmful

Like any potent remedy, garlic has its contraindications:

• During exacerbation of gastrointestinal diseases (gastritis, ulcers, pancreatitis, etc.)[1].
• In serious liver diseases[1].
• When taking anticoagulants (blood-thinning medications)[1].
• In hypotension (low blood pressure)[1].
• In epilepsy[1].
• In case of allergies or individual intolerance[1].
• During pregnancy and breastfeeding[1].

How to properly eat garlic

For maximum benefit, nutritionist Yulia Popova recommends:

1. Before consumption, leave fresh garlic crushed at room temperature for 5–10 minutes — this will increase the amount of allicin[1].
2. It is better to eat garlic raw, starting with half or a whole clove per day[1].
3. To maintain health, 1–2 cloves daily is sufficient[1].

Garlic is a valuable product for the prevention of many diseases; however, as the expert emphasizes, it is important to consider individual characteristics of the body and the presence of contraindications[1][2][4].
