Top Health Benefits of Garlic
Garlic (Allium sativum) is best known for its active compound allicin, which gives it both its signature aroma and many of its health-boosting properties.
1. Supports Immune Function
Garlic enhances immune activity by increasing the efficiency of white blood cells. This helps your body fight infections like colds and flu more effectively.
2. Promotes Heart Health
Regular garlic intake may help reduce high blood pressure and lower LDL (bad) cholesterol, reducing the risk of heart disease.
3. Fights Oxidative Stress
Garlic is rich in antioxidants, which protect the body from free radical damage and chronic inflammation.
4. Regulates Blood Sugar
Some studies show garlic may help improve insulin sensitivity and lower fasting blood sugar levels, particularly in people with type 2 diabetes.
Possible Side Effects of Garlic
While garlic is safe for most people, it can cause problems in certain situations:
- Digestive issues such as bloating, gas, and acid reflux—especially when eaten raw
- Strong odor from the mouth and skin due to sulfur compounds
- Blood thinning, which can increase bleeding risk, especially during surgery
- Allergic reactions in rare cases, such as skin rashes or breathing problems
Who Should Be Cautious
Garlic is not suitable for everyone in large or supplemental amounts. Be careful if:
- You are pregnant or breastfeeding (culinary amounts are fine)
- You are taking blood thinners (e.g., warfarin, aspirin)
- You have gastrointestinal issues like IBS, since garlic is high in FODMAPs
- You plan to undergo surgery within 1–2 weeks
How to Use Garlic in Your Diet
Garlic’s versatility allows you to use it in many forms:
Raw Garlic
Minced raw garlic can be added to salads, dressings, or dips. It’s potent and delivers the most allicin.
Cooked Garlic
Roasting or sautéing garlic reduces its pungency and adds sweetness to your meals. Use it in stir-fries, soups, pastas, and sauces.
Garlic Supplements
Available as tablets, capsules, or aged garlic extract. Best used under medical supervision for long-term health goals.
Garlic-Infused Oil
Perfect for adding flavor to roasted vegetables, bread, or pasta. Be cautious of storage to prevent bacterial growth.
How to Store Garlic Properly
Storing garlic the right way helps preserve its flavor and medicinal properties.
Whole Bulbs
Keep in a dry, well-ventilated area at room temperature. Avoid refrigeration. Shelf life: 3 to 6 months.
Peeled Cloves
Refrigerate in an airtight container. Use within 7–10 days.
Chopped Garlic
Can be stored in oil for short periods (a few days in the fridge), but risk of botulism exists. Add vinegar or lemon juice to increase acidity.
Frozen Garlic
Chop and freeze in small portions for cooking use. This method preserves flavor but may alter texture.
Should You Eat Garlic Every Day?
Yes, if your body tolerates it well. Eating 1–2 cloves of garlic daily can help support your immune system, heart, and overall health. However, listen to your body and monitor for any side effects.
