Garlic is a popular kitchen ingredient known for its excellent flavor and various health benefits. It is used in many dishes worldwide and is considered a natural remedy for several ailments.

However, as with any food, there are people who should avoid or limit their consumption of garlic.

People with digestive issues

Garlic contains fructans, a type of carbohydrate that is difficult to digest, especially in large quantities. For some people, consuming foods high in fructans can lead to digestive symptoms such as bloating, gas, and diarrhea.

People with irritable bowel syndrome (IBS) or other digestive conditions should limit their garlic intake and monitor their symptoms.

People with bleeding disorders

Garlic has natural blood-thinning properties, which can be beneficial for overall health but can also increase the risk of bleeding and interfere with blood clotting.

People with bleeding disorders or taking blood-thinning medications should avoid garlic or consult with their doctor before consuming it regularly.

People on certain medications

Garlic can interact with certain medications, including blood-thinning drugs, immune system suppressants, and medications used to lower cholesterol.

If you are taking any medication, it is best to consult with your doctor before adding garlic to your diet.

People with allergies

Garlic allergies are relatively uncommon but can be severe. Symptoms may include hives, itching, swelling, difficulty breathing, and anaphylaxis.

If you experience any of these symptoms after consuming garlic, discontinue use immediately and seek medical attention.

People with low blood pressure

Garlic is known to lower blood pressure, which is beneficial for people with hypertension.

Pregnant and breastfeeding women

Garlic is considered safe during pregnancy and breastfeeding in moderation, but consuming large quantities can cause digestive discomfort and potentially alter milk flavor.

It is best to consult with a doctor before consuming garlic regularly during pregnancy or while breastfeeding.

People with diabetes

Garlic consumption has been linked to lower blood sugar levels, which can be beneficial for people with diabetes. However, for individuals taking diabetes medication, garlic supplementation may increase the risk of hypoglycemia.

It is best to consult with a doctor before adding garlic to the diet.

People with a history of reflux

Garlic can exacerbate symptoms of acid reflux, GERD, and heartburn in some individuals. The sulfur compounds found in garlic can relax the esophageal sphincter, allowing stomach acid to flow back into the esophagus.

For individuals with a history of reflux or digestive discomfort, garlic should be consumed in moderation and with caution.

People with thyroid disorders

Garlic is known to interfere with thyroid function by reducing the production of thyroid hormones and increasing levels of thyroid-stimulating hormone (TSH).

For individuals with thyroid disorders, consuming garlic regularly may exacerbate symptoms and should be consumed in moderation or avoided altogether.

People with liver and kidney disease

Garlic is metabolized in the liver and excreted in the urine, making it potentially harmful for people with liver and kidney disease. Consuming high amounts of garlic can worsen symptoms and lead to further damage.

It is best to consult with your doctor before consuming garlic regularly if you have liver or kidney disease.
