Garlic may serve as a natural “medicine” for elevated blood sugar and cholesterol levels, according to modern scientific research cited by the health portal HealthLine.
Scientists report that many of the health benefits of this pungent vegetable are linked to sulfur-containing compounds that form when garlic is chopped, crushed, or chewed.
The Key Compounds Behind Garlic’s Benefits
One of the most well-known compounds is allicin, which is present in fresh garlic for a short time after it is cut or crushed. Other biologically active substances include diallyl disulfide and S-allyl cysteine.
“Sulfur compounds from garlic enter the body through the digestive tract and travel throughout the body, exerting strong biological effects,”
— scientific experts explained.
Effects on Cholesterol and Heart Health
Researchers note that garlic may act as a natural cholesterol-lowering agent. Studies have shown that garlic supplements can reduce total cholesterol or “bad” LDL cholesterol by approximately 10–15%.
The beneficial effects on blood composition may also improve blood pressure levels and overall cardiovascular health.
Garlic and Blood Pressure
“High doses of garlic improve blood pressure in people with hypertension. In some cases, garlic supplements can be as effective as standard medications,”
experts reported.
Scientists emphasize that while garlic shows strong potential as a supportive natural remedy, it should not replace prescribed medications without consulting a healthcare professional.
