Daily intake of garlic may reduce cholesterol and triglyceride levels, says a researchers from Shandong University in China. Compared with placebo groups, garlic consumption is associated with a 5.4% reduction in cholesterol levels and a 6.5% reduction in triglyceride levels.
“Although the size of the effect is modest, garlic therapy should benefit patients with risk of cardiovascular diseases, as garlic may also reduce blood pressure, decrease plasma viscosity, etc.,” the researchers wrote in the Journal of the Science of Food and Agriculture.
Garlic has been suggested to exhibit several health benefits, including inhibiting enzymes involved in lipid synthesis, decreasing platelet aggregation, preventing lipid peroxidation and increasing antioxidant status.
Garlic comes in different forms, including garlic powder (doses ranging from 600 mg to 900 mg per day), garlic oil (8.2 mg to 15 mg per day), or aged garlic extract (1.8 mg to 7.2 mg per day).
The most pronounced cholesterol-lowering effects were observed for garlic powder, while garlic oil produced the best triglyceride-lowering effects.
