Garlic contains antioxidants that may help prevent dementia and Alzheimer's disease

Garlic comes from the Mediterranean coast and western Asia. It's been used as a spice and natural medicine for centuries. Garlic is known to have natural antioxidants that help lower lipid peroxides and LDL oxidation by removing reactive oxygen species (ROS).

Free radical oxidative damage adds to the aging process. Garlic is high in antioxidants, which help the body's natural defenses against oxidative. Garlic supplements at high doses have been found to boost antioxidant enzymes in humans and lower oxidative stress in persons with high blood pressure. The antioxidant properties and combined effects on lowering cholesterol and blood pressure may reduce the risk of common brain diseases including Alzheimer's disease and dementia.
