Overall, according to the 22 studies analysed, garlic was found to be effective at lowering total cholesterol and low-density lipoprotein.
Low-density lipoprotein is one of two types of cholesterol, the other is known as high-density lipoprotein.
Where they differ is in their impact on the body.
Whereas high-density lipoprotein is essential for overall health, low-density lipoprotein builds up as a plaque in the arteries, causing high blood pressure.
