Heart Disease: Just as there are many factors that cause heart disease, there are many benefits of garlic that aid in preventing and treating it. So how can garlic help keep our heart in check? First, it helps lower our cholesterol levels. It raises our HDL (good) cholesterol levels, prevents LDL (bad) cholesterol from building up on arterial walls. This reduces the chances of plaque forming in our arteries. It has also been shown to lower cholesterol levels by 9% in people who ate 2 cloves of garlic per day.
Recent studies have also shown it to protect the aorta. The aorta is the heart blood vessel that maintains blood pressure and flow while the heart is pumping. Age, poor diet and environmental factors such as smoking can damage the aorta, causing it to stiffen. Studies have also shown that regular consumption of garlic slows the aging of the aorta and helps keep it flexible.
