2. Garlic

Garlic is also considered one of the better foods that support your arteries. Studies have found that garlic can help prevent heart disease, lower blood pressure, and slow down atherosclerosis. In a study published in the journal Atherosclerosis in 1999, researchers found that garlic could prevent plaque buildup in the arteries.[10]
A review published in the journal Nutrition in 1997 found that clinical trials on garlic had positive effects in the prevention and treatment of atherosclerosis.[11] Another study from 1999 also found that garlic can reduce the risk of stroke and heart attack by more than 50%.[12] Garlic is thought to help against strokes and heart attacks since garlic acts as a blood thinner.
