1. Curcumin (in Turmeric)

Turmeric is a popular spice used in Indian and Ayurvedic cooking, but its true benefit comes from one active ingredient. The primary polyphenol in turmeric called curcumin has long been known for its cardioprotective effects. Turmeric extract is thought to reduce LDL cholesterol and the buildup of plaque in the arteries.
In a 2011 study published in the journal Molecular Nutrition & Food Research, researchers found that turmeric could reduce cholesterol and suppress early atherosclerotic lesions better than the cholesterol-lowering drug lovastatin.[8] Also, a 2006 study on mice suggested that curcumin can help prevent artery damage associated with carotid artery blockage.
