It might surprise you that sesame oil has some interesting heart-health and cancer-prevention benefits. When used in combination with sunflower oil, sesame oil helps lower blood pressure in patients with hypertension. A 4-year study conducted at Rajah Muthiah Medical College and Hospital and Annamalai University in India, published in the April 2011 “Saudi Medical Journal,” concluded that the oil mix lowered both blood pressure and LDL cholesterol levels in the subjects treated. Sesamin, an antioxidant phytochemical in sesame oil, caused cancer cells to consume themselves in a study at Sapporo Medical University School of Medicine. The study, published in the “International Journal of Oncology” in July 2011, showed that sesamin activated tumor suppressors in colorectal cancer cells.
