Patients with hypertension are best served with vegetable oils such as peanut oil, sesame oil and olive oil. Peanut oil is rich in niacin and sulfite, which can reduce fat and cholesterol in the blood, soften blood vessels and promote blood flow. Sesame oil contains a large amount of linoleic acid and vitamin E. Linoleic acid is synthesized with other substances in the body as prostaglandins, which have anti-thrombotic, anti-coagulant and vasodilator effects. Vitamin E can promote calcium absorption, and adequate calcium intake can make blood pressure smooth and lower. The monounsaturated fatty acids in olive oil can reduce the content of cholesterol in the blood, and there is also a polyphenolic substance that can reduce the viscosity of the blood, promote faster blood flow, prevent the gathering of excessive harmful substances in the blood and thus regulate blood pressure, so the consumption of vegetable oil by hypertensive patients is also a healthy diet.
