Sesame oil helps reduce dose of blood pressure-lowering medicine

29.04.2003


Cooking with sesame oil in place of other edible oils appears to help reduce high blood pressure and lower the amount of medication needed to control hypertension, researchers reported today at the XVth Scientific Meeting of the Inter-American Society of Hypertension. The meeting is co-sponsored by the American Heart Association’s Council for High Blood Pressure Research.



Using sesame oil as the sole cooking oil for 60 days along with drug treatment lowered patients’ blood pressure levels from 166 millimeters of mercury (mm Hg) systolic pressure (the top number in a blood pressure reading) to 134 mm Hg, and from 101 mm Hg diastolic (the lower number) to 84.6 mm Hg.

The researchers also report that the dose of nifedipine, a calcium channel blocker, was reduced from 22.7 mg per day to 7.45 mg per day by the end of the study.


"The affect of the oil on blood pressure may be due to polyunsaturated fatty acids (PUFA), and the compound sesamin – a lignan present in sesame oil. Both compounds have been shown to reduce blood pressure in hypertensive rats. Sesame lignans also inhibit the synthesis and absorption of cholesterol in these rats," says primary author Devarajan Sankar, D.O., Ph.D., a research scholar at Annamalai University, Chidambaram, Tamil Nadu, India.

Sesame oil contains 43 percent polyunsaturated fatty acids and 40 milligrams (mg) of vitamin E per 100 grams, according to the researcher. The research team has previously reported that sesame oil helps reduce blood pressure in hypertensive patients taking diuretics or beta blockers, and that sesame oil helped people with diabetes regardless of high blood pressure. Their current study tested the effect of sesame oil on people with hypertension who were already taking the calcium channel blocker drug nifedipine. Calcium channel blockers lower blood pressure by relaxing the arterial membranes.

Researchers identified 328 patients (195 men, 133 women, average age 58) who were taking 10-30 mg of nifedipine a day. They had moderate to severe long-term hypertension but no history of heart disease or stroke. Their average blood pressure was 166/101 mm Hg, which is considered stage 2 hypertension. Participants consumed an average of 35 grams of oil per day for 60 days. Researchers measured blood pressure at baseline, every 15 days and on day 60.

"Overall, we’ve added to the growing body of knowledge that suggests regular consumption of sesame oil as the sole edible oil is beneficial in many ways, including blood pressure reduction," Sankar says. However, patients should always seek advice from their physician if they have questions about their high blood pressure treatment.

Co-authors are K.V. Pugalendi, Ph.D.; G. Sambandam, M.B.B.S.; and M. Ramakrishna Rao, M.D. The meeting is also sponsored by the Inter-American Society for Hypertension and the National Heart, Lung, and Blood Institute.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
