Known by many health conscious consumers concerned about cholesterol to be a great protein substitute, egg whites may also help lower blood pressure. The new study was presented at the 245th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society, which stated that egg whites could be an effective adjunct, either as is or as supplements, to high blood pressure medication. Instead of depending just on medication to lower blood pressure, egg whites are now presenting the possibility of working with medication and other natural treatments to further help manage blood pressure.
According to Science Daily, Zhipeng Yu, Ph.D. and colleagues of JilinUniversity in China – who are also researchers with ClemsonUniversity – stated that, “Our research suggests that there may be another reason to call it “‘the incredible, edible egg’”. We have evidence from the laboratory that a substance in egg white — a peptide, one of the building blocks of protein — reduces blood pressure about as much as a low dose of Captopril, a high-blood-pressure drug.” The study revealed that the peptide RVPSL – used in the research – has a powerful ability to block or inhibit the action of angiotensin-converting-enzyme (ACE), a substance produced in the body that raises blood pressure.
To get the most out of your eggs, the researches further indicated that there are other studies showing, as in the ACS’ Journal of Agricultural and Food Chemistry that fried egg proteins cooked at high temperatures showed a greater ability to lower blood pressure than eggs boiled at 212 degrees F.
Note that, the research was conducted on laboratory rats that developed high blood pressure and were acting as stand-ins for humans in such early research on hypertension. It is not yet confirmed whether the findings have been peer-reviewed by other scientists, which is, according to Target Health, “a common practice designed to ensure studies are conducted correctly.” Only with further testing and of humans, can researches confirm for sure whether egg whites can act as an adjunct to high blood pressure medicine.
Until we are 100% sure, we advise our blood pressure community to consult with their health care provider before making any changes, especially in response to this new research. That said, egg whites are a healthy protein that you can safely add to your daily menu, just go easy on the frying. Plus, it’s a meal that you can easily order at most restaurants, diners and cafes and that is easy to control the salt intake. While you can not yet turn to white eggs to lower blood pressure, it is a healthy protein.
