Oleic acid is the main omega-9 fatty acid found naturally in various animal fats and vegetable oils. It is colorless and odorless, although commercial samples may be chemically yellow; Oleic acid is classified as an omega-9 monounsaturated fatty acid, which is shortened with a fat number 18: 1 cis-9, it has the formula CH3 (CH2) 7CH = CH (CH2) 7COOH, and the name is derived from the Latin word oleum which means oil.
In nature, oleic acid is a common fatty acid, which is used as an ingredient in many foods in the form of triglycerides.

It lowers blood pressure
The oleic acid found in olive oil is beneficial for promoting cardiovascular health by lowering blood pressure. a
The study showed that the antihypertensive effect of olive oil was due to the high oleic acid.
Research shows that intake of oleic acid regulates the membrane lipid structure that controls G-protein signaling that is mediated by it and regulates blood pressure. The high content of oleic acid is responsible for lowering the effects of blood pressure.
Also, oleic acid is found in nuts, as nuts and oils contain a high percentage of it. It found that a diet rich in oleic acid shows equal effects in lowering cholesterol by maintaining HDL cholesterol levels and lowering triglycerides.

People with symptoms of prediabetes or type 2 diabetes should add more oleic acid to the diet.
Research has indicated that saturated fatty acid palmitic acid and monounsaturated fatty acid oleic acid have beneficial effects on insulin sensitivity and type 2 diabetes. It comes due to anti-inflammatory actions, and blocks the activity of the insulin signaling pathway.

Research shows an inverse relationship between monounsaturated fatty acid intake and cognitive decline. Healthy fats have been shown to prevent age-related cognitive decline and may work as a natural treatment for Alzheimer’s disease.
A study was conducted to evaluate fatty acid profiles in brain samples with mild cognitive impairment, Alzheimer’s disease and no cognitive impairment.
It was found that the postmortem brain plasma of people with Alzheimer’s disease and moderate cognitive impairment; They have lower levels of oleic acid, compared to those with adequate brain function.
Preventing ulcerative colitis
Those who suffer from ulcerative colitis should make oleic acid a part of the diet.
The study included 25,000 adult men and women living in the UK to assess the relationship between eating food containing oleic acid and the development of ulcerative colitis.
High intake of omega-6 fatty acids was associated with the development of ulcerative colitis, while high intake of oleic acid was inversely related to the development of ulcerative colitis.
Oleic acid and other free fatty acids boost the immune system and fight infections.
Laboratory and animal studies show that it has anti-bacterial properties and protective effects.
An animal study showed that consuming oleic acid has a beneficial role in sepsis, a life-threatening infection that spreads through the bloodstream.
The effect of oleic acid supplementation was examined on mice with sepsis which was found to improve clinical symptoms, prevent liver and kidney injury, increase survival rate and reduce unstable fatty acids in the plasma that enhance during the severe systemic inflammatory response.
