Everyone is quite familiar with olive oil, as it's commonly used in daily life. Olive oil is a highly beneficial cooking oil we frequently consume, which is why its price is significantly higher than ordinary oils. This reflects its value, as olive oil's health benefits truly surpass those of other oils.Therefore, it's important to learn more about olive oil and keep it readily available at home. Avoid relying solely on a single type of oil. Let's explore some of olive oil's key benefits:
1. Promotes Blood Circulation
Olive oil helps prevent arteriosclerosis and its complications, hypertension, heart disease, heart failure, kidney failure, and cerebral hemorrhage. In Dr. Artemis Simopoulos' bookOmega Health: A Simple Plan for Longevity, Dr. Artemis Simopoulos notes that omega-6 fatty acids in cooking oils constrict arteries, forcing the heart to work harder and causing hypertension. Conversely, the omega-3 fatty acids in olive oil increase levels of nitric oxide—a vital chemical that relaxes your arteries—thereby preventing arterial damage caused by high blood pressure.Additionally, omega-3 fatty acids prevent blood clot formation in two ways. First, they reduce platelet stickiness, making it harder for platelets to bind with fibrinogen. Second, omega-3s lower fibrinogen levels, significantly decreasing the likelihood of thrombus formation.
2. Enhancing Digestive System Function
Olive oil contains higher levels of unsaturated fatty acids than any other vegetable oil, along with abundant fat-soluble vitamins (A, D, E, F, K) and carotenoids, antioxidants, and other components. Being cholesterol-free, it boasts exceptionally high digestibility and absorption rates in the human body.It helps reduce stomach acid, preventing conditions like gastritis and duodenal ulcers. It also stimulates bile secretion, enhances pancreatic enzyme activity, breaks down fats for absorption by the intestinal mucosa, and reduces the risk of cholecystitis and gallstones. Additionally, it has a laxative effect, and long-term consumption can effectively relieve constipation.
3. Skin Protection
Olive oil is rich in squalene and essential fatty acids that are highly compatible with skin, absorbing quickly to maintain elasticity and hydration.Its abundant monounsaturated fatty acids, vitamins E, K, A, D, and phenolic antioxidants help reduce facial wrinkles, prevent skin aging, and offer skin and hair care benefits—including preventing chapped hands and feet. It serves as an edible beauty product. Additionally, applying olive oil to the skin provides UV protection and helps prevent skin cancer.
4. Enhances Endocrine System Function
Olive oil boosts the body's metabolic functions.This is because olive oil contains over 80% monounsaturated fatty acids and omega-3 fatty acids. Among omega-3s, DHA increases insulin sensitivity. The higher the content of unsaturated fatty acids in cell membranes and the greater the number of double bonds they possess, the more active the membranes become. DHA, with its six double bonds, is the most unsaturated fatty acid, making cell membranes highly active.Highly active cell membranes contain more insulin receptors, making them more responsive to insulin. When the body consumes fatty acids in appropriate proportions, metabolism functions more normally, reducing the risk of obesity and diabetes. Recent studies indicate that healthy individuals who consume olive oil can lower their blood glucose levels by 12%. Consequently, olive oil is now recognized as the best cooking oil for preventing and managing diabetes.
5. Benefits for the Skeletal System
The natural antioxidants and omega-3 fatty acids in olive oil aid the body's absorption of minerals such as calcium, phosphorus, and zinc, promoting bone growth. Additionally, omega-3 fatty acids help maintain bone density and reduce bone loss caused by free radicals (highly reactive molecules).
6. Anti-Cancer Properties
Rich in monounsaturated and polyunsaturated fatty acids, olive oil's omega-3 fatty acids reduce the amount of linoleic acid tumors extract from the bloodstream, depriving them of a crucial nutrient.Omega-3 fatty acids also compete with omega-6 fatty acids for enzymes required in tumor metabolism, making cancer cell membranes more unsaturated and vulnerable to destruction. This inhibits tumor cell growth and reduces tumor incidence. Consequently, it helps prevent certain cancers (breast cancer, prostate cancer, colon cancer, uterine cancer):Additionally, omega-3 fatty acids (polyunsaturated fatty acids) enhance the efficacy of radiotherapy and chemotherapy. These treatments kill cells by unleashing free radicals (highly reactive molecules) that attack cell membranes. When cell membranes sustain sufficient damage, cancer cells undergo self-destruction. Omega-3 fatty acids make cell membranes more susceptible to free radical attacks, thereby boosting the effectiveness of chemotherapy and radiotherapy.
7. Radiation Protection
Due to its polyphenol and lipopolysaccharide content, olive oil also offers radiation protection. Consequently, it is frequently used in astronaut food formulations.Frequent computer users particularly value it as a health and skincare product. Before prolonged computer use, massage olive oil onto the face and eye corners, or achieve similar effects by using bath products rich in olive oil. Note that the radiation-protective efficacy varies depending on the olive oil's lauric acid content.
8. Infant Nutrition
Based on its composition and digestibility, olive oil is the most suitable oil for infants. Half of an infant's calories come from fats in breast milk. After weaning, these calories must be obtained from dietary fats.The ratio of alpha-linolenic acid to linoleic acid in olive oil—nutrients the human body cannot synthesize—mirrors that in breast milk. Highly absorbable, it promotes neural and skeletal development in infants and young children. It serves as an excellent nutritional supplement for pregnant women and a fetal growth enhancer, while also providing exceptional nourishment during postpartum and lactation periods.
9. Anti-Aging
Among olive oil's numerous components, carotene and chlorophyll impart its yellow-green hue. Chlorophyll stimulates metabolism, promotes cell growth, and accelerates wound healing. It also enhances appearance by reducing wrinkle formation.Studies indicate that olive oil's antioxidants neutralize free radicals in the body, restoring organ health, preventing brain aging, and promoting longevity.
10. Prevention of Cardiovascular Diseases
Olive oil protects the cardiovascular system in multiple ways: ① It prevents inflammation by lowering homocysteine (an amino acid that damages coronary artery walls), reducing arterial wall injury. ② It relaxes arteries and lowers blood pressure by increasing nitric oxide levels in the body.③ The monounsaturated fatty acids in olive oil reduce the oxidation of LDL cholesterol. ④ A substance called squalene in olive oil increases HDL (good cholesterol) levels while lowering LDL (bad cholesterol) levels. Higher HDL cholesterol levels in the body correspond to fewer oxidized LDL cholesterol particles in the arteries.Recent studies demonstrate that middle-aged men who consumed olive oil experienced an average 13% reduction in total cholesterol, with dangerous "bad" cholesterol dropping by a remarkable 21%.⑤ Olive oil can slow blood clot formation by increasing omega-3 fatty acid levels in the body.
