1, promote blood circulation

Olive oil can prevent atherosclerosis and the complications of atherosclerosis, hypertension, heart disease, heart failure, kidney failure, cerebral hemorrhage.

In the book by Dr. Artemis Simopoulos, "Omega Health. A Simple and Easy Plan for Longevity" by Dr. Artemis Simopoulos, it is mentioned that the omega-6 fatty acids in cooking oil constrict the arteries, thus forcing the heart to work overtime and causing high blood pressure. In contrast, the omega-3 fatty acids in olive oil increase the amount of nitrogen oxide, an important chemical that relaxes your arteries, thus preventing arterial damage caused by high blood pressure.

Also omega-3 fatty acids prevent the formation of blood clots in two ways. First, it reduces the viscosity of platelets, making them less likely to become entangled with fibrinogen, and second, omega-3 fatty acids reduce the amount of fibrinogen, which also greatly reduces the chances of blood clots forming.

2, improve the function of the digestive system

Olive oil contains more than any vegetable oils are high in unsaturated fatty acids, rich in vitamins A, D, E, F, K and carotene and other fat-soluble vitamins and antioxidants and a variety of other components, and does not contain cholesterol, and therefore the human body digestive absorption rate is very high. It has the function of reducing gastric acid, preventing the occurrence of gastritis and duodenal ulcer;

And can stimulate the secretion of bile, stimulate the vitality of pancreatic enzymes, so that the degradation of fats and oils, is absorbed by the intestinal mucosa, in order to reduce the occurrence of cholecystitis and gallstones. There is also laxative function, long-term consumption can effectively relieve constipation.

3, protect the skin

Olive oil is rich in squalene and essential fatty acids with excellent skin affinity, rapid absorption, and effectively maintain skin elasticity and moisturizing;

Olive oil is rich in monounsaturated fatty acids and vitamins E, K, A, D, etc. and phenolic antioxidant substances, can eliminate facial wrinkles, to prevent the skin from aging, skin and hair and prevention of chapped hands and feet. Hands and feet chapped and other effects, can be "eaten" beauty care products, in addition to olive oil coated skin can fight ultraviolet rays to prevent skin cancer.

4, improve the function of the endocrine system

Olive oil can improve the metabolic function of the organism. This is because olive oil contains more than 80% of monounsaturated fatty acids and omega-3 fatty acids, and omega-3 fatty acids in the DHA can increase insulin sensitivity, when the higher the content of unsaturated fatty acids in the cell membrane, the higher the number of double bonds, the more active it is. DHA, with its six double bonds, is the most unsaturated fatty acid and therefore makes the cell membrane the most active.

The more active the cell membrane, the greater the number of insulin receptors and the more sensitive it is to insulin. When the body consumes the right proportion of fatty acids, the metabolism is more normal, and the chances of obesity and diabetes are reduced. The latest research results show that the glucose content in the body of healthy people can be reduced by 12% after consuming olive oil. So now olive oil has become the best cooking oil to prevent and control diabetes.

5, the benefits of the skeletal system

Olive oil in the natural antioxidants and omega-3 fatty acids help the body to absorb minerals such as calcium, phosphorus, zinc, etc., can promote bone growth, in addition to omega-3 fatty acids to help maintain bone density, reduce free radicals (highly reactive molecules) caused by osteoporosis of the bones.
