Vegetable oil is a triglyceride that is extracted from a plant. This means that a plant's oil is only in liquid form when it reaches room temperature, and vegetable oil that is in substantial form when at room temperature is referred to vegetable fat. Many parts of a plant can yield oil, but when we are talking about using the oil for commercial purposes, the oil that is extracted is mainly from the seeds of the plant. Many vegetable oils found on the shelves of common food markets are not from a particular plant, but a mixture of various types of plants.
There are a couple of standard classifications of vegetable oils:
Source: Some vegetable oils that are extracted from the seeds or a different fruit can be classified by the source, such as it being "nut" oil.
Use: Many times, vegetable oils are used for cooking, but other categories could be that they are used for cosmetics, fuel, or medical purposes.
Below are seven beneficial health secrets of vegetable oils:
1. Improvement of Metabolism
Vegetable oil, specifically a high-quality olive oil, is said to increase the metabolism in individuals who are extremely overweight. A group of researchers, from the São Paulo State University in Brazil, published the results of this study in the Nutrition Journal a few years ago. The study concluded that olive oil contains anti-inflammatory, antioxidant and anti-blood clotting properties that aid in increasing the metabolic rate within the body.
2. Raising good cholesterol
Vegetable oil is said to have the capabilities to increase good cholesterol (HDL), which is necessary to keep blood vessels clean and to function properly. Also, vegetable oil will simultaneousl, also reduce bad cholesterol (LDL).
Healthy fats such as polyunsaturated fats and Monounsaturated fats usually lower the risk of diseases as well as decreases the levels of cholesterol. These healthy fats especially polyunsaturated fats are found in a variety of vegetable oils sunflower, olive, soy, canola, and corn oil.
3. Prevent atherosclerosis
Also, regular use of vegetable oil can prevent atherosclerosis, which is a disease that can turn deadly. It starts with plaque forming in the arteries, which will be a combination of cholesterol, fat, calcium, and other substances that are found in the blood. This plaque will harden over time, and the arteries will narrow, causing a restriction in the flow of much needed oxygen-rich blood getting to vital organs.
4. Decrease in Risk for Heart Disease
The State University, located in Buffalo, New York, conducted a study that points to vegetable oils reducing the risk of heart diseases. This study was published in the Journal of the American Medical Association. It was also shown through this study that blood glucose levels and blood pressure leveled out and returned to normal when vegetable oil was a major player in a daily diet.
5. Decrease in Risk for Breast Cancer
The Universita di Milano in Italy conducted a clinical study, and the results were printed in the publication Cancer, Causes, and Control. The study suggested that individuals who use vegetable oil (mainly olive oil) on a regular basis may be reducing their risk of developing breast cancer when compared to people who used butter.
6. Omega-3 Fatty Acids
Flaxseed oil, canola oil and nut oil are some vegetable oils that contain a healthy amount of omega-3 fatty acids. This is noteworthy because this important fatty acid is unable to be produced naturally in the body. The University of Maryland (Medical Center Division) states that omega-3 helps to keep the heart and brain healthy. Also, the body requires omega-3 fatty acids for normal development and growth. The American Heart Association suggests taking omega-3 fatty acids in the form of a vegetable oil, to prevent potential cardiovascular diseases.
7. Health Remedies
For a long period, olive oil's quality has been estimated according to its ability to produce tingling or burning sensation i.e., the more you cough, the better the oil. This inspired scientists to explain why this theory works and how it can be used to improve health. The Journal of Neuroscience published a paper that confirms olive oil's health-enhancing attributes. The study was conducted by Gary Beauchamp and the team of researchers of the Monell Chemical Sensors Center from Philadelphia. Researchers discovered that crushed Ibuprofen produced the same sensation which means that findings of this study could revolutionize the development of anti-inflammatory drugs.
A Complementary Therapies in Clinical Practice study discovered that castor oil packs can be used to control symptoms of constipation such as reducing the need to strain and the feeling of complete evacuation after the bowel movement. When applied onto skin, castor oil improves blood circulation and promotes healing. On the other hand, when taken orally it is broken down in the small intestine and stimulates the movements of the intestines.
Olive oil isn't only beneficial for overall health and wellbeing; it also plays a significant role in combating signs of aging and reducing fine lines and wrinkles. A study published in PLOS One discovered that consumption of monounsaturated fatty acids is associated with lower risk of severe photoaging in both sexes.
