Discover all about grape seed oil and its medicinal properties . Little is known about this natural product but it has great health benefits .
Researchers say that grape seed oil has many health benefits. This includes reducing the levels of cholesterol in the blood and reducing the risk of heart disease.
What is grape seed oil and how is it made?
Grapeseed oil is processed from grape seed, which is a by-product of wine production.
From the commercial point of view, the production of this oil is a brilliant idea. For thousands of years, wine producers have been left with tons of this by-product useless.
Thanks to technological progress, producers can now extract oil from the seeds and make a profit.
In general, oils are extracted in factories by grinding seeds and using solvents. However, the healthiest types of vegetable and plant oils are cold pressed.
Some fear that traces of toxic solvents such as hexane may adversely affect human health.
However, virtually all solvents are removed from vegetable oils during the production process.
It is currently unknown whether traces of hexane in vegetable oils cause harm to humans over time, but the adverse environmental effects of hexane are more concerning. Recently, the research focuses on developing alternatives that are more respectful of the environment.
If your oil is not simple, how it is processed, you should assume that it has been extracted with chemicals such as hexane.
It has a low nutrient content, but contains many Omega-6 fatty acids.
The health claims of grape seed oil are based on supposedly high amounts of nutrients, antioxidants and polyunsaturated fats.
Fatty acid composition of grape seed oil
It is very rich in polyunsaturated fatty acids, mainly omega-6. Researchers have speculated that high consumption of omega-6 fats in relation to omega-3s can increase inflammation in the body.
This theory is supported by several observational studies, which were associated with a high intake of foods containing omega-6 fatty acids with an increased risk of chronic disease.
However, controlled studies show that linoleic acid, a type of omega-6 fatty acid in grapeseed oil, does not increase blood levels of inflammatory markers.
If the high consumption of omega-6 fatty acids promotes the disease is currently unknown. High-quality studies are needed to investigate the effects of omega-6 fatty acids on hard end points, such as heart disease.
Grape seed oil also contains significant amounts of vitamin E. One spoon provides 3.9 mg of vitamin E, which is 19% of the daily intake.
There are practically no other vitamins or minerals in grape seed oil.
Grape seed oil: medicinal properties
Few studies have investigated the effect of grape seed oil on human health.
A two-month study involving overweight women 44. Compared the health effects of daily use of grape oil or sunflower oil.
Compared to sunflower oil, grape seed oil improved insulin resistance and decreased the level of C-reactive protein (CRP), a common marker of inflammation.
It also seems to have an antiplatelet effect, which means that it reduces the tendency of the blood to coagulate.
However, some grape seed oils may contain potentially harmful levels of polycyclic aromatic hydrocarbons (PAHs) that are known to cause cancer in animals.
It is not known how common this problem is or if it is a real cause for concern. Other vegetable oils, such as sunflower oil, may also be contaminated with PAH.
Although there are certain indications that high quality grape seed oil may have certain advantages, serious reservations can not be made at this time.
Is it good cooking oil?
Grapeseed oil has a moderately high combustion point. For this reason, it is recommended as a good option for frying. But beware! Not everything that is commercially advised is healthy. Grapeseed oil is also rich in polyunsaturated fatty acids. These fats tend to react with oxygen at high temperatures, creating harmful compounds and free radicals.
Because grapeseed oil is incredibly rich in polyunsaturated fatty acids, it is one of the worst oils that can be used for frying. However, it can be used in dressings for salads or baked goods, without problems.
The best oils, which contain mostly saturated fats or monounsaturated fatty acids, are olive oil, since it is less susceptible to reaction with oxygen when heated.
For this reason, you should avoid frying in grape seed oil. Instead, you can use it as salad dressing or mayonnaise ingredient.
Grape Seed Oil Summary Grape seed
oil is processed from grape seed, which is a rich by-product of wine production.
It is relatively rich in vitamin E and phenolic antioxidants, as well as a rich source of omega-6 fatty acids. Unfortunately, there is no research on grape seed oil. Therefore, its effects on health have not yet been fully determined.
