What are the positive health effects of cold pressed grape seed oil?
Grape seed oil is dominated by linoleic acid, which is an omega-6 fatty acid. These are essential fatty acids that the body cannot produce on its own and we need to consume with food. They play an important role in growth and development, as well as in brain functions. Due to the high content of linoleic acid, cold-pressed grape seed oil is good for the vital cardiovascular system . Oils high in unsaturated fatty acids, including linoleic and oleic acid, raise good cholesterol (HDL) and lower bad cholesterol (LDL) .Cold pressed grape seed oil is rich in phytosterols, which are the best known sterols in plant tissues. They are found in cereals, fruits, vegetables and vegetable fats. Because they are structurally similar to cholesterol, they can compete with them and displace cholesterol upon absorption in the gastrointestinal tract, which can lead to a reduction in blood plasma cholesterol. Phytosterols are thus linked to cardiovascular disease prevention (Modic and Kreft, 2001).
The next important elements in grape seed oil are tocopherols and tocotrienols, which are a form of vitamin E. The content of vitamin E in grape seed oil is high and ranges from 60 - 120 mg / 100 g. In other words, a teaspoon of cold-pressed grape seed oil contains 9 mg of vitamin E . Due to such a high content of vitamin E, grape seed oil is also one of the most stable oils (Lugue-Rodriguez et al., 2005).
In addition to vitamin E, cold-pressed grape seed oil also contains vitamins A and C. These elements act as antioxidants , which means that they bind free radicals in the body and thus inhibit oxidative processes. If there are too many free radicals in our body, they cause many unwanted chemical reactions due to their reactivity and thus damage the cells. Eating foods rich in antioxidants is supposed to inhibit the aging of the body and the emergence of diseases such as cancer, heart attack, diabetes and arthritis .
