The health properties of walnut and its oil were known to man as far back as in ancient times. In Persia walnut was compared with brain, and its oil – with intelligence. In ancient Greece walnut tree was a symbol of life, and oil made of walnuts, “The King’s Acorns”, was forbidden to be used by commoners under death penalty. The similar tradition was in ancient Babylon, where priests gave permission to eat walnut oil only to wealthy people.
Walnut oil is used not only in medicine. Thanks to its sophisticated and smooth taste, it is an essential component of Greek, French and Caucasian cuisine. Walnut oil contains about 75% of omega -3 and omega -6 polyunsaturated fatty acids. Therefore, these acids should be consumed in moderation. In addition, walnut oil is the biggest source of vitamin F. Vitamin F may be able to normalize blood pressure, thus reducing the risks of heart attacks. But the main function of vitamin F is cholesterol excretion.
One way nuts may help your heart health is by lowering the low-density lipoprotein (LDL, or “bad”) cholesterol levels. LDL plays a major role in the development of plaque that builds up on the blood vessels.
Unsaturated fats. It’s not entirely clear why, but it’s thought that the “good” fats in nuts — both monounsaturated and polyunsaturated fats — lower bad cholesterol levels.
Omega-3 fatty acids. Omega-3 are a healthy form of fatty acids that seem to help your heart by, among other things, preventing dangerous heart rhythms that can lead to heart attacks.
Fiber. All nuts contain fiber, which helps lower your cholesterol. Fiber makes you feel full, so you eat less. Fiber is also thought to play a role in preventing type 2 diabetes.
Vitamin E. Vitamin E may help stop the development of plaques in your arteries, which can narrow them. Plaque development in your arteries can lead to chest pain, coronary artery disease or a heart attack.
L-arginine. Nuts are also a source of l-arginine, which is a substance that may help improve the health of your artery walls by making them more flexible and less prone to blood clots that can block blood flow.
Walnut oil is a very useful dietary product that is easy to digest. It is considered to be an excellent source of energy and vitamins. Therefore, it is not surprising that walnut oil is included into various diets. Walnut oil is good for face and body skin, hair and nails.
In cooking walnut oil is often used as a seasoning; it can add an exquisite taste to your salads and cold sauces. And it is very hard to imagine French and Caucasian cuisine without walnut oil. Nut oil, if overheated, can become bitter.
