What Walnut Oil Does


Benefits of Walnut Oil

In this article, we’ll be discussing the benefits of walnut oil. This oil, extracted through cold pressing techniques, is one of the most expensive oils around. But what makes this oil so special?

Walnut oil, one of the expensive natural oils on the market, is derived from walnuts, which are scientifically known as Juglans regia. Walnut oil has gained much popularity around the world and is cultivated in many countries including the United States. Both types of walnut oil contain monounsaturated and polyunsaturated fats, particularly linoleic, gamma-linolenic and oleic acids. These fats act as antioxidants and anti-inflammatory compounds. They are identified as healthy forms of fat, as a result of their quick energy conversion and other benefits.

It Reduces the Development of Atherosclerotic Plaques

Atherosclerotic plaque is caused by insulin function, bad cholesterol, high fat intake, and inflammatory processes, all in response to a vascular injury. Walnut oil, rich in cholesterol-free monounsaturated and polyunsaturated fats, lowers the levels of all these deposits.

It Manages Blood Sugar

This applies to people who are diabetic, and those who aren’t. Meals that contain fat decelerate the absorption of glucose into the bloodstream, thereby reducing insulin increase. What’s more? Walnut oil has stimulating actions on the pancreas to increase insulin synthesis in cases that the islet cells of the pancreas don’t produce insulin when due.

It Manages Psoriasis

Psoriasis is a severe auto-immune disease that causes accelerated skin turnover that appears as patchy scaly areas of skin. Walnut oil soothes the itching that comes with psoriasis. You may apply walnut oil at night and wash off in the morning for more effectiveness.

It Improves Brain Functions

Walnut oil enhances the flow of blood to the brain. It helps in memory retention and handling of cognitive skills even in old age.

Eliminating Insomnia

Walnut oil is a rich source of melatonin, a neurotransmitter chemical that is responsible for the regulation of the sleep-wake cycle in humans. Melatonin combats the effects of cortisol, a stress hormone, which prevents sleep.

It Prevents Hair Loss

Walnut oil contains some amounts of potassium. When applied topically to the scalp, this oil enhances the flow of blood to hair follicles.
A deficiency in nutrients and oxygen is the major cause of hair loss. Its hydrating property prevents scalp disorders that affect hair growth.

It Prevents Wrinkles

Walnut oil is rich in Vitamin E, a powerful antioxidant nutrient that nourishes the skin. It also keeps skin hydrated, and reduces cracking and risks of infections getting into the skin to cause structural degradation.

Promotes Bone Health

Walnut oil is a source of vitamin K, one vitamin that ensures proper bone mineralization. Bone mineralization is the deposition of essential minerals into the bone matrix for assured strength and longevity. This results in the prevention of fractures, breaks, and osteoporosis.

It Improves Male Fertility

Walnut oil enables stronger erection and is reliable for sperm count boost, improving their motility, and even overall shape. Abnormally shaped sperm have a lower possibility of penetrating and fusing with the female egg. They also have lower chances of survival as they trip down the cervix.

May Reduce Cancer Risk

Walnut oil has a way of working on genes that may increase one’s risk of developing cancer, to an extent which one level of cancer risk drops.

Fewer Migraine Attacks


Walnut oil has got some magnesium. This mineral prevents and treats migraine attacks. People who consume adequate levels of magnesium experience fewer migraine attacks than those who don’t. And for those who do, it’s not as severe. Magnesium is also beneficial for bone regulation and blood vessel health.
