WALNUT


Description

Walnut (scientific name juglans) is a tree, which belongs to the family of nutty.

The tree is known from antiquity and was mentioned by the name "nuts." The scientific name comes from the words «Jovis glans», meaning glans of Zeus. It is a tree, which is grown both for the tasty fruit, nut and for wood, which is highly resistant, appears no cracks and is used to manufacture furniture of very good quality, carpentry, woodcarving and gunsmith. Beyond that, however, it is also a tree that has many beneficial therapeutic properties, and this is due to the components it contains.

Walnut trees used to be cultivated from the old times in all the villages of the area and so there are several of them to date. In autumn, nuts ripen and the villagers, using minutes and far enough wood, the sticks, cane trees and collect their fruit.

Walnuts have a high nutritional value because they contain many vitamins, iron, manganese, calcium, cobalt, phosphorus etc. 

Most of the work on walnat health benefits is focused on their cardiovascular benefits. Several studies have emphasized the very favorable impact of walnuts on vascular reactivity, that is, the ability of our blood vessels to respond to various stimuli in a healthy manner.that is achieved through ample presence of antioxidant and anti-inflammatory nutrients, proper blood composition, correct balance in inflammation-regulating molecules, and proper composition and flexibility in our blood vessel walls. In fact, it has been found that walnuts can decrease LDL cholesterol, decrease total cholesterol, increased gamma-tocopherol, increased omega-3 fatty acids in red blood cells (alpha-linolenic acid), decrease aortic endothelin, improve endothelial cell function, decrease maximum platelet aggregation rate, decrease platelet activation, decrease C reactive protein (CRP), decrease tumor necrosis factor alpha (TNF-a).

Walnuts help reduce problems in metabolic syndrome. This consists of overlapping metabolic problems including excessive blood fats (triglycerides), high blood pressure, inadequate HDL cholesterol, and obesity (as measured by waist circumference, and/or body mass index).

Walnuts are rich in a wide variety antioxidant and anti-inflammatory nutrients. Anticancer research (breast and prostate cancer being the best studied) has shown that the antioxidant properties of walnuts help lower risk of chronic oxidative stress, and the anti-inflammatory properties help lower risk of chronic inflammation. Those are two types of risk, that, when combined, pose the greatest threat for cancer development.

Walnuts contain many anti-inflammatory nutrients including omega-3 fatty acids and  phytonutrients (tannins, phenolic acids, flavonoids, quinones like juglone and other anti-inflammatory phytonutrients). These anti-inflammatory benefits can overshadow the high-calorie and high-fat risk posed by walnuts, which is considered  a desirable food for support of weight loss and for prevention of obesity. Especially as obesity has been clearly identified by researchers as involving chronic, unwanted inflammation.
