Walnut Diet for Improvement of the Endothelial Function

Endothelial dysfunction, which is an early event in the development of vascular disease, is commonly associated with atherosclerosis and its risk factors. Various recent studies show that coronary endothelial dysfunction predicts CAD events in the near future. Vascular reactivity can be improved by dietary factors such as marine n-3 fatty acids, and antioxidants. To test the hypothesis that walnut intake would improve endothelial function, the scinetists performed a randomized, crossover feeding trial by substituting a walnut-enriched diet for a healthy Mediterranean-type diet for effects on brachial artery vasomotor function and circulating markers of endothelial activation.

Before the study, the general recommendations of a Mediterranean-type, cholesterol-lowering diet were reinforced in all eligible subjects, and baseline data were collected after 1 month. The self-reported nutrient contents of the baseline diet showed good adherence to dietary advice.

Of all participants randomly assigned to dietary intervention, 98% completed both study phases. The rest of them withdrew for personal reasons. According to participants’ reports and recounts of empty packages, compliance with walnut ingestion was 100%. Walnut consumption every day was tolerated by all subjects. The walnut meal in a background walnut diet was associated with significant improvement in brachial artery EDV. The walnut diet also attenuated endothelial activation, as suggested by the reduction in VCAM-1 levels.

Walnuts for Stress Reduction Diets

It`s well known that the nutrients in some types of nuts can help protect your body against the damaging physical effects of being stressed out. Some studies reveal that nuts rich in alpha-linolenic acid, like walnuts, had a heart-protective benefit during times of acute stress - which is known to cause cardiovascular strain.

(Also various sources indicate that almonds, because of their vitamin E, vitamin B and magnesium content can bolster your immune system when you're stressed)

A review of other studies about eating nuts found that people who added nuts to their diets and who replaced other foods with nuts lost more weight and reduced their waist sizes by more than half an inch.

Serving Walnuts

Although walnuts have always been considered a significant source of calories and nutrients for many centuries, nuts generally fell out of favor with health-conscious Americans during the low-fat diet that were popular in the 80s. Today, walnuts are recognized as a nutrient-dense source of protein, fatty acids, antioxidants and dietary fiber. As stated by the US Food and Drug Administration, eating a handful of nuts every day protects against heart disease.
As walnuts are commonly considered a concentrated source of calories and fat, and since many people do not estimate properly how many nuts are in one serving, the Food and Drug Administration of the United States recommends amount of individual portions that you can comfortably fit in the palm of your hand. While the US Food and Drug Administration suggests eating a handful of nuts daily to help reduce your risk of heart disease, the American Heart Association suggests consuming a small handful of nuts just four times per week.

Walnuts are Useful and Tasty

Walnuts are one of the most valuable and most helpful nuts known to man. They comprise many important vitamins, protein and omega 3 fatty acids. Precisely because of that nuts are convert in a valuable raw material that protecting human’s bones from fractures and injuries. Fatty acids have unique properties to strengthening health of bones and abbreviate the risk of traumas. They can be consumed as processed and raw. Walnuts are rich in askorbin, vitamins B1, B2, PP, carotene.

Kernels are recommended especially for people with stomach problems. Recent studies indicate that nuts reduce the amounts of cholesterol in the human body and they have a positive influence in the battle against many serious illnesses such as atherosclerosis and cardiovascular disease. It's good for people who are engaged primarily with mental activity because nuts can improve cerebral blood flow.

They are rich in vitamin E / vitamin-called anti-aging / and have good influence of physiological activity of the skin. Increasingly we hear about cosmetic products on walnut’s base. These nuts contain nutrients which help to heal scars and other skin pigmentation and give it shine. Some shampoos and hair conditioners are also made with walnuts - for smooth, shiny and healthy clumps. In addition, walnuts stimulate hair growth and reduce the risk of hair loss. Another feature typical for walnuts is their strong wood. It is has many and highly valued properties. Therefore finds a wide application in the production of furniture and interior design. Moreover, this kernel is a huge number of applications in cooking and home medicine.

Walnuts - The Healthiest Nut

Scientists recently told the American Chemical Society that walnuts contain the highest level of antioxidants compared to all the other nuts. Antioxidants are notoriously known for their help for protection of the body against disease.

Dr Vinson analysed the antioxidant levels of many different nuts and discovered that a handful of walnuts contained twice as many antioxidants as a handful of any other nut.

Previous researches have shown that regular consumption of small amounts of nuts could reduce the risk of heart disease and cancer, some types of diabetes and other health problems.

Generally, Walnuts are the healthiest of all the nuts and should be eaten more as part of a healthy diet, scientists from all over the world say.

Walnut Kernels Manufacturing Basics

Understanding walnuts’ engineering properties is important to facilitate and improve the design of processing equipment as well as harvesting, packaging and storage procedures and facilities.

During the process of extracting of the oil from the walnuts and its derivatives, the kernels undergo a series of unit operations.

At each step, various types of cleaning, grading, separation and oil-extraction equipment operate on the basis of the walnuts’ mechanical properties.

Therefore, detailed findings reported in some studies provide useful data to be used by engineers in the design of suitable walnut processing machines, thus enhancing process and quality control.

More about benefits of Walnuts in Diabetes

Nuts are recognized as having the potential to improve the blood lipid profile and, in cohort studies, nut consumption has been associated with a reduced risk of coronary heart disease. Randomized controlled trials of patients with type 2 diabetes have confirmed the beneficial effects of walnut kernels on blood lipids also seen in nondiabetic subjects, but the trials have not reported improvement in A1c or other glycated proteins. A study that has addressed this issue directly is the evaluation of this type of nuts consumption and risk of type 2 diabetes is the Nurses Health Study. According to it, consumption was inversely associated with risk of type 2 diabetes after adjustment for age, BMI, physical activity and alcohol and total energy intake, and mostly - diabetes.
