12 Health Benefits of Walnuts
1 Source of omega-3
Although walnuts contain 65% fat (including omega-3 alpha-linolenic acid (ALA)), they reduce blood fat. Only 4-7 walnuts contain 2,5 grams of omega-3s, which is more than 2 times the minimum requirement for an adult. [2].

The polyunsaturated fatty acids contained in the nut along with minerals are recommended for the prevention of hypertension, atherosclerosis and other diseases of the heart and blood vessels.
2 Improves memory and brain function
In a 10-month study of Alzheimer’s disease, mice fed 6–9% of calories from walnuts (equal to 28–45 g per day in humans) had significant improvements in learning, memory, and anxiety reduction compared to a control group without walnuts. [4]. In addition, there are human studies that support the role of walnuts in maintaining brain health with age. [5].
3 Reduces blood cholesterol levels
Walnut kernels increase high-density lipoprotein (HDL) and lower bad cholesterol levels. For example, in a recent study in 194 healthy adults, eating 43g of walnuts daily for 2 months resulted in a 5% reduction in total cholesterol, a 5% reduction in LDL levels, and a 5% reduction in triglycerides. What’s more, those people who consumed walnuts also experienced a nearly 6% decrease in apolipoprotein-B. And as you know, high levels of apolipoprotein-B are a major risk factor for heart disease. [6].

4 Source of Powerful Antioxidants
Walnuts have higher antioxidant activity than any other common nuts. This activity comes from vitamin E, melatonin, and plant compounds called polyphenols, which are especially high in walnut skins. [7], [8]. A small study in healthy adults found that eating walnuts prevented oxidative damage to “bad” LDL cholesterol after meals, while eating refined fat did not. This is beneficial because oxidized LDL tends to accumulate in arteries, causing atherosclerosis. [9]. In addition, walnuts contain exactly the form of vitamin E (in the form of gamma-tocopherol instead of the widely available alpha-tocopherol), which is of particular benefit to the human body and provides reliable protection to the heart.
5 Reduces inflammation in the body
The polyphenols in walnuts help fight oxidative stress and inflammation. A subgroup of polyphenols called ellagitanins deserves special attention. Beneficial bacteria in the gut convert ellagitannins into compounds called urolithins, which have been shown to protect against inflammation. And coupled with omega-3, magnesium and the amino acid arginine, walnuts significantly reduce inflammation in the body.
6 Cancer Prevention
As noted earlier, walnuts are rich in polyphenolic ellagitannins, which are converted by our gut bacteria into urolithin. Urolithins have anti-inflammatory properties, which may be one way walnuts protect against bowel cancer. What’s more, urolithins have hormone-like properties that allow them to block hormone receptors in your body. Due to this property, the risk of hormonal cancer, especially breast cancer and prostate cancer (in women and men, respectively), is reduced. Including walnuts in the diet reduces the risk of these types of cancer [10].

7 Strengthens bones and joints
Walnuts contain in their biological composition a number of anti-inflammatory substances that contribute to the prevention of obesity, weight loss and restoration of bone health.
8 Improves sleep
This product contains melatonin available to the body – the main regulator of sleep, body restructuring for dark and daylight hours, daily rhythm and other vital processes.
9 Help with diabetes
Thanks to fatty acids and vitamin E, walnut is an excellent prevention of type 2 diabetes. The study involved 100 people with type 2 diabetes. The control group was given 1 tablespoon of cold-pressed walnut oil every day for 3 months (while continuing with regular diabetes medications and a balanced diet). As a result, it was possible to reduce fasting blood sugar levels by 8%, compared with the placebo group. [11].
10 The benefits for the cardiovascular system
Walnuts increase vascular reactivity, due to which blood vessels easily and quickly adapt to changes in the environment. In addition, the walnut restores the correct composition of the blood, and a sufficient amount of nutrients, anti-inflammatory substances and antioxidants ensure the flexibility of the walls of blood vessels. By including walnuts in the daily menu in the amount of 30-50 grams, you can significantly increase the stability of the cardiovascular system and its flexibility. [12].
11 Improves bowel function
Walnuts normalize the microflora and relieve dysbacteriosis. A study was conducted involving 194 healthy people. They ate 43 grams of walnuts every day for 8 weeks and saw an increase in beneficial bacteria in their gut compared to when they didn’t eat walnuts. [13]
12 Reduces blood pressure
Some research suggests that eating walnuts may help lower blood pressure. However, other studies have refuted this effect. Thanks to large-scale studies in which 7500 adults participated, it was possible to confirm the positive effect of walnuts on blood pressure. Thanks to omega-3 acids, not only blood pressure improves, but also the entire cardiovascular function in general. Despite the fact that the pressure has decreased slightly, walnuts in any case should be included in your diet! [14].
Benefits for women
1 Helps control weight
Metabolic syndrome includes a number of problems that have time to accumulate in the body: high blood pressure, excess fat and cholesterol in the blood, obesity. Daily use of four walnuts for two to three months helps to reduce metabolic syndrome.
Women aged 50 and older who consume at least two servings of walnuts a week are more likely to be free of age-related diseases compared to those who don’t, according to a new study.
Benefits for men
Enhances potency. Due to its rich composition, such a nutritious product is incredibly beneficial for all men. It can be used as a unique therapeutic agent for the treatment of a wide variety of health problems. It has been proven that not only zinc, but also calcium and magnesium contained in walnuts are of particular value for all men. They help increase the synthesis of the male sex hormone. The level of testosterone provides a high level of potency. Essential oils, fiber and tannins instantly restore physical strength after overwork.
Walnuts increase a man’s sexual strength, normalize the development of male genital organs, and even increase sperm production. You need to eat about 10-15 nuts a day to be a healthy and full-fledged man.
Recipe with figs, prunes, raisins and dates. Even in the old days, walnuts were the basis for the preparation of products that increased sexual strength in men. For example, it was possible to cook the following: dry figs or prunes, pitted raisins and dates – all three ingredients are 100 grams each. Optionally, you can add the juice of 1 lemon. Walnut kernels need to take 300 grams. All these ingredients should be crushed and mixed. The prepared mixture is stored in the refrigerator. You need to take the medicine in the morning and in the evening, 1 tablespoon. But you can also take 2 tablespoons at once to enhance the effect.

Nursing mothers are advised to eat no more than two walnut kernels per day.
How many walnuts should you eat per day?
Since nuts are high-calorie foods, it is important to use them in moderation. When walnuts are included in the diet, the daily amount of food consumed should not increase. Thus, they try to replace nuts on the menu with those foods that contain saturated fats (for example, meat and cheese).
To maintain your health at the proper level, it is enough to consume 30 g of walnuts per day – this is 5-7 full nucleoli or 10-14 halves.

Как выбрать хорошие орехи?
Грецкие орехи со светлой кожицей имеют большую ценность, нежели с темной. Это стоит учитывать при планировании покупки орехов в очищенном виде. Если же вы берёте орехи в скорлупе, стоит отдать свой выбор тем экземплярам, которые кажутся вам тяжелее своего размера. Скорлупа должна быть без пятен, проколов или трещин, в противном случае орех уже давно одолели вредители, и есть его далеко небезопасно.
Никогда не берите с прилавка старые орехи, выбирайте максимально свежий продукт. Абсолютно всё равно, покупаете ли вы грецкие орехи в упаковке или на развес, главное, чтобы они не выглядели сморщенными или резиновыми. При возможности удостоверьтесь, что орехи не имеют прогорклого запаха, ведь несвежий продукт вместо пользы принесёт вашему здоровью только вред.
