Oftentimes, the simplest foods are best for your health, and this is certainly the case for nuts, in which Mother Nature has crafted a nearly perfect package of protein, healthy fats, fiber, plant sterols, antioxidants, and many vitamins and minerals. Crafted and packaged with the very best of bioactive components the walnut is a nut of wonder among its peers.
One-quarter cup of walnuts, for instance, provides more than 100 percent of the daily recommended value of plant-based omega-3 fats, along with high amounts of copper, manganese, molybdenum, and biotin. Some of the most exciting research about walnuts includes:

1. Cancer-Fighting Properties:
Given the wide variety antioxidant and anti-inflammatory nutrients found in walnuts, it’s not surprising to see research on this tree nut showing measurable anti-cancer benefits. The antioxidant properties of walnuts help lower risk of chronic oxidative stress, and the anti-inflammatory properties help lower risk of chronic inflammation, and it is precisely these two types of risk, that, when combined, pose the greatest threat for cancer development. Prostate cancer and breast cancer are the best-studied types of cancer with respect to walnut intake, and their risk has been found to be reduced by fairly large amounts of walnut consumption.

2. Heart Health:
Walnuts contain theamino acid l-arginine, which offers multiple vascular benefits to people with heart disease, or those who have increased risk for heart disease due to multiple cardiac risk factors.
If you struggle with herpes, you may want to avoid or limit walnuts, as high levels of arginine can deplete the amino acid lysine, which can trigger herpes recurrences.
Walnuts also contain the plant-based omega-3 fat alpha-linolenic acid (ALA), which is anti-inflammatory and may prevent the formation of pathological blood clots. Research shows that people who eat a diet high in ALA are less likely to have a fatal heart attack and have a nearly 50 percent lower risk of sudden cardiac death. Eating just four walnuts a day has been shown to significantly raise blood levels of heart-healthy ALA,and walnut consumption supports healthful cholesterol levels.

Separate research showed that eating just one ounce of walnuts a day may decrease cardiovascular risk,and among those at high cardiovascular risk, increased frequency of nut consumption significantly lowers the risk of death.
3. Rare and Powerful Antioxidants:
Antioxidants are crucial to your health, as they are believed to help control how fast you age by combating free radicals, which are at the heart of age-related deterioration.
Walnuts contain several unique and powerful antioxidants that are available in only a few commonly eaten foods. This includes the quinone juglone, the tannin tellimagrandin, and the flavonol morin.
Walnuts contain antioxidants that are so powerful at free-radical scavenging that researchers called them “remarkable,”and research has shown that walnut polyphenols may help prevent chemically-induced liver damage.
In another study, researchers found that nuts, especially walnuts, have potent antioxidant powers. Walnut polyphenols had the best efficacy among the nuts tested and also the highest lipoprotein-bound antioxidant activity. The researchers concluded:
“Nuts are high in polyphenol antioxidants which by binding to lipoproteins would inhibit oxidative processes that lead to atherosclerosis in vivo. In human supplementation studies nuts have been shown to improve the lipid profile, increase endothelial function and reduce inflammation, all without causing weight gain.”

4. Weight Control:
Adding healthful amounts of nuts such as walnuts to your diet can help you to maintain your ideal weight over time. In one review of 31 trials, those whose diets included extra nuts or nuts substituted for other foods lost about 1.4 extra pounds and half an inch from their waists. Eating walnuts is also associated with increased satiety after just three days.
5. Boosts sperm quality:
Eating 2.5 ounces of walnuts per day improves semen quality in healthy young men, researchers say. According to a study by UCLA researchers, eating 75 grams of walnuts a day improves the vitality, motility, and morphology of sperm in healthy men aged 21 to 35

6. Brain Health:
Walnuts contain a number of neuroprotective compounds, including vitamin E, folate,melatonin,omega-3fats, and antioxidants. Research shows walnut consumption may support brain health, including increasing inferential reasoning in young adults.One study also found that consuming high-antioxidant foods like walnuts “can decrease the enhanced vulnerability to oxidative stress that occurs in aging,” “increase health span,” and also “enhance cognitive and motor function in aging.”
7. Diabetes:
The beneficial dietary fat in walnuts has been shown to improve metabolic parameters in people with type 2 diabetes. Overweight adults with type 2 diabetes who ate one-quarter cup of walnuts daily had significant reductions in fasting insulin levels compared to those who did not, and the benefit was achieved in the first three months.

8. Sleep Promotion:
A final fascinating aspect of walnuts and their potential health benefits involves melatonin (MLT). MLT is a widely-active messaging molecule in our nervous system, and very hormone-like in its regulatory properties. MLT is critical in the regulation of sleep, daily (circadian) rhythms, light-dark adjustment, and other processes. It has also been found to be naturally occurring within walnuts. Average melatonin (MLT) content of walnuts is approximately 3.6 nanograms (ng) per gram (g), or 102ng/ounce. Other commonly eaten foods—for example, cherries—have also been found to measurable amounts of MLT. Researchers are not yet sure how everyday intake of MLT from walnuts is involved in our health, but several study authors have hypothesized about the MLT in walnuts as playing an important role (along with other walnut nutrients) in the anti-cancer benefits of this unusual food.
9. Anti-inflammatory Properties:
Walnuts are unique in their collection of anti-inflammatory nutrients. These nutrients include omega-3 fatty acids; phytonutrients including tannins, phenolic acids, and 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, and that’s exactly what they have done in an increasing number of research studies involving risk and/or treatment of obesity.
10. Hair Growth:
Walnut is a good ‘hair food’ too. This is because walnuts containbiotin (vitamin B7)that helps strengthen hair, reduce hair fall and improve hair growth to certain extent. In addition to walnuts, you can try thesefoods to prevent hair loss.
The form of vitamin E found in walnuts is somewhat unusual, and particularly beneficial. Instead of having most of its vitamin E present in the alpha-tocopherol form, walnuts provide an unusually high level of vitamin E in the form of gamma-tocopherol. Particularly in studies on the cardiovascular health of men, this gamma-tocopherol form of vitamin E has been found to provide significant protection from heart problems.
11. Improved Blood Flow:
Walnuts supply the body with a good amount of the amino acid L-ARGININE. It’s converted to nitric oxide, a compound that causes blood vessels to dilate, improving the blood flow to all your muscles.
