Walnuts are perhaps the most famous tree nut of all and have been named the “Healthiest of All Nuts”. They are rich in plant-based fats and are a good source of the B-vitamins and many minerals.

Even though walnuts are one of the easiest foods to eat, they are also a powerful weapon against chronic diseases. Walnuts can be eaten by the handful as a snack, or in salads, soups, vegetable dishes, baked goods or smoothies.

Due to their uniquely high amounts of healthy fats and potent plant chemicals, recent studies are publishing evidence that walnuts can reduce brain stress, lower cholesterol, increase fertility in men, reduce inflammation, lower the risk of diabetes, strengthen the immune system, and help with insomnia because of the natural melatonin they contain.

Supporting the claim that walnuts are the healthiest nut is a recent study from the journal “Food and Function”. The researchers evaluated nine types of raw and roasted nuts and they found walnuts to contain the highest levels and quality of antioxidants.

An “antioxidant” is a substance in foods or vitamins that neutralizes the harmful effects of oxygen in the body. These “oxidative” effects contribute to aging and disease and can be caused by an unhealthful diet, air pollution, smoking, and also the normal processes of digestion and metabolism. Eating just seven walnut halves per day can be enough to obtain its many health advantages.

English walnuts offer powerful benefits to brain health. A study called “Role of Walnuts in Maintaining Brain Health with Age” was published in the Journal of Nutrition. The researchers wrote that walnuts not only reduce the inflammatory load on brain cells, but they also improve communication and connection between the brain cells themselves – helping to maintain good brain health with increasing age.

For a healthy heart and long life, walnut health benefits have been shown to decrease the risk of cardiovascular disease and also extend life spans in general. Walnuts contain the amino acid l-arginine, which offers protective benefits for the heart. A quarter cup of walnuts contains about 1,130 milligrams of l-arginine. The American Journal of Clinical Nutrition reviewed 13 heart studies and found that the people eating walnuts benefited from a significant decrease in overall cholesterol and had major benefits in the quantity of antioxidants available to them.

Walnuts can be a good sleep inducing food.  Eating a handful of walnuts before bedtime may be a good way to soothe sleeplessness and insomnia. Russel Reiter, Ph.D., a professor of cellular biology at the University of Texas says, “Relatively few foods have been examined for their melatonin content. Our studies demonstrate that walnuts contain melatonin, that it is absorbed when it is eaten, and that it improves our ability to resist oxidative stress caused by toxic molecules. Walnuts also contain large amounts of omega-3 fatty acids, which have been shown to inhibit certain types of cancer and to keep the heart healthy.”

Walnuts also contain 126 milligrams of magnesium per cup, which is 31% of the recommended daily intake. Regarding the use of minerals for insomnia, a study called “The Nutritional Relationships of Magnesium” reports that the classical sign of magnesium deficiency is falling asleep somewhat easily, but awakening frequently throughout the night, with individuals finding themselves tired even after several hours of sleep.

This natural health news is shared by Nutrition Breakthroughs, a provider of nutrition articles and effective natural remedies since 2001. Nutrition Breakthroughs makes the effective natural sleep aid Sleep Minerals II, with highly absorbable forms of calcium, magnesium and vitamin D in a softgel.

Regarding the use of Sleep Minerals II, Tammy M. of Meridian, Idaho says: “I was plagued with insomnia for five years and desperate for a breakthrough. Nothing has helped me more than Sleep Minerals — I’m so sold on them I could go door to door promoting them.  I’m 60 years old and have never slept so soundly.”

Sleep-inducing foods such as walnuts, tart cherry juice, and bananas are good things to include in one’s diet, as well as relaxing and effective forms of calcium and magnesium.

Four Research Studies Give Tips to Remedy Insomnia

Research scientists are discovering more and more ways to help people remedy insomnia and sleep better with simple nutrition and lifestyle improvements

Almost six out of ten Americans experience insomnia and sleep problems at least a few nights a week, as reported in a recent study done by the National Sleep Foundation.

Insomnia is defined as “An inability to fall asleep or remain asleep long enough to feel rested, especially when the problem continues over time.”

In an effort to combat this, as many as twenty-five percent of the people in the U.S. turn to sleep drugs. Because most people would prefer to avoid the side effects and addiction of sleep medications, research scientists have been busy studying nutritional and lifestyle approaches to getting better sleep.

Tip # 1 – We live in an electronics-oriented world, from computers, to cell phones, to texting, to reading books on tablets. These tools help increase our efficiency and ability to work and learn and communicate, but when it comes to getting good sound sleep, they can interfere.

One study from a university in New York found that exposure to light from electronic displays can suppress melatonin by about twenty two percent. Melatonin is a hormone made in the brain that helps to regulate the sleep/wake cycle. It is present in higher amounts at night. The researchers recommend shutting off all electronic devices at least one hour before bedtime and doing some relaxing things before bed.

Tip # 2 – Regarding sounder, deeper sleep resulting from taking walks, studies at the University of Arizona have found that walking more than six blocks a day at a normal pace significantly improves sleep at night for women.

Scientists suspect that walking helps to set our biological clock into a consistent sleep pattern. Walking can help increase “endorphins”, which are protein-like chemicals made in the brain that can have a relaxing effect, a pain-relieving effect, and can also reduce stress and increase well-being.

Tip # 3 – Sometimes hunger can strike at 2:00 or 3:00 in the morning and keep one awake. If this occurs, eat something with high protein such as turkey. Turkey contains tryptophan, which is an amino acid (a component of protein) that has a calming effect. According to Ray Sahelian, M.D., “Tryptophan ….can be converted at night into melatonin, the sleep-inducing hormone.”

As a note, concentrated tryptophan capsules are not recommended as they can create grogginess in the morning and take some time to wear off. Other foods that are high in tryptophan include nuts, seeds, chicken, fish, oats, beans, lentils, and eggs.

Tip # 4 – When taking natural sleep aids, it’s good to remember that each person is a unique individual and doing some experimenting with the dosage can be instrumental in achieving success. At first, err on the side of taking too little rather than too much. Another thing to keep in mind is that natural aids are not drugs and they may not work immediately with the first dose or even the first few doses. It can take up to a couple weeks to see results.

James F. Balch, M.D., author of Prescription for Nutritional Healing, writes: “A lack of the nutrients calcium and magnesium will cause you to wake up after a few hours and not be able to return to sleep.”

In one study published in the European Neurology Journal, researchers found that calcium levels in the body are higher during some of the deepest levels of sleep, such as the rapid eye movement (REM) phase. In the study, taking calcium restored normal sleep patterns.

One example of a mineral-based sleep remedy is Sleep Minerals II from Nutrition Breakthroughs. This sleep aid contains highly absorbable forms of calcium, magnesium and vitamin D. The ingredients are delivered in a softgel form with healthy carrier oils, making them more easily assimilated than capsules or tablets and providing a deeper, longer-lasting sleep.

Richard P. of Parkville, Maryland says: “The Sleep Minerals are making quite a difference. I was regularly waking up at around 3:00 a.m. and after a few days use my sleep improved quite a lot. I wake up once a night to go to the bathroom, but the great thing is, I then fall back asleep and sleep several more hours. This has been a great improvement.”

In summary, take the tips of recent research studies and take a walk each day, put the computers and cell phones away an hour before bedtime and do something relaxing, keep a high-tryprophan snack next to your bed at night, and use an effective form of calcium and magnesium before bed for a deeper, longer night’s sleep.
