Eating This One Food Strengthens Beneficial Brainwave Frequencies

A new study by researchers at Loma Linda University Health has found that eating nuts on a regular basis strengthens brainwave frequencies associated with cognition, healing, learning, memory and other key brain functions.

An abstract of the study — which was presented in the nutrition section of the Experimental Biology 2017 meetings in San Diego, California, and published in The FASEB Journal — may be accessed online.

Nuts are one of the most nutrient-dense foods available, with an unrivalled unsaturated fatty acid, plant protein, fibre, mineral, vitamin profile. Nuts also contain other bioactive compounds such as phytosterols and phenolic antioxidants.

An impressive array of studies–large and small, from around the world–have now found that people who eat nuts regularly cut their risk of heart disease by as much as half, compared to those who rarely or never eat nuts. Eating nuts daily has been linked to lower all-cause mortality.

In the study — which is titled “Nuts and brain: Effects of eating nuts on changing electroencephalograph brainwaves”– researchers found that some nuts stimulated some brain frequencies more than others. Pistachios, for instance, produced the greatest gamma wave response, which is critical for enhancing cognitive processing, information retention, learning, perception and rapid eye movement during sleep. Peanuts, which are actually legumes, but were part of the study, produced the highest delta response, which is associated with healthy immunity, natural healing, and deep sleep.

The study’s principal investigator, Lee Berk, DrPH, MPH, associate dean for research at the LLU School of Allied Health Professions, said that while researchers found variances between the six nut varieties tested, all of them were high in very beneficial antioxidants, with walnuts containing the highest antioxidant concentrations of all.

Prior studies have demonstrated that nuts benefit the body in several significant ways: protecting the heart, fighting cancer, reducing inflammation and slowing the aging process. But Berk said he believes too little research has focused on how they affect the brain.

“This study provides significant beneficial findings by demonstrating that nuts are as good for your brain as they are for the rest of your body,” Berk said, adding that he expects future studies will reveal that they make other contributions to the brain and nervous system as well.

To gather research data on nut consumption and the brain, Berk — who is best known for four decades of research into the health benefits of happiness and laughter, as well as a cluster of recent studies on the antioxidants in dark chocolate — assembled a team of 13 researchers to explore the effects of regular nut consumption on brainwave activity.

In the introduction to the study, the team noted that different kinds of nuts contain different types of antioxidants. What they didn’t know, however, was whether different nut antioxidants had different modulatory effects on brainwave frequencies response.

To find out, Berk and his colleagues tested the effects of consuming nuts on frequency modulations inside the brain. He said the human brain produces five separate types of waves — delta, theta, alpha, beta and gamma — and that each wave produces its own frequency and occupies its own bandwidth. “Sort of like radio stations on a dial,” he said.

The team developed a pilot study using consenting subjects who consumed almonds, cashews, peanuts, pecans, pistachios and walnuts. Electroencephalograms (EEG) were taken to measure the strength of brainwave signals. EEG wave band activity was then recorded from nine regions of the scalp associated with cerebral cortical function.

Michael Samardzija, PhD, JD, associate vice president for research affairs, says Loma Linda University researchers have been discovering the health benefits of nuts for decades. He cites multiple studies conducted by Joan Sabate, MD, DrPH, and other researchers at the School of Public Health, which have demonstrated that nuts promote cardiovascular health, cancer prevention and healthy aging.

“These results coming from Dr. Berk’s research at the School of Allied Health Professions show that nuts can now be considered one of the superfoods helping to support brain health,” Samardzija said.

Broccoli Can Stimulate Brain Regeneration, New Research Suggests

Broccoli Can Stimulate Brain Regeneration, New Research SuggestsFor decades it was believed that brain regeneration was not possible. But an accumulating body of research now reveals that common foods such as broccoli contain compounds capable of stimulating the repair and renewal of nerve tissue.

Ever since Santiago Ramón y Cajal, the father of neuroscience, declared “nothing may be regenerated” in the adult brain, the idea that you can repair or regenerate damaged brain tissue was precluded by this central dogma. But compelling evidence for brain regeneration began to surface in the 1960’s with a report by MIT scientist Joseph Altman that the hippocampus of adult rats and guinea pigs and the cortex of cats indeed underwent a process termed neurogenesis,1  i.e. the growth and development of nervous tissue.

Pecan Nutrition Benefits the Hearth, Brain, Bones & More

Pecan nutrition - Dr. Axe

The savory taste of the pecan is worth a lot more than a delicious pie from grandma — this nut may help you stay healthy for a long time thanks to the wonders of pecan nutrition.

Pecan trees grow fiercely large and provide many of these scrumptious treats that have been shown to aid in weight loss, protect the body from diseases like atherosclerosis (hardening and narrowing of the arteries) and diabetes, and even improve brain health.

Although many people claim that a low-fat diet is the best way to live a healthy lifestyle, the healthy fats of pecan nutrition are powerful in the production of antioxidants, reduction of inflammation and simply provide a great-tasting addition to almost any dish.

Vitamin B3 Benefits Parkinson’s Disease

Individuals with a specific type of Parkinson’s disease (PD) could gain from increasing vitamin B3 (niacin) content in their diet, say British investigators.

B3 is one of eight B vitamins. It is also known as niacin (nicotinic acid) and has 2 other forms, niacinamide (nicotinamide) and inositol hexanicotinate, which have different effects from niacin.

Nicotinamide riboside has been linked to a number of surprising and powerful benefits. Foods high in Nicotinamide include Brewer’s Yeast, Sunflower Seeds, Raw Peanuts and Beets. Interestingly Beet Juice & Yeast have been shown to have remarkable cancer killing attributes. Possibly due to the sugars in the beets causing a beneficial form of fermentation to occur with the B vitamins in the Brewer’s Yeast.

Worldwide Studies Find Vitamin B ‘Significantly’ Reduces Symptoms of Mental Disorders

We cannot escape the reality that in developed nations, people are often overfed and undernourished. A growing body of literature links dietary choices to brain health and the risk of psychiatric illness. B vitamins are required for proper functioning of the methylation cycle, monoamine production, DNA synthesis, and maintenance of phospholipids such as myelin. A review of worldwide studies has found that add-on treatment with high-dose b-vitamins — including B6, B8 and B12 — can significantly reduce symptoms of schizophrenia more than standard treatments alone.

The research — on the effect of vitamin and mineral supplements on symptoms of schizophrenia was published in Psychological Medicine, one of the world’s leading psychology journals.

Vitamin B is a dietary powerhouse, boosting energy levels and enhancing performance of nearly every system in the body.

The connection between mental health and B12 deficiency is staggering and yet it appears screening is rarely carried out within any division of modern healthcare.

One Of The Most Perfect Foods Also Improves Cognition

One of the most perfect foods, low in calories, containing every single vitamin (A, B, D, E, K) except C, and nearly perfect in protein can also improve aspects of cognition, according to research that also concludes neither high intake of cholesterol or eggs are associated with an increased risk of dementia or Alzheimer’s disease.

The study, involving almost 2,500 Finnish men, aimed to test a suggested link between intakes of cholesterol (and eggs as a major source of dietary cholesterol) and cognitive decline in both the general population and in a group of people genetically ‘at risk’ of dementia.

Led by Maija Ylilauri from the University of Eastern Finland, the team found that a relatively high intake of dietary cholesterol, or eating one egg every day, was not associated with an increased risk of dementia or Alzheimer’s disease.

Best Foods for Boosting Brain Power

According to the Alzheimer’s Association, more than 5 million Americans suffer with Alzheimer’s disease and 1 of every 3 seniors dies with some form of dementia.1 Families may spend over $5,000 each year caring for a loved one, and it costs the U.S. $216 billion a year for Alzheimer’s and other types of dementia.

However, feeding your brain the right food isn’t just about preventing a disease in the future. Giving your brain the fuel it needs to function optimally may also improve your current cognitive function and creativity, making you more productive at work and at home.

Your brain needs the right fuel to nourish neurons, boost production of neurotransmitters and protect against damage and degeneration.

Unfortunately, some popular nutritional fads may have placed you at greater risk for damage to your neurons, without the additional heart health benefits and proponents of these dietary changes promised.

You may make a significant difference in your overall health and reduce your risk of dementia or Alzheimer’s disease when you purposefully include the foods your brain needs to function and detoxify.
