  • Make Sure You’re Not Short Of This Important Mineral

    It’s a vital nutrient, a component of over 300 enzyme systems, involved in many body functions. It’s crucial for protein synthesis, reproduction and sexual development, healthy skin, the immune system, wound healing and the senses of taste, smell and sight.

    It’s also vitally important for proper cognitive function. A deficiency in this mineral has been linked with memory loss and Alzheimer’s disease. Keep reading for the full story. . .

    Hidden Constipation Syndrome –
    Have You Got It?

    A recent study reports that more than half of patients – 62 percent – have colons plugged up with layers of filthy, decayed fecal matter. . .

    . . .even though 80 percent had bowel movements every day without straining!

    Colon autopsies show it and now studies have proven it. Even if you have a regular, daily bowel movement, you may possibly have pounds of hardened, toxic, bacteria-laden waste matter stuck in your intestines!

    Breakthrough study results from the prestigious Department of Organ Surgery and Gastroenterological Clinic in Elsinore, Denmark, reveal that millions of people unknowingly have these large “fecal reservoirs” – which back up your entire colon and rectum.

    And no synthetic laxatives or enemas can get this toxic, rotting mess out of you!

    can get rid of this deadly threat to your health and well being.

     

    Zinc Can Help You Think

    The mineral I’m talking about is zinc. It’s the brain’s most abundant trace metal.

    Although zinc has been used in the treatment of depression, anorexia and schizophrenia, only recently have scientists uncovered the many crucial roles it plays in neurological health.

    It acts as an antioxidant to stop unhealthy changes or death of brain cells.

    It helps to prevent dysfunction of the mitochondria – the cells’ energy factories – in the hippocampus. The hippocampus is one of the first areas of the brain to suffer in Alzheimer’s disease. It plays an essential role in learning and memory. And its levels of zinc are among the highest found in the brain.

    Communication between brain cells in the hippocampus depends on zinc. High levels of zinc are found in compartments of neurons called vesicles. A zinc pump called ZnT3 fills these up at the synapse, allowing them to fire and communicate with other nerve cells.

    Enzymes that maintain protein stability and prevent the aggregation of beta amyloid proteins are zinc dependent. You probably recall that beta-amyloid proteins are the main component of plaques found in Alzheimer’s. Zinc is also needed for a gene called Tsa1 that likewise prevents proteins from clumping together.

    Zinc protects against the overactivity of chemicals that can damage nerve cells and also prevents too much copper from entering the brain. High copper levels can have a number of damaging effects on your thinking ability (See Issue #20).

     Needed For Healthy Cognitive Function

    Much of the evidence concerning zinc’s effects on the brain have come from laboratory and animal research. However, there are a number of human studies that support its role in brain health.

    In a study which induced acute zinc deficiency in adults, a few hallucinated, some became paranoid and others suffered with depression.

    In two studies of volunteers who were fed zinc-deficient diets, participants in the first had less ability to memorize numbers and carry out perceptual tasks. In the second study, participants had decreased ability in psychomotor, perceptual, memory and spatial tasks.

    The brains of twelve elderly nuns were examined after death. The number of plaques correlated with serum zinc concentrations taken a year before they died. The less zinc in the blood, the more plaques in their brains.

    Alzheimer’s patients are known to be zinc-deficient based on their blood serum levels. This was first demonstrated in 2010. Although serum zinc declines with aging, there is a much more rapid decline in victims of Alzheimer’s disease. Amyloid plaques strongly bind to zinc, making the metal less available to carry out its functions.

    Recently a six month trial was carried out that included 14 people over the age of 70 suffering from mild to moderate Alzheimer’s disease. They were given 150 mg of zinc a day. This is several times what conventional medicine considers a high dose of zinc.

    The supplement significantly increased serum zinc and protected against loss of cognitive ability. This was not the case in the placebo group. They continued to show significant cognitive loss.

    Low Zinc Levels are Common – and Overlooked

    Zinc is known to have many vital roles in the mind and body. You don’t want to be deficient in this mineral.

    The recommended daily allowance for adults is 8mg for women and 11mg for men. Even though these levels are quite modest – in fact, they’re absurdly low — the National Health and Nutrition Examination Survey found 35% – 45% of those over 60 had intakes below 6.8mg (women) and 9.4mg (men).

    Best food sources of zinc are meat, seafood and poultry. Nuts, whole grains and most dairy products are good vegetarian sources. Oysters are famously high in zinc but I don’t think it’s very practical to eat them often.

    Because this mineral is so important, and as we grow older we’re less able to utilize it, a daily supplement containing at least 15mg is recommended. I take 50 mg five days a week and 15 mg the other two days. Zinc becomes toxic at high levels.

    The best and safest way is to have blood work done under the guidance of an alternative or integrative doctor, and adjust your nutrient intake as needed. That way you don’t have to guess whether you’re deficient – or whether your levels are so high they’re toxic.

    The blood test results can be surprising. A couple of years ago I found I had incredibly high levels of selenium – also toxic in large amounts. I still have no idea why my levels got so high, but I was able to stop taking selenium supplements and achieve a healthy level.

    Brain Formulas are Nice, But…

    I see any number of supplement companies advertising various formulas containing herbs and nutrients to support your brain and memory. I don’t recall any containing zinc. And indeed I wouldn’t recommend putting zinc in a memory formula because so many people are likely to be taking zinc in other supplements – and there is some danger of taking too much.

    What’s more, some of these memory formulas have so many ingredients they don’t provide a therapeutic dose of each one. There’s often just enough of ingredient “X” to allow the maker to say it’s there and put it on the label – “pixie dust” as it’s called by a supplement expert I know. The advertising leads you to think the formula is providing a therapeutic dose of whatever it is, but it’s not so.

    Meaning: You can’t count on a so-called memory formula to contain everything you need. Our recommended supplement company, Green Valley Natural Solutions, has decided to take a different tack. It has started putting out a line of memory supplements with only one or two ingredients – but there’s enough of whatever it is to provide you with a full, therapeutic dose (for example, our new offering Brain Vitality Plus.)

    This is generally what I do in my own supplement plan – not only for memory supplements but for all my supplements. I take each vitamin, each mineral and each herb in a separate pill. That way I can decide on the dose for each one and also purchase the highest quality form of each one.

    I help formulate Green Valley’s supplements myself, so keep an eye out and kindly consider our offerings. They’re trying to bring you the best.

  • Why the Brain Disease Epidemic is Only Going to Get Worse

    The 2006 science fiction movie Idiocracy depicts a future United States populated by people with IQs so diminished they can be classified, as the movie’s title implies, as idiots.

    And while the movie is a comedy, the frightening truth is that health trends playing out in the U. S. today are making such a development ever more likely. Your future brain health is in danger, and you need to protect the organ between your ears from the memory-threatening ills that are reaching epidemic proportions in North America.

    Here’s a rundown on some of the worst threats. . .

    This Doctor Blunder is
    Condemning Millions of
    People to Joint Pain

    . . .maybe including you!

     

    Stanford University scientists have made a startling new discovery about the true cause of joint pain – and it’s turning the medical world upside down.

    Everything doctors thought they knew about joint pain is DEAD WRONG! And they’ve been treating it in the wrong way.

    That’s the bad news. The GOOD NEWS is that the actual cause of most joint pain is easy to treat. You just have to know what it is.

    Here’s your chance to experience relief like you’ve never known before. ADDED BONUS: The same overlooked cause of joint pain also contributes to dementia and memory loss. So click here for the full story.

     

    Scary Images

    According to a studyi at the Icahn School of Medicine at Mount Sinai that reviewed brain imaging research during the past 30 years, a number of common conditions can compromise your brain function. And the damage can occur before you notice any memory problems or loss of thinking ability.

    These harmful conditions include:

    • High blood pressure: Can lead to a reduction of brain size, abnormalities in brain fibers, hampered blood flow to the brain and disrupted brain activity that is supposed to be synchronized between separate brain areas.
    • Diabetes: Interferes with the proper formation of brain fibers, limits blood flow to the brain and alters functions of brain activities meant to be coordinated between different regions.
    • Obesity: Leads to brain shrinkage while being associated with less blood flow to the brain and reduced brain metabolism.
    • High levels of total cholesterol and LDL (bad) cholesterol: Leads to a smaller brain and the interruption of brain fiber connections. High triglycerides (blood fats), create a risk of restricted blood flow to the brain. High cholesterol levels can interfere with brain cell energy functions.
    • Smoking: Leads to brain shrinkage and restricted blood flow.
    • Metabolic Syndrome: This condition (characterized by high blood pressure, extra body fat around the waist, elevated blood sugar and abnormal cholesterol) increases the risk of silent brain infarcts (SBIs) – strokes that damage the brain even though the victim may not notice any symptoms.

     The Shrinking American Brain

    Collectively, these conditions now impact a frighteningly large number of Americans. About 30 million Americans have diabetes. By 2050, this number is expected to soar to something like 85 million.ii More than a third of Americans are now obese, a total of about 80 million people.iii

    One thing you can do immediately to protect yourself: Eat less. On average, each American eats 25 percent more calories than individuals did 30 years ago.

    And the extra calories may hurt our brains even when they don’t lead to weight gain.

    A lab studyiv at New York University’s Langone Medical Center shows that consuming fewer calories promotes brain health and keeps the brain younger.

    “Our study shows how calorie restriction practically arrests gene expression levels involved in the aging phenotype — how some genes determine the behavior of mice, people, and other mammals as they get old,” says researcher Stephen D. Ginsberg, a neuroscientist.

    Another important brain defense: Stay away from processed food. Researchv at Boston Children’s Hospital shows that processed foods like soft drinks, cookies and chips – far from satisfying your hunger — make you likely to feel even hungrier and to put on weight.

    “(Our) findings suggest that limiting high-glycemic index carbohydrates like white bread and potatoes could help obese individuals reduce cravings and control the urge to overeat,” says researcher David Ludwig.

    If you take a peek at movies from the 1960s or before, you’ll see how much thinner people were back then because they ate so much less and didn’t indulge in so much processed food.

    What you can’t see: Their brains also were in better shape. Yours can be too, if you restrain your eating.

  • Avoid These Cholesterol-Raising, Brain-Shrinking Memory-Zappers that Lie Hidden in Your Food

    Many popular foods contain man-made chemicals that promote weight gain, increase ‘bad’ cholesterol and raise the risk of heart disease. In fact, there’s only one molecule of difference between these “foods” and plastic.

    Studies now show they’re a disaster for the brain, too. Just a few grams a day can harm our memories and increase the risk of Alzheimer’s. They can even make you depressed. Keep reading for the full story. . .

    This “Forbidden” Food
    Super-Charges Your Brain

     

    It’s being called a “silent epidemic”…

    A brain health crisis already growing faster than Alzheimer’s disease or dementia…and affecting the memory and cognitive ability of Americans as young as 40.

    Over the next decade, the U.S. government will spend more than $3 billion to study this threat.

    But you know what? They don’t need to spend the $3 billion because the major cause of memory loss has already been identified. Yet almost no one knows about it.

    Millions of people are losing their memories and seeing their brain health go downhill because nine out of ten of us don’t consume enough of vital nutrients we need for healthy brains. And when it comes to one of the most important nutrients of all…

    …we don’t get enough because doctors tell us NOT to eat the foods that happen to be richest in this “missing ingredient for good brain health”!!

    That’s right, the very food you need most for memory and cognitive health is a forbidden food! It’s a national scandal… but it’s also an opportunity for you to save your brain and improve your memory like you wouldn’t believe…

    Click here and I’ll tell you the full story…

     

    These nasty chemicals are called trans fats. Although research proves they have devastating effects in small amounts, they’re still found in many everyday foods.

    Trans fats are created by bubbling hydrogen into unsaturated vegetable oils at very high temperatures. This creates changes in their molecular structure such that the oils become solid.

    Margarine is an example of a trans fat. It’s manufactured by taking an oil such as corn oil that is liquid in its natural state, and turning it into a solid by saturating its molecules with hydrogen atoms.

    Trans fats greatly increase the shelf life of foods and can also improve their texture and flavor. They’re easier for the food industry to deal with compared to fats like butter that are naturally saturated (and solid), but subject to spoilage.

    Coconut oil is another natural saturated fat and it’s not – as far as I know – prone to spoilage. But the food industry prefers trans fats that come out of a lab, and those are what you find in processed foods.

    Trans Fats Shrink The Brain

    In 2012, Dr. Gene Bowman and his research team at Portland’s Oregon Health and Science University studied 104 people with an average age of 87 – quite advanced in years. The researchers took blood samples, put the participants through thinking and memory tests, and scanned their brains.

    They found those with the highest levels of trans fats in their blood scored lowest on the cognitive tests and had the smallest brains. Considering that brain shrinkage is one of the hallmarks of Alzheimer’s, this was an important finding.

    Dr. Bowman said, “We know that in Alzheimer’s disease the brain shrinks at an accelerated pace as the disease and pathology spreads to certain parts of the brain, but if you have a larger brain and more brain tissue, you might have a reserve to handle that pathology better.”

     

    Doubles The Risk of Alzheimer’s

    An earlier study analyzed food questionnaires filled out by 815 Alzheimer’s-free people aged 65. After four years, 131 of them developed dementia. The researchers found that those with the highest trans fat intake were twice as likely to develop the condition compared to those with the lowest intake.

    According to the leader of the study, Martha Morris of Rush University Medical Center in Chicago, “The increase in the risk of Alzheimer’s occurred with fairly low levels of trans fat intake – 2.3 grams a day.”

    That’s less than a tenth of an ounce.

    Reduces Memory Even In Younger Men

    In November, 2014, Dr. Beatrice Golomb of the University of California, San Diego, School of Medicine presented the latest findings of her research group at a medical conference in Chicago.

    A previous study from her team found that trans fats could affect mood, making people either depressed or more aggressive.

    For the new study a thousand healthy men 45 or under were asked to complete a dietary survey and then undergo a memory test in which they had to recall whether words shown to them on 104 cards were new or had already appeared on a previous card.

    For each additional gram of trans fat consumed, 0.76 fewer words could be recalled. Although that doesn’t sound a great deal, those with the highest trans fat intake consumed 15 grams a day. That represents a drop of 11.4 words, or a fall of over 10% in memory ability compared to those with the lowest intake of trans fats.

    Dr. Golumb said, “While trans fats increase the shelf life of foods, they reduce the shelf life of people.”

    Trans Fats Are Found Everywhere

    Trans fats are found in processed, packaged, fried and fast food, margarine, vegetable shortening, biscuits, cookies, crackers, cakes, potato chips, baked goods, snack foods, frozen pizza and coffee creamers.

    If unsure whether a food contains trans fats, look on the label. If you see the words hydrogenated, margarine or shortening then you know it does.

    And don’t be fooled by the “no trans fat” label that might be stamped on the front.

    A manufacturer can make this claim if the food contains less than half a gram of trans fat per serving. The food manufacturer decides what quantity of the product is a serving. It should come as no surprise that the serving size can be ridiculously small, with most people needing to consume lots of servings at a time to feel satisfied. (Potato chips are a good example – the food makers define a “serving” as five or six chips.)

    The message from these studies is stay clear of trans fats. Keep well away if you want to preserve the health of your brain and your heart.

  • Make Sure You Get Enough of the “Brain Vitamin”

    (Cuts Your Risk of Dementia
    and Memory Loss by Half)

    There’s an ordinary, everyday vitamin supplement that’s so important for preserving brain health, if it were a drug, pharmaceutical companies would charge you a small fortune to buy it at your local pharmacy.

    It cuts your risk of dementia and memory loss in old age in half. And that’s just for starters. . .

    Diseases like heart disease, cancer, diabetes and Alzheimer’s can be passed down from generation to generation.

    But that doesn’t mean you should be a sitting duck and wait for disease to strike.

    Recent scientific breakthroughs now allow you to switch “off” the bad genes you inherited – and drastically lower your risk of disease.

    If you suffer cardiac arrest, this vitamin improves your chances of retaining good brain function sevenfold. (Oh, and while we’re on the subject, it also boosts your chance of surviving the heart attack.)

    The vitamin also increases brain power in middle-age.

    You already know it well as vitamin D.

    Almost Everyone is Deficient

    Despite this vitamin’s importance, experts estimate that 70 percent of us aren’t getting enough. I would say the 70 percent figure is conservative. In a moment, I’m going to share with you some shocking news about how much vitamin D you should be taking, and I guarantee you that even good alternative doctors are NOT up to speed on the latest research.

    First, let’s look at the incredible benefits those high vitamin D levels can give you…

    Researchers at the University of Exeter Medical School in the United Kingdom conducted an international studyi. The results show that if you enter old age with a significant vitamin D deficiency you run a doubled risk of dementia and Alzheimer’s disease compared to people who have adequate amounts of the vitamin.

    The scientists analyzed data from senior Americans who were taking part in research called the Cardiovascular Health Study. People in the study who were only moderately vitamin D deficient ran a 53 percent increased risk of developing dementia of any sort as they aged. The people who were severely lacking in vitamin D were at 125 percent greater risk – far more than a double.

    Parallel findings were found for Alzheimer’s disease: People who were moderately deficient were 69 percent more vulnerable to this type of memory problem, and the risk of the severely deficient grew by 122 percent.

    According to researcher David Llewellyn: “We expected to find an association between low Vitamin D levels and the risk of dementia and Alzheimer’s disease, but the results were surprising – we actually found that the association was twice as strong as we anticipated.”

     Protect Your Heart and Brain

    Researchers in South Korea looked into the effects of vitamin D on people who suffer cardiac arrest (when the heart’s steady rhythm is interrupted and the heart has to be restarted). The study found an even more impressive level of protection.ii

    Cardiac arrest interrupts the blood supply to the brain, threatening the survival of brain cells. But having sufficient vitamin D exerted strong protection against disruption of brain cell function. “Vitamin D deficiency increased the risk of poor neurological outcome after sudden cardiac arrest by sevenfold,” notes researcher Wi Jin.

    He also reports that six months after their cardiac arrests, a third of the vitamin D deficient patients had died. None of the people who had enough vitamin D in their bodies passed away during that time.

    Brain Power

    Meanwhile, if you’re trying to improve your brain power in middle age, research at the University of Manchester in England shows that higher levels of vitamin D improve your intellectual abilities. This studyiii looked at how well more than 3,300 European men in their 40s, 50s, 60s and 70s performed on tests of their mental focus and processing of information.

    “Interestingly, the association between increased vitamin D and faster information processing was more significant in men aged over 60 years, although the biological reasons for this remain unclear,” reports researcher David Lee. “The positive effects vitamin D appears to have on the brain need to be explored further but certainly raise questions about its potential benefit for minimizing aging-related declines in cognitive performance.”

    Although no one has pinpointed the optimal dose of vitamin D,iv taking supplements obviously seems to be a good preventive measure for keeping your brain healthy. Few other nutrients are as important for brain power.

    How Much D is Enough?

    You probably need far more vitamin D than you ever thought, and far more than even ardent alternative doctors are likely to recommend.

    For years, mainstream medical authorities stupidly and ignorantly told the public it was dangerous to take more than 400 IU a day. As recently as eight years ago the medical authorities were attacking doctors who suggested that far more vitamin D was needed and that supplements of 2000 IU per day were safe for most adults.

    As evidence has piled up, mainstream medicine has backed off and now acknowledges some of the amazing benefits of vitamin D, but they’re still far behind the best science on this subject. If you believe what your conventional, mainstream doctor tells you about vitamin D, you are putting your health at serious risk.

    Vitamin D is well tolerated at doses of up to 2,000 IU daily for adults. But the truth is, even 2000 is too timid and conservative. There is almost no danger of toxicity – and abundant evidence of huge benefits to your health – at much higher doses.

    Many studies suggest 35 IU’s per pound of body weight. That would put the daily requirement at more than 5,000 IU for a person who weighs 150 pounds. Sunshine on exposed skin is the best source, when weather and time of year permit.

    A blood test is the only way to ensure your vitamin D levels are adequate and to help you adjust your supplement intake to make sure you’re getting what you need. You may be in for a surprise. Despite taking 4,000 to 5,000 IU of vitamin D per day and getting quite a bit of sun as well, I recently found that my own blood levels were still too low according to a blood test.

    If You Get Yourself Tested,
    Here’s What the Numbers Mean

    The blood test measures your vitamin D levels in terms of nanograms of vitamin C per decliter of blood. You want your level to be above 60, and my research team has learned from interviews conducted with top doctors that, in fact, blood levels as high as 60 are rare.

    In other words, nearly everyone is deficient.
    If you’ve got a serious disease of aging like cancer or Alzheimer’s, levels of 80 to 100 are desirable. Such levels are nearly unheard of. In the blood test I mentioned earlier, I came in at 40 – and I had been supplementing with 4,000 – 5,000 IU of vitamin D per day! I then upped it to 12,000 per day, and I’m now reducing my intake, having reached a healthy blood level.

    What about toxicity? Excessive levels of vitamin D can lead to excessive levels of calcium in the blood, which can be toxic. I’m not aware of large studies on the subject, but one doctor told us that a D level of about 160 appeared to be the danger point. Readings that high are so rare, it’s unlikely a doctor who has tested hundreds of patients has ever seen a patient with a toxic vitamin D level.

    Muscle spasms are a symptom of the toxic condition, and if you suddenly start experiencing those after a long period supplementing with large amounts of vitamin D, it would be wise to cut back on the vitamin and get yourself tested again. The ideal way to supplement with vitamin D is under the guidance of an informed doctor who knows what he’s doing.

    When your hands get dirty, you wash them.

    And you might want to do the same with your brain.

    No, brain cells don’t acquire dust and grime, they accumulate cellular waste. And washing that out may protect you against memory problems like Alzheimer’s disease. Here’s what you need to do. . .

    Is this the end of Alzheimer’s?

    On December 13th of 2013 Oxford researchers stumbled onto a natural treatment for Alzheimer’s that patients are calling a “Godsend”.

    It slashes symptoms better than any drug on the market…

    And one lead researcher describes it as the first treatment that “actually works.”

    But in America almost no one is talking about it…

    Until now. One renowned doctor is releasing full details on this new game-changing Alzheimer’s treatment in this stunning free video.

    Watch now and learn how you can put it to work for you or a loved one with no prescription today!

     

    Disposal System

    The cells in the body continually take in oxygen and nutrients, create energy and produce metabolic refuse. But as you grow older, blood flow slows down, so the delivery of oxygen can become sluggish and the elimination of waste becomes inefficient.

    The good news: You can accelerate the removal of sludge from the brain. Researchi at the Texas Health Presbyterian Hospital’s Institute for Exercise and Environmental Medicine shows that it’s a fairly simple matter to improve the brain cleansing process and eliminate problematic proteins linked to Alzheimer’s.

     

    A Peek Inside the Head

    In the first phase of this research, the Texas scientists measured the blood flowing through the brains of 16 women who were over the age of 60 by means of a technique called Doppler ultrasonography. The imaging system allowed observations of how blood was behaving inside the women’s carotid arteries.

    Those arteries in the neck are the pathways through which blood, enriched with oxygen and glucose, travels to the brain. The researchers also analyzed the women’s maximal oxygen consumption — what is known as VO2 max. VO2 max represents the body’s maximal ability to convey and use oxygen during physical activity.

    Once that data was compiled, the scientists assigned the women an aerobic physical fitness program.

    The program started the women out exercising (briskly walking) at about 50 percent of their VO2 max for thirty minutes at a time, three times a week. Over a period of three months, the women gradually stepped up their walking until the sessions were 50 minutes each, four times a week, along with a pair of more strenuous weekly sessions at 70 to 80 percent of their VO2 max for thirty minutes at a time.

    Blood Measurements

    After ninety days, the researchers measured brain blood flow again. The flow through the carotid arteries had increased by 11 to 15 percent. The women’s VO2 max, on average, had increased by about 13 percent. In addition, their blood pressure dropped, on average, four percent and heart rates went down about five percent.

    According to researcher Rong Zhang, these improvements demonstrate how exercising to improve cardiovascular fitness can boost brain health: “There are many studies that suggest that exercise improves brain function in older adults, but we don’t know exactly why the brain improves. Our study indicates it might be tied to an improvement in the supply of blood flow to the brain.”

    Zhang adds that a reliable, copious flow of blood to the brain is important in two ways:

    • Increased blood supplies extra oxygen, glucose and crucial nutrients to the brain. Those improve brain health.
    • The expanded blood flow cleans out metabolic wastes including amyloid-beta protein which has been tied to the development of Alzheimer’s disease.

    Zhang notes that his research shows you can improve your brain blood flow even if you are over the age of 60: “We often start to see a decline in brain perfusion and cognitive function in the 60s and 70s. That’s when the downward trajectory starts. We want to see how much we can do to reverse or delay that process.”

    These studies show that by walking and exercising today, you can enjoy a cleaner brain and a more lucid memory tomorrow.
