1. Signs of high blood sugar harm memory

    Signs of High blood sugar harms memory

    If you don't have diabetes, it's pretty easy to ignore your blood sugar levels. After all, even without diabetes, you've probably got enough other health concerns to worry about, right?

    Well, ignore those numbers at your own risk -- because signs of high blood sugar can damage your brain, harm your memory and set you up for dementia, and not just in the long term.

    It could be hurting you right now, as new research finds older adults with even slightly elevated blood sugar levels do far worse on memory tests than older adults with normal blood sugar levels.

    The study even shows why: As your blood sugar levels rise, even just a little nit, your hippocampus can shrink -- and that's the part of the brain you need for memory and learning.

    What's most alarming of all is that none of the 141 older adults in the study were diabetic. They weren't even pre-diabetic. They weren't heavy drinkers, they weren't overweight and they weren't suffering from any overt signs of memory loss or cognitive decline.

    They were, by most mainstream measures, healthy -- with some of them at the high end of the "normal" range, or just beyond it, for blood sugar.

    Clearly, it's time to stop considering those levels to be normal or healthy, and this study isn't the only reason why. Other studies have also shown how even slight bumps or signs of  high blood sugar can set you up for memory loss and dementia.

    And a growing body of evidence shows that blood sugar plays a central role in your overall health and longevity -- and signs of high blood sugar can cause serious damage even at levels not high enough to be considered diabetes or pre-diabetes.

    Mainstream guidelines say to keep your total blood sugar below 100, but my guidelines are a little stricter. Aim for 90 or less.

  2. Sleep can be natural detox for the brain

    The natural detox you can try tonight

    Not long ago, detoxification was dismissed as "alt-med mumbo-jumbo." Today, the mainstream is finally starting to recognize the role of toxins in disease -- especially in diseases of the brain.

    I think it's only a matter of time before you see mainstream doctors offering the same natural detox programs I do for brain protection.

    For now, however, you'll have to visit a holistic physician for most natural detox treatments. But there's one you can get started on tonight, in your own home, and it won't cost you a penny.

    All you have to do is fluff your pillow, lay back and get some rest -- because new research confirms that a full night of sleep is one of the best ways to rid your brain of the toxic junk that can cause memory loss, cognitive decline and dementia.

    When you sleep, your brain cells shrink by 60 percent, according to the study -- but it's not the type of shrink you need to worry about.

    They shrink so the toxins that accumulate in the brain -- including the beta-amyloid responsible for dementia -- can slide out in the space that opens up between cells.

    Then, when you wake up, your cells return to their normal size.

    Of course, the flipside to this is what happens when you don't get enough sleep: you interrupt your natural detox process, allowing toxins such as beta-amyloid to accumulate and cause damage.

    It helps explain why poor sleep is linked to cognitive problems, and consistently poor sleep is known to increase the risk of dementia.

    The one downside to the study is that it was on mice, not humans. But we've seen similar studies on other animals, including dogs and baboons, so it seems quite likely that all of our brains have this same built-in cleanup program.

    In other words, make sure you get a full night of sleep -- tonight and every night.

    I wish I could say that's all you need to do to rid your brain of toxins. Unfortunately, modern life has exposed us to more toxins than our brains were designed to handle -- including damaging metals such as aluminum, copper, iron and more.

    Sleep alone can't clear all that out -- for that, you need to work with a holistic doctor who can identify the toxins you've been exposed to and work to rid your body of them naturally.

    If you're in Southern California, I can get you started here in my clinic. Contact my office for more information or to make an appointment.

    And if you're not in the area, I can help talk you through the process over the phone and create a detox diet custom tailored to meet your needs. Call 855-DOC-MARK to learn more, or schedule a call.
