1. How fish oil can stop oxidative stress

    Omega-3 protects the brain

    Aging gets a lot of bad press, but the real reason seniors have a higher disease risk isn't time alone.

    It's the oxidative stress that comes along with it.

    That's why it's so important to make sure you're getting sufficient levels of antioxidant nutrients as you get older. But don't stop there -- because while the omega-3 fatty acids found in fish oil generally aren't considered antioxidants, they can also help prevent or even reverse the damage caused by oxidative stress.

    And that's especially true in the brain.

    In one new study, seniors with the highest intakes of DHA and EPA had the lowest levels of lipid hydroperoxide, or LPO.

    OK, there's a lot of letters in that alphabet soup, so let me sort them out for you.

    DHA and EPA are, of course, two of the most essential omega-3s -- and the two main fatty acids you'll find in a quality fish oil supplement.

    LPO is less familiar to most people, but it's a common marker of oxidative stress in the brain. You want as little as possible, and the new study shows why: It increases the risk of cognitive impairment -- specifically, problems with global cognitive function, short-term memory, learning, and attention.

    High levels of omega-3s, on the other hand, can do just the opposite, protecting overall cognitive function as well as short-term memory, attention spans, and recall, according to the study in the Journal of Nutritional Biochemistry.

    The researchers believe DHA in particular helps the body to produce the enzymes needed to fight oxidative stress damage in the brain.

    And that may be part of it.

    But we also know from other studies that omega-3 fatty acids protect the brain in a number of other ways, both directly and indirectly. Indirectly, they help with heart health and overall circulation -- and good circulation is critical to brain function.

    More directly, the brain itself thrives on omega-3 fatty acids -- which is why fish oil has been shown to help protect and improve memory, mood, and more even in healthy people.

    Be sure to look for a quality supplement that has been purified to remove contaminants such as mercury.

  2. 1 in 8 seniors fighting memory problems

    Fight memory loss and brain fog

    Seniors like to say "life begins at 60" and for good reason: Your golden years can be among the best years of your life.

    But for millions of older people, something else begins at 60 -- memory problems that can threaten to turn your best years into some of the worst.

    New government numbers show 1 in 8 Americans over the age of 60 are battling "brain fog," memory loss, or other signs of cognitive decline. And for a full third of them, the memory problems are so bad that they interfere with or limit daily function.

    Now, some people will tell you memory loss just means you're getting older... that it comes with the turf... and there's nothing you can do about it.

    But I know that's not true.

    In many cases, memory loss and other cognitive problems accompany aging, but they're not necessarily caused by aging. Just look at the over-60 crowd in the new study: Sure, they're getting older.

    But folks over 60 are also among the nation's leading consumers of prescription medications -- and many of those medications come with a notoriously high risk of memory loss and other cognitive problems.

    Blood pressure drugs, for example, can lead to memory loss. And cholesterol-lowering statin drugs are so notorious for this risk that the FDA recently issued a warning over it. Painkillers, antidepressants, and more can also do the job -- which is why whenever patients complain of memory loss, the first thing I do is look at any drugs they've been given by a mainstream doctor.

    (If you or a loved one has been diagnosed with dementia or even Alzheimer's disease, you need to know that the real source of the problem might be in your medicine chest. Click here to learn more.)

    In some cases, the drugs were never even necessary in the first place. In many others, they can be replaced by natural alternatives that can work just as well, but without the side effects.

    Of course, not all memory problems are due to meds. But that doesn't mean the rest are due to aging, either.

    Diabetes, for example, is known to increase the risk of dementia -- and another new study shows how elevated blood sugar levels can increase your own risk even if you don't actually have diabetes.

    In the study, brain scans of 124 patients who were healthy but had a family history of Alzheimer's revealed reduced metabolism in key regions of the brain among people with elevated blood sugar levels.

    Those are the same changes we see in Alzheimer's disease.

    What makes this truly frightening is that the "high" blood-sugar levels in the study aren't sky-high. They're at the high end of the normal range, or levels that millions of otherwise healthy Americans seniors live with every day.

    Other conditions that can cause, mimic or worsen memory loss and dementia include exposure to toxic metals such as lead, which is why I also frequently test for metals.

    You might be surprised to find out how much metal you have inside yourself right now -- and even more surprised at how much better you feel after detoxification.

    If you're suffering from a little "brain fog" yourself, don't ignore the warning signs. Work with a holistic doctor to find the cause -- whether it's medication, blood sugar, metals, nutrition, hormones, or something else entirely.
