1. Do multivitamins really work?

    Don't throw out your vitamins yet

    Take your vitamins, and toss 'em right out the window -- because they're a waste of time and money, according to an angry new editorial in the Annals of Internal Medicine.

    The editorial even declares the "case is closed." That's how science works, right? You make a big, bold statement, and then declare it's no longer open for debate.


    One of the authors of the editorial has had it out for vitamins for years, but he's a guy who barely does a lick of the actual science himself. No, his game is to cherry-pick other studies that agree with his agenda.

    That's not science. That's a vendetta.

    So here he is, cherry-picking away -- yammering on, for example, about a recent study that supposedly proves multivitamins won't prevent cognitive decline.

    Now, I'll leave aside the fact that the study found little real cognitive decline in anyone, whether they were on a placebo or vitamin. You can't really claim vitamins failed to prevent a disease if it never showed up in the first place.

    No, the real issue is that multivitamins aren't magic brain pills -- and no one ever claimed they were.

    Multivitamins are there to cover you on the basics by supporting your overall health and immune system. But when you're facing serious disease, you need to break out some bigger guns.

    In this case, high-dose B vitamins have proven to slow, stop and even reverse the signs of cognitive decline -- and they do it so well that B vitamins are being rushed to market right now as the next great dementia "drug."

    Another cherry-picked study claims vitamins won't stop future heart problems in heart attack patients.

    Again, I'll leave aside the big, glaring flaw: More than half the patients in the study stopped taking their vitamins, so you'd have to be brain dead to make any grand statements based on that ("Case is closed" comes to mind here).

    No, the real issue is that a heart attack goes beyond the scope of a multi the way a nine-inch gash goes beyond the reach of a Band-Aid. When you've had a heart attack, you need more -- you need a few nutrients you won't find in a typical multi, such as coenzyme Q10 and magnesium.

    Oh, and unlike the author of the editorial I can provide you a STACK of studies to back up those claims.

    So don't toss your multivitamin just yet. Just remember it's not a magic cure all pill but rather a starting point -- not the "case is closed" final word on your nutrition.

  2. Selenium can fight aggressive prostate tumors

    Slash your risk of prostate cancer with this mineral

    OK, you're smart enough to know the score on prostate cancer by now.

    The key to beating this disease isn't in PSA tests. It's not in spotting or detecting every little tumor that comes your way, because most of them are 100 percent harmless.

    And it's certainly not in the drugs and surgeries that can leave you with a leaky, limp and dysfunctional penis for the rest of your life.

    No, the REAL key to prostate protection is in avoiding the rare and aggressive cancers that really can kill you -- and there's one simple and delicious step you can take right now to slash your risk of those tumors: Eat a handful of Brazil nuts.

    Brazil nuts are the absolute best source of the cancer-fighting trace mineral selenium, and one new study confirms it can slash your risk of Stage III and Stage IV prostate cancers by 63 percent.

    I can think of only two problems with selenium. The first is getting it, since -- besides those Brazil nuts -- the sources of selenium are wildly inconsistent and vary based on the mineral content in the soil where your food is grown.

    A good source of selenium in one region can be a lousy source in another.

    The second is getting the RIGHT amount, because this is a case where you can get too much of a good thing -- and Brazil nuts have such high levels of selenium that eating too much of them too often can actually be bad for you.

    Stick to a handful of nuts two or three times a week. Or better yet, get your selenium from your multivitamin.

    Look for one that contains roughly 200 mcg. That's almost triple the "official" recommended intake, but it's roughly in line with what you need for cancer protection, and not just from prostate cancer. Selenium can also slash your risk of cancers of the lung, colon, rectum, and pancreas.

    It's also pretty good at heart protection -- especially when taken with coenzyme Q10. For more on the hows and whys of that one, be sure to read this free report from my archives.

  3. Selenium, tea can cut diabetes risk

    Selenium and tea can cut your diabetes risk. But if you're obese and not planning to make any other changes, don't even waste your time with selenium and tea.
  4. Coenzyme Q10 and selenium can slash heart risk

    Two key nutrients you should be getting anyway -- coenzyme Q10 and selenium -- have been shown to cut your risk of death by heart disease in half.
  5. Can veganism cause pancreatic cancer?

    Pancreatic cancer is the disease that ultimately claimed the life of Steve Jobs last year -- and if a guy with all that power and money can't beat it, you know it's bad news. But I can't help but wonder if the guy's vegan lifestyle did him in -- because there's a key mineral that can minimize your risk of this deadly cancer... and if you're munching on bunny chow, you're missing out.
