1. High protein foods can boost cancer risk

    Our is diet killing you

    That cheeseburger may be the death of you -- and I'm not kidding.

    Too much meat, cheese and other unhealthy high protein foods in middle age can quadruple your risk of death from cancer, according to a major new study.

    That makes a Dairy Queen habit as bad for your health as smoking, and the risks don't end with cancer.

    If you get 20 percent of your diet from animal protein and high protein foods, you could also face four times the risk of death from diabetes and double the risk of an early death from any cause, according to the new study in Cell Metabolism.

    Cutting protein in your diet down to 10 percent or less, on the other hand, will cut your risk death from any cause in half and death from cancer by 25 percent.

    Surprised? Don't be.

    Part of the reason is likely in your hormones, specifically a hormone known as insulin growth factor-1, or IGF-1.

    When you're young and growing, you need plenty of it. But as you get older, you need less. In fact, as you get older, too much IGF-1 can hurt you.

    This shouldn't be a problem because of the ingenious way in which we've been designed: Your body naturally produces plenty of IGF-1 when you are young and need the stuff, and much less as you age.

    But bad habits can disrupt this natural process, especially the bad habits of the modern junk-food diet, which can cause your IGF-1 factory to start pumping out hormones overtime just when production should be tailing off.

    Of course, that's one reason -- but I don't believe it's the only reason.

    Not all high protein foods are unhealthy, but people who eat the most animal proteins tend to be people who aren't making healthy choices. They're eating cheeseburgers and drinking milkshakes.

    Eat quality proteins such as fish, lean meats and poultry, and I'm sure crossing the 10 percent threshold won't hurt you.

    If there's one upside to the study, it's that it also finds that higher levels of protein can actually help extend lives in seniors.

    This may be in part because seniors are so low in IGF-1 that even a bump in production from protein won't hurt. And it may also be because seniors tend to lose muscle mass as they age and a diet too low in protein can accelerate that process.

    Loss of muscle leads to weakness, loss of balance, falls, breaks, loss of independence and a higher risk of an early death.

    Healthy proteins (and amino acids) can support your muscle so you stay strong.

    In other words, don't celebrate your 65th birthday under the Golden Arches. Instead, continue to make sure your proteins are quality proteins, and limit your red meat intake.

    For a balanced diet with just the right amount of healthy proteins at every age, I recommend a Mediterranean lifestyle rich in lean meats, fatty fish, olive oil, nuts, seeds and all the fresh produce you care to enjoy.

    This diet has been proven to cut the risk of cancer and diabetes. (Yes, precisely the diseases that a diet too high in protein can cause.)

  2. Testosterone levels in men can ease MS

    Hormonal help for men with MS

    Multiple sclerosis is misery on a grand scale, affecting everything from how you walk and move to how you think. But there's one weapon men can use to fight back -- a substance so natural, it's already in your body right now.

    It's your hormones.

    Specifically, the testosterone levels in men-- and new research on 100 men with this disease confirms that higher levels of "manly" hormones can lower your risk of some of the disease's worst symptoms.

    The most important one is disability. If you're fighting MS yourself, you probably know all too well how the disease can not only keep you from work, it can also keep you from doing all the things you love.

    But as the new study shows, higher testosterone levels in men could  mean a lower risk of overall disability.

    So far so good, and the benefits aren't just physical. They're also mental, high testosterone levels in men mean a lower risk of declines in cognitive function over two years.

    It's not just testosterone, and it's not just men. It's not even limited to MS -- because hormones often play a key role in all the major autoimmune diseases.

    But let's stick to MS today. Along with testosterone, the disease can be triggered or worsened by low levels of thyroid, IGF-1, estrogen, and the stress hormones cortisol and DHEA.

    In some cases, supplements can increase your levels of these hormones, but don't take this on as a "do-it-yourself" project. You need to work with a holistic doctor who can test your hormone levels and determine which ones you may need and the best ways to increase those levels.

    Also, while hormones are often a piece of the MS puzzle, they're often just that: a piece. In some cases, they play a major role. In others, they can play little to no role at all.

    Other suspects in MS include exposure to metals, other toxins as well as chronic infection, stress, and vitamin D deficiency. But I've found that some of the biggest triggers of autoimmune diseases in general and MS in particular are on your plate and in your lunchbox.

    They're food allergies, especially sensitivities to the chemicals and preservatives used in processed foods. Eliminate them and stick to a diet of natural whole foods, and your symptoms will likely ease.

    The same holistic doctor who can work with you on those hormone tests I mentioned earlier can also test you for food sensitivities and help develop a diet that will put your disease into remission and keep it there.

    I'm proud to say I've helped plenty of MS patients here in my clinic. If you're in Southern California, I can help you, too. Contact my office for an appointment.
