A doctor weighs in on the HRT-cancer connection. The controversy isn’t going anywhere, anytime soon.
I recommend reading the whole interview if this is an area of interest for you. What caught my attention is the subtle pro-drug stance the interview appears to take, while simultaneously bringing out revealing facts like the following:
Q. Was it a surprise to learn that estrogen and progestins can cause breast cancer?
A. We’ve known there is a cause and effect with hormones and breast cancer since 1896.Read More

We love how the posts over at Ririan make life so much easier and more productive. Check out the essential tips for good sleep – and we’ll add one to the list…
Spend 5 or 10 minutes before bed doing one of the following:
– Journaling (write your thoughts, your to-do list, your worries, whatever!)
– Prayer or meditation (concentrate on the positive – focus on appreciation)
– Light a candle, take 10 deep breaths, and decide to get a great night’s sleep. You’ll be amazed at how the decision to rack out will really work! (Work up to 20, 30 or more deep breaths before going to sleep.)
2. Allergic? Pour It On
We’ve been noticing a particular allergy hypothesis begining to take hold in the scientific community. Well, actually, Mark has been noticing and pointed it out. Scientists are finding that, in some cases, increased exposure to an allergen seems to be the best way to cure the allergy. Of course, this is not a “do it yourself” experiment; so far, studies have been strictly controlled in labs. The latest study could make a big difference for children’s food allergies. Check it out by jumpin’ on this clickativity.

Made you think twice, didn’t it?
Many of us glom on the sunscreen in the hope of warding off the slightest wrinkle or, worse, skin cancer. And many of us diligently gulp down glass after glass of milk, convinced calcium will save our bones from the high rates of osteoporosis Westerners suffer from.
Enter critical reassessment.
For those craving some clickativity related to Mark’s examination of the Vitamin D-sunblock-health issue, the New York Post ran a terrific piece recently on the importance of getting your daily D-licious dose. I tend to beat the osteoporosis horse quite a bit – but hey, it’s important! D is absorbed through the skin. D is necessary for bones. And sunscreen stops this nice little evolutionary convenience from…well, convening.
As Mark points out, why slather on a sunblock that doesn’t prevent the more dangerous UVA rays (thanks, Uncle Sam), does prevent absorption of critical vitamin D that is as equally important to bone health as calcium, and interferes with nature’s built-in “Get your buns indoors!” mechanism? (Or, as the Big Apple puts it, burning to a crisp.)

Let me be the first to say: I am pro-sunlight. I’m not talking about weather patterns, either. I’m talking about exposing yourself to some rays. I spend a fair amount of time outside soaking up the sun’s energy (of course, being careful not to burn). Although evidently most dermatologists believe we would be better off spelunking in caves 24/7 and covering ourselves in head-to-toe black garb whenever we venture out, my own evolutionary perspective leads me to believe we were designed to get sunlight almost every day and that our health suffers if we don’t get enough. In fact, recent studies show that, as a result of our shunning the sun, many of us suffer from Vitamin D deficiency and a resulting loss of bone density and immune function (to name just a few effects). Some researchers opine that more people die from lack of sun than from too much sun! But, I digress. I came across an article the other day that piqued my curiosity since it dealt with the combination of running and sunning. It basically showed that marathoners (e.g. formerly yours truly) tend to get skin cancer at higher rates than other people. The more they run, the higher the incidence of skin cancer. My take on what’s happening is that not only are runners exposed to more sun (which can cause DNA damage in skin cells – ergo, cancer), but they are also bathed in more free-radicals overall from the excessive oxidation of glucose and fats. We know that sun exposure does deplete the skin of the antioxidant Vitamin C. Stick with me on this: the act of running tends to divert blood flow away from the skin, starving it of additional important antioxidants that could neutralize the free-radical damage in the skin tissues. Add to that the enormous amounts of stressful cortisol marathoners pump out doing this unnaturally high steady-state oxidative work and we not only get the DNA damage, we get the immune-bashing effects of the high-stress activity. The effect: more DNA damage and a reduced ability to recognize that damage and take steps to eliminate those cells and/or repair the damage. That’s one reason (among many) that I have doused myself with antioxidants inside and out for over 20 years now. That’s also why one of my mantras is: a little running is OK – a lot is bad. The above article also brings up other points of discussion, such as whether the reliance on inferior sunscreens might be another cause. This is vitally important to discuss and it’s not getting much attention in the mainstream media. It appears that for the past 30 years so-called sunscreens have been good at blocking UVB rays (the ones that burn) but not UVA (the ones primarily responsible for DNA damage and skin cancer). Thank you, FDA. The terrible effect is a generation of gung-ho health fanatics slathering on sunscreen and running 40, 50 or 100 miles a week. The fact that we didn’t burn only … Continue reading “Sunscreen May Not Be Your Friend”Read More
I can’t tell you how furious I am about what I feel is the meat industry’s blatant disregard for human health. While I’m no vegetarian, I saw this study in the Archives of Internal Medicine, and let’s just say, I’m not buying the “Happy Cows” line.
The researchers looked at 90,000 women. That’s a huge study. They compared US and UK women, and here’s what they found:
Eating more than 1.5 servings of meat daily doubles a young woman’s risk of breast cancer. What concerns me is the type of cancer which had double the risk: hormone receptor-positive breast cancer. To me, that says something pretty sobering about the meat industry’s production habits.
Both the study, and the BBC News article that covered it, are cautious to merely “suggest” a link between eating red meat and increasing – doubling – the risk of breast cancer. It doesn’t take much to read between the lines here.
The reason I think this study is really important to highlight is not because I hope to bandy a statistic like “double the risk!” about. (Remember the Statistics Game: always consider context and relative risk or results.) It’s important because the women who ate high amounts of red meat had double the risk of hormone receptor-positive breast cancer. That is a big issue, namely, because the American meat industry uses growth hormone like it’s manna from Heaven. Growth hormone helps the animals get bigger, faster, which translates more profit – but I’m pretty skeptical about how this practice could possibly be in the interest of public health. I just wonder how these people sleep at night knowing their profits come at the expense of other human beings.
Personally, I believe it’s clear that human physiology supports being omnivorous. No culture anywhere at any time has done without some sort of animal flesh, whether it’s fish, beef or reindeer. So I’m not “anti-meat”. However, I am strongly opposed to the way meat is produced in this country: quickly, unethically, with little regard for the animals or the people eating the animals. That’s why I only buy meat that is free-range, local, organic and definitely hormone-free.
The researchers were careful not to draw any ultimate conclusions. I think we can probably begin to draw our own, with some additional critical considerations:
1) Processed meats generally contain a chemical known as heterocyclic acid, which has been shown to cause cancer;
2) Red meat, of course, contains iron, which can sometimes encourage the growth of some types of tumors (though this isn’t a significant concern, likely);
3) The standard line: “The biggest risk factors for breast cancer remain gender and increasing age.” This from specialist Maria Leadbeater, quoted in the BBC article. Fair enough.
