Only water today, folks. No soda, soft drinks, spritzers, vino, pop, energy drinks or triple-shot sugarfests. Water really is the best liquid you can give your body – although, having said that, I don’t buy the 8-glasses-a-day line. Drink when you’re thirsty. If you’ve already had your coffee, well, nobody’s perfect. Now, can anyone do all water, all week?
Report back, Apples.
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 lead us to believe we could stay out even longer. Little did we know that the burning of skin might have been a great first warning to get the hell out of the sun! How’s that for nature’s way of saying “Yo! Enough!”? Unfortunately, the sunscreen gave us the false notion we were invulnerable. Oops. Guess big Pharma was wrong again. More on that later….
EVERYTHING YOU EVER WANTED TO KNOW ABOUT:
WHAT IT IS: Grapeseed extract is derived from grape seeds. Usually, red grapes make the best source. However, it’s a little more complicated than that. Like green tea, bark and some fruits, grapeseed extract contains particular antioxidant compounds called polyphenols. But some grapeseed extracts vary in the type of polyphenols they contain. There are a handful of different types, depending upon the length of the “chain” in the extract. They range from short monomers to long cyanidins, which is the scientific name for those headache-inducing tannins. The longer the chain, the less beneficial. The best grapeseed extract contains chains of 2-7, usually called oligomers.
The typical grapeseed extract supplement won’t mention any “mer” at all, and it’s hard to ensure that the product is actually beneficial.
STUDIES SHOW: Studies show that grapeseed extract has excellent antioxidant abilities similar to green tea and vegetables. It’s one of the most potent antioxidant sources in the world, containing even more than the famously hyped pycnogenol. Grapeseed extract contains polyphenols, also called flavonoids or catechins. These compounds strengthen the arteries, improve free radical destruction and even help to prevent macular degeneration and cataracts. Studies have also shown the important cancer-fighting potential of grapeseed extract, as well as the tremendous potential benefit to the heart. And recent studies have established that the extract can help to reduce inflammation.
WHY WE LIKE IT: Grapeseed extract fights free radicals and oxidative stress. This means that grapeseed extract can also be of great potential benefit for fighting or preventing cancer, heart disease, and effects of aging. Studies done on grapeseed extract give scientists a clue as to why moderate wine intake may be beneficial for the heart. Known as the “French paradox,” scientists have been puzzled for years as to why the French, who consume large amounts of fat, have low rates of heart trouble. Scientists know explain it has something to do with the antioxidant, cardio-protective properties contained in grapeseeds. Grapeseed extract contains all the benefits of antioxidants without the toxic effect of too much alcohol.
Last week we brought you a great new way to track your dieting progress with The Daily Plate. But The Daily Plate isn’t the only ‘Web 2.0’ application in the online universe that is designed to help you cut the fat. Introducing Traineo. The philosophy behind Traineo is that having a coach, friend, or spouse to motivate you through your journey of weight loss is the best way to see results. Having a personal motivator talk you down from that box of doughnuts you were about to consume can pay huge diet dividends.

While you can’t pick and choose your food items from a database of thousands of dishes there are many other features that set this website apart. Beside the ‘motivator’ feature, there are online forums, featured articles on health and nutrition, and a ‘My Stats’ page that allows you to track you weight loss over time. The greatest part of this incredible resource is that it is entirely free. If you are looking for yet another tool to help realize your health goals and would like to unite with similarly minded people this may be just the ticket.
