Today's Post: Tuesday, 10-19-2010
Recently from late last week to yesterday I ran across reminders that October is breast cancer awareness month.
There ARE ways that effectively help prevent cancers. Some of them have also been separately found to prevent breast, prostate, and ovarian cancer.
But I’ve posted on them before and was reluctant to just do another for breast cancer awareness month when I had no new information. That changed earlier this morning.
1. This morning, Dr Al Sears sent an email that gave me some essential new information to add.
For some while, he has been writing about how the telomeres, or DNA protecting ends -- inside our cells that act something like plastic shoe lace caps -- are related to aging. When they are long enough, the DNA makes perfect copies. But when the telomeres shorten too much and unravel enough you get either imperfect copies or even none at all. This is almost certainly the underlying cause of aging.
The good news is that we now know some things that help your telomeres stay long and some that shorten them. Like so many aspects of protecting your health, if you do the protective things and mostly avoid the harmful things, you can get some real leverage on protecting your health. And, in this case you also slow aging or even reverse it slightly.
But this morning, Dr Sears, came in with a blockbuster!
He found several studies showing that short telomeres tend to increase cancers and long telomeres tend to prevent cancers. (Apparently some of the imperfect DNA copies with short telomeres become cancers.)
That means three things. In addition to the list of things that are known separately to prevent cancer, we now may know why some of those things work to prevent cancers AND we now know a very powerful set of MORE things to do that both slow aging AND prevent cancers.
Here are some quotes from his email today.
“A new study published in the Journal of the American Medical Association found that longer telomeres can dramatically reduce your risk of cancer.”
“A Virginia study found that breast cancer cells had shorter telomeres than normal cells.”
“A research team at Harvard discovered that having short telomeres nearly doubled the risk for bladder cancer.”
“According to Japanese researchers, cancers of the mouth begin in cells with short telomeres.”
A”….new Italian study….measured overall cancer risk. These doctors found that people with the longest telomeres were the least likely to develop cancer. In fact, they were more than 10 times less likely to develop cancer than people with short telomeres.
And people with short telomeres are twice as likely to die from cancer.”
This clearly means that you can cut your risk of all cancers rather dramatically by doing what you can to keep your telomeres longer.
Here are some of the methods to keep your telomeres long and prevent them from being shortened that Dr Sears listed.:
“Exercise is one of the best ways to slow the aging of your cells to a crawl and reduce your risk of cancer. One reason was discovered by researchers in Germany. They found that intensive exercise keeps your cardiovascular system from aging by preventing shortening of telomeres.
Another comes from a study done at the University of California in San Francisco. It found that vigorous exertion protects you from high stress by protecting your telomeres.”
We’ve already posted on separate studies showing that regular vigorous exercise slows aging substantially, cuts the death rate from all causes other than accidents etc, and dramatically improves biomarkers of heart health. These two studies now show why this is so. Exercise both keeps your telomeres long directly and keeps stress from shortening them! These findings also helps explain why exercisers get fewer cancers and women who exercise get fewer breast cancers.
“ Cold-water, high-fat fish like mackerel, wild salmon, lake trout and herring are good sources of omega-3, which can lengthen your telomeres.”
“Besides exercise and eating the right foods, did you know that supplements also offer protection for your telomeres?
For example, according to the National Institutes of Health, women who simply take a multivitamin have 5 percent longer telomeres than those who don’t.
And….vitamins C and E and resveratrol – also appear to slow the shortening of telomeres.”
“One vitamin is actually linked with lengthening your telomeres, and you don’t even need a pill to get it. It’s vitamin D.15 Just 10 minutes in the sun gets you 10,000 units.”
You can also take 2,000 to 10,000 iu a day of vitamin D3. And, the very large number of health benefits found from doing so include preventing many cancers.
Dr Sears also wrote that : “Obesity and smoking will shorten your telomeres.”
Many smokers don’t yet know that smoking causes something like 30% of all cancers – not just lung cancer --- and has been shown to speed up aging. Now we know one of the several reasons why this is so. (Not smoking and avoiding virtually all second hand smoke is a key way to prevent all cancers that we have already posted about.)
Obesity also has been found more often in people who get cancer and breast cancer. We just saw that the kind of regular and vigorous exercise obese people tend NOT to get prevents cancer.
And, obese people tend to NOT eat the nonstarchy vegetables and fresh fruit that contain the natural forms of many of the vitamins that keep your telomeres long.
2. In the book Anti Cancer, that we’ve reviewed before, the author shows that in addition to getting enough omega 3 oils, NOT ingesting the massive overdose of omega 6 oils that most people get is a critical way to prevent inflammation. The studies he found showed that such inflammation not only causes heart disease, it also sharply increases the rate of most cancers.
Foods to avoid that do this include refined grain foods, whole grain foods in more than moderate amounts, virtually all the oils high in omega 6 including corn, soy, safflower, and canola. And, it includes the fats from animals fed grain instead of their natural foods. To avoid those, eat meats and poultry that are only grass fed or pasture fed, eat far less grain fed meat and poultry and when you do, remove as close to all the fat as you can manage. Similarly, use nonfat and very lowfat dairy and limit cheese unless it comes from cows fed only grass.
Most of the commercial treats and snacks obese people eat are loaded with these sources of omega 6 oils. So eating none of these or WAY, WAY less of them not only can help people stop being obese, it’s a key way to prevent cancers.
3. A truly impressive list of plant foods also have dramatically effective preventive powers in preventing cancers and in preventing the aggressive and deadly form of cancers.
Many of the cruciferous vegetables only do this well in their raw state. Broccoli and cauliflower are two of these.
The Anti Cancer book also rates Brussels sprouts, onions, and garlic as very powerful cancer preventers.
The carotene lycopene in tomatoes also helps prevent cancer. But oddly enough, it is something like ten times as bioavailable when you eat tomatoes that have been cooked and/or pureed with extra virgin olive oil.
Blueberries and other berries also have cancer-preventing effects as do most citrus fruits.
4. Lastly, two other supplements also help prevent cancers besides the vitamins and resveratrol that seem to help keep your telomeres long.
a) CoQ10, particularly the much more bioavailable form of it, ubiquinol, very likely also helps keep your telomeres long. But taking it also seems to prevent cancers from developing new blood supplies while at the same time NOT preventing normal cells from doing so.
It also helps you protect your heart and keep your natural energy as you get older.
b) Curcumin or the Turmeric spice that contains it apparently works with vitamin D3 to help prevent both Alzheimer’s disease AND most cancers. So taking that daily or eating curried foods that contain turmeric several times a week or both looks to be unusually protective.
In addition, consuming it with black pepper has been reported to make the cancer preventing effects as much as 200 times stronger. The theory is that this combination makes the curcumin more bioavailable to your body.
The bad news is when you add all the parts of the things you can do to prevent cancer, the list is truly imposing.
But, the good news is three-fold.
You may well already be doing many of them.
Virtually all of them have multiple health benefits in addition to preventing cancers.
And, you can start with just adding one new thing from this list. You do NOT have to do it all in one pass!
