Flat Feet and Arch Supports

Maybe you visited your doctor after taking up running, and the doctor told you that your feet hurt because your arches fell. In other words, you have flat feet. Well the chances are that it’s your shoes, not your flat arches, that are causing the pain. The arch supports hurt your feet: You do not want humongous arch supports. You want shoes that are built with very mild (low) arch supports.

Both New Balance and Vasque make athletic shoes that fit flat feet and wide feet. Vasque even says that their Perpetuum last is “comfortable for people with flatter feet.”

So don’t quit running, walking, and hiking. Just buy the right shoes!

They Say Vegetables Don’t Stop Cancer. I Don’t Believe It.

This week the media told us all that a new study shows that eating lots of vegetables does not “significantly” lower cancer risk. (The study indicates that vegetables might provide a very small reduction in cancer risk, but that statistic may have resulted from reporting error and bias — see Eating Vegetables Doesn’t Stop Cancer: http://well.blogs.nytimes.com/2010/04/08/eating-vegetables-doesnt-stop-cancer/.)

The cancer researchers had 142,605 men and 335,873 women report on their eating habits and lifestyles during 1992 to 2000. They then assessed the association between cancer risk and diets high in fruits and vegetables.

But it looks to me that investigating the question “Does eating five or more fruits and vegetables stop cancer?” is like asking “Does taking five or more prescription pills stop cancer?” Obviously, I would not eat a random assortment of pills as a cancer-prevention strategy (nor would I take the over-the-counter pills that happen to be on sale each week).

I drink green tea and eat lots of garlic, tomatoes, apples, berries, greens, and cruciferous vegetables (cabbage, broccoli, cauliflower, and Broccolive). Then I include a very large variety of different fruits and vegetables in my diet, and to that end I also take powered fruits and vegetables and extracts (but I don’t take just one product day after day, month after month, year after year; I rotate them): Rainbow Vibrance Super Food, Progressive Nutritional PhytoBerry, and Drinkables Liquid Fruits and Vegetables Dietary Supplement, for example.

Research on the cancer-prevention properties of fruits and vegetables continues: On January 11, 2010, Texas AgriLife Research food scientists reported that mango prevents or stops colon and breast cancer cells in the laboratory. And at least one researcher at the Arizona Cancer Center in Tucson says a “vegetable-rich diet may avert some cancers,” especially a diet full of cruciferous vegetables: cauliflower, cabbage, kohlrabi, radishes, broccoli, and Brussels sprouts.

Beware of Advice from Meetup.com Members

If you join a Meetup.com activity, let’s say a hiking group, and you hear the members giving out impromptu advice regarding survival, health, injury, etc., make sure you consult a professional, too, or at least do some reading.

You might find that at a monthly hikers’ meeting, an attractive know-it-all is showing you a stretching exercise for your sore knee. But if you go to a good physiotherapist, you might learn that the stretching will only exacerbate your knee or hip injury, that what you really need to do is build muscle strength in the injured area.

Similarly, someone might tell you that no one dies from rattlesnake bites and that the Mojave Rattler is no more dangerous than a Diamondback. However, if you take the time to read page 583 in A Natural History of the Sonoran Desert (Arizona-Sonora Desert Museum) you will find that world-renowned experts write, “The Mojave has a very toxic venom that has caused human fatalities.”

Here’s couple of good (but brief) desert survival books:

Desert Cotton

In a previous post I talked about wearing cotton in hot deserts (see Cotton for the Grand Canyon). Now I would like to point out that in the Arizona desert beginning in September, you should carry a survival blanket and a lightweight polyester fleece shirt or jacket (and maybe even some silk-weight long underwear) if you expect the nights to be cool or if you are hiking to higher elevations. Then if you are unexpectedly delayed or caught out after dark, you can switch out of your cotton shirt and/or wrap yourself in the emergency blanket. Or you might want to dispense with the cotton and wear nylon shorts or pants and a short-sleeve polyester shirt, but when you expect the nights to be cool always carry an emergency blanket and an extra layer of clothing.

In the Phoenix, Arizona, area the nights can cool down substantially even in May, especially out in the desert, away from the city asphalt and hot cement.

Increased My Vitamin D to 2000 IU Per Day

I recently read a reputable article that said that we should be taking 1500 to 2300 IU of Vitamin D each day. I think I read the article on a life extension web site: http://www.lef.org/news/.

Mayo Clinic says that the upper limit for vitamin D is 2000 IU per day. See http://www.mayoclinic.com/health/vitamin-d/AN01864. In Canada, doctors often recommend 1000 IU per day as a potential cancer preventative.

Previously, I was taking 1000 to 1300 IU each day, every day, rain, snow, or shine, 365 days per year.

Plastic Bottles in Garbage

If concerned (aka intrusive) citizens continue to harass individuals who use disposable plastic water bottles, then those individuals might start hiding their empty bottles in the garbage, where they won’t be seen (in dark plastic garbage bags), rather than in recycle boxes out front of their homes.

The American Presidency: Selfish Candidates or Candidates for Selfishness?

The headlines today are “Mitt Romney quits after pouring $35 million of his own money into failed campaign.” Of course, we all know that Mitt Romney was running in the Republican primary, the race in which Republican voters choose which Republican leader will run against the Democrats for the U.S. presidency. But I do not hear anyone in the press pointing out that Romney’s $35 million would have been better spent helping the poor right here in the United States.

Romney’s courage (and extra money) would best serve the hopeless (the lost, and especially the lost at sea . . .).

Fitness and the Superbowl?

The Super Bowl was boring, as usual (you know . . . football) and had way too many TV commercials, as usual. And Tom Petty and the Heartbreakers’ half-time show was like brown snow — tired winter, dead flowers, bronchitis brought on by lifestyle — which brings me to my point: The half-time show’s producer (the company that put it on) asked for 600 volunteers (and got them), but I don’t know why anyone in their right mind would give their time for free to millionaires like Tom Petty and the Heartbreakers or to an event that makes millions of dollars (never mind the Super Bowl’s sponsors’ earnings, the ones who bought the commercials — they paid 2.7 million dollars for 20 seconds of air time).

Makes me wonder about Mankind. With all those millions of dollars floating around, why did 600 Arizonans work for free?

Truth is Ugly

A quote from John Updike’s book Seek My Face, page 48:

Truth is ugly. We possess art lest we perish of the truth. The only virtue left in this day and age is courage before the hopeless.

He means your courage best serves the hopeless.
