NEW YORK (Reuters Health) – Higher levels of vitamin D in the blood may help protect both men and women from cancers of the colon and rectum, confirm results of the largest study ever conducted on the topic.
Among more than 1200 people who developed colorectal cancer and an equal number who did not, researchers found that those with the highest levels of vitamin D in their blood had a nearly 40 percent reduced risk of developing colorectal cancer compared to those with the lowest levels.
The findings from the EPIC study - short for European Prospective Investigation into Cancer and Nutrition -- confirm previous findings from smaller studies conducted largely among North American populations.
The EPIC findings "support a role for vitamin D" in the causes of colorectal cancer, EPIC investigator Dr. Mazda Jenab of the International Agency for Research on Cancer in Lyon, France, told Reuters Health.
"But this has to be balanced with caution regarding the potential toxic effects of too much vitamin D and the fact that very little is known about the association of vitamin D with either increased or reduced risk of other cancers," Jenab said.

More D ping.
Drink your Moo Juice kiddies!
Does that mean that if you've got vitamin D up the wazoo, you're protected from colo-rectal cancer?!
:)
Hey. Just wanted to thank you for your mrsa, D, and other health related posts. I enjoy them.
Or is that “out the wazoo?”
Thanks. I hope someone benefits from them.

I for one did. I now take 6000 IU’s of D daily and manuka honey has all but cleared up and MRSA infected surgical wound from October.
Maybe I should say screw politics and become a member of a health website. But I enjoy the well rounded nature of FR. Thanks.

if this were true... then finding people whose diet naturally has high sources of vitamin D should show a low incidence of colon cancer

from the wiki:

Natural sources of vitamin D include:[2]
* Fish liver oils, such as cod liver oil, 1 Tbs. (15 ml) provides 1,360 IU (one IU equals 25 ng)
* Fatty fish species, such as:
o Herring, 85 g (3 ounces (oz)) provides 1383 IU
o Catfish, 85 g (3 oz) provides 425 IU
o Salmon, cooked, 100 g (3.5 oz]) provides 360 IU
o Mackerel, cooked, 100 g (3.5 oz]), 345 IU
o Sardines, canned in oil, drained, 50 g (1.75 oz), 250 IU
o Tuna, canned in oil, 85 g (3 oz), 200 IU
o Eel, cooked, 100 g (3.5 oz), 200 IU
* A whole egg, provides 20 IU
* Beef liver, cooked, 100 g (3.5 oz), provides 15 IU
* UV-irradiated mushrooms (Vitamin D2)[30][31]
In the United States (U.S.), the 100% Daily Value used for product labels is 400 IU/day and typical diets provide about 100 IU/day. Although milk is usually fortified, the average daily consumption by most Americans is insufficient in obtaining levels of vitamin D recommended by various medical authorities.[32] While adequate intake has been defined as 200 IU/day for ages infant to 50, 400/day for 51-70, and 600/day over 70, the American Academy of Pediatrics argues that these recommendations are insufficient and recommends a minimum of 400 IU, even for infants.[33] The NIH has set the safe upper limit at 2000 IU, but acknowledges newer data supporting a UL as high as 10,000 IU/day.[34] The Institute Of Medicine is revisiting vitamin D and calcium recommendations with a report expected to be released in spring 2010.

considering the natural sources, i would look at eskimos and maybe the japanese to compare colon cancer rates
There’s probably not enough D in milk, unfortunately. Even to get the RDA (which is probably very low) you would have to drink 2 to 4 cups per day of fortified milk to get that amount. Sunlight is probably the best way, or supplimentation (I take 1000 iu per day now).
Of course, you would also have to factor in any gene they might have which might protect them from colon cancer.
I think the story with the Eskimos is that their diet has traditionally been much of fish and animals that eat fish. That’s probably far less true today. In any case, you’d have to know their blood levels of vitamin D to make any judgment.

These are yummy!
