Consuming higher amounts of Vitamin D—mainly from dietary sources—may help protect against developing young-onset colorectal cancer or precancerous colon polyps, according to the first study to show such an association.
The study could potentially lead to recommendations for higher vitamin D intake as an inexpensive complement to screening tests as a colorectal cancer prevention strategy for adults younger than age 50.
While the overall incidence of colorectal cancer has been declining, cases have been increasing in younger adults—a worrisome trend that has yet to be explained.
"Vitamin D has known activity against colorectal cancer in laboratory studies. Because vitamin D deficiency has been steadily increasing over the past few years, we wondered whether this could be contributing to the rising rates of colorectal cancer in young individuals," said Ng, director of the Young-Onset Colorectal Cancer Center at Dana-Farber. "We found that total vitamin D intake of 300 IU per day or more—roughly equivalent to three 8-oz. glasses of milk—was associated with an approximately 50% lower risk of developing young-onset colorectal cancer."
The association was stronger for dietary vitamin D—principally from dairy products—than from vitamin D supplements. The study authors said that finding could be due to chance or to unknown factors that are not yet understood.
Interestingly, the researchers didn't find a significant association between total vitamin D intake and risk of colorectal cancer diagnosed after age 50. The findings were not able to explain this inconsistency, and the scientists said further research in a larger sample is necessary to determine if the protective effect of vitamin D is actually stronger in young-onset colorectal cancer.

My guess is that too few young people have little time outside without sunscreen or exposed skin.
Probably all those career moms that refused to breastfeed.
My doctor says that milk fat is what kills you. Can you get dairy with high Vitamin D and low or no fat?
“young-onset colorectal cancer”
Is that a serious problem now?
And fewer people drink real milk, instead of milk made from God knows what
Strangest thing, I hated milk all my life and here in the last couple of months I can’t get enough of it. Whole milk. Hopefully I get off this kick soon.

They don’t actually add Vitamin D to milk. The pass the milk between 2 parallel glass plates being illuminated with UV. The UV converts the cholesterol in the milk into vitamin D.
I had no idea about that. That’s how they “fortify” milk?
not the same vitamin d they want to make prescription only?

It’s one of the healthiest habits.
After shifting from whole milk to skim the whole milk now tastes like drinking cream. Skim is OK once you get used to it.
The government forces milk sellers to add vitamin A to skim milk. Foods have more vitamin A than you need. It might cause bone problems.
Too bad the U.S. is not a civilized country where people could easily drink skim milk without added vitamins if they wished.
I hope I just go back to my no milk thing. I don’t know what made me get this cow on my back.
Yup. Simple isn’t it? And all it costs is the power for the UV lamp.
You and I are rare. Virtually everyone I knew drank milk like a sift when I was kid except for myself and my mother. Most everyone I know still drinks milk. Only milk I could drink as a kid was chocolate and I can’t stand even that now. Must be the texture. Oh yeah...and never drink any milk from a plastic cup.
I’ve been taking about 5,000 iu’s daily since last year but I question whether it’s a good form. Absorption is everything and alot of supplements do not absorb well at all and thus are a waste of money.
For a long time, people took 10 micrograms of vitamin D per day. Excess reduces vitamin k and gamma tocopherol.
I hadn’t even thought about that.
