The myth of fiber being healthy continues to crumble.

A high-fiber diet and increased frequency of bowel movements are associated with greater, rather than lower, prevalence of diverticulosis. Hypotheses regarding risk factors for asymptomatic diverticulosis should be reconsidered.

Many epidemiologic studies have examined the relationship between fruit and vegetable intake and the incidence of colon and/or rectal cancer,[119] with considerable variation in findings. Perhaps the most definitive analysis to date is a prospective study that examined dietary intake data based on food frequency questionnaires from 88,764 women in the Nurses' Health Study and 47,325 men in the Health Professionals Follow-up Study.[120] The study included a total of 1,743,645 person-years of follow-up, 937 cases of colon cancer, and 244 cases of rectal cancer. On the basis of analyses adjusted for numerous covariates, the authors found no association in women or men between overall fruit and vegetable consumption and the risk of colon or rectal cancer. Associations were not observed when the data were examined for subgroups of fruits or vegetables (with the exception of legumes, which were associated with an increased risk of colon cancer in women) or individual fruits or vegetables (with the exception of prunes, which were associated with an increased risk of colon cancer in men). Results did not change when data were examined by vitamin use status, smoking status, or family history of CRC, nor were elevated risks seen when individuals with very low levels of fruit and vegetable consumption were compared with those having the highest levels. For women and men combined, the covariate-adjusted RR of colon cancer associated with one additional serving of fruits and vegetables per day was 1.02 (95% CI, 0.98–1.05); the comparable RR for rectal cancer was 1.02 (95% CI, 0.95–1.09).

re: Bad Wigins

So we should avoid fruits and vegetables? Sounds like sound nutritional advice.

This should top the list for "what I learned on letsrun.com today".

That cancer.gov site is giving the exact opposite advice of what you usually say, Bad Wigins.

If only there were other reasons to eat fruits and vegetables...oh wait.

find an example of me saying "there is an association in women or men between overall fruit and vegetable consumption and the risk of colon or rectal cancer"

Then the NCI will indeed be contradicting me by saying there's not.

re: uh....

You can eat them because they taste good, or for vitamins A and C.

But you don't need them in the crazy fiber-happy amounts recommended in the past few decades. You can get all the vitamin A and C you need from a single small orange and a small carrot. Of course you can also get plenty from liver, without eating any fruits or vegetables at all.

re: Bad Wigins

fiber clears estrogen from the body and so

reduces the risk of ER+ breast cancer and it's recurrence.

the study you cite did not partial out vitamin D status or red meat intake.

re: Bad Wigins

lol at basing how you eat on food frequency questionnaires and correlations.

We all really can't know what to think until t-rex weighs in, then we will know the opposite is true. Did we lose our beloved t-rex to another ice age? T-rex, oh t-rex.

That's one tiny part of the website you linked. Most of it is talking about things like cutting down on red meat or eating lower fat diets. Is that something you do, or did you just ignore everything that contradicted you?

re: HHEE

Avoiding high fat and red meat doesn't contradict me, it's completely irrelevant. You don't have to eat fiber to avoid red meat and fat. Therefore I did not quote the information in this thread about fiber.
