Oh give it up NA…   The Comapny pays me for my duties as a shopsteward whenever someone needs help and thats only during the working hours…It’s written into our Collective bargaining Agreement.It’s nothing like you who steals time at wrk to go post on the newsgroups .  And yes I do use a computer at work!! It’s hooked up with JDEdwards. Not something one would use to go on the internet with.

Yes, Vitamin supplements usually won’t net you much fibre intake.  Where I live it’s a real rarity to ever see much in the way of Organic produce during the winter months so I use a multiple source fibre supplement daily also.

I didn’t say it had to be raw…you can cook veggies. and yes you lose some nutrients, but you get the added benefit of the fiber (which you won’t get from vitamins).   Certainly I take a multi-vitamin as wel as calcium, but part of preventing cancer is the fiber intake.   – Hide quoted text — Show quoted text – >Well according to the latest poll the majority of us >don’t even get the RDA’s minium requirements. >Plus eating raw veggies isn’t always do able with IBD. >But definitly eating is always the best way to go. >Supplements aren’t meant to replace a good diet they are to complement a >good diet. > Or even better we could EAT broccoli! >>Well hopefully most of us use a multi -vitamin that contains a Brocolli >>concentrate. >>>  The vitamin issue isn’t as simple and clear cut as some people woud >>> suggest. >>> John >>>> It’s only one study but this one raises an eyebrow: >>>> EDMONTON – Antioxidant supplements like beta-carotene don’t help to >>>> prevent five gastrointestinal cancers, and may actually do harm, a new >>>> review suggests. >>>> Antioxidants include beta-carotene, selenium and vitamins A, C and E, >>>> which have long been touted as helping to prevent some forms of cancer. >>>> A review of 14 previous randomized trials on the vitamins appears as >>>> the >>>> cover story in the Oct. 1 issue of the medical journal The Lancet. >>>> Goran Bjelakovic of the University of Niss, Serbia and Montenegro, and >>>> colleagues from The Cochrane Hepato-Biliary Group said the supplements >>>> showed no protective effect compared to dummy pills for oesophageal, >>>> gastric, colorectal, pancreatic, and liver cancer. >>>> "We noted a substantially higher mortality in the antioxidant group >>>> than >>>> in placebo," the researchers wrote. >>>> The report’s authors aren’t sure what to make of the finding, saying >>>> more study is needed.

Response:

Well according to the latest poll the majority of us don’t even get the RDA’s minium requirements. Plus eating raw veggies isn’t always do able with IBD. But definitly eating is always the best way to go. Supplements aren’t meant to replace a good diet they are to complement a good diet.

"The vitamin issue isn’t as simple and clear cut as some people would suggest." John H. What is important is that the relationship between IBD and supplements(vitamins, minerals etc) IS as simple as l have suggested in previous posts. Navid.

Well hopefully most of us use a multi -vitamin that contains a Brocolli concentrate.

It’s only one study but this one raises an eyebrow: EDMONTON – Antioxidant supplements like beta-carotene don’t help to prevent five gastrointestinal cancers, and may actually do harm, a new review suggests. Antioxidants include beta-carotene, selenium and vitamins A, C and E, which have long been touted as helping to prevent some forms of cancer. A review of 14 previous randomized trials on the vitamins appears as the cover story in the Oct. 1 issue of the medical journal The Lancet. Goran Bjelakovic of the University of Niss, Serbia and Montenegro, and colleagues from The Cochrane Hepato-Biliary Group said the supplements showed no protective effect compared to dummy pills for oesophageal, gastric, colorectal, pancreatic, and liver cancer. "We noted a substantially higher mortality in the antioxidant group than in placebo," the researchers wrote. The report’s authors aren’t sure what to make of the finding, saying more study is needed. The risk is insignificant, according to Dr. David Jenkins, a professor nutritional science at the University of Toronto. "They’re not into the high risk or moderate risk category," said Jenkins. "They are in the grey area where we’re not really very sure whether this is a real effect." The study’s take-home message is, don’t bother taking antioxidants to prevent cancer, Dr. Linda Babeneck, head of gastroenterology at Sunnybrook and Women’s College Hospital in Toronto. "What we would say to an individual I think is, don’t take them for this reason, because there’s no good evidence that they prevent these five cancers," said Babeneck. One fan of the supplements, who studies, sells and takes the vitamins, said she’s not convinced by The Lancet paper. "We could fill this whole store with all the studies that are done on the benefits of antioxidants," said Sheryl Jeffrey of Planet Organic Market in Edmonton. "Then on the other hand, we have that one study that says they’re not good, so you have to balance that." All the study shows definitely is if you want to prevent gastrointestinal cancers, you’re better off eating broccoli. http://www.cbc.ca/story/science/national/2004/09/30/antioxidants04093…
