Guest guest Posted February 1, 2006 Report Share Posted February 1, 2006 DNA damage eh! Who would have thought it (sarcasm). Isn't all illness caused by DNA damage? Jo Researchers believe they have discovered why eating lots of red meat can raise the risk of bowel cancer. Scientists at the Dunn Human Nutrition Unit and the Open University compared a red meat diet and a vegetarian diet. Their study, published in Cancer Research, found the red meat diet was associated with a higher level of damage to the body's DNA. Previous work suggests regular meat eaters are significantly more likely to develop bowel cancer. Almost 17,000 people die from the disease each year. Clues Last year the Dunn team published a study suggesting the chance of developing the disease was a third higher for people who regularly ate more than two portions per day of red meat compared with those who ate less than one portion per week. These combined discoveries ... may give us some clues about developing a screening test for very early changes related to the disease Professor David Shuker, Open University In the latest study the same Dunn team examined cells from the lining of the colon taken from healthy volunteers eating different diets. They found higher levels of DNA damage in the cells taken from people eating red meat. Work by the Open University team suggests the reason could be the presence of substances called N-nitrosocompounds, which form in the large bowel after eating red meat. Their work suggests that these compounds combine with DNA, and alter it so that it is more likely to undergo harmful changes or mutations that increase the likelihood of cancer Professor David Shuker, head of the Open University team, said: " These combined discoveries have allowed us to link red meat consumption to an increased risk of bowel cancer and may give us some clues about developing a screening test for very early changes related to the disease. " 'Moderation is key' Professor Colin Blakemore, chief executive of the Medical Research Council, which funded the research, said: " Large bowel cancer is the second most common cancer in western countries and nearly one million cases occur each year worldwide. " This latest study, together with the compelling epidemiological evidence published last year, is an important step towards understanding, and potentially preventing this common disease. " A spokesman for the charity Beating Bowel Cancer said: " The fact is a third of all cancers are linked to what we eat and we must not underestimate the importance of a well-balanced diet in the prevention of bowel cancer. " This study certainly seems to add further weight to previous evidence about the possible link between bowel cancer and a high consumption of red meat. " As with all dietary advice, moderation is key as we already know that a diet high in fat and red meat yet low in fibre, fruit and vegetables can increase the risk of developing this disease - currently the second biggest cause of cancer death in the UK. " Professor Annie Anderson, expert advisor to Bowel Cancer UK, said: " The new data not only provides further evidence of risk but also flags the importance of what we eat with our meat - for example, there is further risk with low fibre intakes. " Current data on eating trends suggests we are eating more fast foods, which we know are high in calories and fat and implicated as a cause of obesity and diabetes, but such cuisine may also be the very type of meals (high in meat - and meat products - and low in vegetables) that also contributes to bowel cancer risk.

Guest guest Posted February 1, 2006 Report Share Posted February 1, 2006 well, to be honest....no... depends on the illness... many, if not most illnesses have little to nothing to do with dna... things like cancers and certain viruses, yes, but, any bacteria, protozoan, er parasite, nope... cheers fraggle >heartwerk <jo.heartwork >Jan 31, 2006 11:52 PM > > Red Meat and Bowel Cancer > >DNA damage eh!

Quite simply, a missile defense shield is a net, made of magic, held in place by pixies. That's what it is, we have 70 pixies ready to go.. they're all wrapped up in special kevlar lining. They're in a bunker in Colorado ready to go up there and defend our country! And that's how it works, and it costs a lot of money folks. That doesn't cost $100. That's what a box-cutter shield would cost, that's what you guys seem to be wanting. " David Cross Quote Link to comment Share on other sites More sharing options...
Guest guest Posted February 1, 2006 Report Share Posted February 1, 2006 Well yes - but we were talking about degenerative illness (bowel cancer) not an infection.
