Low-carbs to fight prostate cancer?
http://www.nutraingredientsusa.com/n...ws.asp?id=7536
Low-carbs to fight prostate cancer? 10/28/03 - A low-carbohydrate diet may be more effective than reducing fat intake for prevention of prostate cancer, suggests a laboratory study by researchers in the US. Previous studies have suggested a link between the amount of saturated fat in the diet and the risk of progression to advanced prostate cancer. But Ada Elgavish and colleagues from the University of Alabama at Birmingham found that carbohydrate intake may be more significant for men wishing to delay progression to advanced prostate cancer. "In the low-fat versus low-carbohydrate debate, we're finding that under conditions in which diet is provided ad libitum, a diet with fewer carbohydrates may be more effective in preventing progression to advanced, lethal prostate cancer than a diet with low fat content," said Dr Elgavish, lead author of the study, presenting the research at this week's AACR meeting, Frontiers in Cancer Prevention Research. "However, the results of this study are preliminary. Men should talk to their doctors before changing their diets," she added. The investigators compared the relative risk of developing advanced prostate cancer with a low-carbohydrate or a low-fat diet provided ad libitum (as much as wished), beginning before tumours developed and continuing until middle age. The study was carried out in TRAMP mice, biologically engineered to develop prostate cancer after puberty, developed by Dr Greenberg and associates at Baylor College of Medicine in Houston. Two groups of TRAMP mice were fed diets containing the same amount of calories, with either 10 per cent or 45 per cent fat (mostly lard). Carbohydrates, mostly corn starch and sucrose, replaced fat in the low-fat diet. Researchers measured food intake and body weight throughout the 23-week study. After the onset of middle age, mice fed the 45 per cent fat diet had a consistently higher body weight due to higher body fat. When the study ended, 95 per cent of the mice fed the 45 per cent fat diet had survived, compared with only 68.2 per cent of those fed with the 10 per cent fat diet. In addition, the percentage of mice with advanced prostate cancer in the 45 per cent fat group was one-third of that in the group fed the 10 per cent fat diet, reported the researcher. If the results are confirmed in humans, they could provoke a shift in thinking on prostate cancer prevention. Last year researchers from the Fred Hutchinson Cancer Research Center reported finding decreased risk for late-stage prostate cancer in men on low-fat and moderate calcium diets. Numerous other studies support a low-fat, high fibre diet, (advised by the Pritikin programme), to keep prostate cancer at bay. The new study suggests more research is needed to clarify advice for prostate cancer patients. http://www.aacr.org/2003prevention.asp |

First off this is mice. There have been other things that worked in mice but not humans.

"Patricia Heil" ha scritto nel messaggio ... First off this is mice. There have been other things that worked in mice but not humans. Yeah, this is ridicolous Rats and mice have nothing to do with humans with respect to trophic features They belong to a difference class compared to primate humans They are not adapted to an high carb diets of fruits, berries, vegetables, nut and fish In fact, while humans handle fructose quite well, fructose is quite dangerous to mice, but we know that primates eat fruits whereas I have never seen rats eating a banana As Steve Harris says "If you're a rat, you shouldn't eat fructose. Next rat that comes to me for a health consultation, I'll be sure and council him very well on the issue" So please, don't even post studies on rats or mice that are supposed to be used for human health, they're cruelty useless and if one is going to change his/her diet because of rats experiments then they become even dangerous !!

Low-carbs to fight prostate cancer?
This wouldn't surprised me.. Prostate cancer and male pattern baldness
are two sides of the same coin.. It's argued that that same coin is related to PCOS in women, which as we know is primarily an insulin resistance ailment. I've seen a few papers recently that hypothesise about the link between MBP and insulin resistance.. We know low carb diets are beneficial for people with insulin resistance, so I don't think it's a big stretch to think that low carb diets may be beneficial for the prostate as well (and hairloss? let's hope). When insulin goes up, SHBG goes down, and free T goes up. More free t means more DHT and estrogen, which affects the prostate. |

Low-carbs to fight prostate cancer?
There are several classes of carbohydrates, the refined sugars are
carbohydrates but so are the beans and other legumes which are more complex and have a low clycemic index. Practically everything we eat contains carbohydrates. "Duane Storey" wrote in message om...
