markd@toad-net.com - 08 Sep 2004 15:42 GMT Ok, do you suggest eating meat with less cholesterol, as this is at issue in this information?

Hmm yes cholesterol is bad. So human breast milk which is loaded with cholesterol is bad for infants. Why did god put cholesterol in human breast milk. To poison babies?? Or maybe for some strange reason babies and growing children require cholesterol but all of the sudden for no reason when they are done breast feeding they need 0 cholesterol and in fact it becomes poisonous and deadly? Only morons and ignorants like you could think that a vital nutrient is unhealthy.

Why do people develop lactose intolerance? Could it be natures way to say that you should stop sucking cholesterol because you aren't a baby anymore? Not to a moron like you. Your logic still sucks.

We produce milk for as long as someone keeps drinking it.

He asked what the article was about ..
He was told it is about cholesterol ..
You have a problem with that .. ?
The .. key .. is ..
If you have cholesterol .. you have .. blood .. very .. close .. by ..
So .. one might say .. ANY .. 'study' .. which refers TO .. 'cholesterol consumption' .. would .. mean .. meat / association consumption ..
Understand .. ?
So .. it .. would .. mean .. increased .. iron .. availability AND absorption ..
And since they have shown iron .. deprivation .. to be useful in cancer treatment .. and since iron is NOW being 'targeted' IN .. various .. cancers .. the association .. exists ..
I take em where I can get em ..
Chances .. are .. the study group was NOT .. 'lacto-ovo' .. to a large extent ..

Only morons >and ignorants like you could think that a vital nutrient is unhealthy. What exactly makes it a vital nutrient? We know it clogs arteries but what other things does do?
Not an Australian - 16 Sep 2004 06:12 GMT > What exactly makes it a vital nutrient? We know it clogs arteries but > what other things does do? It is vital to the nervous system where it is part of the myelin sheath which is composed of 4 part cholesterol, 3 parts phosphoglycerides, and 2 parts galactolipids in the adult human myelin sheath. It is the source of bile and all steroid hormones. It is part of the cell membrane where it affect membrane fluidity.
It is a vital nutrient to the cells and tissues though it synthesized by the organism. If the organism gets too much from both diet or internal synthesis to match it set point, it internal synthesis will be decreased. Or stated differently, the quantities synthesized vary inversely with dietary intake.
tintinet - 08 Sep 2004 22:59 GMT > So you advise eating animals low in saturated fats, that being the risk > factor at issue here? Ummm, to quote the abstract: "However, we did not observe an association of ovarian cancer risk with dietary fat intake, including saturated, monounsaturated, and polyunsaturated fatty acids..."
So no, saturated fats don't seem to matter. Just cholesterol.

Nutrient intake and ovarian cancer: an Italian case-control study.

OBJECTIVE: The role of selected macronutrients, cholesterol, and fatty acids in the etiology of epithelial ovarian cancer was analyzed using data from a case-control study carried out in five Italian areas between January 1992 and December 1999. METHODS: Cases comprised 1,031 women with incident, histologically confirmed epithelial ovarian cancer, admitted to the major teaching and general hospitals of the study areas. Controls comprised 2,411 women admitted for acute, non-neoplastic conditions to the same network of hospitals. Information on dietary habits was elicited using a validated food-frequency questionnaire including 78 food groups and recipes. Odds ratios (OR) and their corresponding 95% confidence intervals (CI) were computed by subsequent quintiles of nutrient intake. RESULTS: Direct associations with ovarian cancer emerged for starch intake (OR = 1.4 in the highest vs the lowest quintile of intake; 95% CI 1.1-1.8), while inverse associations emerged for monounsaturated (OR=0.7; 95% CI 0.5-0.9), and polyunsaturated (OR = 0.7; 95% CI 0.5-0.9) fatty acids. Among fatty acids, oleic (OR = 0.7; 95% CI 0.5-0.9), linoleic (OR = 0.7; 95% CI 0.5-0.9), and linolenic (OR = 0.8; 95% CI 0.6-1.0) acids were inversely related to ovarian cancer. When, however, six macronutrients were included in the same model, only the adverse effect of high starch intake remained significant. Results were consistent in separate strata of menopausal status, parity, and energy intake. CONCLUSIONS: Starch was directly associated, and unsaturated fatty acids were inversely associated, with ovarian cancer risk.

BACKGROUND: Dietary carbohydrates vary in their ability to raise blood glucose and insulin levels, which, in turn, influence levels of sex hormones and insulin-like growth factors. We analyzed the effect of type and amount of carbohydrates on ovarian cancer risk, using the glycemic index (GI) and the glycemic load (GL) measurement in a large case-control study conducted in Italy. MATERIALS AND METHODS: Cases included 1031 women with incident, histologically confirmed epithelial ovarian cancer, from four Italian regions. Controls included 2411 women admitted to the same hospital networks for acute, non-neoplastic conditions. Average daily GI and GL were calculated from a validated food frequency questionnaire. Odds ratios (OR) and the corresponding 95% confidence intervals (CI) were computed using multiple logistic regression. RESULTS: Ovarian cancer was directly associated with dietary GI (OR for highest versus lowest quartile = 1.7, 95% CI 1.3-2.1) and GL (OR = 1.7, 95% CI 1.3-2.1). The associations were observed in pre- and postmenopausal women, and they remained consistent across strata of major covariates identified. CONCLUSIONS: This study supports the hypothesis of a direct association between GI and GL and ovarian cancer risk and, consequently, of a possible role of hyperinsulinemia/insulin resistance in ovarian cancer development.

The largest and most comprehensive study on diet and breast cancer to date, studying over 5,000 women between 1991 and 1994, showed that women with the lowest intake of dietary fat had a significantly higher incidence of breast cancer than the women with the highest intake of dietary fat. It also found that women with the highest intake of starch had a significantly higher incidence of breast cancer than the women with the lowest intake of starch. The study found no evidence that saturated fat had any effect one way or the other on breast cancer, and that unsaturated fat had a significantly protective effect against breast cancer.
