Womens Health Initiative Health and Diet Study

WHI Women’s Health Initiative Diet TrialLow-Fat Dietary Pattern and Risk of Breast Cancer, Colorectal Cancer, and Cardiovascular Disease: The Women’s Health Initiative (WHI) Randomized Controlled Dietary Modification Trial.

"Breast cancer rates were 9% lower in women in the Dietary Change group" the study shows that those women with higher changes in saturated fat consumption had even better rates of reduction. This figure is considered statistically insignificant as it could be down to chance.

London Nutritionist Yvonne Bishop-Weston foods for life questions the validity of conclusions of the diet trial.

* Participants reduced saturated fat - they didn't cut it out.
* The difference in fat intake between the Dietary Change and Comparison groups declined over time, from 11% at year one to 8%. 8% is lower than the 9% difference in lowered breast cancer that they claim is statistically insignificant.
* There seems an apparent lack of focus on cutting down meat.
* Focus was on low fat rather than bad fat - lack of essential fats in the diet could be almost as detrimental as too much saturated fat.
* No mention of cutting out dairy from the diet is mentioned.
* It's reported that participants had a more challenging time with increasing grains and no mention of replacing simple processed carbs with more complex wholemeal carbohydrates.

Yvonne say "It's a shame that this massive 8 year study missed the opportunity to focus on a truly healthy diet rather than erroneously just focussing on "Low Fat Diets". Studies on vegetarian/vegan diets show significant benefits and lower risks especially if an adequate nutritional intake of vitamin B12 and essential fats is maintained.

WHI Conclusion
A low fat dietary pattern may have some potential for reducing breast cancer risk, particularly in women consuming a high fat diet. However, the current findings are not strong enough to make a recommendation that most women should focus on low-fat dietary patterns to prevent breast cancer. These findings indicate that a low-fat diet provided no protection from colorectal cancer and should not be recommended for that purpose. The low-fat diet did not specifically focus on reducing saturated fat, had only a small effect on blood cholesterol, and did not reduce the risk of heart disease. However, the WHI results suggest that women who achieved greater reductions in saturated fat or trans fat, and higher intakes of fruits and vegetables, might experience a reduced risk of heart attacks. Overall, the WHI low fat dietary pattern is not inconsistent with the USDA Dietary Guidelines for Americans 2005 and remains a healthy option for postmenopausal women in general.

Scotsman.com News - Health - Red meat diet damages DNA and adds to cancer risk, expert warns


EATING red meat alters your DNA and may lead to an increased risk of developing bowel cancer, scientists said yesterday.

Chemical compounds formed while digesting meat can cause DNA to mutate and increase the likelihood of cancerous cells developing.

People who eat two portions or more of red meat a day suffer significantly more DNA damage to the cells of their colon than those who follow a largely vegetarian diet or eat red meat less than once a week.

The research, published in Cancer Research journal, found that people who eat large quantities of red or processed meat are more likely to develop cancerous tumours in their large bowel.

N-nitroso compounds are formed in the large bowel after eating red meat and can attach themselves to DNA and cause it to mutate.

Scientists compared the cells of healthy volunteers, some of them on a vegetarian diet, others eating large quantities of meat and over a period of two weeks were able to pinpoint DNA damage.

Professor David Shuker, who led the research from the Open University department of chemistry in Milton Keynes, said: "We hope to be able to develop a simple screening test so that we can spot DNA damage and advise people to change their diets by cutting down on the amount of red meat they eat before cancer develops.

"We advocate a balanced diet, not vegetarianism as there are some nutrients that are best got from meat.

"This research showed damage in healthy people so you can imagine that if someone was predisposed to bowel cancer or had an inflamed gut the effects would be more severe.

"People also have varying abilities to repair the damage to their intestines.

"I advise a balanced diet as there is not much evidence that vegetarianism lowers your risk of bowel cancer."

Eating a low-fibre diet combined with high red meat content also elevates the risk of bowel cancer because digested food and chemicals stay in the gut longer. Eating more fibre may help repair damage done to the colon.

Research by the Medical Research Council published last year showed the chance of developing colorectal cancer was a third higher in people who regularly ate more than two portions of red or processed meat a day compared to those who ate less than one portion a week.

Bowel cancer charities welcomed the research yesterday and supported the consumption of red meat in moderation.

Professor Annie Anderson, from the Centre for Public Health Nutrition Research at the University of Dundee and adviser to Bowel Cancer UK, said the rise of ready meals contributed to the trend.
