Scientists claim that women who have breast cancer and who regularly eat cheese, yoghurts or ice cream may be decreasing their chances of survival according to a new survey done by Kaiser Permanente research institute.
According to Lead researcher, Candyce Kroenke, who looked at the records of 1,500 women diagnosed with breast cancer between 1997 and 2000, “Women consuming larger amounts of high-fat dairy had higher breast cancer mortality as well as higher all-cause mortality and higher non-breast cancer mortality. She said they had a 49% higher chance of death from breast cancer.
American scientists suspect that the hormone estrogen found in milk and other dairy foods encourages tumor growth.
The hormone connection might apply beyond breast cancer. A 2012 study found that drinking more whole milk was associated with worse survival among men with prostate cancer, while skim milk was associated with higher survival.
“This is a very well-done study by highly regarded researchers,” said Dr. Michelle Holmes, associate professor of medicine and epidemiology at Harvard Medical School and Harvard School of Public Health, who was not involved in the research.
Dr. Holmes went on to say that it advances scientists’ understanding of how diet affects breast cancer, and presents women with a simple dietary choice: “It’s for each woman to decide, but if you don’t eat high-fat dairy you can get the same nutrients from other sources,” including low-fat versions, she said.
According to figures from the study, there are around 50,000 new cases of breast cancer among women every year and one in eight will likely develop breast cancer.
There is already some evidence that following a healthy diet may improve the survival chances of cancer and prevent it from returning. But this is the first study to show such a strong link between dairy products and breast cancer.
According to the scientists if you eat one ice cream or yoghurt a day it could hinder your chance of survival if you have breast cancer. Those with the disease who eat a single portion, daily, of a product containing full-fat milk could be 50 per cent more likely to die.
Susan Kutner, chair of the Kaiser Permanente Northern California Regional Breast Care Task Force, said: “Women have been clamoring for this type of information. They’re asking us, ‘Tell me what I should eat?’ With this information, we can be more specific about recommending low-fat dairy products.
