A study of 185, 000 post menopausal women from the University of Chicago – one of the largest of its kind – suggests that just two glasses of wine a day can increase the risk of breast cancer by more than a half. A single glass of wine a day raises the risk by almost a third.

The study which was presented at the American Association for Cancer Research’s annual conference in San Diego revealed a close link between drinking patterns and the development of the most common form of breast cancer – a form that is fuelled by the sex hormone oestrogen. It is thought that alcohol stops the liver from breaking down oestrogen, the hormone that can fuel breast cancer. The link applied to wine, beer and spirits but beer raised the threat slightly more than wine and wine proved more dangerous than spirits. Overall women who had more than one alcoholic drink a day were seven percent more likely to develop breast cancer than those who were non drinkers. Two drinks raised the risk by 22 per cent and three increased the risk by 51 per cent.

 

This study adds to the growing evidence that links alcohol to a disease which kills more than a thousand women a month and experts believe that alcohol may be the main reason why rates of breast cancer are surging in the UK. Drinking is also blamed for increasing numbers of women suffering fertility problems.

In May 2008 the National Childbirth Trust called on manufacturers to put warning labels on bottles made with a Bisphenol A because they believe that it may be putting young children and babies at risk.

Bisphenol A mimics the hormone oestrogen and can pass from clear plastic into milk, water and juice – especially when containers are heated in ovens or microwaves. In the US studies have linked exposure to low levels of Bisphenol A with fertility problems, breast cancer and early puberty. Canada is phasing out bottles made with Bisphenol A and in the US the world’s largest retailer – Walmart – has banned them from its shelves.

 

For over a decade there have been concerns about Bisphenol A but it is still used in nine out of ten bottles. Babies are thought to be particularly vulnerable to exposure because they are still growing.

A recent study by British scientists from the University of Birmingham on the impact of memory of food on snacking has suggested that if you are feeling hungry but want to lose weight remembering your last meal can suppress your appetite and reduce your desire to snack on junk food. The researchers also showed that concentrating on your food when you eat – rather than grabbing a snack on the go or eating while you watch television – makes you less likely to get hungry later on.

These findings suggest that women who want or need to lose weight can teach themselves to be less hungry and that complementary therapies such as hypnotherapy could help.
