Eating lot of rice may advance start of menopause
London, May 1: Eating lots of refined carbohydrates, particularly white pasta and rice, may advance the start of menopause by about one-and-a-half years, warns a study.
The findings, published in the Journal of Epidemiology and Community Health, showed that high intake of healthy foods, such as oily fish and fresh legumes, such as peas and green beans, was associated with a later onset of menopause.
"There are a number of causes that have been considered for the relationship between age and start of menopause, such as genetic factors or behavioural and environmental exposures. But there are fewer studies that look at the impact of diet," said study lead author Yashvee Dunneram, a postdoctoral researcher at the University of Leeds in Britain.
The study used data from more than 14,150 women living in Britain. Along with a detailed diet questionnaire, an initial survey collected information on reproductive history and health.
When a follow up survey and questionnaire were conducted four years later, the researchers were able to assess the diets of the women who had experienced the onset of a natural menopause in the interim.
The average age at the start of the menopause for women in Britain is 51 years.
More than 900 women between the ages of 40 and 65 had experienced a natural start of their menopause at the time of the follow-up survey, meaning they had not had menstrual periods for at least 12 consecutive months and menopause had not been brought on by such things as cancer, surgery or pharmaceutical treatments.
Analysis of their diet showed that high intakes of oily fish were associated with a delayed start of menopause by nearly three years.
A diet with lots of refined pasta and rice showed that menopause was more likely to occur one-and-a-half years earlier than average.
"The age at which menopause begins can have serious health implications for some women," study co-author Janet Cade, Professor at the University of Leeds, said.
Previous studies have suggested that earlier onset of menopause is associated with lower bone density, osteoporosis and increased risk of cardiovascular diseases, while later menopause has been associated with a higher risk for breast, ovarian and endometrial cancers.
Even though the new study is observational and cannot prove any cause, the researchers offer some possible explanations behind their findings, according to a BBC report on Tuesday.
For example, legumes contain antioxidants, which may preserve menstruation for longer.
Similarly, omega-3 fatty acids found in oily fish, also stimulate antioxidant capacity in the body.
On the other hand, refined carbs increase the risk of insulin resistance, which can interfere with sex hormone activity and raise oestrogen levels.
This might increase the number of menstrual cycles leading to the egg supply running out faster, the BBC report said.

England sticking with Key, McCullum and Stokes despite Ashes humbling
London (AP): England is not sacking anybody following the 4-1 Ashes loss in Australia.
A review of the tour by the England and Wales Cricket Board, announced within hours of the final match in January, was concluded on Monday. Firing people would “be the easy thing to do,” ECB chief executive Richard Gould said but he insisted, "This is not the time to throw everything out."
Managing director Rob Key, coach Brendon McCullum and captain Ben Stokes kept their jobs after the best England side to go to Australia in 14 years lost the Ashes in 11 days with two games to spare.
“Moving people on can sometimes be the easy thing to do. That's not the route that we're going to take,” Gould said. “I've seen the driving ambition and determination that we're lucky enough to have within our leadership group to take the lessons from the Ashes and move forward.”
Gould previously was the chief executive of Bristol City soccer club and said the ECB would not follow the same route as soccer's hire-and-fire culture.
“Cricket is a very unique sport in that it takes a team of leadership ... it's not like football where there's a single point of failure or success with a manager," he said. He added the ECB would not “select or deselect management based on a popularity campaign.”
The main criticisms of England's tour were poor preparation, player misbehavior, and selection mistakes.
At a press conference at Lord's, Gould and Key said McCullum and Stokes have not had a “bust up,” they did not want McCullum to “completely change” but “to evolve,” the behavior of some players was “unprofessional,” there will be more consequences for underperforming, and a commitment to “better long-term planning” ahead of major test series.
Some changes were already implemented for the Twenty20 World Cup, where England reached the semifinals. Gould implied that performance saved McCullum.
Key acknowledged that England supporters would be disappointed to see the management team go unpunished.
“I know people want punishment and that people then should be sacked for that,” Key said. “That doesn't mean we don't feel like we've gone through some serious pain: Brendon, myself, Ben. It's been as tough a time as I think I've had.”
