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.  IANS

Marijuana Intake Can Impair Fertility in Females, Says Study

Female eggs exposed a psychoactive ingredient in marijuana have an impaired ability to produce viable embryos and are significantly less likely to result in a viable pregnancy, claims a study.

Marijuana, or cannabis, is the most commonly used recreational drug by people of reproductive age The rise in marijuana use has occurred at the same time that the percentage of THC (Tetrahydrocannabinol) ingredient in the drug has increased.

Currently, patients seeking infertility treatments are advised against cannabis use, but the scientific evidence backing this statement is weak.

“This makes it difficult for physicians to properly advise patients undergoing in vitro fertilization,” said study researcher Megan Misner from University of Guelph in Canada.

In the study, published in the Journal of the Endocrine Society, researchers treated cow oocytes, or female eggs, with concentrations of THC equivalent to therapeutic and recreational doses.

The oocytes were collected and matured into five groups: untreated, control, low THC, mid THC and high THC. For the findings, the eggs’ developmental rates and gene expression were measured.

The researchers evaluated the ability of embryos to reach critical stages of development at specific time points. With higher concentrations of THC, they found a significant decrease and delay in the ability of the treated oocytes to reach these checkpoints.

“This is a key indicator in determining the quality and developmental potential of the egg,” Misner said. THC exposure led to a significant decrease in the expression of genes called connexins, which are present at increased levels in higher quality oocytes.

Poorer quality oocytes, with lower connexin expression levels, have been shown to lead to a poorer embryo development. ”

This embryo would be less likely to proceed past the first week of development, and thus lead to infertility,” Misner said. According to the researchers, preliminary data also showed THC affected the activity of a total of 62 genes in the treatment groups compared with the non-treated groups.
