Fast food increases the risk of infertility in women
A group of Australian and British scientists has concluded that love for fast food and elimination from the diet fruit nutrition can lead to difficulties in conceiving among women of reproductive age. Their findings, published in the journal Human Reproduction, the researchers made based on observations of more than five thousand women trying to conceive.
A couple is considered infertile if a pregnant woman does not occur within one year of regular sexual intercourse without contraception. The inability to conceive a child can be connected not only to the absolute sterility, which is caused by incurable changes in the reproductive system. Among the factors influencing fertility in couples, isolated alcohol abuse, smoking, drug use and obesity - both women and men.
We are trying to have a baby couples are advised to maintain a healthy lifestyle: eat right, give up bad habits and increase physical activity. Nevertheless, until now studies of the association between dietary habits healthy fertile women and the ability to become pregnant has not been. Authors of new work examined the results of the survey 5598 residents of the UK, Australia and New Zealand between the ages of 18 to 43 years, carried out at the reception of obstetricians in early pregnancy (14-16 weeks) of their first pregnancy. Patients were told how long they were trying to get pregnant, and that was part of their diet for a month prior to conception - individual questionnaire for fresh fruit, vegetables, fish and fast food. These data were compared with the period during which the couple is trying to conceive a child.
Among all respondents in about 8 percent of the group were infertile couples, however, among those who rarely ate fruit, a long time could not conceive 12 percent of women. Of those who ate fast food four times a week or more, in a fruitless search were 16 percent women. On average, lovers of burgers and pizza became pregnant a month later, than those who adhered to a healthy diet. Three to four servings of fruit per day, on the contrary, accelerated the birth by an average of two weeks. Oddly enough, the number of greens and fish in the diet had no effect on the timing of the pregnancy.
"The survey results show that a healthy diet that includes fruits and at least a quick cooking, has a positive effect on fertility and reduces the time it takes for a woman to get pregnant" - says the findings lead author Clare Roberts.
How exactly fast food, "lay" conception, scientists still do not know. The authors of earlier studies suggested that the fatty acids contained in vegetable and animal fats and oils may adversely affect the egg. In addition, an abundance of sugar, salt and fat can affect the metabolism.
In the new work the researchers note the importance of a balanced diet for women who are trying to get pregnant - and even those who are not being treated for infertility. In the future, according to the authors, it is necessary to carry out the study and taking into account other dietary groups.
