Before treatment, the couple completed detailed questionnaires on their eating habits over the past month. When the researchers analysed the data, they identified two common diet patterns among the women. 1). The Mediterranean diet – defined as high in vegetables, vegetable bits, fish and beans, but low in snack foods and 2). The health conscious diet – which is high in fruits, vegetables, whole grains, beans and fish, and low in meat and snack foods.
The researchers found there was no link between the health-conscious diet and rates of pregnancy. But, the group that most closely adhered to the Mediterranean diet was more likely to become pregnant. The researchers did not assess pregnancy outcome, so the diet's relationship to the ultimate success of fertility treatment is not clear.
The Mediterranean and health-conscious diets had many similarities, but there are a few potential reasons why the former may affect fertility treatment success said the researchers.
One is the high intake of vegetable oils in the Mediterranean diet. Researchers noted that the Omega-6 fatty acids in these oils are the precursors to hormone-like substances in the body called prostaglandins. Prostaglandins, in turn, are involved in the menstrual cycle, ovulation and pregnancy maintenance.
In addition, the study found that women who most closely followed the diet Mediterranean way had higher levels of vitamin B6. One previous study found giving vitamin B to women who were having difficulty getting pregnant increased their chances of conception.
Still, diet is part of a person's overall lifestyle and the study could not account for all of the factors that could clarify the connection between the natural ways to Increase fertility Mediterranean diet and pregnancy rates
Eating a diet of plenty of oily fish daily can protect women against infertility, says a new study. Researchers have carried out the study of 70,000 nurses and found those who ate the most tuna, salmon, mackerel and other fish high in omega-3 fatty acids were nearly 22 per cent less likely to develop endometriosis which is known to causes infertility.
However, the study found that those whose diets were heavily laden with harmful transfats – chemically altered vegetable oils – found in thousands of products from cakes and biscuits to pies and chips were 48 per cent more at risk of developing endometriosis. The condition arises when cells normally found in the womb lining attach themselves to other parts of the pelvic area, causing inflammation and often leading to infertility.
The study, the largest to have investigated the link between diet and endometriosis, followed the nurses for 12 years from 1989. It found while the total amount of fat consumed did not matter, the type did.
Gynaecologist Dr Stacey Missmer, of Harvard Medical School, Boston, said her findings, not only suggest that diet may be important in the development of endometriosis but also provide more evidence for eliminating trans fats, which are used to bulk up foods and increase their shelf life.
“Millions of women worldwide suffer from endometriosis. Many have been searching for something they can do for themselves, or their daughters, to reduce the risk of developing the disease. These findings suggest dietary changes may be something they can do. The results need to be confirmed by further research, but this study gives us a strong indication that we are on the right track in identifying food rich in omega-3 oils as protective for endometriosis and trans fats as detrimental,” she said.
The study is published in the 'Human Reproduction' journal.
