A recent study conducted by the Food, Nutrition, Development, and Mental Health research team at the Universitat Rovira i Virgili (URV) has unveiled a significant link between adhering to a heart-healthy diet and a reduced risk of pregnancy loss in women undergoing infertility treatments. Specifically, the study focused on the impact of various healthy dietary patterns on the well-being of women receiving infertility treatments.
The research findings suggest that following the diet recommended by the American Heart Association (AHA), which is rich in fish, whole grains, omega-3 fatty acids, and folic acid, prior to pregnancy can lead to a remarkable 13-15% decrease in the risk of miscarriage. These results were recently published in the reputable journal JAMA Network Open.
Infertility is a global health concern affecting couples worldwide, with a prevalence estimated at 12% to 15% and steadily rising. This issue is influenced by various lifestyle and environmental factors, including air pollution and obesity. While existing scientific evidence indicates that certain foods and nutrients can enhance the outcomes of infertility treatments for women, the role played by dietary patterns has remained largely unknown.
To address this knowledge gap, a multidisciplinary research team comprising experts in nutrition, epidemiology, and environmental health embarked on an investigation to determine whether women’s adherence to healthy dietary patterns, designed to prevent cardiovascular and chronic diseases, is associated with improved results in infertility treatment.
The study involved a thorough analysis of dietary patterns and reproductive outcomes. Researchers examined a sample of 612 women aged 18 to 45 who had undergone two of the primary infertility treatments: intrauterine injection and in vitro fertilization, totaling more than 1,500 cycles. They first assessed the diet of both women and their partners prior to assisted reproduction treatments. Subsequently, they investigated the extent to which these women followed one of eight globally recognized healthy dietary patterns. Notably, those who closely adhered to the AHA-recommended diet had a significantly lower risk of miscarriage during assisted reproduction cycles.
The AHA dietary pattern is characterized by its diversity and includes no restrictions on any food group. This study confirms that regular consumption of nutrients and foods such as fish, whole grains, omega-3 fatty acids, and folic acid is associated with a reduced risk of miscarriage during assisted reproduction, making them essential for human reproduction, according to Albert Salas-Huetos, a lecturer at the URV’s Preventive Medicine Unit and the principal researcher at the Biomedical Research Centre (Cyber) of the Carlos III Institute and the Pere Virgili Health Research Institute.
While similar trends were observed in other healthy dietary patterns studied, the plant-based vegetarian diet stood out as an exception. The difference between the AHA-recommended heart-healthy diet and the vegetarian diet lies in the absence of foods such as fish and meat, which contain essential nutrients like vitamin B12 and omega-3 fatty acids.
This collaborative research, conducted in partnership with the University of Girona and the Massachusetts General Hospital, provides valuable insights that could inform future studies investigating the effects of nutritional interventions on human fertility. It underscores the significance of dietary choices in the context of reproductive health, particularly for women undergoing infertility treatments.

Frequently Asked Questions (FAQs) about Infertility Treatment Diet
What is the key finding of the study mentioned in the text?
The study reveals that following a heart-healthy diet, as recommended by the American Heart Association (AHA), which includes fish, whole grains, omega-3 fatty acids, and folic acid, can lead to a significant 13-15% reduction in the risk of miscarriage in women undergoing infertility treatments.
What are some of the characteristics of the heart-healthy diet recommended by the AHA?
The AHA-recommended diet is diverse and does not restrict any food group. It is characterized by a high consumption of fish, whole grains, omega-3 fatty acids, and folic acid. This combination of nutrients is associated with a lower risk of miscarriage during assisted reproduction cycles.
How was the research conducted, and what was the sample size?
The research involved the analysis of 612 women aged 18 to 45 who had undergone infertility treatments, including intrauterine injection and in vitro fertilization, totaling more than 1,500 cycles. The study assessed the women’s diets before assisted reproduction treatments and their adherence to various healthy dietary patterns.
Are there other healthy dietary patterns that showed similar trends in reducing miscarriage risk?
Yes, the study indicated that several other healthy dietary patterns exhibited similar trends, except for the plant-based vegetarian diet. The difference between the AHA-recommended diet and the vegetarian diet lies in the absence of foods like fish and meat, which contain essential nutrients such as vitamin B12 and omega-3 fatty acids.
What implications do these findings have for women undergoing infertility treatments?
These findings emphasize the importance of dietary choices for women undergoing infertility treatments. Following a heart-healthy diet, rich in specific nutrients, can significantly lower the risk of miscarriage during assisted reproduction cycles. It provides valuable insights for women and healthcare professionals seeking to enhance reproductive outcomes.
Does the research suggest any potential applications for future studies?
Yes, the research suggests that the results could inform future studies investigating the effects of nutritional interventions on human fertility. It highlights the need for further research into how dietary patterns can impact the outcomes of infertility treatments and human reproductive health.

Infertility prob, 15% people, wow! diet help? AHA diet, fish, grains, folic acid, 13-15% less miscarry. good study.
Healthy diet, big deal for fertility! AHA diet works. Need more research on diet and baby-making.
Heart-healthy food, less miscarry? Good news. But veggie diet not so good. Fish and meat miss. Need omega-3!
Interesting link between diet and pregnancy. AHA diet reduces miscarriage. Big research, good info for future studies!
study say, eat healthy heart diet, less risk miscarry! fish, grains, omega-3, folic acid good. big sample, good info.
