According to a new observational research study, the Mediterranean diet may improve a woman’s fertility. The study, completed in Spain, drew a conclusion to the connection between the Mediterranean diet and fertility based on insulin response. The American or Western diet is packed with sugars and processed foods. So, in order for the body to digest and use these foods correctly, an increased amount of insulin is needed. When the body has too much insulin, the other hormones in the body, like reproductive hormones, are not released accurately.
The Mediterranean diet, which is loaded with fruits, vegetables, healthy fats/oils, and whole grains, helps to control blood glucose. By helping to control the body’s blood glucose, or insulin response, this can assist fertility and reproductive hormones maintain a healthy balance.
Researchers studied more than 500 women who reported having trouble getting pregnant. Another 1,600 women with at least one successful pregnancy ending in live birth were also included in the study as a control group. The research split the group into Western diet and Mediterranean diet categories. The women in the Western diet category showed no difference in fertility whether they followed a Western diet strictly or loosely. The Mediterranean diet group, however, showed a significant difference in fertility based on how closely women followed the diet.
In contrast, approximately 17% of women who followed the Mediterranean diet firmly reported problems becoming pregnant. When women followed the diet loosely, that number jumped to 26%.
So, you can see that nothing is absolutely proven with the diet and fertility… yet. Not all doctors are convinced about the connection. There isn’t enough information to show that this diet pattern can assist a woman at becoming pregnant.
Also found in a new research study, diets containing foods rich in monounsaturated fat, like green fruit, olive oil, peanuts, almonds, and cashews, could triple chances of women becoming pregnant via fertility treatment. Health professionals believe a diet similar to this could assist most women wanting to become pregnant naturally as well. In this study, it was clear that consuming a diet high in saturated fat, found in dairy and red meat, appeared to impair women’s fertility. Diets high in saturated fat have also been linked to lower sperm counts in men. The School of Public Health at Harvard looked at how the intakes of different types of fats affect success rates of IVF treatment in women mostly in their 30s. The study found the women who ate the most monounsaturated fat had up to 3x the chance of giving birth via IVF, compared to those who ate the least.
