This “pro fertility diet” was developed by researchers, and includes a few key strategies from other studies and diets that are believed to help people with ovulatory concerns. For example, the diet suggests prioritizing eating whole grains, dairy, soy or plant-based protein, fish, and organic produce. It also encourages people to take folic acid, B12, and vitamin D supplements. “Researchers showed that the more likely people were sticking to these kind of dietary patterns, the more likely they were to have live births if they were undergoing assisted reproductive technology or fertility treatments,” Mallik says. But again, this is just one fraction of the population of people with fertility issues.
