Reddit mentions of The Fertility Diet: Groundbreaking Research Reveals Natural Ways to Boost Ovulation and Improve Your Chances of Getting Pregnant

I'm pretty late to the game, but thought this book might interest you: https://www.amazon.com/Fertility-Diet-Groundbreaking-Research-Ovulation-ebook/dp/B0010QI2J4

It's based on good research, and I think it contains recipes, but there are caveats:

1. It's linked to higher fertility rates for women who have struggled to get pregnant because of irregular ovulation, so it's not necessarily helpful for every woman
   
   
2. It's based on a large scale correlational study, meaning that they had a lot of woman answer questions about their diet and then waited to see if women who ate in certain ways were more likely to get pregnant. So, the best they can say is like, "We have reason to believe these foods are related to higher fertility, and it seems causality is a likely explanation, but we can't definitely say it's causal." So, like, maybe women who want to be healthy tend to eat a lot more legumes and full-fat dairy than women who are not trying so hard to be healthy, and it's just easier to get pregnant when you're eating healthy. This might be especially true because the data is a bit old (the study began in the 70s), and I think that ideas about "healthy food" were a little more uniform back then than they are now, so people who were health conscious tended to have pretty similar diets.
