My naturopath gave me the following general dietary recommendations. I never did work out what was for fertility and what was just for good health.

I'm vegetarian (but do eat fish) so she told me I had to eat 3 cups of greens a day (I never quite got there but i did improve) and an egg everyday.

Cut back on cows milk and general dairy like cheese - I was drinking a cup of plain milk every morning and cheese everyday. Yoghurt was okay though.

Stop using margarine and swap to butter.

Eat two pieces of fruit a day. I wasn't eating any, but ended up eating one piece every day and sometimes 2.

I was also on bunch of herbs, vitamins etc.

Good luck!!!
