Seed cycling. Ever tried it?
I first became aware of the idea that diet affects your menstrual cycle from the book WomanCode by Alisa Vitti, which (among other wonderful, helpful things) promotes eating certain foods during certain times of your cycle to improve hormonal health. Sign me up.
One simple application of this concept is seed cycling, which is essentially adding specific seeds to your diet at various times in your cycle to help optimize hormonal health.
