Here’s something important about PMS or PMDD (premenstrual dysphoric disorder): At least some of the time it’s caused or worsened by mast cell activation and histamine.
Histamine is an inflammatory compound as well as a neurotransmitter. That’s why histamine can cause both allergy-type symptoms such as hives and nasal congestion as well as mood symptoms such as anxiety. Histamine can also cause headaches, fatigue, brain fog, insomnia, and breast tenderness — all the typical symptoms of PMS.
If you follow my blog, you know how much I care about women and women’s health. I want women to be fully nourished and eat in a way that supports ovulation and hormones.
I am, therefore, concerned about any diet that seems to impair ovulation. That can include a low-carb or keto diet, which can stop ovulation and periods. That can also include an exclusively plant-based or vegan diet, which can stop ovulation, but more often seems to cause long cycles and progesterone deficiency.
If you’re vegan, I encourage you to keep reading and join the conversation in the comments. I particularly want to hear from anyone who has been vegan for at least a year. (And see below for a tally of the comments so far.)
