Today’s post may feel a bit out there, but that’s why it’s also nestled under my “miscellaneous” category. So, having absolved myself of all guilt for anyone who misinterprets this post as hard fact, I begin.
I recently saw the term ‘seed cycling’ used on social media and became intrigued as to one, what it meant, and two, what benefit it had (if any).
A quick Google search led me to both answers. Seed cycling is somewhat literally what it sounds like (although my first guess as it was 4am as I wrote this, involved interpreting cycling as bicycling). You cycle between seeds in your diet, consuming specific ones at specific types during your menstrual cycle (and supposedly it can be use for peri-menopausal and post-menopausal women as well).
Anyway, the theory is that a menstrual cycle is most naturally working if it is within the 28-day cycle, and anything else indicates some sort of imbalance of estrogen. The seeds chosen during the two phases of the menstrual cycle (when estrogen is decreasing and when it is increasing) are chosen specifically to help balance out the estrogen in each phase to allow the person to resume the natural cycle duration.
At this point you may be wondering why am I posting about this on my eczema blog? Well, you may recall from my post on pregnancy, that one of the factors believed to provoke eczema in pregnant women is the surge of estrogen. So my hypothesis is that if one’s cycle is off, and they experience larger ranges of estrogen surges during phases of their cycle, perhaps that would increase the intensity of an eczema flare.
Here’s a quick overview about the menstrual cycle (I previously worked as a women’s health consultant, so I both enjoy this kind of knowledge and could use the refresher myself). We have 4 phases: menstruation, the follicular phase, ovulation, and then the luteal phase.
- MENSTRUATION – This is the phase in which the lining of the uterus (or the endometrium), which has thickened over the month, comes off and there is bleeding from the vagina.
- FOLLICULAR PHASE – This phase starts on the first day of menstruation. The pituitary glands, triggered by the hypothalamus, release follicle stimulating hormone (FSH), and FSH in turn causes the ovaries to release a few follicles, each of which has an egg. One of these follicles’ eggs will start to mature, while the others die (around day 10). The uterine lining starts to thicken during this phase too due to follicular stimulation. The follicular growth also causes a surge in estrogen, which the body compensates for by the hypothalamus releasing gonadotrophin-releasing hormone (GnRH), which gets the pituitary gland to release lutenizing hormome (LH) and FSH.
- OVULATION – During this phase, the high levels of LH triggers the release of the mature egg from the ovaries in two days. The egg is propelled by little hair-like structures through the fallopian tube into the uterus. Once there, it can survive for only about 24 hours. During this process, the egg has “hatched” out of the follicle, and the follicular remnant that gets dragged along outside the egg becomes the corpus luteum. The corpus luteum releases progesterone and a little estrogen, a mixture that helps keep the uterine lining thickened.
- LUTEAL PHASE – During this phase the corpus luteum releases progesterone and a little estrogen, a mixture that helps keep the uterine lining thickened. When no pregnancy occurs, the corpus luteum falls off and dies (around day 22), causing a drop in progesterone. The progesterone drop triggers the uterine lining to fall off (aka menstruation), hence the cycle repeats.
So how does one do this seed cycling, you ask? Well, during the follicular phase (day 1 when you start to bleed to day 14) you take a daily dose of 1 tablespoon of ground flax/pumpkin/chia seeds. From days 15-28 you take a daily dose of tablespoon of ground sunflower/sesame seeds. That’s all there is to it.
But why is this supposed to work? I couldn’t find any rigorous studies on seed cycling, but came upon a blog post written by a naturopathic doctor (Dr. Lindsey Jesswein). She explains that the seed hulls have chemicals called lignans, which help “modulate hormone pathways”, and the seed oils (made of omega fatty acids) help “provide the building blocks for steroid hormone synthesis”. Jesswein then describes each seed (minus chia) a bit more by what they provide:
- Flax – vitamin B, manganese, and magnesium
- Pumpkin – iron, magnesium phosphorous, zinc
- Sesame – vitamin E, vitamin B1, manganese, irin, magnesium, copper, sesamin
- Sunflower – vitmin E, linoleic acid, magnesium, potassium, zinc, calcium
The Herbal Academy (which was how I came to Dr. Jesswein blog post) goes into a bit more detail about the various benefits of each of these seeds and provided studies, but noted that the information was on individual seeds and not their impact with seed cycling.
A few of the studies they included (and some additional ones I found) found that:
- flax may help to lengthen the luteal phase and reduce missed periods,
- pumpkin may improve HDL cholesterol levels and reduce hot flashes, joint pain and headaches
- pumpkin and sunflower may aid in reducing postmenopausal breast cancer risk
- sesame seeds, according to Ayurvedic philosophies, are supposed to be able to improve “scanty menstruation”
- a maternal diet of flaxseed versus casein results in lower body fat mass and visceral fat mass, cholesterol, and triglycerides for the offspring when weaned. Note I have no idea what species they were studying as I could only access the abstract, but I’m assuming they tested mice
Overall the evidence of large changes for the menstrual cycle is not huge, but at the same time, it generally doesn’t hurt to consume seeds in one’s diet so it may be worth trying if you want to play around with your nutrition (though always seek advice from a medical professional first, especially if you have a specific condition you are trying to treat!).
I’m curious to apply seed to myself so I might give it a trial for a few months and report back. Maybe. I’m also incredibly fickle, so probably not. I generally eat flax anyway with breakfast and the like, but I wouldn’t be able to notice if there were any changes because I’m still breastfeeding and thus not getting my period anyway.
Also I do understand that engaging in many different eczema projects simultaneously results in confounding the data as to which project individually helps my eczema, but it is my belief that eczema cannot be managed by just one miracle solution (though diet is a huge one) and so enacting multiple positive changes and approaches, so long as they are sustainable to myself lifestyle, I view as being the most maximally beneficial.
