Spend time hanging round different well being areas, and also you’ll undoubtedly come throughout seed biking. This in style protocol goals “steadiness ladies’s hormones” and assist with all kinds of points associated to hormones and the menstrual cycle. Proponents use seed biking for every thing from PMS signs, dysmenorrhea (painful menstruation), and irregular cycles to PCOS, infertility, ovarian cysts, and menopausal signs like scorching flashes and evening sweats.
Testimonials abound from ladies who credit score seed biking with altering their lives. No scarcity of holistic docs, naturopaths, dietitians, and bloggers market it as a useful device, or perhaps a miracle treatment, for girls. There are additionally loads of skeptics.
Whereas it’s nice to maintain an open thoughts, we additionally need interventions that really work. No one desires to throw invaluable money and time after cures that don’t do something or, worse, that trigger hurt. Whenever you dig into the claims, they appear somewhat too good to be true, however they aren’t. Let’s take a look at the proof.
What’s Seed Biking?
Seed biking is a program the place you eat sure seeds throughout totally different phases of the menstrual cycle. In line with proponents, in the event you diligently observe the protocol for a number of months, you possibly can anticipate to see enhancements in no matter signs or illness you’re hoping to deal with.
Seed biking appears to be like like this:
- Throughout the follicular part (first day of menses to ovulation), devour one tablespoon of flax seeds and one tablespoon of pumpkin seeds per day.
- Throughout the luteal part (day after ovulation to day earlier than menses), devour one tablespoon of sunflower seeds and one tablespoon of sesame seeds per day.
Don’t know if you ovulate? No drawback, you are able to do flax and pumpkin for the primary half of your cycle (roughly days 1 to 14) and sunflower and sesame within the second half (days 15 to twenty-eight, or nevertheless lengthy your cycle is). Ladies who don’t menstruate are suggested to make use of the moon cycle as a information. New moon to full moon corresponds to the follicular part, full moon to new moon is luteal.
For digestibility, it’s vital to grind the flax seeds and sesame seeds. Often, seed cyclers grind all of the seeds utilizing a spice mill or espresso grinder, or you should purchase premade seed blends. Sprinkle the bottom seeds over yogurt or salads, combine it into smoothies or soups, or simply make a sludgy shot of seed water.
How Does Seed Biking (Supposedly) Work?
Seed biking advocates declare that it balances your hormones, that means that intercourse hormones (largely estrogen and progesterone) are at appropriate levels at totally different factors of the menstrual cycle. When intercourse hormones plummet throughout menopause, seed biking allegedly helps mitigate these results, too. Supposedly, this works for a variety of causes.
At the beginning, seeds comprise compounds referred to as lignan precursors. Whenever you eat them, micro organism within the intestine metabolize them to create lignans. Lignans are phytoestrogens, just like the isoflavones in soy. As a result of their chemical buildings are much like estrogens the physique produces naturally, lignans can bind to estrogen receptors and mimic the results of estrogen. Proponents say that lignans assist create an excellent steadiness of estrogen and progesterone within the physique, boosting estrogen when it’s too low and binding it to facilitate detoxing when it’s too excessive. (We’ll return to this declare later.)
Different alleged advantages come from nutritional vitamins and minerals within the seeds. Particularly:
- Zinc, largely from pumpkin seeds and sesame seeds, is supposed to prime the physique to supply progesterone.
- Vitamin E in sunflower seeds is likewise meant to encourage progesterone synthesis.
- Selenium from sunflower seeds is meant to assist clear (or “detox”) the physique of extra estrogen.
However does it really work like that?
That’s the million-dollar query.
As discerning well being customers, we have to perceive {that a} idea will be “mechanistically believable,” which implies that if you clarify why it may work, it completely is sensible. Nevertheless, it nonetheless won’t be true. In science, hypotheses often begin with concepts which can be mechanistically believable, however then these hypotheses should be examined. Some hypotheses that appear fully legitimate and smart don’t bear out below scrutiny. That’s why empirical analysis is significant.
Seed biking is mechanistically believable. Lignans are phytoestrogens, and flax and sesame seeds are each vital dietary sources of lignans. Zinc is vital for reproductive well being. Selenium does promote glutathione synthesis. Glutathione is a crucial antioxidant and an vital part of the physique’s pure detoxing system. The physique does excrete extra estrogen.
So you possibly can see the place the thought for this protocol might need come from. The issue is, there actually isn’t any strong proof that seed biking really does what it purports to do.
Sure, lignans are phytoestrogens, however scientists are nonetheless working to know how, precisely, lignans have an effect on intercourse hormone ranges. They are often both estrogenic or anti-estrogenic, however it’s not but clear how and after they exert totally different results. There’s positively no concrete proof that they work like sensible medication, rising or lowering estrogen on an as-needed foundation to create optimum hormone steadiness.
Proponents of seed biking rely closely on one small research from 1993 that requested 18 ladies to devour flax seeds for 3 months. On this research, flax seed consumption led to fewer anovulatory menstrual cycles (cycles the place an egg just isn’t launched as anticipated) and a extra favorable progesterone-to-estradiol ratio throughout the luteal part. Nevertheless, a lot of the results on intercourse hormone ranges weren’t vital. Tellingly, this research has by no means been replicated, that means the findings couldn’t be reproduced with extra highly effective research or different researchers didn’t assume this was vital sufficient to observe up on.
Total, there may be solely the scantest proof that lignans immediately have an effect on intercourse hormone ranges. Loads of research discover that they don’t. Furthermore, keep in mind that lignans are created within the intestine. Not everybody has the microbes wanted to transform excessive ranges of lignans. So even when seed biking does work as proponents declare, we’d anticipate that some folks would profit way more than others.
Zinc, vitamin E, and selenium are undoubtedly vital for total well being and reproductive well being particularly. Nevertheless, there’s nonetheless quite a bit to study how supplementing impacts the outcomes we’re fascinated by right here. For instance, a 2020 overview entitled “The Function of Zinc in Chosen Feminine Reproductive System Problems” concluded that zinc dietary supplements could assist with PCOS and dysmenorrhea, however there’s a dearth of proof in relation to points like endometriosis and menopause. Equally, a 2016 overview of antioxidants concluded, “Given the complexities of hepatic processing and the contribution of food plan and lipoprotein metabolism, extra analysis is required to additional discover the potential relations and mechanisms between specific vitamin E concentrations and reproductive outcomes.”
In brief, we nonetheless have a lot to study all these processes. Moreover, the seed biking speculation depends on mechanistic pathways (A resulting in B) that aren’t at present well-supported by knowledge.
Seed Biking Has By no means Actually Been Put to the (Empirical) Check
The underside line is that this protocol has by no means been rigorously examined. I couldn’t discover any research the place individuals adopted this actual routine and scientists in contrast their outcomes to a management group. Even when the proof for all of the mechanistic pathways was sturdy—and it isn’t—your complete protocol would nonetheless have to be put to the take a look at.
Presently, all of the proof is anecdotal. To be clear, I’m not discounting the experiences from ladies who really feel like seed biking labored for them. Anecdotes will be informative, however we are able to’t rely solely on them. They depart too many questions unanswered.
- For individuals who have success with seed biking, is it as a result of lignans, nutritional vitamins, minerals, and fatty acids are optimizing hormone steadiness? Possibly. Or possibly it’s on account of different compounds or totally different mechanisms like decreasing irritation.
- May or not it’s a placebo impact? Maybe (and also you may be pleased with that so long as you get the outcomes you need).
- Is there a greater approach to make use of seeds and/or the compounds they comprise to realize the identical targets? We don’t know.
These are all questions that well-designed, well-controlled laboratory research may reply. Research that we don’t at present have.
The Verdict: Is Seed Biking Value Making an attempt?
On the one hand, I’m tempted to say it will possibly’t damage, would possibly assist. Seeds offer lots of other benefits. They’re good sources of vitamins like B nutritional vitamins, magnesium, manganese, and copper, in addition to fiber and the aforementioned vitamin E, zinc, selenium, and fatty acids. Lignans have identified antioxidant, anti-inflammatory, and anti-cancer properties. Flax and sesame seeds appear to have cardioprotective results. Pumpkin seeds can enhance blood glucose ranges.
Alternatively, many ladies flip to issues like seed biking after standard docs have been unable, and even unwilling, to assist them. PCOS and endometriosis victims notoriously battle to get correctly identified and handled. We don’t have nice options for menopausal women dealing with common symptoms like scorching flashes, evening sweats, and despair. These ladies have been let down so many instances. I’m subsequently reluctant to offer a thumbs as much as one thing that has no strong proof behind it. There’s a danger, too, of delaying or avoiding medical therapy in favor of other therapies that in the end aren’t what you want.
Though the dangers of seed biking appear low, you have to be conscious of some issues:
- Seeds are excessive in phytates and will be allergenic, so that they don’t work for everybody.
- They’re additionally excessive in fiber, resulting in gastrointestinal points for some of us.
- Seeds aren’t allowed throughout the elimination part of the AIP plan.
- In case your physician has suggested you to restrict your consumption of phytoestrogens, be sure to speak to them first.
Lastly, if hormone well being is your objective, step one is to be sure to’re nailing the big-ticket gadgets: diet, sleep, stress administration, and wholesome motion.
So what’s YOUR verdict? Are you curious about seed biking or not a lot? Have you ever tried it already?
