For the past 2-3 months I have been taking 1-2 tbsps of flaxseed daily (usually just one) so that I can get more omega 3's. I understand, however, that our bodies can't convert all the omegas from flax so I do take fish oil as well and incorporate a lot of fish in my diet. I've been eating mostly paleo for about 3 months now and I have noticed some positive changes but it's been hard as paleo has been the cause of some problems as well, namely my weight loss. I'm 5'6 and before I started I weighted 106 pounds, already underweight, but I have gone down to 98 pounds, emaciated. This change was gradual and because I had no scale, I didn't notice how much weight I lost until two weeks ago. Recently I have started incorporating more carbs and have been able to gain 2 pounds in the past two weeks. My biggest problem has been the loss of my period for 2 months now. I know that this can be(and probably is) attributed to my low weight and bodyfat percentage but I was wondering if the flax could also be a cause. I don't remember if I stopped before or after starting to take flax and I know that flax is a phytoestrogen so it can mess with hormones. I've heard of flax messing with other people's cycles but I was wondering if it can entirely stop reproductive function. It's not menopause since I'm only 18 so I was wondering if anyone had any more information on the detrimental effects of flax and if it could be harming my body.
I have PCOS which causes irregular periods to begin with. When I started low carb I thought I would have a daily flaxseed "muffin in a minute" to replace the bread I was no longer eating. Each muffin contained about 1/4 cup of ground flax. A few weeks after starting, I began spotting. Spotting turned into bleeding which got heavier and heavier and continued for EIGHT weeks. My doctor attributed it to menopause, but I knew that wasn't it. I was also anemic at that point.
I started doing my own research and found that heavy bleeding can be attributed to flax. I stopped the flax and within two days, the bleeding stopped. Perhaps it was coincidence, but I don't think so.
I do believe the phytoestrogens in flax are potent enough to have an effect. In me it was bleeding, but for you it may be interruption of your normal cycle. I would suggest stopping the flax (particularly since you are getting fish oil) and see what happens.
I still use flax but in true moderation, only in small amounts and not regularly.
NOW for something else: Getting down to 98 pounds is dangerous--as you seem to realize--in an of itself, and it is as likely responsible for the cessation of cycles as the flax--more so in fact. Your body is not going to let you reproduce when you are fighting for your life! In some circles, you would be hospitalized if you showed up at that weight. I hope you are at least under a doctor's care to rule out any other serious medical condition. You need to buy a scale and keep a close eye on your weight so that this does NOT happen again. You have your whole future in front of you, and you could cause serious and lifelong damage if you continue to lose weight. I suspect you know that, and I wish you the best in restoring your health by gaining and maintaining a healthy weight.
Check out my recent post here. If simply eating more healthy, substantial food (fish, eggs, beef, olive oil, etc) doesn't help you gain weight and get your period back, then you may have some sort of malabsorption issue. Perhaps look into probiotics, fermented food, GAPS protocol, etc.
Like you Natasha I also lost weight following the Paleo diet, and it has been hard to put it back on.
What has worked for me is eating more eggs and re-introducing whole meal pasta/bread/swet potatoe back into my diet.
Sure it's not strictly Paleo, but when you're working out 3-4 times a week I think your body is able to process complex carbs much more efficiently.
The weight is slowly coming back on now.
Basically, yes. They're a pretty weird foodstuff, the like of which our paleo ancestors wouldn't have had access to significant quantities of, since nuts/seeds are seasonal and flax seeds require a lot of processing in order to eat a significant quantity of them. This would be a good reason to not eat many of them, prima facie.
You don't need to get large amounts of omega 3. Really, you want a sufficient amount for basic functions as an essential fatty acid and then very little more, to balance out omega 6. You want low levels of PUFA in general, since they're easily oxidised. I would say you want no more than a couple of grams per day. On a 2000kcal diet, 2g o3 will place you on the Japanese line of this graph. http://2.bp.blogspot.com/_zULJExxrW54/ShrxAXIU4XI/AAAAAAAAAgw/t-gGvhBo_uI/s1600-h/Lands+HUFA.jpg
Since as you've noted ALA from flaxseed can't be converted in significant quantities, it would definitely be better to just limit yourself to EPA/DHA.
Yes: flax is a potent enough source of plant estrogen to disrupt your normal cycles and cause other side effects associated with fluctuating estrogen levels (i.e. acne, bloating, emotional disturbances, etc.). If you have any disorders that are hormone sensitive, use flax seed sparingly and with a good deal of caution. It can make conditions like poly-cystic ovarian syndrome and fibroids much worse.
Not all people react to flax similarly. The ability to metabolize the flax and use the estrogen varies from person to person. Some people simply don't have the intestinal flora or innate enzymes to efficiently break down the plant estrogen very well and those folks simply urinate/defecate out much of the phytoestrogen unused. Others have bodies that are masters at breaking down and absorbing plant estrogen and must be very cautious about flax consumption. Just as brown eyes aren't superior to blue, neither body type is better - we're all simply different.
I (unknowingly) fell into the latter group and happen to metabolize phytoestrogen from flax very well. I was eating 1 to 2 tablespoons of ground flax per day with my oatmeal in the mornings. I did this for about eight weeks, with no apparent side effects outside of a mysterious case of acne (I'm 37 and hadn't struggled with acne before). On week nine I went out of town for a three week vacation and left my flax at home. I'd finished my last normal (5 day) menstrual cycle just a few days prior to departure. In spite of that, I started bleeding 7 days after being off flax. The bleeding continued for two weeks. During that span of time I saw an internist, an OB/GYN, and had 3 pelvic exams and an ultrasound to rule out infections, endometriosis, fibroids, cancer, pregnancy, etc. The bleeding then ceased - only to pick up again 11 days later and continue for another 2 weeks. Long story short: the culprit was flax. It took me almost 3 months to stabilize.
My physician recommended that if I were determined to eat flax, that I do it sparingly and infrequently. I'm abiding by that guideline and have returned to my happy healthy self. Best of luck to everyone out there trying to figure out what's best for their own body. Hope this information benefits someone else!
