A lot of people ask me how I’ve got from total histamine intolerance breakdown to where I am. While I do believe my recovery is still a work in progress, I thought I’d share how a combination of militant food planning, 30 minutes of inflammation fighting yoga and daily chanting (OM!) have allowed me to reach a far better place than I have ever been.
Thanks to my years studying nutrition (unofficially) through the teachings of Drs Fuhrman, Weil, Oz and others, I was well aware my new low histamine diet had the potential to be unhealthy and counter-productive, if applied strictly, and blindly.
To acknowledge something and to implement it are two very different things. It took me a while to get my sea legs. I floundered around for some time, terrified to add new foods or even entertain the idea of being proactive in my recovery. But I knew I had to take action when I began to approach meal time with fear and hatred, focusing on the food rather than the state of my broken body and mind. I was now eating the same five foods every single day, usually in large amounts, not understanding why I wasn’t “recovering”.

WHO AM I?
YASMINA YKELENSTAM – THE LOW HISTAMINE CHEF
The fridge and fields are my medicine cabinet. I’ve managed to withdraw from all pharmaceuticals including: anti-histamines, anti-anxiety meds, antidepressants, migraine, nausea, and dizziness meds. I’m now the happiest and healthiest I’ve ever been. I’ve learned to harness the positives that high histamine bestows (appetite suppression, higher metabolism, energy) and make them work for me!
Who the hell am I to give dietary advice? My cookbooks reflect the incredible amount of research into histamine and other biogenic amines in food that I’ve obsessively collected over the last two years since my histamine intolerance diagnosis. As a former journalist with over 10 years research and international news production experience for 60 Minutes, CNN and the BBC, I know how important the facts are. Not only do I back up each claim on my site with numerous studies, I’ve even used myself as a guinea pig, taking myself from washed up medical mystery to successful 21st century businesswoman.
I suffered daily migraines for many years. At some point I finally came to the conclusion that my headaches, which made me bang my head against the wall on occasion, had something to do with my diet. I was vindicated by the person who diagnosed me with histamine intolerance in London, and now by the growing number of studies clearly spelling out the allergy/histamine migraine link.
I cannot even begin to properly thank my lucky stars for curing me of this blight. I was about six weeks into the low histamine diet when I was able to trash the 600mg ibuprofen that I had been scarfing daily by the handful for most of my adult life. Not to mention the migraine injections. Youch! You truly haven’t experienced hell till you’ve had a constant migraine for six months.
Interestingly, in Spain (and France), it’s commonly acknowledged that migraines are caused by a lack of the histamine-lowering enzyme diamine oxidase (DAO). Seems that the US and UK are way behind the curve on this one.
But histamine can also cause migraine in “healthy” people:
Headache can be induced dose-dependently by histamine in healthy persons as well as in patients with migraine (53, 61). Histamine-induced headache is a vascular headache caused mainly by nitrate monoxide (62). Histamine releases endothelial nitrate monoxide upon stimulation of H1R, which is also expressed in the large intracranial arteries (63). In migraine patients, plasma histamine concentrations have been shown to be elevated both during headache attacks and during symptom-free periods. An increase in the number of brain mast cells is associated with pathologic conditions such as migraine, cluster headache, and multiple sclerosis (64). Many migraine patients have histamine intolerance evidenced by reduced DAO activity, triggering of headache by food rich in histamine (eg, long-ripened cheese or wine), and the alleviation of headache (ie, disappearance of symptoms) under a histamine-free diet (57, 65) and therapy with antihistamines (66). Maintz and Novak.
Meanwhile, for those of us presenting with histamine intolerance, histaminosis, mastocytosis or mast cell disorders…
This study colludes that: “Thus, the avoidance of allergic conditions in migraine patients may be a simple, helpful way for prophylaxis or their treatment.”
Although migraine affects about 15% of population and many studies have been performed to find the mechanism and a successful management, the physiopathology of migraine is still largely unknown. The possibility of an immunoglobulin E (IgE)-mediated allergic mechanism and the role of histamine remain controversial. The aim of the present study was to evaluate serum total IgE and histamine levels in migraine patients and the influence of allergy on them. Seventy patients (18-58 years) with migraine without aura were divided into two groups according to their history of allergy (60% with and 40% without allergy). Serum samples were collected during fasting without allowing any premedication during the two periods of attack and remission. There was a control group containing 45 healthy volunteers. Serum total IgE and histamine levels were measured by enzyme-linked immunosorbent assay and fluorimetric methods, respectively. Mean and standard errors of serum histamine (ng/ml) and total IgE (IU/ml) levels were found in the control group to be 48.16 +/- 2.70 and 38.31 +/- 3.20, in the migraine with allergy group 159.11 +/- 4.60 and 303.30 +/- 42.50 and in the migraine without allergy group 105.01 +/- 8.50 and 79.07 +/- 2.70, respectively. Total IgE levels in migraine with allergy group were found to be significantly (P < 0.0001) above that in the control and another group, suggesting an influence of an IgE-mediated mechanism on migraine. Although the plasma histamine levels, which were significantly elevated (P < 0.0001) in patients with migraine, both during headache and symptom-free periods, when compared with the control group, indicate that there is an increased susceptibility to histamine in allergic conditions, this molecule has also an unrelated role in migraine. The relationship between allergy and migraine can be based, in part, on an IgE-mediated mechanism, and histamine release plays an important role. Thus, the avoidance of allergic conditions in migraine patients may be a simple, helpful way for prophylaxis or their treatment.

Tired of your man attributing every nuance of behavior to your menstrual cycle? Well, he could have a point, but you’d die before admitting it (yup that’s me I’m talking about).
Well here’s a little nugget to wave under his nose. It’s not the menstrual cycle, it’s the histamine stupid!
Japanese researchers have (re)confirmed that the histamine lowering diamine oxidase enzyme (DAO) is influenced by the menstrual cycle.
“Serum DAO levels were influenced by the menstrual cycle. Furthermore, our findings suggest that serum DAO levels should be interpreted cautiously in premenopausal women.”
This could explain why an allergy to food or environment seems to affect you differently each time, depending on where you are in your cycle and how much histamine-lowering diamine oxidase is available to you.
We know from Maintz and Novak’s seminal histamine study, that DAO is at its highest during pregnancy (500% – 1000% higher) so it’s a not unreasonable to conclude that lower hormones = lower diamine oxidase? BUT, that’s not right…
“estrogen can influence histamine action. A significant increase in weal and flare size in response to histamine has been observed to correspond to ovulation and peak estrogen concentrations (118).” Maintz and Novak.
This would seem to point to diamine oxidase being lower during ovulation – though we’re now not taking the potential involvement of monoamine oxidase and HNMT (the other enzymes involved in histamine metabolism) into account. Phew, I’ve confused myself. What is certain is that high histamine mimics the symptoms of anxiety so if you have a histamine-related disorder, certain times of the month are going to be tougher than others.
So, where does this leave your average diamine oxidase impaired lass?
In last week’s post “Histamine’s upside: I lost 35kgs in 6 months” I mentioned the role of histamine in appetite suppression. I recently had a conversation with a friend whose family member suffers from anorexia nervosa. I felt compelled to share that in my teens I too was thought to be anorexic. Food was hurting me so badly that I was starving myself to make it stop. It was more than just a physical reaction, because as we know, histamine is a neurotransmitter and as such affects mood. Food made me crazy, depressed, anxious and manic but I had no clue what was causing it all, despite my raging allergy symptoms.I’ve spent the last few days doing some more research into what’s behind my suddenly stable weight these last two years:H1 receptor antagonists like loratidine (claritin) and cetirizine (zyrtec) make you fat. It’s just a fact. It’s in the medical inserts of both and my own personal hellish experience on them confirms it. At my worst, when I was taking one and a half to two pills daily, I became obsessive about food – to the point of dreaming about eating. I would get up several times a night to rummage through the fridge and spend almost the entire day absolutely ravenous. I would graze all day long. The most incredible benefit of having stopped them is the relief from my food fantasies. I can now easily go half a day without once thinking about food. Is that abnormal? Seems I have H3 receptor stimulation to thank for it. Studies show that H3 receptor agonists (the opposite of antagonists like Claritin and Zyrtec) suppress appetite.
The H3 receptor is a pre-synaptic autoreceptor that inhibits the synthesis and release of histamine, and a heteroreceptor that inhibits other neurotransmitters such as serotonin (5-HT), noradrenaline (NA) and acetylcholine (ACh), which are also implicated in the regulation of food intake. Thus, the H3 receptor is in a prime position to regulate food intake, both through its control of histamine and its influence on other feeding pathways.Study
Translated into English: as a neurotransmitter, histamine affects the brain chemicals that control hunger!
Not just that, but the studies go on to say that histamine’s H3 receptor plays a part in how our body burns fat and what temperature your body runs at. I know from experience that my body runs very very hot when I’m in histamine overload. Interestingly I did some research into a diet pill I looked into in my teens – it worked by raising your body temperature.
Nowadays I don’t take any antihistamines, choosing instead to control my histamine level through diet (check out my low fat high nutrient low histamine DAO Support Cookbook) and a great quercetin supplement called Neuroprotek.
Next step would be finding out if certain foods affect just one of the histamine receptors, H3 in particular, in order to lose weight. Don’t worry, I’m on the case. Sign up to my newsletter for more info on this subject and others.
Not only is Holy Basil tasty in just about any Thai or Vietnamese dish – turns out it’s an anti-inflammatory, anti-histamine herb that’s as effective as Ranitidine/Zantac at treating H2 (histamine) induced ulcers, preventing mast cell degranulation and anaphylactic shock. How do’you like them apples?
I like Holy Basil a lot better than them apples…but just to clear up any potential confusion, Holy Basil is also known as Sweet Thai Basil or by it’s proper names: Ocimum tenuiflorum and Ocimum sanctum. (source: Wikipedia)
Holy Basil’s activity as an anti-histamine has been found to affect histamine’s H2 receptor, great news for those with histamine intolerance/histaminosis/mastocytosis/mast cell activation disorders with gastrointestinal complaints. I’d be interested to know if it’s anti-inflammatory effects are in part due to it’s high Vitamin K content. Don’t forget that Vitamin K (as I mentioned in this post), is a potent anti-inflammatory, is found in many foods like cauliflower, which is also high in Vitamin C.
“Basophils, mast cells, and their preformed de novo synthesized mediators, play a pivotal role in the pathogenesis of allergic disorders. These molecules are potent vasoactive and bronchoconstrictor agents and they modulate local immune responses and inflammatory cell infiltration (17-18).Immunoglobulin E (IgE)-mediated mast-cell stimulation is an important initial event in the development of type I allergic reactions such as asthma and atopic disorders. Clinical studies have found a close association between asthma and serum IgE levels, as well as IgE-dependent skin test reactivity to allergens. Antigen challenge, in sensitized animals, results in the degranulation of mast cells, which is an important feature of anaphylaxis. O. sanctum ethanolic extract showed marked protection against the mast cell degranulation following antigen challenge in sensitized animals. Mast cell stabilizing activity of extract may be attributed to the presence of anti-inflammatory mediator release, which is known for their mast cell stabilizing potential against antigen-antibody reaction and/or due to the suppression of IgE antibody production, which is responsible for degranulation mast cells. This antianaphylactic and antihistaminic effect may be due to the stabilization of the mast cell membrane, suppression of IgE, and inhibition of pathological effects induced by the release of inflammatory mediators in test extract treated animals.
Experimental results indicated the potent benefits of O. sanctum in the treatment of asthma and related conditions. The findings from various studies reveal that the antihistaminic and antianaphylactic activity of extract which is mainly due to its mast cell stabilizing potential, suppression of IgE, and inhibition of release of inflammatory mediators. Thus use of O. sanctum leaves proved the strong rationale behind the mentioned therapeutic activities [1].”
Holy Basil is as effective as Ranitidine/Zantac at treating H2 receptor induced GI complaints
“This study was conducted with the aim of comparing the efficacy of ocimum sanctum against gastric and duodenal ulcers. The hydralcoholic extract of the plant exhibited significant ulcer protective effect against gastric ulcers in pyloric ligated rats as well as against duodenal ulcers in histamine treated guinea pigs. In both these models of peptic ulcer, significant ulcer protective effects were observed with 100 mg/kg and 200 mg/kg of ocimum sanctum, which were comparable. These effects were also comparable with ranitidine which was used as the standard drug for comparison in both the models. The antiulcer activity of ocimum sanctum could be due to its antisecretory, anticholinergic or antihistaminergic properties. In view of this therapeutic potential, more studies are required to establish ocimum sanctum as a standard drug for peptic ulcer [2].”
They’re using high amounts of Holy Basil in the studies.What do you think? Would you consider adding Holy Basil to your diet as an anti-inflammatory or histamine blocker to help treat your histamine intolerance, histaminosis, mastocytosis or mast cell activation?
New studies show that aerobic exercise raises histamine levels. This isn’t news to me. When playing squash I have to take time outs to scratch myself silly and wait for the room to stop spinning. My man, now used to such bizarre-isms, plays against the wall for a while till it calms down again. I looked a lot crazier, to a much larger crowd, during our recent trapezing class! I’m sure I can thank adrenaline for that…What really interested me in this particular study is that they determined resistance training (weights/yoga) doesn’t raise histamine levels. They highlight how histamine released by aerobic exercise causes significant vasodilation (the widening of blood vessels in the body).This study ties in nicely with last week’s post about histamine being a vasoactive amine that can increase or decrease heart rate and induce anxiety-mimicking symptoms.
*Resistance training is any exercise that causes the muscles to contract against an external resistance with the expectation of increases in strength, tone, mass, and/or endurance. The external resistance can be dumbbells, rubber exercise tubing, your own body weight, bricks, bottles of water, or any other object that causes the muscles to contract. http://www.emedicinehealth.com/strength_training/article_em.htm
Interestingly, I meeting quite a few people who are being prescribed anti-histamines by their docs to deal with asthma/wheezing, abnormally high heart rate and passing out while exercising. Wouldn’t it be simpler to go on a low histamine diet? Probably not, but it would yield better (healthier) results!
What does this mean for your work out routine?
Aerobic exercise, like my current favorites kickboxing and squash, can significantly raise histamine levels in the body. The upside (because in my world there always is one) is that people pay good money for pharmaceutical vasodilators to lower their blood pressure. The downside (other than the spike in histamine for those of us with histaminosis/histamine intolerance), is the migraines that accompany vasodilation. I often get migraine like headaches if it’s too hot in yoga class.
Does this mean I shouldn’t exercise?
I’m asked this a lot, usually by life long couch potatoes!
What I take from this study is that it might be a good idea, if you’re suffering from histaminosis/histamine intolerance, to explore “non dynamic” exercise like weight training, or my perennial favourite, yoga. Speaking of which, did you know that one of the many studies on yoga showed that females who practiced yoga regularly had 41% lower stress markers than non-yogis? And significantly lower inflammation! Given that inflammation (caused by high histamine) is a huge concern to those of us with histaminosis/histamine intolerance, it’s food for thought the next time you’re crashed out on the sofa telling yourself that exercise is bad (while contemplating another root around the fridge).
So what’s a histamine-challenged gal to do?
We’ve all been there, but there’s really no time like the present for a full body/mind make over. Try waking up tomorrow and investing in a yoga mat and a $15 subscription to Yogaglo online classes. I promise you won’t regret it.

Make-up allergies got you down? Have you considered that your beloved cosmetics are causing your histamine intolerance/chemical sensitivity/mastocytosis to flare up? If you’re on a low histamine diet but still suffering from make-up allergies, rashes and migraines, don’t despair, just bin the histamine raising dirty cosmetics! I did…
As the head of a successful digital agency in London, meeting and pitching clients is a daily requirement, and looking good is a must. It took me a long time to accept that cosmetics played a role in my declining health. But once I did, I worked hard to get out of the toxic mindset and figure out alternatives. In this ebook you’ll find the tips, tricks and coping strategies I’ve discovered, developed and employed these last two years, that helped me stand out from the crowd in one of the world’s most fashionable cities.
This book lists my favourite non-allergenic make-up, beauty, cleansing and styling products, home-made beauty product recipes and my personal beauty & make-up routine, as well as featuring a number of natural cosmetic video make-over tutorials and tips on everything from the perfect updo to how to have “the talk” with your hairdresser. You’ll find pages of resources and information on the biggest scams the make-up industry has perpetrated: hypoallergenic make up, organic labeling, carcinogenic ingredients and the hypocrisy of the pink ribbon campaigns.

I find it a little bizarre that not many out there are talking about the impact of cosmetics. Even when following a low histamine and tyramine diet to the letter (almost impossible but can be done for short periods) I still suffered symptom flare ups. My attitude at the time was: “hey, I’m suffering so I may as well pig out”. Wrong. Oh so very wrong.
Then I read this great book ‘No More Dirty Looks’. It got me thinking. If 60% of what we put onto our bodies is absorbed into our bloodstream (I still can’t find the science behind this claim),then why aren’t I concerned about what it could be doing to my histamine, tyramine or other amine levels?
FEB 2016 UPDATE: More importantly, research soon revealed that chemicals and additives commonly found in most cosmetics and bath products (even the supposedly natural/organic ones) have been shown to trigger histamine release, mast cell activation and cause other immune and endocrine dysfunction. Thankfully I’m now ok with most truly organic and raw beauty products (like the RMS beauty product pictured above), as long as they’re not heavily perfumed.
Here’s a few steps to detox your beauty routine…there’s a video where I share my favourite products in a little beauty make over.

5. Embrace natural brands.
Rose Marie Swift (RMS Beauty) is my hero! A trailblazing make up artist to the world’s supermodels (including Giselle Bundchen) who sufferers from chemical sensitivity. Her make up has 4-6 ingredients, mostly raw organic. They double up as moisturiser and make up. Does not raise my histamine or drive my immune system into a frenzy. I do have to stick to the light/nude colours which I love anyway. Reds (carmine) make my lips and eyes swell horribly. I also love my latest discovery Mineral Fusion for eyeliner and Hemp Organics for lipstick. You can find both of those brands at any Whole Foods in the States but not in the UK.
Dr. Oz calls inflammation an “invisible civil war raging in your body. Undetected it can cause heart attacks, stroke and cancer.” According to him, the problem begins when inflammation does not resolve following its role in healing an injury, causing your immune system to go haywire, turning your best friend into your worst enemy. This ties in to all my reading of this last year. Yes, inflammation is a serious concern when it unnecessarily stokes the immune system into over reacting to everything. Inflammation isn’t just dangerous to those of us with inflammation-induding histamine related disorders like histamine intolerance, histaminosis, mastocytosis and mast cell activation, it’s relevant to anyone with an interest in minimising their cancer, stroke and heart attack risk.
PRE-ECLAMPSIA – excessive maternal inflammatory response to pregnancy…(here’s a study on histamine in pregnancy)
And that’s where the low histamine diet comes in, at least for me. Histamine causes inflammation. Controlling its intake, especially when already dealing with a histamine-related issue, is a good first step, as is adding more anti-inflammatory foods to the diet. A word of caution here: just because something is anti-inflammatory doesn’t mean that you might not have a histamine reaction to it. We’re talking a straight up classic histamine/IgE mediate allergy or food intolerance here.
So, now you’re aware of why you need to be fighting inflammation, but what’s the best way to do it? I take a three pronged approach: diet (check out my low histamine cookbooks for recipes), supplements and lifestyle.
Vitamin K status, as measured by plasma phylloquinone and phylloquinone intake, was significantly inversely associated with the overall inflammation index, which represented the sum of the normalized deviates of the individual markers. Secondary analyses of the individual markers demonstrated significant (p<0.01) associations with 5 of the 14 markers. A two-fold higher plasma phylloquinone concentration was associated with 15 percent lower CD40 ligand, three percent lower intracellular adhesion molecule-1, eight percent lower interleukin-6, four percent lower serum osteoprotegerin, and four percent lower tumor necrosis factor receptor-2 concentrations in multivariable-adjusted analyses. Usual dietary phylloquinone intake was also significantly (p=0.01) inversely associated with C-reactive protein, fibrinogen, interleukin-6, lipoprotein phospholipase A2 mass, myeloperoxidase, osteoprotegerin, and urinary isoprostanes.
Histamine release inhibitors in watercress (Nasturtium officinale) were isolated using a monitoring system with antigen-stimulated RBL-2H3 cells. Of the 15 compounds isolated, flavonols and megastigmanes significantly inhibited histamine release. Two flavonols, 3-O-sophorosides of rhamnetin and rhamnazin, were new compounds. To investigate the inhibitory mechanism, the effects of rhamnetin, rhamnetin 3-O-sophoroside and an isolated megastigmane glucoside on the increase in the intracellular free calcium concentration were examined at a concentration providing 60% inhibition of histamine release. The results suggest that these compounds did not affect the calcium influx at that concentration. The structure-activity relationships of the megastigmanes on histamine release were also investigated.
We examined the effect of a crude hot-water extract (HW) of quince (Cydonia oblonga Miller) fruit on type I allergy in vivo and in vitro. The oral administration of the quince HW-added diet to NC/Nga mice for 63 d showed a significant decrease in the development of atopic dermatitis-like skin lesions under conventional conditions. The concentration of IgE in the serum collected from mice fed with quince HW was also lowered in a dose-dependent manner. Moreover, we found that quince HW inhibited the release of beta-hexosaminidase from rat basophilic leukemia cell line RBL-2H3 after a 24-h treatment. The quince HW fraction of less than 3 kDa reduced the mRNA expression of the high-affinity IgE receptor (FcepsilonRI) gamma subunit. These results suggest that quince HW had an inhibitory effect on type I allergy by suppressing IgE production and IgE-mediated degranulation.
The human body is made of some 250 different cell types. From them, only a small subset of cell types is able to produce histamine. They include some neurons, enterochromaffin-like cells, gastrin-containing cells, mast cells, basophils, and monocytes/macrophages, among others. In spite of the reduced number of these histamine-producing cell types, they are involved in very different physiological processes. Their deregulation is related with many highly prevalent, as well as emergent and rare diseases, mainly those described as inflammation-dependent pathologies, including mastocytosis, basophilic leukemia, gastric ulcer, Crohn disease, and other inflammatory bowel diseases. Furthermore, oncogenic transformation switches some non-histamine-producing cells to a histamine producing phenotype. This is the case of melanoma, small cell lung carcinoma, and several types of neuroendocrine tumors. The bioactive compound epigallocatechin-3-gallate (EGCG), a major component of green tea, has been shown to target histamine-producing cells producing great alterations in their behavior, with relevant effects on their proliferative potential, as well as their adhesion, migration, and invasion potentials. In fact, EGCG has been shown to have potent anti-inflammatory, anti-tumoral, and anti-angiogenic effects and to be a potent inhibitor of the histamine-producing enzyme, histidine decarboxylase. Herein, we review the many specific effects of EGCG on concrete molecular targets of histamine-producing cells and discuss the relevance of these data to support the potential therapeutic interest of this compound to treat inflammation-dependent diseases.
Ethanolic extract of fruits of Coriandrum sativum, leaves of Datura stramonium and Azadirachta indica showed a significant (p<0.01) inhibition of carrageenan induced rat paw edema and the results are presented in table -2. The extract of C. sativum, D. stramonium and A. indica showed 40.81%, 39.43% and 46.47% edema inhibition respectively after third hour at 200 mg/kg dose. Maximum activity was found at 3.0 hr intervals with each dose. Among these plant Azadirachta indica showed maximum anti-inflammatory activity every hour. The inflammation induced by carrageenan is biphasic in nature. The initial phase of edema has been attributed to the release of histamine and serotonin; the edema maintaining during the plateaue phase, attribute to kinin like substances and the second accelerating phase of swelling is attributed to the release of prostaglandin [12, 13]. Since the extract of C. sativum, D. stramonium and A. indica inhibited the carrageenan induced edema that involves release of histamine and serotonin in the first phase; hence the inhibitory effect of the extracts could be partly due to inhibition of mast cell mediator release.
