Zucchinis (courgettes) – A vegetable that’s really a fruit.

zucchini courgetteEnjoy zucchinis in a variety of dishes

Zucchinis, otherwise knows as courgettes, are considered to be a safe food for people with histamine intolerance. They can be incorporated into a huge variety of dishes, including:

  • slices and cobblers
  • pizza crust
  • soups
  • breads
  • salads
  • sweet cakes and muffins
  • cookies and biscuits

Zucchinis are a type of summer squash. The zucchinis we see in the shops have been harvested while young. In Britain, Ireland and Australia, a fully grown zucchini is called a marrow.

Their botanical name is Cucurbita pepo, they originated in and they can be dark green, pale green, golden-orange, or striped. Everyone thinks of zucchinis as vegetables, but botanically speaking they are fruits – “…a type of botanical berry called a “pepo”, being the swollen ovary of the zucchini flower.” [Wikipedia]Golden_zucchinis

A Brief History of Zucchinis

Like so many delicious food plants, zucchinis originated in South America. In the early 16th century the explorer Christopher Columbus brought seeds of zucchini’s cucurbit ancestors to the Mediterranean and Africa. However it was not until the second half of the 19th century that the zucchinis we know today were bred, in northern Italy. That’s why we tend to think of zucchinis as a “Mediterranean vegetable” – when they are really a South American fruit!

To make a rectangular zucchini-based pizza:


1 large zucchini
1 Tbsp. finely chopped fresh parsley
1 pastured egg, beaten
3 Tbsp. water
2 cups spelt flour
1 Tbsp. extra-virgin olive oil
½ tsp. sea salt
¼ tsp. freshly ground black pepper
Your favorite low histamine pizza toppings.


Preheat the oven to 350 °F (180 °C)
Chop zucchini into small chunks.
Place raw zucchini into a food processor and process 3 – 4 minutes until it becomes smooth and gloopy.
Add, flour, beaten egg, olive oil and parsley to the zucchini in food processor and mix until it forms a smooth dough. Add a little water if needed to achieve dough consistency.
Scoop out the dough onto a baking sheet (baking tray) lined with parchment (baking paper). Pat it out into a pizza shape.
Allow dough to sit on the kitchen counter (benchtop) for 20 minutes before baking.
Slide baking sheet into the preheated oven and bake for 20 minutes.
Remove from oven and top with your favorite low histamine pizza toppings.
Return pizza to the oven, making sure to swivel the baking sheet 180 degrees (to allow for even cooking).
Bake for another 15 minutes or until the edges turn golden brown.
Take it out of the oven and slice into rectangular pieces.

Are your antihistamine meds making you fat?

antihistamine medsAntihistamine meds and weight gain

Here’s another good reason to treat Histamine Intolerance with diet rather than with drugs: Many antihistamine meds can increase your appetite and cause unwanted weight gain.

In fact, an antihistamine medication called cyproheptadine is actually prescribed by doctors as an appetite stimulant.

Other antihistamines, such as fexofenadine and cetirizine can also stimulate the appetite. These drugs are prescribed for allergies, but one of their side effects can be weight gain.

“Histamine-1 (H1) receptor blockers commonly used to alleviate allergy symptoms are known to report weight gain as a possible side effect,” according to a report from the Obesity Society. [1]

H1 blockers (also known as H1 antagonists), are a class of medications that block the action of histamine at the body’s H1 receptor. This provides relief from allergic reactions such as hayfever, insect bites, allergic conjunctivitis and contact dermatitis.

Antihistamines are useful medications, and you should follow your doctor’s advice. However, many “allergic reactions” are exacerbated by Histamine Intolerance , a condition that can be treated naturally with diet instead of drugs.

Some common H1 blocker antihistamine meds and their brand names include:

  • Cetirizine (Zyrtec)
  • Loratadine (Claritin)
  • Acrivastine (Benadryl Allergy Relief (UK), Semprex (US)
  • Terfenadine (Seldane (US), Triludan (UK), and Teldane (Australia))
  • Fexofenadine (Allegra)

If you suffer from allergic reactions and depend on antihistamine meds for relief, consider following the Strictly Low Histamine Diet, instead, to lower your histamine levels.

Expressive writing can aid healing

expressive wriringThe Benefits of Writing

Happy New Year! May 2018 bring you health and happiness.

Who would have thought that the process of writing could actually help to heal our bodies, as well as our minds?

It’s well known that keeping a private daily diary/journal can be very therapeutic for the mind. Writing down your thoughts and feelings helps you to to understand them more clearly. A private  journal is for your eyes alone, so you can write in it without fear of judgement. Simply keeping a journal can help you deal with stress, depression, or anxiety.

Journaling has wonderful benefits for mental health, but in 1986, psychology professor James Pennebaker discovered that a particular kind of writing, which he called “expressive writing”, can have a measurable and significant effect on our bodies. Since then, further research has shown that it can:

  • make wounds heal faster
  • boost immune function
  • improve the health of asthma sufferers
  • improve the health of rheumatoid arthritis patients
  • significantly decrease the number of visits to the doctor
  • decrease troublesome symptoms of breast cancer

There may be other benefits of expressive writing that are, as yet undiscovered. It could even have a beneficial effect on histamine intolerance.  But what exactly is it?

Expressive Writing

“Expressive writing is personal and emotional writing without regard to form or other writing conventions, like spelling, punctuation, and verb agreement… Expressive writing pays no attention to propriety: it simply expresses what is on your mind and in your heart… Expressive writing is not so much what happened as it is how you feel about what happened or is happening.”

[Reference: “Write Yourself Well: Expressive Writing“, by John F Evans Ed. D. Psychology Today. Posted Aug 15, 2012]

Claudia Hammond, in her BBC Future article “The Puzzling Way That Writing Heals the Body” (2 June 2017) describes studies in which “…volunteers typically do some expressive writing, then some days later they are given a local anaesthetic and then a punch biopsy at the top of their inner arm. The wound is typically 4mm across and heals within a couple of weeks. This healing is monitored and again and again, and it happens faster if people have spent time beforehand writing down their secret thoughts.”

Expressive writing works just as well if people use it *after* they are wounded.

How to Use Expressive Writing

So how is expressive writing performed? John F Evans in his article “Write Yourself Well” suggests the following general instructions for expressive writing:

 1. Time: Write a minimum of 20 minutes per day for four consecutive days.

2. Topic: What you choose to write about should be extremely personal and important to you.

3. Write continuously: Do not worry about punctuation, spelling, and grammar. If you run out of things to say, draw a line or repeat what you have already written. Keep pen on paper.

4. Write only for yourself: You may plan to destroy or hide what you are writing. Do not turn this exercise into a letter. This exercise is for your eyes only.

5. Observe the Flip-out Rule: If you get into the writing, and you feel that you cannot write about a certain event because it will push you over the edge, STOP writing!

6. Expect heavy boots: Many people briefly feel a bit saddened or down after expressive writing, especially on the first day or so. Usually this feeling goes away completely in an hour or two.

Expressive writing costs nothing, it’s easy to do, it doesn’t take much time, it has no harmful side-effects and it has been scientifically proven to have health benefits. So no matter whether you wish to boost the healing of your mind or your body, it’s worth trying!

Stress and Histamine Part 6: Sleep

Good sleep is essential for stress reliefGood sleep is essential for stress relief

Getting a good night’s sleep is an essential factor in stress relief. It’s especially beneficial for people who suffer from histamine intolerance.

Cortisol is the “stress hormone”. When we are sleep-deprived our cortisol levels rise. [Leproult et al]

Nutritional biochemist Shawn Talbott, author of “The Cortisol Connection”, says that when we sleep for only six hours per night instead of the recommended eight, our cortisol levels rise by a whopping fifty percent!

While we sleep, our bodies cease producing cortisol, because sleep is meant for healing and regenerating. [Weitzman et al]

Stress can cause poor sleep, and poor sleep can cause stress.

If you’re sleep deprived, due to stress or some other cause, your mind does not function as well as it should. It’s harder to concentrate and to think rationally. This, in turn, can exacerbate stress.

Stress and anxiety can contribute to insomnia and restless sleep. Even when we are asleep, anxiety can permeate our dreams and disrupt our quality of slumber. It’s important to curb anxiety before you lie down to sleep at night.

Some Tips for Good Sleep

Sleep on your side

An Australian survey found that people who slept on their side reported better sleep and fewer aches and pains.  Lying on your stomach gives you the worst sleep. [Gordon SJ. et al]

Don’t hit the snooze button in the morning.

Robert S. Rosenberg, the medical director of the Sleep Disorders Center of Prescott Valley and Flagstaff, Arizona says that after you hit the snooze button on your alarm clock, your sleep will be of poor quality. You’d be better off simply continuing to sleep for that extra 10 minutes. To make matters worse, by waking up enough to hit the button then falling back asleep for a very short time, you’re interfering with your body’s natural sleep patterns.

Do not use the bedroom for work

We subconsciously associate places with activities. For example if we use our bedroom as a study or office, the brain will associate that space with working, thinking, being alert, and solving problems. Whereas your place of repose should be associated with relaxing and unwinding.
Set aside a dedicated space for work and a dedicated space for sleep.

Teenagers should be allowed to sleep in when practicable!

Teenagers need 9 – 10 hours of sleep every night, yet most adolescents only average about seven or eight hours. Some sleep even less. The hormones swirling throughout the body during puberty shift teenagers’ body clocks forward by one or two hours. This means they are naturally inclined to stay up late at nights, and then sleep in when morning arrives. (Sound familiar to you?)
Early school starts prevent teenagers from sleeping in. Over time, they build up a  ‘sleep debt’ of chronic sleep deprivation, which can adversely affect their health and studies.

Other strategies

Meditation, a warm bath, soothing music – these are some other useful tools for pre-sleep relaxation.

Good sleep is a top priority for management of histamine intolerance.

Asafoetida: the delicious spice with the weird name

Asafoetida powder

Image credit: NYPhotographic.com


Asafoetida – have you ever heard of it? We discussed it briefly in one of our earlier posts (July 2016) but perhaps it deserves a post of its own. It’s a powder made from the dried parts of a plant in the Ferula genus, which  also includes the herb fennel.  Ferula assa-foetida is the scientific name of this spice. Asafoetida is part of the larger botanical “Carrot, Celery or Parsley Family”.

This spice has many names in many languages. This, in itself, indicates how well-loved it is across the world. It’s known as A Wei, Asafétida, Ase Fétide, Assant, Crotte du Diable, Devil’s Dung, Férule, Férule Persique, Food of the Gods, Fum, Giant Fennel, Heeng, and Hing.

You may ask, why do its names range from the scrumptious-sounding “Food of the Gods” to the off-putting “Devil’s Dung?” Asafoetida is truly delicious, but like garlic, it can (in certain circumstances) smell overpowering to some people. Don’t let this deter you!

This pale yellow powder is a valuable addition to a low histamine diet. It is thought to possesses anti-inflammatory, antihistamine and anti-viral properties, and to be able to combat intestinal parasites. Some studies have found that certain substances in asafoetida could help treat irritable bowel syndrome (IBS), and may help protect against high levels of cholesterol and triglycerides in the blood.

In particular, asafoetida is a boon to people who suffer from fructose intolerance. It is an excellent low-FODMAP substitute for onions and garlic.

You can use it in any savory recipe, especially any that call for onions or garlic. It blends well with stews, soups, risottos and casseroles.

You might be able to find asafoetida in the specialty or health food section of your local supermarket. If not, try a health food store.

Stress and Histamine Part 5

exercise relieves stressExercise relieves stress

Physical activity plays a vital part in relieving stress and protecting us from its harmful effects, such as problems with histamine. Use movement to relieve stress, instead of junk food.
As a bonus, exercise promotes muscles growth. The benefits are many, whether your exercise is intense or moderate.

Vigorous exercise

When you exercise vigorously your cortisol levels rise temporarily. (Your body is primed with cortisol to help you – for example, in case the reason you’re running is because you’re escaping from danger or chasing food.)
Despite this natural rise in cortisol, vigorous physical activity can protect the body from the harmful effects of chronic psychological and physical stress.

Intense exercise like running, fast bicycling or swimming, boxing, aerobics or vigorous dancing releases tension and stimulates the release of those “feel-good” chemicals in the body that not only lower stress levels but also help to curb excessive appetite.

Moderate exercise

When you exercise moderately, on the other hand, your cortisol levels drop.  Some examples of low-intensity exercise include gardening, walking, slow bicycling, housework, tai chi and yoga. Experts say we should aim to walk 10,000 steps per day. These days we can buy step-counting devices to wear on the body.

“Physical exercise is beneficial to mental health,” concluded the authors of a 2011 study involving more than 7,000 people. [J Psychosom Res. 2011 Nov;71(5):342-8. doi:  10.1016/j.jpsychores.2011.04.001. Epub 2011 May 18. Physical exercise in adults and mental health status findings from the Netherlands mental health survey and incidence study (NEMESIS). Ten Have M1, de Graaf R, Monshouwer K.]

What’s the best exercise?

There are many different kinds of exercise to choose from, but by far the best are those that you ENJOY. If you don’t enjoy it, you are unlikely to keep doing it. Some people say there is no exercise they enjoy doing. Here are some tips:

  • join a group or exercise with a friend. Socializing makes exercising more fun.
  • Dance to music. Think you can’t dance? Who cares! Find yourself a private space and dance alone, where no-one else can see you. Play your favorite music. Turn up the volume and go wild. Dance is exercise that’s usually accompanied by music, so it combines the stress-relieving benefits of movement with the stress-relieving benefits of melody and rhythm.

What does exercising cost?

You don’t have to spend a lot of money on gym memberships to get exercise – your body is right with you all the time, and all you need to do is get up and move it. Exercise is free.

How often should I exercise?

We recommend that you move your body for at least 30 minutes, three times per week.

Stress and Histamine Part 4

MeditationMeditation – a powerful stress-reliever

It’s well-known that meditation is a powerful stress-reliever. It produces measurable biochemical and physiological changes which can be of great benefit to those who suffer from histamine intolerance. Countless scientific studies continue to provide evidence for its usefulness. For example a 1991 study found that after practicing Buddhist meditation, the cortisol levels, blood pressure and heart rate of 52 young men were significantly reduced.
[Sudsuang R, et al]

“… repeated practice of the Transcendental meditation (TM) technique reverses effects of chronic stress significant for health,” reported researchers who conducted a study in 1997. [MacLean CR, et al]

Science has shown that regular meditation can actually produce physical changes in the brain.

Types of meditation include Transcendental, Kundalini,  Guided Visualization, Vipassana, Qigong Mindfulness and Zazen (Zen).
It doesn’t matter what form of meditation you practice, as long as you do it regularly.

Meditation can be as simple as sitting or lying down comfortably in a quiet place, closing your eyes and breathing naturally. Concentrate on the gentle rhythm of your breathing, while allowing your thoughts to come and go without dwelling on any of them. Just let them flit in and out of your mind like butterflies in a garden.
Guided meditation tracks are available for free online, or you might be able to find a local meditation group.

What’s the deal with cashews and histamine?

cashews and histamineCashews and Histamine

Cashews. They’re delicious, nutritious and versatile. But can they be eaten by people with histamine intolerance (HIT)?

Opinions are divided. One blogger, who says she is a “holistic health coach”, actively encourages people with HIT to eat cashews. On the other hand, Dr. Amy Myers, writing for Mindbodygreen, lists cashews under “Histamine-Rich Foods”, as does the website for Histamine Intolerance Awareness UK.

Histamine intolerance specialist Dr Janice Joneja says: “Unless the person is allergic to them, the following are generally safe on the histamine-restricted diet as long as they are free from any additional ingredients – Pure nuts and seeds, which includes sunflower seeds, cashew nuts and coconut and their derivatives such as coconut or cashew milk. The only seeds restricted are pumpkin seeds.”

Other histamine experts insist that coconut and all nuts and seeds should be avoided. Indeed, the world of histamine intolerance can be confusing!

Which is exactly why “Is Food Making You Sick” is all about the “STRICTLY Low Histamine Diet”. According to the old saying, “It is better to be safe than sorry”, this book lists as “safe” only the foods upon which all reputable authorities agree. Not everyone agrees that cashews can be included in a low histamine diet so we recommend that people with HIT should avoid them.

Of course, the low histamine diet is not a life-long diet. It is a diet to lower your histamine to safe levels. When you’ve been on the diet for long enough to feel better, you can gradually and slowly re-introduce small quantities of additive-free cashews (or other histamine-rich foods) into your diet, while carefully monitoring your health.

Wishing you health and happiness!

Low-histamine foods are science-based

The List of Low-histamine Foods is Scientifically Researched.

Maybe you’re on a low-carb diet. Maybe you’re on a sugar-free diet, or an anti-inflammatory diet, or a fruitarian diet, or some other popular eating regime. That is your choice, but if you are histamine intolerant, your symptoms are not likely to subside unless you choose low-histamine foods and avoid foods (and external factors such as stress and pollution) that raise your body’s histamine levels.

Some popular diets are negotiable. Take the Paleo diet, for example – there is debate about whether Stone Age humans ate grains. Paleontologists have found traces of grains on ancient stone cooking tools dating back 105,000 years.

[Science. 2009 Dec 18;326(5960):1680-3. doi: 10.1126/science.1173966. Mozambican grass seed consumption during the Middle Stone Age. Mercader J1.]

Some people say that grains can be eaten on a Paleo Diet, while others insist that grains are forbidden. In other words, the foods included in this diet can be considered “negotiable”.

The foods in a gluten-free diet, on the other hand, are non-negotiable. Either there’s gluten in the food or there isn’t. Your body  certainly knows the difference! Scientists have tested foods to reveal their gluten content.

Don’t mix your diets!

The same applies to low-histamine foods. For his book “Is Food Making You Sick?” James L Gibb did not “invent” the low-histamine food list. The foods on the list have been selected because they have been scientifically proven to be low in histamine or low in factors that cause histamine release. These foods do not necessarily conform to the pattern of other diets. However this is due to sheer necessity!

As one Amazon commenter said in reply to a reviewer who complained about the book’s food list:

“Go ahead and follow your “anti-inflammatory” diet but it’s not the same as a low histamine diet. Choose which diet you need to follow, you can’t be on both. If you’re not histamine intolerant, then don’t follow a low histamine diet. The low histamine foods in the book were not selected on the basis of the latest food fads and crazes. They were selected on the scientific basis of how they affect people’s histamine levels. This is a fixed property of foods and cannot be changed according to people’s whims. Just because you don’t like to eat a certain food does not mean it is not low in histamine.”

Of course you can select your favorite foods from within the low-histamine food list, although we do encourage you to eat as wide a range of foods as possible from within the list, to maximize nutrition. If the range of foods seems very different from whatever diet you’ve previously been following, maybe that’s the reason why your symptoms are continuing. The Strictly Low Histamine Diet does not necessarily resemble any other diet. People who are NOT histamine-intolerant can go ahead and choose some popular diet craze to follow, but many of us do not have that luxury. As soon as our histamine levels rise, we suffer.

As mentioned before in this blog, following too many diets at the same time is not a good idea. It can overly-restrict your food choices. Find out if you’re histamine-intolerant (it’s easy to do, as the book describes). If you are, then there’s an excellent chance that going low-histamine will help you return to good health.

Bon appetit!

Stress and Histamine Part 3

Oriental disciplines can relieve stressOriental disciplines can relieve stress

Oriental physical, mental, and spiritual disciplines such as yoga, t’ai chi, and qigong, which combine exercise with meditation and mindfulness, can trigger the release of beneficial hormones and other body-chemicals. Reducing stress can help people with histamine intolerance.

Evidence shows that such oriental disciplines can lower cortisol levels and encourage cell-healing. In fact, studies have found that when used to supplement traditional forms of treatment, regular practice of such techniques can:

  • reduce stress levels
  • combat depression
  • improve the quality of sleep
  • keep the body flexible
  • improve the sense of balance
  • help maintain bone density
  • decrease the pain of arthritis
  • improve heart health
  • reduce hypertension


Yoga is a group of physical, mental and spiritual disciplines that began in ancient India. There is a broad variety of Yoga schools, practices, and goals.
Types of yoga include Hatha, Vinyasa, Iyengar, Ashtanga, Bikram,  Kundalini and Yin. “How to Do Yoga for Absolute Beginners” can be found here.


T‘ai-chi is a Chinese discipline. Though originally conceived as a martial art and used for defense training, it is frequently practiced for a variety of health reasons. It has become popular worldwide. Most modern styles of t‘ai-chi trace their origins back to one or other of the five traditional schools: Chen, Yang, Wu (Hao), Wu, and Sun.
“How to do Tai Chi” can be found here.


“Qigong is a holistic system of coordinated body posture and movement, breathing, and meditation used for health, spirituality, and martial arts training. With roots in Chinese medicine, philosophy, and martial arts, qigong is traditionally viewed as a practice to cultivate and balance qi (chi), translated as ‘life energy’.[Cohen, 1999]

“Qigong practice typically involves moving meditation, coordinating slow flowing movement, deep rhythmic breathing, and calm meditative state of mind. Qigong is now practiced throughout China and worldwide for recreation, exercise and relaxation, preventive medicine and self-healing, alternative medicine, meditation and self-cultivation, and training for martial arts.”How to Practice Qigong” here.

You don’t need expensive equipment or even expensive classes to practice these methods. Classes are recommended, because of the social benefit of exercising in groups, and the value of a good teacher. However if you’re really hard up and cannot afford classes, once you have learned some moves from books or YouTube, you can practice yoga, t’ai chi, or qigong for free at home.
