Hayfever & Histamine

The sun is out and it’s feeling more and more like spring but this brings problems for many of us hayfever

sufferers.


The number of us struggling with hayfever is rising and it can be hugely debilitating. Nutrition can play an

important role as a preventative measure, as well as helping dampen down symptoms.



What is Histamine?


Histamine is a chemical produced by mast cells in our body as part of our immune response. It can also occur in everyday foods such as cheese, wine and fermented foods, and some foods can encourage our body to produce more histamine.

For hayfever sufferers, the immune system overreacts to pollen in the air and releases histamine quicker than the body can get rid of it. This is what causes the symptoms of sneezing, wheezing and itchy, runny eyes.


Some people suffer all year round as they lack the enzyme DAO which breaks histamine down in the body - this is called histamine intolerance and can contribute to symptoms such as skin rashes, hives, headaches, miraines, brain fog, fatigue, digestive issues and food intolerances.


What Contributes to  Poor Histamine Breakdawn & Higher Levels?



Hormonal Imbalances:

Oestrogen can hamper DAO, Whereas progesterone can upregulate it. So for those of us in perimenopause or who have ostrogen dominance, histamine can be an issue. I have often spoken to women who only started experiencing symptoms as they hit perimenopause. It also means you can struggle more depending on where you are in your cycle.


Gut Imbalances:

Food intolerances, constipation, and diarrhoea can all be symptoms of histamine imbalances. A healthy gut microbiome is key to keeping your immune system regulated and a dysregulated gut bacteria may even produce more histamine.


Poor detoxification:

If your liver and detoxification pathways are not functioning properly, then histamine may build up and be more likely to cause symptoms. Detoxification includes the gut, so this links back to having a healthy microbiome and transit time, so that histamine isn't being reabsorbed and recirculated.


So How Can Nutrition Help


When I work with clients struggling with histamine intolerance or hayfever symptoms, these are the key steps:


1. A low histamine diet


• This is a short term solution that packs a punch! It can help reduce symptoms significantly whilst we work on the underlying root causes.


2. Work on gut health


• Prioritising a healthy microbiome is key!


3. Work on detoxification pathways


• Making sure your liver, kidneys and gut are working well, are supported nutritionally and are excreting spent histamine.


4. Rebalance hormones

• Addressing any potential oestrogen dominance issues


5. Add in supplements to support DAO production, histamine detoxification and reduce inflammation

• The final part of the puzzle to support the body

Magnesium is a go-to trendy supplement at the moment, but why is that and should you be including more in your diet?

Decembers 2024 Newsletter

You probably already know that stress is not a good thing for your body and soul. Perhaps you have even had suggested to you that you should work on a stress action plan to reduce it. In theory, destressing should be as simple as breathing out, but in practice – and especially when life gets hectic - it often feels like another task on an endless to-do list. The key is in making it simple and enjoyable. Here are 7 lovely ideas you can weave into your daily routine. And the best part? They're all activities you'll genuinely want to indulge in.

The Menopause Industry Uncovered

14 October 2024
Did you see this Panorama programme? Chances are, even if you haven't watched it yet, you have heard about it. As soon as it came out I had clients asking me what I thought and saying it had frightened them. So, for what it's worth, here is my opinion on it... The menopause industry (and the health industry in general) is booming and there are so many new products, "influencers" and celebrities making promises that are just not backed by any decent research. It's massively confusing and my clients often say they are totally bamboozled, not knowing where to start. There is still such a stigma regarding HRT (a hangover from the infamous Women's Health Initiative study), that women often seek out a "natural" solution before heading down the path of hormone therapy, and an industry has been built capitalising on this. My advice would be that anyone offering you a wonder drug or quick fix, should be treated with the utmost caution! You won't be surprised when I say that I believe that diet and lifestyle modifications can make a massive difference to your menopause experience. I see it all the time with my clients, who regain their energy and feel more like themselves by making changes. Yes, I do recommend supplements to clients, but there is no one-size fits all and they should be used with caution. I always cross check any interactions with any medications and health conditions, because they can have a powerful effect. As to the programme's negative views on Dr Newson, I cannot talk about HRT levels as that is outside my scope of practice but I would suggest that she has done more to positively promote women's health than many others. The industry is thriving in part because the NHS is failing to help and voices, especially qualified medical ones like Dr Newson, are helping drive much needed change.

July 2024 Newsletter

I love the summer holidays, but the chance to break free from the normal routine of frantic dashes between the school gates and work brings with it lots of challenges. Many of my clients go into a bit of a panic as their big summer holiday approaches, rather like they do at Christmas. When it comes to healthy eating, the strategies for coping with both – and for that I mean not undoing all your previous good work – are very similar. The key is to have a plan and to be really clear on what matters to you most. Here’s my take on how to survive the summer without putting on a pound.

June 2024 Newsletter

Most people get – on a conceptual level at least – that they should probably eat a bit better than they do, they should probably move more and take the time for more self care in order to live a long and happy life. ‘Life’ seems to get in the way of achieving that. Many of us are juggling jobs and the complexities of modern relationships, leaving little time to dedicate to the business of ‘being healthy’. Convenience often wins. It’s not that that’s wrong per se, but here’s the thing: all the time we are not eating or moving or living as well as we know to do, we are silently getting sicker. That may actually be going-to-hospital sick or it may just mean having health niggles that bother us greatly but that we have learned to cope with. I’m talking here about things like IBS or other tummy troubles, PMT, arthritis, stress or anxiety, haywire hormones, or possibly weight that has crept on over the years and you can’t seem to shift it, no matter what you try. What I want to share with you today is that the food you eat matters more than you can possibly imagine. And that, in many cases, simply by making changes to your diet, the symptoms of some of these conditions can be improved so markedly that there is a really profound shift in how you experience life. 

Weight Loss: Men V Women

I hear this often from both clients and friends alike. They start a new diet and it's their partners who lose weight, whilst theirs doesn't shift.

Issue on Weight Loss

by Marcus Elliott • 12 January 2024
The truth is that calories can be misleading and by purely focusing on them can hamper your weight loss goals. Here’s why: Not all calories are created equal! Food is information for the body and each individual food will have a different effect on your metabolism. Calorie counting can be inaccurate. Food labels are based on averages and the way your food is prepared and the quality of the ingredients can affect the number of calories it contains. Calories do not take into account caloric availability. How your body breaks the food down is not the same as how they measure it in a lab.

Hormonal Imbalances

by Marcus Elliott • 16 October 2023
Your hormones regulate so many functions in the body, not just in relation to when (or if) you get your period as well as those hot flushes. They also dictate how fast your metabolism is, how hungry (or full) you feel, how sexy you feel, whether you will gain or lose weight, and they even let you know when it’s time to go to bed. These hormones talk to each other continually, and they are potent – a ‘delicate dance’. Too much or too little can cause side effects throughout the body. Your hormones can be disrupted by the toxins you absorb, stress, poor diet, lifestyle choices, and your weight. Hormone imbalance can range from feeling slightly out of balance – where you might experience symptoms like low mood or weight gain and their impact felt to a lesser or greater extent – or they might be significant enough for a medical diagnosis
