As a retired British GP who discovered my own FODMAP intolerance about 8 years ago, I am SO pleased that the truth about ‘non-coeliac gluten sensitivity’ is coming out like this. It can be difficult to get this message across, even within the medical profession. Thanks for this discussion and your recognition of the value of Monash’s work (and app).

As the mother of a child with true allergies, I'm so pleased to hear someone explain to everyone a clear distinction between allergy and intolerances. People saying they have an allergy when they have an intolerance causes allergies to be seen as inconsequential when they can be really dangerous. Thank you!!

The doctor is really good at explaining the topic in a way that everyone can understand.

I am a celiac, I had no symptoms, my brother tested positive so I got tested to rule myself out and in fact I have it too. Had a scope into stomach , a biopsy , and it confirmed it. It can lead to cancer so important to know if you are celiac as you can avoid gluten and stay healthy.

Just FYI, my food intolerances and digestive issues got much, much worse over the last 2 years. Spoke to my GP, a couple of dietitians, even a gastro consultant. They just said I had IBS and try to reduce stress... In the last few weeks I developed a sinus infection and then strep throat, had to take antibiotics, and now, my digestion has never been better! Must have been a gut microbe overgrowth that none of these health professionals considered 🤷🏻‍♀️

I think a part 2 histamine intolerance session would be interesting. Can one start out as histamine tolerant but then become intolerant? If so, what are the causes? Stress? SAD? Deficiencies?

Came back to say thank you - I listened to this podcast in Spring last year and since then I've been working gradually to reintroduce foods. It's been slow, sometimes painfully so, but at some stage momentum started to build and it got easier and easier to eat more of the foods that I previously couldn't handle. My diet is transformed and I'm taking great joy in preparing delicious food packed full of beans, garlic, onion etc.. That seemed totally inconceivable to me prior to this! So thank you - keep up the good work. "Start low, go slow!"

This is the clearest, most empowering description I've ever seen of the relationship between our microbiome and our reactions to food. And it's so refreshing to be given straight information and simple hacks for getting our microbiome into peak form -- instead of the sales pitch for magic supplements and pricey tests marketed by the vast majority of half-assed health-related videos out there. My family eats mostly plant-based, but some years ago my husband developed an intolerance to soy products. They used to be a great source of high-quality protein in our menus, so I'm very excited to know that I can help him beat his 'sloppy digestion' and broaden our food choices. Thank you, Dr. Bulsiewicz! And thanks to everyone at Zoe, for everything you do.

I have struggled for three decades with food intolerance , chronic fatigue, and allergy and only very recently have come to wonder about histamine intolerance which appears to explain the catalogue of symptoms from which I suffer. I have tried so many dietary approaches including following a low FODMAP diet which helps to some degree. I always cook fresh from scratch and eat healthy foods. I was interested to hear Dr. Will advocate eating sprouted peas to increase levels of DAO in the gut ; herein lies my problem - I cannot tolerate legumes even sprouted peas as I found out recently when I sprinkled them on my salad and was very unwell for several days. The same applies with sauerkraut. I have found that the very fibre needed to heal the gut only increases my digestive problems.

This is a great program. Thank you for sharing it. Unfortunately most of the dietitians and physicians are behind the latest research. Allergy is at the bottom of their concerns. They never ask about your life style or your diet. These should be part of your annual checkup.

What a fantastic informative, affirming video. Great to hear these two people I wish all medical professionals were equally as informed. My son was in a trial for Edinburgh University for using Fodmaps. It works. 2 of my siblings have difficulties with the youngest of 4 of us affected worst. The tools you offer are so accessible, thank you..I’ve forwarded this to my son.

Histamine- thank you so much for the hacks. I definitely have a histamine problem that got worse with Covid and Ling Covid. I take DOA blockers but will sprout peas and grow my own spinach. Bought and have followed Will's book for months now with great results. Thank you so much. I have also signed up on early waiting list for Zoe UK. Really looking forward to getting going.

After 3 days and nights of no sleep because after 30 secs I’d choke on steaming post nasal drip I went to the GP who dismissed my suspicion it was food related. Bollocks. I did an elimination diet and bananas which I was having daily or more were a really problem. I live like a normal person now without eating those. I never thought I could live normally again. I am still anxious about food after being conditioned by bad experiences over years.

I’m a uk registered dietitian and I’m FODMAP trained. Thanks for an informative video and for highlighting the role of the dietitian in managing food intolerance.

Thanks for doing this video. I have allergies and intolerances, and a couple of symptoms that couldn’t be explained till now.

After years of trial and error I coincidentally took an almost identical approach to the one described. What inspired my approach was seeing the nhs method prescribed to treat my daughters MSPI (in her case incrementally going through the milk and soy ladder). I have reduced my wide spread food intolerances significantly. To avoid very bad symptoms for years I was reduced to eating the same three foods daily for every meal. Now by comparison I can eat most foods without issue and I can even treat my self to the odd Chinese takeaway (without issue). I can't believe the changes. Meat and especially fish were perpetuating my issue and hindering my guts ability to heal and get on top of the other intolerances I was trying to tackle. Removing them and going plant based was a big step towards healing. Hearing about histamine and fish makes a lot of sense now.

Fabulous episode. Zoe has made me excited about food again!

These sessions are so worth listening to. Thank you for making them available for anyone wanting to learn about better health and self care.

Thank you so much, understanding these issues have been part of my life for so long.

Since making my own yoghurt, I have finally been able to heal my gut. Pro-biotic capsules didn't work at all. Tried it for 20 years. Now I can finally eat the things I have been intolerant to without getting brainfog and tiredness.

Interesting talk. Always enjoy listening to Dr Will. He puts information over in a way that’s easy to understand.

Thank you, this was really interesting to me. I’ll be telling a lot of friends and family to tune in and I look forward to seeing more. I wanted to raise something I have observed over the years caring for my son who has Physical and learning disabilities. I’d be interested to know if you think antibiotics play a part in what is going on with the increase of food intolerance in the population. He was born with a slow got and has always experience difficulties with reflux and constipation. I have seen a correlation between my son having antibiotics, particularly erythromycin and subsequently having a sudden onset of intolerance to the foods he was eating whilst taking it. It began at only months old when he no longer could tolerant formula milk. Then, when put onto soya milk (that used to happen 33 years ago) once again he went on to form intolerance to soya, and then wheat both following further periods of antibiotics. All of these foods now give him dreadful reflux and diarrhoea. 5 years ago developed CDif (again following antibiotics for chest infection) which lasted 2 years and only resolved following faecal transplant at St Thomas in London. His gut history is chaotic but he is now at least tolerating simple plain home cooked foods and gaining weight once more. Would it be worth our while asking for a referral to an allergy clinic in the hopes of slowly reintroducing some of these foods in a slow, measured way?

I wish both of you would do a podscast on histamines. I am reading Dr B's book now Fibre Fueled and I am enjoying it. I have eczema and it developed when I was in my 70s. I am now 81.My mum had it too in her 70s. I have done all the right things in my life and have never been sick. Now in oid age, I developed eczema!!!!

Since I was in my twenties, I was diagnosed with RA, SLE Lupus fibromyalgia, asthma and the list continued to later grow. I had no idea that it all could be caused from a food allergy. My mom had all my conditions so assumed it was all genetic. I don't eat wheat, gluten, milk, soy, sugar, nuts (not including trace amounts), ultra processed foods and red meat. I'm never in remission even with losing these foods and very moderate pilates. I suppose I will try reintroducing foods and look into FODMAP. Thank you gentleman for this valuable information.

This was really informative, when working with patients we try to address all their health needs.

Thank you for verifying my hypothesis on histamine intolerance. I find that when I make my own food fresh from scratch with no additives chemicals, I have very little trouble. When I go to a restaurant that does not serve freshly prepared food, I have a reaction. I've also observed that histamine is like filling a bucket, once I get to a certain level then I start feeling it. I love that you touched on the DAO supplement. I bought some but then found that I really don't want to take a product made from porcine kidney. So I'm gonna sprout some peas as you suggested...I had been planning to do microgreen grows anyway and you just confirmed that microgreens are definitely something I should be eating on a regular basis, so this is what I shall do....

Best video ever on the topic. Never had a food allergy in my life until my fifties. It took me years to discover that dairy and gluten induced itchy rashes and joint pain. I removed them from my diet and all was well for a time. After almost two years I slowly added them back will very little difficulty until now. As I look back, I noticed that both rounds of rash occurred 6 months after a vaccination. The first was a tetanus booster the current my second MRNA Covid vaccine. I had no negative reaction to either vaccine, however, could my immune response to these vaccines have triggered and reactivated food allergies?

Thank you! I have learned so much from this video. Wish you were in Canada!

My food intolerance test has been done from my hair and it was very accurate.

I have celiac disease, my daughter does, my grandson does and my great grandson does.

Do cooked pea shoots contain lots of histamine-enzyme? Or do the pea shoots need to be raw?

I have had food allergies since my 20's which include hazelnuts, stone fruit, apples, raw potatoes. Everything but the nuts I can eat when cooked. If these foods are not cooked I get hives and swelling. I was prescribed an epipen but have learned that only my nut allergy will cause an anaphylactic response. What is the difference between the types of allergies and can I use the slow and low method of introduction to get rid of the reaction especially to fruits?

I love all the infomation that zoe gives us. Thank you so much. I'm learning.😊😊😊 !

I am only allergic to 2 foods: barley and palm oil. They both also give me asthma if I smell them. To avoid these things I don’t eat processed foods so I eat well and I haven’t had asthma once since I didn’t eat, touch (eczema) or smell them. I don’t go anywhere near the fish and chip shop when they are frying. I am not allergic to any of the common allergens.

I do want to just say, for the blood tests I do believe they are accurate. I had horrible acne and nothing was working. I finally got a blood test done and stopped eating all the foods that were high and my acne went away. Just my experience and I’m sure the acne and food intolerances are caused by something deeper but I haven’t truly figured that out just yet

Fruit, chickpeas, lentils, almonds… and the symptoms are falling asleep, nausea, painful swollen extremities, headache, dark circles under eyes.

Thank you Will. So helpfil

Very good program thanks alot!

Thanks Zoe Science for this discussion and particularly what you discussed about histamine. I was looking for some alternative of DAO enzyme for my client. DAO is quite expensive so i never prescribed to my clients as it;s not easily available in India. Will try sprouted peas now. One request, could you please do a whole podcast on histamine as there are other things that need to be discussed like mast cell activation and all.

Jonathan you look so young it's hard to believe you were setting up businesses 25 years ago. I would have thought you weren't even a pre-teen then! I had really bad dust and cat allergies as a child, I outgrew both but, I occasionally encounter a cat, not my own, who will trigger it slightly but nothing like when I was a kid and even cat saliva caused those hard, white, raised welts on my skin and my eyes would swell and close. I have had my own, mostly rescued cats since my early 20s with nary a sneeze.

I don’t think the success rate of reintroduction is as high as it is thought to be. I’ve tried unsuccessfully for the last 3 years to reintroduce foods with fructan and GOS. Symptoms keep returning and my only choice is to continue avoiding these foods. Hopefully more research will be helpful.

After listening to this I am no closer to understanding whether my problem with milk protein is an allergy or a food intolerance. i had childhood eczema due to milk and any time over the past 60 years I have consumed cream or cheese or yogurt the eczema had come back. Reintroducing them slowly simply has never worked. Now I avoid milk products altogether as eczema is a horrible painful problem.

I use a dowser to tell if a food will hurt me and so far it’s been genuine.

Curiosity about science and nutrition.

Thank you on the lactose training info. I see ice cream in my future.

Thanks for the tip about sprouting Peas.

I'm a Ceoliac. Since discovering this I have had to make everything myself and cut out all processed foods. So your quote that people with intolerances always eat only processed foods to their diets is completely wrong for many Ceoliacs.

I have histamine intolerance. Some foods cause me to break out in itchy welts within 20 mins after eating. Other foods cause me autonomic nervous system effects within 2-3 hours, and other foods cause nausea and diarrhea that feels like acid. I have been allergic to shellfish for about a decade and coffee for about 5 years. I did not have the significant issues with food until after having alpha and delta covid. I did an elimination diet for about 3 months and gradually started adding foods back. I have established that I can tolerate cheese but not milk, I can safely eat avocado, eggplant, tomatoes, fermented foods. I cannot tolerate spinach--it makes me feel like I've drank 10 cups of coffee. I avoid strawberries and banana completely.... last time I ate half a banana I had what I can only describe as a conscious tonic seizure that lasted 10 minutes.....I could not control my limbs.... it was the scariest moment of my life. I need to see an allergist for sure.

Very interesting

i was diagnosed with eosinophilic esophagitis 10 years ago by a specialist in Australia, I react to the protein in white potatoes (no chips/french fries - argh!!!!) but since moving to the uk they say my blood test says I am not allergic anymore, but I'm too scared to start eating them again as it's a kind of invisible reaction but has horrible long term consequences. I wish I could be certain. I do miss my spuds!!

Definitely we need for information and progress

In uk, the advice is to breastfeed solely for 6 months and yet he says introduce different foods at 4-6 months.

No mention of glisophate, or other chemical additives to our food through the years since the 1960s… also, check out Zach Bush and the Virome and his gut health tonic xx

Are people just getting diagnosed more now? In the past it was less recognised.

I had a terrible intolerance to fruit in pregnancy, so painful. I craved fruit but couldn’t have it as one bite would give me terrible and agonising bloating.

I suffered a lot of with dairy and gluten

Very interesting video! I recently had a genetic test show a lactose intolerance (got the recessive gene from both sides, mum and dad) but I want to speak to my doctor again to see if there's anything I can do to manage it in the best way possible without making my symptoms flare up... it's a WIP for sure as there's so much conflicting information out there!

There’s no way I could reintroduce potatoes into my diet for example as I have to wear gloves when I peel them or I get a terrible rash. Eating them causes extreme joint pain, as do all nightshades. Being in a room with one tomato plant caused my whole body to itch & my throat to become scratchy. Many of the very bad food intolerances I have now at age 56 were never problems in the past, they came on suddenly after anaphylaxis caused by an antibiotic.

Hi guys, thank you for this hugely helpful podcast. I wondered if you could help answer a question please? A few years ago I had some skin prick tests with an allergy consultant. I reacted to birch pollen, timothy grass and latex. The consultant suggested I also avoid foods in those groups. There were really long lists for each. Some of them, like nectarines, I know give me an itchy throat. Others I thought I was perfectly fine with. I am struggling with bloating, constipation, adhesions from surgery and acid reflux. Would you still recomend an elimination diet, as discussed in this podcast, or should I take some of these pin prick results into account? Many thanks, Jen

From general reading and my curiosity in science, I can think the gut biome as one of three possible allergenic factors that would exacerbate or ameliorate intolerance of food, the central one. The others being genetic predisposition in the basal metabolism, and metabolic changes induced with certain combination of food or prescription drug ingested. Sidebar: Famous sci-fi author and filmmaker Michael Crichton, a MD by training, had it all wrong in 1969, in his best-seller novel The Andromeda Strain. As a group of US gov't scientists were called on to deal with a sequestered extraterrestrial virus in an underground state of the arts( ?of the sciences) autonomous lab, they were all 'ultra' sterilized ( pasteurized?!) as a prophylactic measure prior to picking apart the exo-virus in their pressurized biohazard suit. That prep procedure alone would have put their body into shock and killed them, never mind what havoc the unknown virus would've brought.

Are peas not something you want to avoid is testing a histamine intolerance? Slightly confused about that when mentioning sprouted peas

Thank u very much

Jonathan, be very careful not to mis-speak when talking about food intolerances. At 21:35 mins, you say there are no reliable blood tests for food allergies, when you mean food intolerances. There are effective skin prick and blood tests (looking of IG response and levels) for food allergies. The food elimination diet is only done for food intolerances. It would be too dangerous for food allergies. My daughter has a milk protein food allergy and gets anaphylaxis with the tiniest amount. So the distinction is absolutely critical.

Bearing in mind the importance of eating spinach at the ‘right moment’ is it healthier to buy packed spinach or unpacked bundles of spinach leaves?

If I consume any dairy I get sour stomach and suffer gerd with backwashing it up. I Never have diarrhea but will have some bloating. It has gotten worse through the years. It is horrible. So I use a alternative soymilk. Real quality cheese and yogurt tolerable in limitation.

I have an intolerance to caffeine. If I ingest caffeinated beverages or medication that has caffeine I get nausea to the point of vomiting. Luckily it's not difficult to completely cut it out.

Egg white now makes my throat swell but the allergist says it’s not a true allergy (skin prick test). It’s swells badly and lasts for about 1-4 days. The problem is I can’t find anyone else who gets this reaction. I don’t know what it is or what to do about it.

I wonder if our immune system has too little to do it tends to over react when food gets put in the body.

Can it start with a flu shot I took mine last April n post that developed some allergies which never existed before

How can i find a dr in my area that works w8th this kind of thinking? Are there zoe drs?

I am hyper allergic to indoor mold spores. Do you have any treatment or solution?

1:45+ Have food allergies actually increased, or is it an increased diagnosis of gut problems?

0:25 What evidence is there that people who remove dairy or gluten from their diet go on to add “highly processed” foods? Are those not the very people most likely to be motivated to eat more healthy foods?

IgE testing revealing high histamine level means histamine intolerance? Or allergy or intolerance? Please let me know

The title is misleading... this isn't really about food allergies; it is 99% about food intolerances.

I think this is wrong. If the immune system is not involved at all in food intolerances then how can it be such a huge part of autoimmune illness.

How can my IBS be triggered by onions but not shallots, leeks, garlic or spring onions? I am guessing that there is some biochemical produced by onions but not by the other family members.

My problem is nuts. And all dairy alternatives tend to be nut . Vegetarian options are often nut based . Nuts give me migraines and flushing .

Sesame was added as a food allergy.

Food intolerances are just as danderous as allergies. Some people will tolerate trace amounts of the allergen before reacting and becoming distressed. Large amounts will cause serious consequences. Allergies have not changed since birth for many and only the reactions have varied over the years. A food intolerance is not overeating and becoming gaseous.

Can this help vestibular migraine?

Can a person have both allergies and intolerance?

Are the histamines filtered by the kidneys? If so do the kidneys suffer by doing the work?

Thanks for the video. It is great to see more information coming out about diet and food intolerances etc. Does Zoe plan to do a video about SIBO or small intestinal bacterial overgrowth as that is a condition that is not talked about much in the UK and I have it? I have multiple food intolerances due to this and ended up becoming very malnourished. I actually felt better when I did not eat or drink anything apart from water. Nobody was helping me due to lack of knowledge so I ended up doing my own research. I tried the FODMAP diet 3 times which did not help me and my dietitian had no more advice. I did a full exclusion diet to discover all my safe foods etc. I started with white rice and water and every 3rd day I introduced one food item. If it caused problems it went on my bad list then I allowed time for my gut to recover before introducing something else. It took a long time and lots of willpower but I did it. Very long journey with Sibo and I learnt so much. I cannot tolerate dairy, beans, legumes, most fruit and veg, fiber, fermented foods etc. My absolute worst thing is garlic but I was intolerant to that long before Sibo arrived. If I eat any garlic I cannot eat anything for days afterwards as my gut is so inflamed.

My genetic testing showed two genes for celiac disease. I am pretty sure I am sensitive to wheat but don’t know if I have full celiac disease. I’m wondering how I can find that out?

Something that can't be overlooked is all the crap we are spraying on food growing in the field, GMO's, the way even our grains have been scientifically modified. These problems were rare before the 80's and 90's. I wonder if they have the same problems in countries outside of western diets.

I have had 5 anaphylactic reactions and I’m only 6!

omg eggs KILL me.... I was eating them for years... always had GI symptoms (bloating, gas)... I assumed it was normal... as years progressed, and until recently had experienced the WORST symptoms. Constant several bowel movements a day, cramping, fatigue... I will NEVER touch them again.

21:53 “… work with a dietician who is facile in these topics” Oops - “facile” actually means the opposite of what he intends 😬

Just wait ‘til “they” have others (not themselves) eating mosquitoes, roaches, etc., instead of meat.

If you have a child with ANA reactions, PLEASE look up Southern California Allergy Institute. This is a safe, proven approach. Food intolerances should not be confused with food allergies. This video is misleading, especially to people not familiar with the severity of food allergies.

What if you ARE tye person that gets diarrhoea after just 2 drops of milk 😭

Just eat meat and veggies. Period.

This would be more convincing if he clearly wasn't reading a script
