Food Allergy Types

You can pretty much be sensitive to anything, but in this section I will try to put some info for you on the various known food groups that can cause problems. (This is a new page and I am gradually building it so bear with me!)

Nightshades or Solanaceae

I first came across this type of food sensitivity in relation to arthritis pain and it does indeed seem to make joint pain worse. They contain alkaloids, saponins and lectins which, for some people, especially those with leaky gut and/or autoimmune disease, can wreak havoc. 

 

Main symptoms tend to centre around joint and muscle pain, digestive problems, headaches and mood issues, especially erratic swings and depression. Insomnia and poor healing have also been linked.

 

Nightshades include:

 

  • Tomatoes
  • Potatoes (not sweet ones)
  • Peppers (bell peppers, chili peppers, jalapeno, cayenne pepper, paprika, pimento etc, but not black, pink or white peppercorns.)
  • Aubergine
  • Goji berry
  • Tamarillos and Tomatillos
  • Ashwaganda (a herb)

For more information, see the round-up of articles on Nightshade Allergy on FoodsMatter:

 

Histamine Intolerance

By rights, this should really be termed histamine excess as that's what it actually is. I have come across this more and more recently. In many, it is caused by not having enough of the required enzymes like DAO (diamine oxidase) to break histamine down in the body. 

 

I have written a few articles on this subject and been interviewed about it. See:

 

Could it be Histamine? An article I wrote for FoodsMatter, who also have a great round-up on histamine intolerance here. They have also set up a Q&A on histamine intolerance with Dr Janice Joneja, which is very useful too.

 

Treating and Diagnosing Histamine Intolerance, an interview I gave to the Low Histamine Chef, where you can find a ton of info on this subject. 

 

Two of my colleagues/friends are also good sources of info. See Ella's Red Wine Headache Cookbook and Nele's video blog about being a histamine sufferer.

 

The best Histamine Foods List we have come across - voted by my Facebook groups is this one from a Swiss source: Histamine & Mast Cell Food List. You can see their website histaminintoleranz too here.

 

There is an excellent review all about DAO here: 

 

Diamine Oxidase (DAO): what you need to know

 

Here, too, is an excellent factsheet all about HIT (Histamine Intolerance) from Nutrigold. Their factsheets are really rather good and this one is no exception. 

An excellent factsheet all about histamine intolerance. Well done them.

Histamine Intolerance Tests

You can test for histamine blood levels and DAO enzyme levels if you need to here. 

 

 

Histamine testing is far from perfect yet but we can at least see what level of histamine you have in your system and if you have enough of the DAO enzyme needed to break it down.

 

I can do those tests separately but you get the right info if you have them both done as in the Histamine Intolerance test, so that's what I've listed.

 

Don't be thrown by the name 'intolerance' though, this is a misnomer, what we are actually testing for is body levels of histamine and your levels of DAO.

 

Incidentally, you can measure histamine levels in blood or urine now just as effectively. The test is done in blood plasma or urine. I will do urine unless you ask for blood. The DAO is blood anyway.

Fructose Intolerance

Some people have more of a problem than others absorbing fructose from fruit/fruit juice. It can cause lots of bloating and gut symptoms and is linked to gut pain/IBS, espcially in children. It is linked to, but not necessarily the same as, FODMAP issues. 

 

The main fruits involved are generally:

 

Apple
Pear 
Cherry
Blackcurrant 
Watermelon
Honey
High fructose corn syrup
Agave syrup

 

Although the list is a lot longer than that. You can read a great Fructose Intolerance Primer here, which gives the longer list too.

 

You can test it nowadays using a hydrogen breath test. Note that, as Janice says in her primer above, it is important that tests do not give too much fructose as everyone would then have a problem with digesting it! This test I have linked to gives 25mg fructose, as she suggests. 

MSG/Monosodium Glutamate Intolerance

Rather than reinvent the wheel, here is a good website that will help explain the issue and give you all the sneaky names used for MSG on labels.

 

The MSG Truth website is also a good resource, and they have a useful facebook group too where you can ask questions.

 

For some interesting articles, put 'MSG' or the whole words into the search box at www.foodsmatter.com and several research reports and articles will come up. 

 

Oxalate Sensitivity

Maybe a bit less well-known than some other forms of sensitivity, some people do well on a low oxalate diet. In short, oxalates appear in a lot of foods and some people have a sort of toxicity reaction to them. 

 

I am no expert on this one so refer you to some excellent sources for reference.

 

Try Oxvox for a general oxalate 101 and Loving Your Guts has done a good write up about oxalates and oxalate dumping especially. 

 

GPL does a good page on oxalate and oxalate testing. They do an OAT (Organic Acids Test) which I have done for several people. You can get that on the Functional Tests section of the shop here.

 

Here, too, is Loving Your Guts' list of possible related conditions:

 

  • Kidney stones
  • Urinary pain
  • Autism Spectrum Disorders (ASD)
  • COPD/Asthma
  • Vulvodynia/genital pain
  • Thyroid disease
  • Cystic Fibrosis
  • Fibromyalgia
  • Join Pain
  • Chronic Fatigue
  • Insomnia
  • Hormonal Imbalances
  • Chronic Candida

Salicylate Intolerance

Salicylates can be found in almost every food and it can be very difficult to follow a salicylate free diet.

 

In fact, there is no real test for this except seeing if a person reacts to an aspirin tablet, which is pure salicylate - or white willow herb I believe is high salicylate too - we used to give it as an aspirin alternative. Obviously manage testing like this with your chosen health practitioner, but essentially if you react to that, you are likely to be salicylate-sensitive. If not, it could be other things going on. 

 

Dr Joneja, an allergy specialist, has the same way of detecting as she explains in a Q&A response she gave recently about Salicylate Intolerance.
