Sensitivities and food intolerances

I’ve decided in this entry to answer two questions which are sort of related:

1. Do you have any allergies to metal? by Shawna

2. I’m really interested in your food intolerances: what kinds they are, when and how they occurred, whether you have some medicines that help, etc. And I’m interested if you can tell something about it in general, because I didn’t find any details, I just heard somewhere that malabsorption is a symptom of Asperger’s. by Noemi

Regarding metal, I am guessing that means if I touch or wear metal, as opposed to consuming foods with, say, iron in. I am not aware of any specific allergies, either in eating or in touching, but I actually find it very uncomfortable to wear anything hard, like metal, against my body. So I decided several years ago so stop wearing jewellery or a watch – not that I wore them very much anyway, but when I wore them, I was always uncomfortable. I also find it very distracting – if I wear a necklace, or a bracelet, I fiddle with it constantly. I don’t seem able to simply forget that it’s there.

I think this is quite common with the autism spectrum – it’s part of not being able to filter things out, and as a result being hypersensitive. I try to wear clothes that are comfortable and even – exerting even pressure on my whole body, as opposed to having tight bits around the edges. I also avoid wearing belts if I can – I prefer trousers or skirts that are elasticated.

Regarding food sensitivities, I do have quite a lot of them, although I’ve never had them officially tested. I tend to experiment to see how different foods affect me. I’ve heard that the safest foods – the foods that are the least likely to cause an adverse reaction – are lamb, pears and rice, and that it’s a good idea to start with those and then add other foods one at a time, to see how your body reacts.
I find it can be hard to keep track of, because my body has a lot more sensitivity in the two weeks before my period – a lot of foods then cause me severe abdominal pain. But, at that time, lamb, pears and rice are indeed okay, so I buy a lot of them! I find eggs and bananas and avocados are good too.
But there is a different sort of sensitivity that happens all the time – a more low-level type, that can easily get mixed up with other sensory sensitivity, because it has the same sort of effect. Things like my mind feeling fuzzy or overwhelmed or having difficulty focusing, my body feeling like it’s full of electricity, as if it’s buzzing and quivering inside. It’s taken me a long time to realise that this is affected by the food I eat, but I realise now that it definitely is.
I don’t yet have all the answers – it’s something I still experiment with to some extent. But here is what I’ve found. In order for my mind to feel calm and alert and focused, and for my body to feel calm and non-quivering, I need to observe the following dietary principles:
  1. Try to avoid food with artificial additives and processed food
  2. Eat a lot of fresh, natural food – such as fruit, veg, eggs
  3. Eat raw, unsalted nuts and soak before eating them
  4. Eat small portions

The bit about eating small portions is something I’ve come to realise only more recently. I enjoy the sensory pleasure of eating, and I can easily eat too much. I know it’s very common for people to eat more than they need – but my body and mind really do seem to function significantly better on a minimum amount. 

It can actually be hard for me to know when I’m full or when I’m hungry. This is quite common for people on the autism spectrum – to find it difficult to recognise bodily cues. As a child, for instance, I used to often not realise I needed the loo until I was about ready to burst, and then I would often wet myself, because it was too late. I learnt to simply go to the toilet at regular times, to avoid this happening. Often, too, it’s not until I’m sitting quietly writing my thoughts and feelings in order to process them that I realise I’m tired, for instance. I think this is to do with the difficulty the body has filtering things out – I feel everything. My body is full of sensations, so it’s hard to filter out which ones are meaningful, and what they mean. However, I notice that when I eat less, it’s much easier to identify when I’m hungry and when I’m full – my mind and body feel clearer, somehow.

I know I have to be careful saying this, because eating too little can also be harmful. When I say eating less, I don’t mean eating less than the body needs. For me, it’s been more a case of trying to work out how much my body needs. If I am feeling tired and weak, that is not a good thing. But I can feel tired in a different way from eating too much, so I need to find a balance.

I also find it helpful to occasionally have a day or two of fasting, or eating only fruit and veg. This might be seen as strange, as it’s not a common thing in our culture, but it’s something that has been done traditionally in various cultures and religions, and I notice that it gives my body a rest and helps me sleep more deeply, so it is something I like to do occasionally.

People on the autism spectrum can have difficulty with sleeping. I find I sleep very lightly, and can wake up just as tired as when I went to bed. However, when I eat simple, natural food, and eat small portions, I sleep a lot better and am more refreshed when I wake up.

I know that it is quite common for people on the autism spectrum (especially children) to have a gluten-free diet, and sometimes casein-free too, so I should say something about this. My diet is not gluten-free or casein-free. I tried gluten-free once, a couple of years ago, just to see if it would help. I didn’t do it for very long – only a month or two – but what I noticed was that I was still getting abdominal pain with the gluten-free processed foods, and that I didn’t like the texture of gluten-free pasta, and that in general, I found myself feeling grouchy and irritable. I didn’t feel more well or more alert or anything like that. And I found it quite exhausting and depressing to be checking everything I wanted to eat to see if it had gluten in it. Perhaps if I’d done it for longer I might have seen good effects, but I have actually found much better effects on my well-being by simply eating simple, natural foods, including some food with gluten, such as pasta and bread. I am not of course saying my experience will be the same for every autistic person – I can just report on my own experience.

Regarding casein, I actually cut out milk from my diet years ago, simply because I never liked milk, and so it occurred to me in my early twenties that now I was an adult, I didn’t have to drink it any more. And I observed I felt a lot more well in myself once I cut milk out of my diet. However, I continue to eat cheese and yogurt, and have never observed any bad effects from them. I find yogurt helps my digestion, and as for cheese, I simply love cheese.

Something that helps me when I get bad abdominal pains from food is to drink hot water with a couple of drops of peppermint oil. I regularly buy little bottles of peppermint oil from Holland and Barrett.

I have actually started another blog, over on ‘Blogger’ (I wanted to try a Blogger blog, to see how they compare to WordPress) about my attempts to eat simply, and to live simply and frugally. It’s still very much in its initial stages, and is probably more useful to me than to anyone else so far, because it’s helping me track the food I buy and what I eat, and experiment with what works and what doesn’t work. But if anyone’s curious to have a look, the link is

As you will see, I don’t always stick strictly to my own rules – I do eat processed food sometimes, especially when it’s on special offer. I find it hard to stick very strictly to a very simple, natural diet. I love crisps (potato chips), for largely sensory reasons, and I’m very aware they don’t have a good effect on me, so it’s a constant struggle for me. Therefore, I try to be a bit flexible in my diet, and not too strict, because I know from experience that if I’m too strict with myself, then I’ll end up rebelling and eating lots and lots of crisps! So I try to be realistic too.
