I had severe colon pain after ingesting mayo made with avocado oil and peanut butter with added palm oil (not the same day). This got me researching oxidized oils. If you look at pubmed there are a ton of studies implicating oxidized (heated) vegetable oils with colon damage and cardiovascular damage. Incidentally, olive oil has a healing effect on these issues.
Anyone have anything to say about this?
I don't know anything about the oil, many people with IBS swear by the fodmap diet and avocado is a red flag. Just a thought. Maybe try the vegan mayo. It is both dairy and gluten free.
I did a bit of research myself into this a while ago. This article has some useful information about oil choice for cooking with:
If the oil had been kept too long at room temperature (or even kept in the fridge but for too long) then it would turn a bit rancid, and when we have IBS our guts get really hypersensitive and react more strongly to things we really shouldn't have eaten.
Are you in the UK? I ask because there's a peanut butter here that contains ZERO additives, any other oils, sugar, sweeteners, salt etc, and it is delicious. It contains nothing but peanuts. It's not even expensive and Tesco stock it. The jar has "100%" written on the label (because I have forgotten the exact name of it.)
Also, if it was mayo you ate, did that contain raw eggs? Those can definitely upset the gut. If mayo is made at home it should be refrigerated after making it and eaten within a day.
You might want to consider what else you ate on that occasion or on that day, or even the day before. The time it takes for food to reach the colon after eating is several hours minimum. There are other triggers for colon pain besides food, especially infection (which would usually mean contaminated food rather than a food intolerance). Sometimes wearing tight clothing can cause digestive discomfort especially for people prone to bloating. In any case I’m sure you didn’t just eat mayonnaise on that day, you’d typically eat a number of different foods and any of them could potentially cause an IBS flare up. Supplements can also cause issues especially things like inulin powder and greens powders which are potentially a source of fermentable fibre.
Someone mentioned FODMAPs and I personally found eliminating and reintroduction FODMAPS under the supervision of a specialist registered dietitian the most helpful strategy. It’s not a diet for life, it’s a diagnostic tool. The reintroduction phase is crucial to identify where the problem lies. Sometimes it’s the total FODMAP load that causes issues, also called FODMAP stacking which means small amounts of lots of foods you might otherwise tolerate have added up and exceeded your personal tolerance threshold, hence the symptoms
It can sometimes be very difficult to know what causes an increase in symptoms and playing food detective is one way to end up with food anxieties and cutting out one thing after another. That’s why I recommend people seeking out a properly qualified registered dietitian with specialist training in this area. If that’s a realistic option for you. What I don’t recommend is finding some backstreet “nutritionist” (not a protected title) who has some made up qualification from the Institute of Holistic Google or the like.
