Soybean oil is a no-no when eliminating soy, right?

[3inclothdiapers]

Silly question I know... but I have some tortillas that only list wheat in the allergy alert below the ingredients list, but when I read the list of ingredients soybean oil is in them. Isn't that considered soy? Or is it okay? I'm not eliminating it yet, but after the new year I am considering eliminating soy and eggs since ds has actually shown improvement to my dairy-free diet, but not completely (he has allergic colitis, and I had assumed elimination dieting wouldn't help because it didn't help his older brother, but was surprised to see improvement this time; actually I didn't really realize how well he was doing until I re-introduced dairy and he got worse!). I'm hoping by adding soy and eggs to the list I can get ds 100% better and avoid the expensive formula (which we ended up giving ds1 because after 6 months of elimination dieting he was still unhappy and had nasty stools with blood in them).

Here is my understanding of it:

Most people who are allergic to foods are allergic to protein (and maybe sugars) not fats. That's why it's not listed in the allergy statement.

When eliminating it you should eliminate ALL sources of the food. When eliminating soy, that likely means eating no packaged baked goods. Pretty much all of them have soybean oil or soy lethicin. But if you do find you are sensitive to soy, you may be able to tolerate small amounts of soy oil later.

Most people w/ soy allergy are ok w/ soy oil and soy lecithin. NOT cold pressed soy oil though! Liam got hives when I fed him something w/ cold pressed soy oil by mistake!

But some people w/ soy allergy can't even have oil or lecithin. If you are still eliminating and trialing, I would eliminate the oil and lecithin when you eliminate soy, but trial them separately.

Yup, some soy allergic people can't handle ANYTHING soy while others can tolerate soybean oil, soy sauce, soy lecithin, etc. It all depends on the person. It's best to start out eliminating ALL and then add back soybean oil or soy lecithin or whatever to see if it is a problem or not.

I completely agree with this. I wouldn't chance it.

For an elimination diet, you'd want to eliminate all sources. This includes soybean oil, soy lecithin, soy derived vitamin E/tocopherols, and mono&diglycerides. You may be able to tolerate some or all of those, but the elimination diet is just that.

For the record, I don't react to soy-derived mono&diglycerides or soy-derived MSG. I do react to soybean oil, soy lecithin, and soy-derived vitamin E. I don't always need epinephrine if I come in contact with those, but they were the major contributors to my lifelong eczema (regular eczema and dishydrotic).

And yes, I have had life-threatening reactions to ingested lecithin and soybean oil. Needless to say, I practice strict avoidance.

The way my allergist explained it when I asked him: most soy oil is chemically processed to extract the oil, which keeps the vast majority, to nearly the point of all, of the proteins out of the oil.

Cold-pressed oils, like peanut, will have some of the proteins in the oil, and thus be much more likely to cause problems for those with that allergy.

For elimination diet, I'd err on the side of caution, then add certain uses of soy (oil, sauce, etc) back into your diet one item at a time, slowly, so that you know which item caused it if a problem crops back up.

We've never eliminate oil and lecithin and evan tests + to soy. It's never been a problem here.
