Potato making me sick!

(6 Posts)

Over the last year on about 6 different occasions eating chips -oven chips and jacket potato has made me vomit immediately and left me feeling really shaky, nauseaus and headachey for a few hours afterwards.
It hasn't happened with other potato based stuff like crisps, or potatos in dishes. Obviously stopping eating chips would not be a a big problem but it just seems a bit odd...and i would be a bit disappointed as i'm vegan so its one of few treats!
Is it possible to become a bit intolerant to potato?

I think it is, you might be low in potato carb digesting enzymes. It could be that you can handle small amounts in crisps etc, but not larger amounts.
I think it's pancreas that excrets carb digesting enzymes.

My friend has a nasty potato intolerance, has exactly your symptoms - but only if the potatoes are cooked certain ways. She can't eat jacket potatoes or boiled or mashed, but can have well-browned chips, crisps and well-done roasties. Apparently the proteins that cause the reaction are denatured by high temperatures.

Maybe in your case the potato 'in dishes' are cooked longer than if you just boil them, like in a casserole they'll be in the oven for an hour or more, maybe that works the same as a short time at a high temperature.

Can you eat french fries without a problem? They are thinner than chips so should get hotter inside.

Don't get me wrong, but this could be the problem b/c you are vegan, some nutrients needed to make all those enzymes are better absorbed from meat foods.
When my ds was (self-restricted) vegeterian, he became deficient in aminoacids, stomach enzymes and some nutrients, I then found out that he would have needed a number of supplements for life if he was to stay that way. In the end we went back on eggs/meat in a small way, but enough to improve his nutritional status.
I also found out that as plant cells walls are made of cellulose and humans can't digest that, we don't always get all the nutrients locked in them so you would need to eat a lot more of plant food in comparison with animal proteins to get the same benefit (this was just about zinc and it was in a range of 5 times more).
Read up on essential aminoacids, you might need to supplement some, also B vits, zinc and maybe some others. Zinc is a catalyst of lots of enzymes, inc digestive and you could be deficient in that.
