Why is it everytime I eat French Fries from Mcdonald’s, I end up getting diarrhea. I eat fries from other take out places and i’m fine. I eat potato chips and other related food items and i’m fine too. Is it the oil they use, a chemical?? ---

Weird. I’m prone to diarrhea – lactose intolerant – yep, that’s what it means – don’t eat dairy and expect to leave your house for awhile. Just think of Haagen Dazs as a laxative. But McDonald’s fries have never had that effect on me. Too bad, too – cuz they’re not bad. ---

Could be a fat substitute, like Olean \. One of the side effects is (I’m not making this up) _anal leakage_. That can’t be good. I talked to a medical buddy of mine, and the explanation is that the stuff is so slippery, it slides right through. * * * From Hell’s heart, I stab at thee- ---

If thats what your ‘medical buddy’ actually told you, I’d advise him to crack open the books again. Olean doesn’t run through you because its ‘slippery’ - it is simply indigestible. I don’t believe McDonalds or any other fast food company is using it - a lot of customers would get upset. ---

Actually it seems to be the Hamburgers that have that effect on me, not the fries. I am sure they do not use Olean. The first time I ever tried chips with Olean I was up all night sick, so I did not eat any for a long time. I have since begun eating the Fat Free Pringles that are cooked with Olean. They seem to have no effect. So either it was psycosymatic (sp) the first time or it just happened that I got sick at the same time. If I were trying it for the first time I would do so only at home when I was not planning to go anywhere else for quite a while even into the next day. Jeffery ---

I’ve heard that excessive fat in general can cause the “green apple splatters”. Maybe McDonalds fries are greasier than all the other fires you’ve tried. ---

Is it every McD’s or just those in your area (the same franchise) ? Maybe someone is trying to save a buck, or not cleaning as well as they should. If it’s universal then who knows. ---

What’s in those fries… Potatoes, partially hydrogenated soybean oil, natural flavor, dextrose, sodium acid pyrophosphate (to preserve color). Cooked in partially hydrogenated soybean and corn oils, TBHQ (to protect flavor), citric acid, dimethylpolysiloxane and natural flavor.

Dimethylpolysiloxane sounds pretty slippery to me. Like some kind of lube or detergent. I had some fries from Mickey Dees yesterday and they are getting worse. Strong chemical taste. Gak ! * * * “Hope is not a method” ---

Hey, everybody bitched about McD’s cooking fries in lard (yum). So I guess this is what we get. Personally, I’ll stick to Jack’s 2 for $1 tacos. Now that’s eating. * * * Wow, 00, I made it! 🙂 ---

God how I miss Jack tacos. There is no Jack in Kansas - and I miss them so much. I may have to relocate back to somewhere civilized just so I can get those yummy tacos. ---

I told her they were the best worst tacos she’d ever eat. And guess what? She agreed! And now I think she’s hooked on them too 😃 Yum Yum! * * * “How wonderful it is that nobody need wait a single moment before starting to improve the world.” - Anne Frank ---

White Castles are called sliders cause they slide in, and slide out. Alas, they are also lacking in Kansas. They taste great! Never gave me the runs either, though the complain is common with them. ---

Oh Fuzzy-wuzzy, you have no idea what you’re missing. Imagine, if you will, a piece of dingy, grayish colored matter shaped in a 2½" x 2½" square, approximately 1/8" thick and smelling like a dirty sweat sock. They poke 5 holes in it, about 1/2" in diameter, one in the center and one near each of the 4 corners. It’s then smothered in onions, steamed and placed on a soggy, gooey steamed bun with a single slice of dill pickle placed on top. Don’t bother to try to open it to add condiments, as the combination of the mystery meat, onions and bun being steamed together gives it the consistency of half dried Elmer’s glue. Now order 25 of them, because no respectable connoisseur of fine White Castle dining would attempt to consume anything less than that, and plan on spending the next 4-6 hours sitting on the throne. Mmmm Mmmm Mmmm, now doesn’t that sound truly delectable? 😉 😉 Back where I come from, we call them belly bombers. And in spite of (or maybe because of) how disgusting they are, they’re so popular that they even sell them in the freezer section of the grocery store. Just zap them in the microwave and serve.

The worst fries on my system: Red Robin. A lot of people I know can’t eat them either. StrTrkr, you may have an inability to digest protein, if it’s the burgers that get to you. Does only McD’s effect you, or all beef products? BTW, my sister’s dog Toby can tell the difference between chains’ fries. He hates McD’s, loves Wendy’s. * * * “That was a hell of a thing.” ---

Can’t say that McDonald’s food gives me ‘The Big D,’ but it definitely is the most effective laxative known to mankind. Better than Ex-Lax, a cigarette, you name it. * * * “You had me at ‘Hell no.’” [Next page](https://boards.straightdope.com/t/my-ass-and-mcdonalds/6173.md?page=2)
