Does anyone here who is lactose or casein intolerant have a delayed reaction to them? I'm trying to figure out if that is what is going on with me. I wonder if you can react a day or two later?
Thanks! Dinah

Hi Dinah,

Yes. A day or two later is common with any kind of food intolerance including casein. That's what can make it so tricky to tell if you have one

Hi Dinah, I am going through this same issue myself. I'm trying to figure out if casein intolrance or LI is still causing me problems. For me, sometimes I react within a half hour of eating dairy (especially if its alot) other times its the next morning or afternoon. Delayed intolerances are so hard to figure out. I've started keeping a food journal again so I can trace back 3 days. I read that intolerances can show up as late as 72 hours after injesting whatever it is that you are intolerant to, so a day or two is within that realm. I hope we can both figure it out soon!

Usually, food reactions can take anytime between the first 24 hours and three days

I am permanently lactose intolerant and very much so. I just discovered that
some candies have lactose now:

Hershey's chocolate bar
3 Mustketeers
Reese's peanut butter cups

I don't recall "lactose" ever being an ingredient - I learned this because I
ate too much Halloween candy and had to keep running to bathroom
more than usual. I read the labels after I consumed the candy and to
my surprise lactose is in there. I don't know if they always had lactose
in them and just didn't print it on the label or if it's a new change; I feel
it's new because I've eaten candy like this before and no problems and I've been
lactose intolerant for over 30 years now. So all Halloween weekend I
am picking on chocolate candy and it's acting like a laxative. I was
wondering why I was making bowel movements at 2 AM. And lactose
reaction is funny - it all depends on what other food you've consumed before it
and how much lactase your body is still making. Everyone is different and
has different levels of lactose intolance. I know I need my food to be 100%
lactose free.

About chocolate candy and lactose - all milk chocolate will have some lactose simply from the milk that is one ingredient. But lactose is also commonly used as a sweetener in chocolate, so some chocolates will have even more lactose because of that.

I can tolerate the small amount found naturally in the milk chocolate, but when
they add it as an ingredient, I cannot.

I am only mentioning this as a source of lactose in case someone has lactose issues and didn't
know it was in chocolates as an ingredient and not just naturally occurring.

I'm kind of a wierd LI. I usually react quickly to any milk but I can tolerate some amounts. I can have butter and aged cheeses, even cream cheese but not fresh milk or cream, no ice cream. When I was experimenting with the enzymes, I would still react but it was delayed for a few hours, meantime I swelled up like a balloon. Yuck...

I am exactly like you. Can tolerate the milk in a cappuccino but no more, no cream or ice cream, but cheeses, yogurt, sour cream, etc. are all A.O.K. (although I still avoid milk chocolate).

This sounds alot like myself too! My reaction is the next morning. Thank you for posting.

What symptoms are people having to casein? I'm trying to figure out what foods I can tolerate and can't.

I react with bloat, intestinal cramps, gas, big D. I also get congested, have a thick throat and tiredness. My DD reacts differently. She has a stomach ache, congestion, tiredness and worst case, vomitting.

The things is we're each different and can present with different symptoms for the same trigger. You would do well to just go off dairy for awhile and write down how you feel. Then you can try it again and note how it makes you feel. If you are sensitive, you will have a definate difference in the way you feel.
