To be given milk to drink that had been open for 3 days!

[LittleMe03]

Now I expect to be flamed for this, and for it to seem really silly to lots of people....

.... but I was diagnosed with IBS around 4 years ago now after being terribly ill on and off for a few months.

I was told to keep a diary to figure out what 'triggers' caused me problems. After around a year I worked out what foods and drinks caused me to be poorly.

I love milk, will drink 1/2 a pint a day on its own or have it with cereal, I rarely drink any hot drinks. However, I soon realised that if my milk was not REALLY fresh (used same day opened or day after) I got terrible stomach pains. So even thou it's more expensive I tend to buy a pint at a time for home use and I try to avoid drinking milk elsewhere.

I nipped in to see my sister today after work, she is well aware of this strange issue of mine. She asked me if I would like a drink. I said I fancied milk but if she didn't have 'fresh' milk i would have some water. She went to the kitchen and came back with a glass of milk claiming 'I have just opened it' I drank it and soon after left.

About an hour ago I started to feel really funny, stomach pains and grumbling pains I couldn't figure out where I had gone wrong and rang my sister to check on the milk she had given me. She laughed and said it had been open a few days but it was fine so she didn't think anything of it and thought I was just paranoid

AIBU to be upset with her? I didn't say much to her on the phone other than explain that I do think that could be why I may now feel poorly tonight

When I lived in East Asia people there would say Europeans smelled like milk due to their excessive dairy intake! Never really thought milk drinking was weird till I lived there.

Anyway. What I really want to know is what chemical change goes on in thr milk once the seal is removed? The bacteria is already present in the milk and exposure to air won't cause it to deteriorate any faster than it would if the lid stays on. Or am I wrong here?

Let's reword the original post:

'I cannot eat a certain food because it makes me ill. My sister fed me this food, lying that it was something else. I now feel unwell. AIBU to be upset with her?'

YANBU.

".. extensive research into her own triggers and has made certain deductions"

Ever heard of confirmation bias? Same thing that saw my friend misdiagnose herself with histamine intolerance for around a year.

She lied because you were being silly by imagining a difference.

And yet she was unwell without knowing the milk wasn’t freshly opened...

Dairy is not for adults. What nonsense, if you like and can tolerate dairy it has lots of health benefits for adults as well as children. My FIL, BILs and most of their family were manual labourers of one type or another and needed a lot of feeding. A glass of milk with every meal was a quick, easy, inexpensive way of boosting their protein and calorie intake.
I am a fragile little petal who would curl up and die at the thought of lifting anything heavier than a credit card and cannot remember the last time I drank milk but I rely on a bowl of natural yoghurt every day to ward off indigestion and heartburn.

And butter is delicious.

there is no actual need for dairy in your diet

There's no actual need for most foods in my diet. My body doesn't need pineapple, or wine, or fillet steak, or any other single food. I still eat / drink them though.

And cheese doesn't make me gassy

There is no difference between just opened milk and three day old milk unless the milk has actually gone off.

I believe that there is. If I have two bottles in my fridge, borne with the same cat and both bought at the same time, the opened one will start to go “off” before the unopened one. I can only imagine it is to do with being exposed to bacteria in the air.

Ok so I don’t have time to find the research links but basically, baby mammals produce an enzyme called prorenin. When this reacts with hydrochloride acid in their stomach, it becomes the renin enzyme and it’s role is to coagulate the milk for better absorption.....so the milk stays in the stomach for longer.

Once a child reaches abot 6 or 7 years old, renin production stops (hence why research says babies could physiologically be breastfed until that age) and then the pepsin enzyme takes over.

As infant breastfeeding babies, we express the LCT gene which some people don’t produce effectively....meaning that lactase enzymes are fewer in the small intestine. That’s means lactose cannot be broken down as effectively....hence why some people are lactose intolerant.

It does sound as though your IBS is lactose intolerance. Try an exclusion diet for a couple of months then introduce it back in (in large enough quantities to be make a diffence). I would think without lactose or much less of it, you’ll feel a whole lot better.

Of course it will. But unless the milk is actually turned, its not going to do anything to you. In fact, even when it is turned, its still probably not going to do anything to you, and can be used as a sub for buttermilk in baking.

Drinking milk is the cause of your stomach issues. What adult drinks a glass of milk? Milk is for babies. No milkshake then then.

i drink at least a pint of milk everyday - im 33.... should i stop too MyDcAreMarvel Whatshallidonowpeople What a bizarre thing to say.

OP - if she lied to you then YANBU.

I drink milk all the time.
It is idiotic not to respect your intolerance of non-fresh milk.

I have IBS, any glass of milk, fresh or not, will give me agony and the shits.

You're a grown up, you don't need to be drinking glasses of milk at all.

I am the same OP about milk, after a day or so it smells/tastes funny to me. As a pp said, try Cravendale (or indeed any other 'filtered' milk, the co-op's is good). I find I can tolerate it on the third day with cereal, though I don't drink it on its own so can't comment on that.

You may not need to drink milk but if you like it, why is it so weird to drink it. I also like wine, crisps, chocolate, raw vegetables and shreddies.

The op has either a specific intolerance of older milk or it she doesn't like it but likes super fresh milk. Why wouldn't someone who knew about her particular preference respect that? And her having IBS is an extra reason to respect what works for her.

I'm not an hcp. I cannot diagnose the op's extent of lactose toleration. But I know without even knowing her not to piss about with the dietary preferences of an ibs sufferer.

Just to give a different perspective, I gave up all dairy for 6 months and I have never felt so ill in my life.

OP YADNBU

everyone else: Drinking cows milk as an adult is definitely a strange thing to do, where strange is defined here as something we only do because people selling us something want to make money.

So its strange, but no stranger than wearing fake tan for example.

The cruelty in the milk industry should be enough to put most people off drinking a lot of milk as adults, but then the destruction of the ecosystem that their own children/grandchildren will have to live in
should be enough to stop people drinking bottled water and we can all see that ain't happening anytime soon....

Also people are very wrong if they think the majority of adults in the world regularly drink a glass of milk a day, or consume anywhere near that much dairy. Yes it is common in America and Europe - but not anywhere else. The lactose intolerant are hardly a tiny minority when you consider that there are around 700 million of them in China alone....which is, for reference purposes, ten times the population of the UK....

I hope all the dairy phobes are getting enough calcium and vitD.

Osteoporosis is very common in older women and can result in fractures, spine collapse and serious disability.

Some people need to read or listen to the Angry Chef who debunks all this pseudoscience acid alkaline shit.

op do you drink whole milk or semi skimmed?
I do drink milk occasionally and used to drink a lot. However, since having my gallbladder removed, I cannot tolerate whole milk. So if I go out, I make sure hot choclate etc is made with semi or skimmed.
That’s obviously more to do with fat content though.

We get through 35 pints a week in our house, and plenty cheese too. The dog is gassy, and he's the only one who doesn't drink milk.

YANBU
Milk has a 'once opened use within x days'. So regardless of the use by date it will start to go off once opened like many other foods.

dairy is for babies.

Well, not quite. It's meant for baby cows. If humans are happy to give it to their babies then why not have it as an adult?
Human milk is for babies.

Yes it is common in America and Europe - but not anywhere else.

India is the largest producer of dairy in the world.

humans are mammals, and like most mammals we lose at least some of our ability to process milk as we mature and are (from an evolutionary perspective) no longer supposed to be drinking it.

Huge swathes of the adult population of the human race cannot tolerate either human or cow milk once they are adult. It is an anomaly that so many of us (me included) are perfectly fine with it as an adult.

bux they make it for us though....

our average consumption appears to be about 5 times that of an average Indian.
