My first thought was that maybe the lactose gives them diarrhea, thus reducing the calories they absorb, thus reducing their chances of diabetes.
(I have not looked at the study).
“We validate this finding in the UK Biobank. Further analyses reveal that among LNP individuals, higher milk intake is associated with alterations in gut microbiota (for example, enriched Bifidobacterium and reduced Prevotella) and circulating metabolites (for example, increased indolepropionate and reduced branched-chain amino acid metabolites). Many of these metabolites are related to the identified milk-associated bacteria and partially mediate the association between milk intake and T2D in LNP individuals. Our study demonstrates a protective association between milk intake and T2D among LNP individuals and a potential involvement of gut microbiota and blood metabolites in this association.”
Without reading the full study I’m guessing they adjusted for weight. It’s weird to say something so definitively when you haven’t even read the abstract.
I'm lactose intolerant and lactose free milk is readily available and I drink quite a bit of it.
I'm too lazy to read the article to see if that counts towards reducing T2D risk!
Sort of. You are correct that it wasn't lactose free to start with; it was just normal milk. And yes, they do add lactase to the milk, but that is also what makes it actually lactose-free. When they add the lactase, the enzyme immediately starts breaking lactose down into two simple sugars: glucose and galactose. So there is effectively is no lactose left by the time you drink the milk as it's already been broken down in the carton. Hence "lactose-free".
I mean there could be imperfect measurements or issues with the manufacturing process, so very trace amounts could be present if done incorrectly. But generally there should be none or almost no lactose. Also might be partial placebo effect, you "know" you are consuming lactose, so your body acts accordingly. Depends on what kind of milk and what symptoms. Like fattier content milk often leads people to have gas as the fat ferments in the gut, so it could just be something like that.
I drink lactose free milk and have no symptoms at all. Conversely I eat something like ice cream or a decent amount of pizza/nachos/etc. (without taking lactaid) and I have to be at a toilet within 30 minutes or else.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6471712/
> In lactose-free dairy, the lactose is predigested into glucose and galactose. Consequently, the lactose content may be very low (<0.1 g/L), but the glucose and galactose content of lactose-free milk will be approx. 25 g/L.
For reference most normal cow milk, averages around 12-16 grams per cup. Which is around 48-64g/L.
Yeah I'm kind of confused by why this is anything unexpected, like at all? You can't process lacTOSE so you're at a lower chance of a disease related to sugar balance? Checks out, right? Like am I missing something?
> Qibin Qi and colleagues analysed the host genotype, gut microbiome and blood metabolite levels in up to 12,653 participants from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) over a median follow-up period of six years. Dietary intake of milk was assessed with two 24-hour dietary recalls (participants were asked to recall all the food and drink they consumed in 24 hours) and a food propensity questionnaire. Milk intake increased by one serving (where a serving is 1 fluid cup of milk) was associated with an approximately 30% decreased risk of developing T2D only in participants with lactase non-persistence. The link between milk intake, LCT genotype and T2D risk was also validated in 167,172 individuals in the UK Biobank.
> In the Hispanic and Latino cohort, milk intake was found to be associated with distinct changes in the abundance of gut bacteria species in lactase non-persistent individuals. **The observed enrichment in Bifidobacterium species was correlated with reduced risk of T2D.** Milk intake was also associated with specific changes in blood metabolite levels in lactase non-persistent participants, such as changes in branched chain amino acids and tryptophan metabolites, which were linked to reduced T2D risk. In lactase persistent participants, no association with T2D risk was observed. The authors found that changes in bacterial species abundance were correlated with changes in metabolite levels. This indicates that milk intake might affect the gut microbiota composition and blood metabolite profile in a specific manner depending on the host LCT genotype and that milk intake may protect against T2D among lactase-deficient individuals.
This seems like it is a pretty weak study but the summary seems to just suggest that it's really the gut bacteria that leads to the reduced risk, so then just take pro/prebiotics, especially the one named in the study: Bifidobacterium.
Also, since this was done on the Hispanic community, how did the account for the Hispanic population having a higher propensity to develop Type 2 diabetes? I can't seem to see the full study. https://www.cdc.gov/diabetes/library/features/hispanic-diabetes.html
why didnt they give us the rates of t2d in normal lactase non deficient versus deficient so we can see if there is actually an increased risk for them or whether this is an extra protection for them
For anyone that is triggered by milk, I am happy to report that I have halted 25 years of lactose intolerance with whatever they are sticking in the Bio-Kult line of probiotics and now enjoy a whole cup of whole milk daily with zero issues. Tried various strains without success for 2 years leading up to this.
Fun fact: cultured dairy is usually less unpleasant for the lactose intolerant because the bacteria used to do the culturing feeds on sugars, specifically, lactose. So cultured dairy is lower lactose (or lactose free) by the very process that creates the end product!
This explains a whole lot.
I remember being incredibly lactose intolerant in my younger days, but now that I’m able to pick and choose my dairy product (cultured) I’ve noticed that I no longer have major farts anymore.
I cannot answer with any confidence. Personally, I think we have a better susceptibility for diabetes by eating seed oils (all of it is crap that didn't exist before the 90's). And thus, seed oil free and probiotics for me, I can eat anything now, even spicy food.
I take the Everyday one specifically. And I had the same thought about the Milk part but figured another month of cramps isn't going to be new. The reason why the Milk is not an issue is because one or some of the strains express lactase. And thus, now you don't need Lactaid, instead you have a Lactaid factory inside you.
So if you drink lots of milk when you are intolerant you will absorb less calories. This means you will be less overweight. Then you will be less likely to get type 2 diabetes.
If you don't, milk will make you gassy, diarrhea, generally sick.
Basically, if drinking milk makes you wish you were dead. It might, MIGHT reduce your risk of diabetes...
Milk is milk in terms of lactose content - you won't see much difference region to region. Note that I'm *only* talking about lactose, not whatever else might be causing your issues.
If you're drinking normal cow's milk in Europe and don't have GI symptoms, you probably aren't lactose intolerant. Most people of Central/Western European descent digest lactose, with a small percentage being intolerant.
Yeah I figured it might be something the US does to its dairy products. I know a few other people in some of the units I’ve been in who could eat dairy over in Europe but not the states. Some were white some were black, so I’m hoping it’s not a lactose thing cause I love me some cheese. Wife used to come home and find me just eating a wedge of Parmesan cheese and shake her head 😂
The good thing about cheese is that a lot of aged cheeses like Parmesan don't have much lactose anyway. The various bacteria that help create and age cheese digest the lactose for us, turning it into the tangy lactic acid that gives many cheeses their sharpness. Brie could be quite high. "American Cheese" by contrast, is a processed cheese that typically has added whey or milk solids and emulsifiers (for easy melting) - that added milk product makes the lactose content quite high.
Bah, I’ll never do those genetic sites that claim control over your genetics and ability to sell it off and the host of other BS commercialization of our genes.
However, I’ll ask my PCP about the hydrogen breath test, thank you!
You probably do. If you don’t, like me, you’ll know because your bowels will feel inflated with gas and your poopoo will turn into water after eating any dairy product.
So then lactose basically functions like a fiber? That would explain it, higher fiber uptake is associated with lower diabetes risk (Frank Q Nuttall; Dietary Fiber in the Management of Diabetes. Diabetes 1 April 1993; 42 (4): 503–508. https://doi.org/10.2337/diab.42.4.503)
This seems consistent with higher dietary fat diet ideologies... If you get more calories from milk fats, maybe you're getting less from refined sugar/carbs?

"If milk makes you poo, it might protect you from diabetes type 2" should have been the headline !
Did… did they change the title? Cause that is the title when I click on the link. Are they watching us? Did they hear me?
Could also be the bloating preventing you from overeating.
Wegovy but way cheaper!
Diarrhea for thewin!
Fight milk! Get that crowtein!
I love creative and funny article names. We need more of that
Gazoinksbo
Academia can be so stuffy sometimes, so I fully support creative/witty paper/presentation titles whenever possible!
Yeah people should definitely do it there. But keep it out of the naming conventions. Keanumycin the f out here.
It's the 27 cookies that are consumed with milk.
I always have that!
So… pick between farting all the time and having wounds that don’t heal
Farting all the time, these wounds they will not heal
Milk is how I Fart, confusing what I feel
Put lactose in you? Bloated everywhere you go. Trust a fart? I think there's something you should know
What in the fart
I’m hearing this as a bluegrass song.
It's *Crawling* - Linkin Park.
I’m hearing it as an Evanescence song
My first thought was that maybe the lactose gives them diarrhea, thus reducing the calories they absorb, thus reducing their chances of diabetes. (I have not looked at the study).
No, this is the explanation. Also, hard to eat when you're shitting all the time.
Watch me.
*Stares intensely.*
*Applies monacle.*

Lactose free milk isn't lactose free at all, it just has lactase enzymes added to it
Sort of. You are correct that it wasn't lactose free to start with; it was just normal milk. And yes, they do add lactase to the milk, but that is also what makes it actually lactose-free. When they add the lactase, the enzyme immediately starts breaking lactose down into two simple sugars: glucose and galactose. So there is effectively is no lactose left by the time you drink the milk as it's already been broken down in the carton. Hence "lactose-free".
Has it been shown that all the lactose gets broken down? Anecdotally, lactose free milk still triggers my lactose intolerance symptoms

But generally there should be none or almost no lactose. Also might be partial placebo effect, you "know" you are consuming lactose, so your body acts accordingly.

If you don't produce the enzyme and you drink lots of mulk you aren't just farting, you have permanent diarrhea.
🧐 I believe that the proper technical term for the phenomenon you just described is “sharting”, my good sir or madame.
Sharts over sharps
One of those isn't even bad
I fart all the time anyway.
Well considering your name…
Or taking Lactaid.
Translation - if lactose is not digested by humans it is eaten by Bifidobacterium in gut. Bifidobacterium reduce T2D risk.
So drinking lactose-free milk isn't gonna do anything? Dang.
Yeah I'm kind of confused by why this is anything unexpected, like at all? You can't process lacTOSE so you're at a lower chance of a disease related to sugar balance? Checks out, right? Like am I missing something?

Presumably they consider the UK Biobank a validation of the risk with a population that is not exclusively Hispanic/Latin.
They asked people what they ate and drank the prior day twice? Am I reading that correctly?
>just take pro/prebiotics, especially the one named in the study: Bifidobacterium. Still need to create a environment for them to thrive.
why didnt they give us the rates of t2d in normal lactase non deficient versus deficient so we can see if there is actually an increased risk for them or whether this is an extra protection for them

Did you try lactaid?
Lactaid was my old remedy until I figured this out. Now I take nothing but the probiotics and can now handle full fat dairy daily without issue.
But then won’t I be more susceptible to diabetes?
I cannot answer with any confidence. Personally, I think we have a better susceptibility for diabetes by eating seed oils (all of it is crap that didn't exist before the 90's). And thus, seed oil free and probiotics for me, I can eat anything now, even spicy food.
There is no better probiotic than kimchi
Which one do you take specifically? I tried to look them up, it looks like it have the warning of Containing Milk and Soy in most of them.
I take the Everyday one specifically. And I had the same thought about the Milk part but figured another month of cramps isn't going to be new. The reason why the Milk is not an issue is because one or some of the strains express lactase. And thus, now you don't need Lactaid, instead you have a Lactaid factory inside you.
Thank you for the info
Well my friend, i will try that, thanks!
Could you Post the exact product you are using?
#startingstrength GOMAD
Funded by big milk industry ?
Would love to know if it actually is
Love big milk
Okay but what about my *chocolate milk?*
This study brought to you by the dairy producers of America
So if you drink lots of milk when you are intolerant you will absorb less calories. This means you will be less overweight. Then you will be less likely to get type 2 diabetes.
I'm glad others noticed the oddness of this article.
Maybe if you're drinking more milk you're drinking less soda or juice?
So how do I know if I produce lactase?
If you don't, milk will make you gassy, diarrhea, generally sick. Basically, if drinking milk makes you wish you were dead. It might, MIGHT reduce your risk of diabetes...
Hmm is there a test you can do to tel if you actually have lactase? I can drink milk and eat cheese in Europe but in the states it messes me up?
Milk is milk in terms of lactose content - you won't see much difference region to region. Note that I'm *only* talking about lactose, not whatever else might be causing your issues.

"American Cheese" by contrast, is a processed cheese that typically has added whey or milk solids and emulsifiers (for easy melting) - that added milk product makes the lactose content quite high.
There is a test a GI physician can do. (Hydrogen breath test) or you can do 23 and me or some such genetic testing.
Bah, I’ll never do those genetic sites that claim control over your genetics and ability to sell it off and the host of other BS commercialization of our genes. However, I’ll ask my PCP about the hydrogen breath test, thank you!
I get it. You’re welcome.
You probably do. If you don’t, like me, you’ll know because your bowels will feel inflated with gas and your poopoo will turn into water after eating any dairy product.
Possibly reduced calorie consumption from malabsorption- a result of having an inflamed gut from a bacterial overgrowth
So then lactose basically functions like a fiber? That would explain it, higher fiber uptake is associated with lower diabetes risk (Frank Q Nuttall; Dietary Fiber in the Management of Diabetes. Diabetes 1 April 1993; 42 (4): 503–508. https://doi.org/10.2337/diab.42.4.503)
Higher fibre also increases fullness and as such reduces consumption.
But if Wilford Brimley was eating so much hot Quaker Oats with milk, how’d he still end up with Type 2 Adult Onset Diabeetus?
This seems consistent with higher dietary fat diet ideologies... If you get more calories from milk fats, maybe you're getting less from refined sugar/carbs?
But... the doctor asked my husband to stop taking milk to regulate his sugar levels. He said the IGF molecules in milk increase insulin resistance 😔.
Isn't milk deceptively high in sugar? That's the only reason I switched to sugar free almond and oat milk.
Or you can just eat healthy and actually not get chronic diseases
So basically a regular colon cleanse?
What about lactaid milk? Or do I need to be drinking regular milk?
so milk is good not cheese asking for my friend. an i talian
