I avoid milk 100% but I eat full-fat organic yogurt with no sugar added. I think, unless you're extremely sensitive to dairy, yogurt is generally okay because it contains very little lactose because of the fermentation. Grass-fed butter or GHEE is also supposed to be okay, as far as I understand. But I know lots of people who drink glasses of milk daily and have perfect skin, and lots of people cut out dairy completely and still break out, so there are very few hard and fast rules (as I'm learning myself these days).

Kefir and Yogurt, are the least that would break me out. Butters are fine too and they taste good.

Grains and Soy are what I should be lot more concerned about.

It's been half a year since I last tried any processed snack with corn (cheetos), I tried it once last time and had terrible abdominal pain and broke out the next day...

Yogurt has its benefits and many of the various ways dairy is problematic are reduced by the fermentation. But you'll have to figure out for yourself if it's alright for you.

Organic yogurt is amazing. No problems with it (in my case), though I don't really have a problem with dairy anyway, just lucky I guess c:

Plain yogurt/kefir should be fine. Good bacteria is required to create vitamin k and biotin plus yogurt boosts immune by increasing white blood cells. But if you have constipation problem excessive yogurt might worsen it.

I dont think the yogurt agreed with my body :/

I haven't had dairy 'concentrated' like that for many many years now and I definitely noticed after eating the yogurt I had constant pains in my stomach like 20 mins after that lasted for about 30 until I drank or ate also my stomach was making lots of noises and in general felt very uncomfortable >.<

I guess yogurt might not be ok. I think I'm kinda glad I've avoided dairy for most of my life because obviously my body doesn't like it too well regardless.

Actually, could my body just be getting used to it? Because I recall I did have dairy on a friends birthday they made cheese cake and I had some because I didnt wanna be the odd one out type thing and I recall that day also I ate things thats involved dairy and I was fine. I wonder why yogurt is the odd dairy product out for me..surely the bacteria in it wouldn't have something to do with it?

The yogurt was probably not fermented properly and still had lactose in it which is why you had trouble digesting. Change the brand and start with a few tablespoon. You can mix it with water and drink like a shake.

It's curious that everything you try causes a breakout.

It's probably best to start with very small amounts of a probiotic dairy product that you are confident has active cultures. This will help introduce the lactose digesting genes to your gut so your body has the ability to break it down.

I doubt most commercial yogurts have live cultures in them, unless they specifically say they do (and even then it's no guarantee).

I have milk protein intolerance, maybe this is what you have too? I wasn't breastfed as I refused to drink breastmilk, and I hate milk to this day. I like other dairy products though, cheese and yogurt are my favourites. The way milk protein intolerance works is that your body can't properly process the proteins in milk, and the vast majority of people with this condition hate milk as an automated response from the body. You can drink milk without feeling sick, once it's been boiled for at least 5 minutes to destroy the culprit proteins. I can tolerate milk in coffees and artificial milkshakes because milk in those is either heated or heavily processed and also in very small amounts, but if I drink more than half a pint of non-boiled I start throwing up and come out in a rash. Not everyone has such a violent reaction though, most people report just feeling sick after drinking raw milk. The more fermented/processed milk is, the less of a problem this becomes.

Milk protein intolerance is entirely different from lactose intolerance or milk allergy, the three shouldn't be confused.
