I've always had a stomach of steel, I could eat anything and never feel bad or get stomach cramps... I will even go as far to say I've eat food that others have got food poisoning from and I've been fine.
That is until I went paleo.
Then when ever I walked off the beaten path I would have stomach pain for a couple days, and generally feel like crap.
Then I was at a power lifting competition and people were drinking Organic milk, which comes from mostly grass fed cows.
I thought I would give this a shot as I used to drink only milk... I mean no water, no juice it was milk or nothing 24/7. When I was a kid I used to go for 10km bike rides for time and come back and drink a huge glass of milk while I was still trying to catch my breath.
So I picked up some of this milk and tried it, no issues at all. So I figured what the hell, I would add it post workout instead of protein powder and a bunch of other crap.
I had better recovery and started making huge strength gains, my shoulder press alone has gone up 24 pounds in the last month and a half. I drink one liter post workout.
So to say the least I am digging the milk.
Now, I noticed that every once in a while I would eat something that was less then stellar not paleo and had no stomach issues the next day. So I put this to the test... You could say I found the most non paleo foods I could... and ate them. In one day to see what would happen.
Just to be clear I ate a Krispy Kreme burger and added the fried egg and bacon (if you don't know what is just Google it) followed by a deep fried mars bar. The next day I had no stomach pain at all. I eat pretty strict paleo, normally. But in the interest of since I consumed these 2 items. I did however feel a little sluggish.
(It tasted like crap by they way, no need to test it yourself, the burger that is. The mars bar was delicious)
To say the least my stomach of steel that I grew up with is back, I am just wondering what is in milk (since that is the only thing I've changed) that would cause this? I've been drinking Harmony Organic unhomogenized milk.
