I have spent the last year and a half eating primally and experimenting with this and I've finally figured out that eating pork really just doesn't agree with my stomach, but I don't understand why. I know that there is more polyunsaturated fat in pork (and with chicken) but would that really make such a big difference? I don't eat it often and I've tried both grass-fed and normal pork and there really doesn't seem to be a difference. The fat is especially tough on my tummy.
Eating pork that has not been cured (as in bacon) or marinated (vinegar) has been shown to cause blood coagulation and clotting as many as 5 hours after consuming it. Live cell analysis observed this. Cured and marinated pork did not produce this effect. The resulting symptoms can vary but lethargy and fatigue often occur. Apparently traditional cultures that rely on pork know this and prepare it accordingly.
I have been getting sick as well within an hour or so of eating it. I just read that it is one of the hardest foods to digest. So since I have IBS I'm assuming the digestion issue with pork is the reason. No other meat gives me these symptoms.
It makes me nauseous! A few years back my husband brought home honey ham for christmas, a half hour after eating it i threw up violently - he ate it too and was fine, happy, great, go figure!! He actually thought i pretended to vomit because he said it was the best thing he had ever tasted. The smell of raw bacon makes me gag, but i can eat it cooked, the fat seems to bother me the most. Are humans meant to eat pigs???
It's likely an individual sensitivity due to a lack of proper digestive enzymes. Pork is not bad for everyone, but there's no need to eat it if it makes you feel sick. You could try adding enzymes like lipase (for fat digestion) to your routine if you still wanted to try.
I also have digestive issues with certain types of pork, often diarhea following a stomach ache. I think it has to do with the animal feed. Even pastured pork is often fed soy and grain and much of that even comes from GMO sources (such as the popular USWellnessMeats.com source) so be aware of your choices. I've always noticed wild and grain and soy free pastured pork never gives me digestive issues. Also farmers commonly lie about what they feed their animals so it's always worth visiting the farm personally and having a checklist of questions if your health means anything to you.
Do try pastured pork. I was a near vegetarian for so long for some reasons: I had not realized that the awful meat I was eating (once, then I did not want to touch it for at least a week) was in fact CAFO meat. You can go to more expensive butchers, they will still sell you CAFO. Pastured meat was a revelation. I still find significant differences (in digestibility) between pork and chicken bought from my trusted guy, and that occasionally bought at the farmer market. In particular ham goes from a so-so, heavy food from the best food there is.This guy (2 hrs south of here), will get my business for as long as I live here.
