start a food diary and keeps notes about how you are feeling throughout the day. the culprit will reveal itself eventually.

I think the trouble with grapes is the pesticides, at least for me. Conventional stuff always causes me issues, while stuff labeled organic from a farmer's market does not. I've got the same issue with cherries.

Since you've taken antibiotics, clearly your gut flora needs replacement. The usual stuff applies: kefir/yogurt (make it yourself for best results), sour kraut, pre-biotics, probiotics, etc. Once you've got that squared away those, you'll notice a huge improvement.

Another thing to worry about is whether or not you have the proper acid levels, which you can test with Betaine-HCL or digestive enzymes. You'd worry about this if you're having a meat only meal and it feels like it just sits in your stomach like a rock and doesn't move. In that case, on an empty stomach take a pill, one at a time, upto no more than 6 and put your hand at the top of your stomach and feel for heat. Once you feel heat, that's the dose you should take. If you don't feel any heat and you've reached 6 pills, try eating a meal right after that and see how you feel. (Don't take these pills on an empty stomach and then skip a meal as you might get acid reflux - always eat something with protein after you do.)

Note that this will change once you start to properly absorb minerals like zinc, magnesium, potassium, etc. which are needed to generate the proper acid levels. You'll want to supplement with these as well, at least until you're healed.

As for yeasts vs bacteria, if you have bacteria, going Very Low Carb/Zero Carb will eliminate them. With Yeasts, it's the opposite, you want the good bacteria to fight off the yeasts as yeasts have mitochondria and can eat ketones/fats. There's an episode of Chris Kresser's podcast where Paul Jaminet is interviewed that they go over this stuff, highly recommended listening. I believe it's this one.

Also cashews are probably something you want to avoid, if you can afford them and find them, try macadamias instead. Cashews aren't nuts and they've got a high n6 PUFA content.

Also see if you've got a sensitivity to FODMAPS.

The spots on your skin sounds like you have an allergy to something, so you'll have to work at it to find out what.

Try some L-Glutamine and see if that helps, in addition to it's carb craving silencing qualities, there's some stuff out there I've read that says it helps heal digestive issues.

Another thing to use is coconut oil as it helps us with leaky gut and is a very easy fat to digest incase you've got bile or liver issues. Plus it's antibacterial, but it only kills the bad stuff. Try a little bit of it in your coffee (or tea) each morning and work your way up to a tablespoon a day at most. If you do too much at once, you'll get the runs, so start slowly.

This happened to me. Have you looked into fodmaps sensitivity? Coconut milk, onions, and cabbage are on the list of highly reactive foods for me.

Also, bone broth and products with probiotics might be helpful (kefir, kombucha, etc.) in healing your sick gut. I'm still a work in progress, but hopefully this might help for you.

I've experienced this from time to time. While I would have described the pain that I,ve had as too much acid it is actually as deficit. The cur that has worked for me is 2 tsp of apple cider vinegar in an 8oz glass of water 10-15 minutes before a meal. If u like u can add one tsp of maple syrup as well to make it more palatable but it is not paleo that way.

If you're like me, you have seriously damaged gut flora that will most likely take years to heal. Try an elimination diet by eating a small selection of foods that tend to be easier for you to digest. For me, that is ground beef, eggs, sweet potatos, and brocoli. Then add in foods and see if something in particular is causing it.

I agree that probiotics are good. I made up a batch of yogart from half & half that seems to be helping a lot! I've been eating it for 2 weeks and my digestion seems improved.

The main thing is to keep experimenting, and don't forget that you didn't break yourself over night and you aren't going to fix yourself overnight either.

By the way, have you been on anti-biotics recently? I've noticed a lot of people tend to have gut trouble after a round of them. I'd have to be about to die to take another oral anti-biotic myself.

Thank you for all your replies! I do keep a food diary but I'm not very good at weeding out the culprits.. I know I cannot stomach grapes of any colour, they just don't digest. I'm eating: chicken, beef, sometimes fish, sometimes lamb, beef and chicken are the main meats in my diet, veg includes broccoli, carrots, lots of cabbage, frozen peas, almonds, occasionally cashews. I was taking antibiotics for a series of 8/9 months for acne in 2009/2010, which might have had a big affect. I've taken a few antibiotics in my lifetime on top of that course of them too. I'm on medication every day for depression, which I'm trying to come off..but you can't just stop taking them. I'm tempted to get a candida & parasites test done but they are really pricey! Does anyone have any tips on flora and gut healing? My personal trainer thinks it's to do with yeast overgrowth and parasites, but I'm not feeding them any sugar so I thought this would be helping, but I'm not eating any chocolates, sweets, dairy or grains! Just lots of meat and veg and occasionally some fruit and I snack on almonds. I have some probiotics from QUEST which are free from everything, so I could try to take those, I also tried super vitality greens but I think this made my skin flare up again with spots, I seem to get spots when I take supplements so I try to avoid them!
