Coffee's effect on the gut is a mix of benefits and drawbacks depending on the person. Here's my crack at the age old question: "is coffee actually good for you". Here's some facts so you can decide if it's good for you.

## Key takeaways

- Coffee drinkers are 16% less likely to develop IBS, likely due to improved motility and microbiome benefits, this was at 4+ cups a day
- 73% of people experience faster gastric emptying and motility on coffee, so assuming you fit into the slow motility bracket it's likely beneficial in this regard
- Those with sensitive mast cells saw an 80% increase in histamine just 30 minutes after drinking caffeinated coffee, if you have violent or urgent diarrhea after coffee or have histamine issues at all this is a good case to avoid or switch to decaf for the benefits

## Does Coffee Help or Hurt IBS and Gut Motility?

- Coffee drinkers are 16% less likely to develop IBS, likely due to improved motility and microbiome benefits, this was at 4+ cups a day
- For those already diagnosed with IBS however, 40% of people identified it as a trigger. This is due to a damaged gut lining and microbial overgrowths. If you already have IBS, use your intuition and experience
- 73% of people experience faster gastric emptying and motility on coffee, so assuming you fit into the slow motility bracket it's likely beneficial in this regard

If you can't currently drink coffee, maybe even decaf it's likely because your [gut lining](https://gutfix.ai/blog/food-sensitivities-root-cause) is crying for help.

## What Does Coffee Do to Histamine and Gut Bacteria?

- Those with sensitive mast cells saw an 80% increase in histamine just 30 minutes after drinking caffeinated coffee, if you have violent or urgendiarrheat after coffee or have histamine issues at all this is a good case to avoid or switch to decaf for the benefits
- Coffee drinkers on average have 8x higher levels of some butyrate producing bacteria, meaning if your gut lining and microbiome are in tact it makes it stronger
- On the above note coffee can actually increase akkermansia levels, but you need an in tact mucus lining to reap the benefits
- Since coffee is acidic in some cases you can expect to see a reduction in E coli and other microbes as coffee slightly changes the pH of the gut. But that all depends if your environment can handle it

Overall it seems even for sensitive people decaf is much safer, all the above benefits are regardless of caffeine whereas most of the drawbacks above (besides acidity) are in part linked to caffeine.

## Should You Choose Decaf or Add Anything to Your Coffee?

Now you can make an educated choice, paired of course with your own personal experience. I do think a high quality swiss water decaf should be as talked about as any other super food however and hope to see more talking about this.

I tried to keep it focused on the coffee itself, but you're right some add ons are very helpful depending on the person also. Collagen for some is better for bowel movements. Yet to ever speak to someone who's drank bulletproof coffee, but I assume it has it's own unique benefits too. Thank you for elaborating, all dependant on the person really as many don't experience jitters or grogginess but may be beneficial for those who do, as with working on potential causes.

If your [gut lining](https://gutfix.ai/blog/fix-gut-dysbiosis-individual-food-response) reacts badly even to decaf, learning your patterns matters more than any single food rule. Learn your patterns and get a better grasp of how to save your gut lining by taking the 2 minutes quiz.
