Lettuce often gives me diarrhea, and I end up with undigested lettuce in my stool. It's like shitting a salad. Any idea why? Should I just not eat lettuce? It's not the dressing, in case you're thinking that, because I never use dressing.
Because humans cannot digest cellulose. Plants need to be cooked to break the cell walls for them to be digestable better. Then why doesn't everyone get this? I guess due to differences in gut health and flora.
Lettuce is high in insoluble fibre. So my thinking is that you need to balance it out with soluble fibre, like a starchy carb. This is the basis behind the helpforibs.com website - I don't agree with a lot of the dietary advice on there (i.e it's anti-red meat), but as someone who swings between constipation and diarrhea, I am able to minimize symptoms by eating some soluble fibre (banana, rice, yams, beets, etc) at every meal, along with whatever sources of insoluble fibre in that meal. Soluble means it absorbs water, forming a gelatinous consistency that helps normalize bowel symptoms.
I get this too, but only when I don't thoroughly rinse my lettuces/spinach/kale/etc. Even the bagged "pre-washed" varieties. I lived in California during a particularly nasty E. coli spinach outbreak and that was enough to convince me to take the extra step.
That said, cellulose or no, I mow through pounds of greens every week in the spring, can't seem to get enough of the stuff. Very satisfying.
Lettuce = Rodney Dangerfield of vegetable. Gets no respect. Dean pretty much hit the nail on the head but I'll add in some more to consider.
Bacteria from cross contamination. Maybe try different brands?
You're eating to much fiber. Lettuce is pretty much water & fiber. Maybe try to limit your serving size.
You may have an intollerance to Gluten. While that alone won't cause your symptoms, the damage it does to your small intestines will. I had the same issue untill I went on a Gluten Free diet which allows the intestines to begin to reverse the damage. After about a year I noticed my issues with lettuce went away. Hope that helps.
Many restaurants put preservatives on their salads to keep them "looking" fresh. Many people are allergic or sensitive to this preservative and hence the stomach may get upset. You can also feel dizzy, wanting to throw up, diarrhea and cramps. Some people may have flu like symptoms such as sweaty hot/cold sensation on top of everything else. It’s a reaction that our bodies have for our protection to get the poison, as I call it, OUT of the body. I have heard that food poisoning happens between 18-48 hrs. after eating something bad…NOT TRUE!!! There are different kinds of food poisoning. True, it’s more difficult to place blame legally unless several people have had the same experience at the same place and at the same time with the same food. On the other hand, if one is not use to eating salads, the roughage from the lettuce can act like a cleaning agent with its fiber until your body adjusts to eating such healthy foods, but in my experience, this will not happen in such a short amount of time. But poison to your system, well some bodies react fairly quickly. Think about how fast some medications work when simply digesting it.
I love Olive Garden but it is tough to eat there when the salad causes such immediate reaction of intestinal distress. Last night I could hardly make it home(to the bathroom). Certainly all of these postings and comments should make OG think twice about their products. I, and my friends, can no longer eat there and not fear an "episode"!!!
