This may sound like a stupid question, but I woke up with a fever the other day. I thought it was just me going into a flare. The fever ranged from 99-101. The next day the fever was gone, thankfully. I didn't feel sick or like I was coming down with any other sickness. The day before I ate a substantial amount of peanut butter (I'm a peanut butter addict). I know it sounds really stupid, but could it be that my body doesn't react to peanut butter well and it caused the fever? I've read before that you can be addicted to foods that you are intolerant to, and I'm definitely addicted to peanut butter. I'm wondering if it could cause an inflammatory response that could have set off the fever. Maybe this is totally off the wall, but I wonder if it's possible.

I don't think food could cause that. May have been you had a little 24 hour bug that caused your temp. JMHO

Peanut butter does have significant inflammatry proporties, but causing a fever is pretty extreme. Not impossible though.

Peanut butter does not agree with my daughter since she developed Crohn's. It DOES cause her cramping, etc, and so is clearly riling up her digestive system.
However, if this is the first time this has happened then I agree with Nanners -- could be a bug.
Daughter (22) Dx'd Crohn's 3/06. Misdiagnosed for two years, including by top pediatric Crohn's specialist as stress. No symptoms for the past two years. Recent colonoscopy shows stricture gone but still two spots of inflammation in TI. Used LDN to taper off Entocort. Was on Entocort since April 06. Never had D. 4.5 mg LDN, SCD multivit, homemade yogurt, 5000IU vit D3, 500 mg calcium, 27 mg iron, monthly B12 shots, daily oral B12 1000. SCD diet modified to include potatoes and rice.

In Crohn's, your gut bacteria are not normal. A reaction to them can cause a fever. It may be that eating a lot of peanut butter could result in bacteria that you react to multiplying and causing a reaction.

Then there is the problem of just eating a lot of peanut oil in the peanut butter. That will slow down your digestion - you can only digest about 6 - 7 grams of fat per hour and your small intestine will slow down until digestion is more complete if there is undigested fat in the mix. Slow clearing of the SI can allow bacteria to grow there and could account for your fever - and the fading of it after the peanut butter had passed through.

yeah Never actually thought of it in that exact way before, but yes, I'd say so. I have the same sort of response if I eat fatty/oily foods in too great a quantity or without digestive enzymes. I think of it as the food triggers the Crohn's bug which causes inflammation and fever. Sometimes my belly is downright hot as well.
To me, running a fever is always a sign the bug is on its feet and looking to kick *ss, and my diet is wrong.
And yes, I too was a peanut butter addict, ("Hi, my name is Cowpat Ken...") until the time they took me into hospital after yet another bout of "appendicitis" after eating peanuts, when they whipped out my vermiform appendix and said the residual inflammation would die down. It's been 25 years and I'm still waiting... eyes
Now, if I'm feeling Cresta Run suicidal, I can manage a single jar before all H*** lets loose.
