OK, my turn.
First off, I want to say that I do NOT have a week or sensitive stomach. Indeed, I am immune to many “normal” digestive side effects (example: I do not get increased bowel movement from eating lots of fruit, peppers, fat, citric acid or sugar; I basically have an iron digestive system). It is normal for me to go a year at a time with no nausea to speak of. To the best of my memory it has been at least 2-3 years since the last time I threw up.
I have now had 2 violent bouts of nausea directly attributable to Soylent bars. Throwing up on two separate occasions in a week is basically unheard of for me. Like, I’m almost certain this has literally never happened before unless I had a severe stomach bug, and even then I can’t actually remember such an incident.
It’s not just that, though; I got diarrhea, too. That is: my body is clearly responding to this as though it were food poisoning (indeed, I thought the first one was bad fish) except that food poisoning takes 12-24 hours and this takes, uh, about 4.
Having said that, it’s clearly not just the Soylent bars, because like everybody else, I had a bunch of bars and it was fine, and then I had several in a row that clearly messed me up something awful.
My soylent bars have not been exposed to heat, or any other environmental factors that would cause problems. Indeed, I’m almost certain the bars themselves are fine, but as my kids just ate a bar from the same box, we’ll find out shortly.
In my case, there’s something that could be an obvious difference, which is that I’m now taking a multivitamin where I was not before, which leads to my current theory: I think what people are experiencing is a situational overdose of some vitamin that’s causing the effects in people who are sensitive to it.
(I’m taking a multi because I’m crash dieting; typically less than 1,000 kCal/day; it’s not optional. I could try a soylent bar without the multi, but at this point I’m completely terrified to try them again. I really really REALLY don’t like nausea.)
Every day I’m taking a B complex, 2k IU vitamin, calcium, a multi, and a few other irrelevant things. It’s not the vitamin D (I’ve taken 15k IU with no side effects), but it might, for example, be too much niacin. I’m not an expert in this stuff, though. For my idea to be correct, all of the following would have to be true, and I have no idea what fits the bill:
A substance that:
- can cause nausea, vomiting and diarrhea
- can vary substantially in how much people take in from day to day (or how much is actually in peoples’ systems from day to day)
- appears in large amounts in soylent bars, enough to send sensitive people over the edge
So, yeah, no idea what’s up there. Good luck. I’ll report back (with the box number) if anyone else that consumes bars from this box has any issues, but I don’t think anyone will.
Oh, yeah, my gf had a box from this box last night; no issues. So yeah, it’s not the bars by themselves, it’s not an allergy (because I had a bunch and I was fine); it’s some combination of the bars and particular people under particular circumstances.
