My boyfriend and I have been on Soylent 1.4 for about two weeks now, but since then, our stools have an absolutely god awful smell. It’s enough to make me nauseous. I’m talking far more smelly than is normal for stool. Has anyone else experienced this? When I looked up foul-smelling stool, I came up with this: http://www.healthline.com/symptom/foul-smelling-stool
I’ve been on this diet almost exclusively, having a small cup of Soylent for breakfast, lunch, and dinner, and eating some normal food in the evening. At first, everything seemed good. I have IBS-C (constipation type) and I would only have a bowel movement about once a week. Since being on Soylent, things have been more “normal” and I go once daily in the morning now, no issue. Pre-Soylent I had issues with nausea, and I’m still having some now. Lately, I just attributed it to the unhealthy foods I was eating while on Soylent (cereal, funnel cake, lucky charms, burrito, ramen) given that Soylent really improved things bowel movement wise. Now, however, I’m not so sure all of this is a good sign. The smells don’t seem to be getting any better and I have had some diarrhea, far more than normal.
I don’t have celiac disease (tested), but I may have issues with carbohydrates/carbohydrate intolerance (will be tested in the near future) since I know IBS tends to be related to an inability to process carbohydrates. However, the fact that vitamin overdose is also a likely cause is really scaring me. Obviously, I’m going to reduce my intake and make an appointment with the GI ASAP. I still want to know what everyone else thinks and if anyone else is having a similar experience.
