Bean Gastric Problems

Gastric problems caused by beans is a mix of compounds found in the legumes themselves and microbes in the gut.

Many beans have proteins that can be hard to digest, and some are toxic to some, at least if the bean isn't soaked in water or cooked. Also, the species eating the beans can have bacteria in their gut microbiome that produces gaseous byproducts when breaking down the proteins during digestion. Combined it's even worse.

The creature will feel bloated with gas being expelled, almost explosively, out of both ends of the digestive system during this period. They feel as if the gas has built up in their abdomen and digestion is slow. They feel fuller than normal and nausea & tiredness can also come from this.

The basic treatment is avoid eating beans altogether, or only eating specific types. Sometimes the processing of leaving the beans in water to draw out some of the proteins can help as well as getting rid of any toxins. Cooking can help do the same making the beans easier to digest.

Usually it's easy to survive besides some discomfort, and potential embarrassment in the form of farts.

Similar to treating it, just avoiding beans or processing them right generally helps.

There has always been some form of these legumes being consumed for millennia and their effects are nearly always associated with them. In many cultures they make up at least some percentage of the local cuisine, and crop. They have been used as a staple or accompanying foodstuff.

The gas side effects and the bloating has led to many crude jokes found in alehouses right through to banquet halls.
