Yes, there are a lot of idiots out there - clearly “avoiding grains”  is not the same as “fasting”. I prefer to stick to the meaning of the characters, “bigu fasting was the common medical cure for expelling the sanshi三尸 (Three Corpse), the malevolent, grain-eating spirits that live in the human body”

 

It is valuable to understand cultural and historical perspectives if you are seeking truth, consider that people in the past believed they were dying en masse due to demonic possession, but it was actually tiny bacteria or pathogenic viruses spread through crops. They had no technology or science and could not see atoms, molecules, bacteria, or viruses.
 

Many people in the modern world abstain from grains, which is backed by science and mostly related to gluten. Gluten, a sticky protein, damages the intestinal lining with regular consumption. As it became a staple of the modern Western diet, the health of the population steadily declined.

You will be fine if you eat rice, as rice does not contain gluten.

I usually ate potatoes, rice, and buckwheat, but last winter I ate a lot of wheat and dairy. Usually, in the spring, my body would start a light detox through the release of phlegm and mucus, with 3 days of a runny nose and mild discomfort. This spring, the detox was very intense and prolonged. Now it’s clear why.
