The concern arises from the presence of Bacillus cereus spores in leftover rice. If leftover rice is left at room temperature for an extended period, it provides an ideal environment for these spores to develop into bacteria, leading to food poisoning with symptoms such as vomiting, nausea, and diarrhea.

Some people experience bloating and indigestion after consuming leftover rice due to the increased resistant starch levels, which can reach up to 60% after refrigeration. Excessive resistant starch intake may cause temporary digestive issues as the large intestine struggles to process it effectively.

In fact, properly stored leftover rice can offer several benefits.
