Can leftovers and rice be cooked together again? Is it harmful to your health? My mother-in-law doesn't know what she thinks. She used to be better, leaving leftovers in the rice cooker.
This is actually inappropriate. If the leftovers are cooked too many times, some chemicals in the rice will react with water, which is likely to produce substances harmful to the human body. In addition, according to common sense, eating too much leftovers is unfavorable to the intake of body nutrition, so I suggest that your mother-in-law cook as much as she says every time, and don't be reluctant to throw it away.
