BRAT diet

The BRAT diet is a diet that has been recommended for people with vomiting, diarrhea or gastroenteritis. Evidence, however, does not support a benefit. It is no longer generally recommended as it is unnecessarily restrictive.

An acronym, BRAT is a mnemonic for bananas, rice, apple sauce, and toast, the staples of the diet. It is recommended that all people, regardless of age, drink plenty of fluids to prevent dehydration, along with oral rehydration solutions to replace the depleted electrolytes to avoid salt imbalance. Severe, untreated salt imbalance can result in "extreme weakness, confusion, coma, or death." The diet was first discussed in 1926.
