Answer

Inadequately cooked vegetables (eg, spinach, beets, carrots) contaminated with bacteria have been associated with methemoglobinemia. Infants and patients on gastric acid−reduction therapy are particularly vulnerable to methemoglobinemia because gastric acid production may not be sufficient to maintain low levels of nitrate-reducing bacteria in the intestine.) Fava bean ingestion in patients with G6PD deficiency is another potential dietary cause of methemoglobinemia. [35]
