While the list of suitable foods is extensive, there is one important dietary trigger that should be strictly excluded. Other G6PD triggers can also include certain medicines and chemicals, so food is only one part of managing the condition.
1. Fava Beans, Also Called Broad Beans
Fava beans are a well-established dietary trigger for people with G6PD deficiency. Eating them can cause favism, an acute haemolytic reaction in which red blood cells break down rapidly. Fava beans contain compounds such as vicine and convicine that can promote oxidative stress in people with G6PD deficiency.
Never intentionally feed your baby fava beans, and check packaged foods carefully for fava beans or fava bean ingredients.
2. Tonic Water and Quinine
Quinine is a known medication-related trigger for haemolysis in people with G6PD deficiency. Tonic water can contain quinine, although babies should not be given tonic water in any case.
If you are breastfeeding a baby with G6PD deficiency, do not make dietary restrictions or medication changes without discussing them with your healthcare professional. The American Academy of Pediatrics notes that most foods in a breastfeeding parent's diet do not need to be routinely avoided.
3. Other Potential Triggers
G6PD deficiency is not managed through food alone. Certain medicines, infections and chemicals can also trigger haemolysis. Your baby's healthcare provider should give you a personalised list of medications and substances to avoid based on your baby's specific G6PD variant and clinical history.
Do not rely on internet lists of foods, dyes or supplements as a substitute for medical guidance.
4. A Note on Other Legumes
There is often confusion about whether soy, chickpeas, lentils and other legumes need to be avoided. Fava beans are the classic food trigger associated with G6PD deficiency; other legumes should not automatically be treated as equivalent triggers.
If you are unsure about introducing a particular food, ask your paediatrician rather than unnecessarily restricting your baby's diet.
