Glucose-6-phosphate dehydrogenase (G6PD) deficiency is one of the most common inherited enzyme disorders worldwide and is notably prevalent across parts of India, particularly in certain regional and community populations. The G6PD enzyme protects red blood cells from oxidative stress; when it is deficient, exposure to certain foods, medications, or infections can trigger sudden breakdown of red blood cells — a haemolytic episode — causing fatigue, pallor, dark urine, jaundice, and in significant episodes, a medical emergency requiring hospital care. Because triggers are avoidable, practical dietary and medication awareness is the single most effective way people with G6PD deficiency protect themselves day to day. This guide focuses on that dietary and trigger-avoidance guidance; it is not a substitute for the haematologist or physician who confirmed your diagnosis and should tailor advice to your specific G6PD variant.
The Food to Know About: Fava Beans
The classic and most well-documented dietary trigger for G6PD deficiency is broad beans, known as fava beans or, in some Indian contexts, bakla — the condition is even historically named "favism" after this reaction. Fava beans contain compounds (vicine and convicine) that generate oxidative stress well beyond what a deficient red cell can buffer, and reactions can be severe, sometimes occurring within hours of ingestion. Fava beans are not a traditional staple in most Indian regional cuisines, but they do appear in some Parsi, Gujarati, and imported Mediterranean-style dishes, so it is worth checking ingredient lists carefully, including in mixed-vegetable preparations, hummus variations, and some international ready meals.
Other Dietary and Herbal Considerations
Beyond fava beans, evidence for other food triggers is much weaker and more individually variable, but people with known sensitivity sometimes report symptoms with excessive quantities of foods high in tannins or specific legumes; there is no need for broad, medically unsubstantiated food restriction beyond fava beans unless a personal reaction has been observed and confirmed with your physician. More important than obscure food lists is avoiding specific herbal or unregulated supplements that may contain naphthalene-related or oxidant compounds, and being cautious with excessive vitamin C megadosing and unregulated ayurvedic or herbal formulations containing henna (mehndi) in very young G6PD-deficient infants, since henna dye has been linked to haemolysis in deficient neonates.
Medications and Everyday Triggers to Avoid
Medication triggers are more clinically significant than food triggers for most people with G6PD deficiency. Common oxidant drugs to avoid or use only under medical supervision include certain antimalarials (primaquine, and to a lesser extent chloroquine), sulfa-group antibiotics (such as co-trimoxazole/sulfamethoxazole), dapsone, nitrofurantoin, and some analgesics in high doses. Naphthalene, found in traditional mothballs, is a well-documented trigger, particularly for infants — clothes and linens stored with mothballs should be thoroughly aired before use in a G6PD-deficient household. It is essential to inform every treating doctor, dentist, and pharmacist of a G6PD deficiency diagnosis before starting any new medication, and to carry a note or medical alert card confirming the diagnosis.
Building a Safe, Balanced Indian Diet
Outside of fava beans and the medication cautions above, people with G6PD deficiency can generally follow a normal, balanced Indian diet — dal, rice, roti, most vegetables, fruits, dairy, and regional cuisine staples are not restricted. Focus instead on general anaemia-prevention nutrition: iron-rich foods (leafy greens, jaggery, lentils), vitamin C-rich foods in normal dietary quantities to aid iron absorption, and adequate folate from greens and pulses to support healthy red cell production, since red cells in G6PD deficiency turn over faster and benefit from good baseline nutritional support. Constitutional homeopathy may be considered as a general supportive measure for overall wellbeing and resilience, but it does not correct the underlying enzyme deficiency, and trigger avoidance and medical vigilance remain the core, non-negotiable management strategy.
Key Points at a Glance
Fava beans (broad beans) are the best-documented dietary trigger — check ingredient lists in Parsi, Gujarati, and Mediterranean-style dishes
Medication triggers (certain antimalarials, sulfa antibiotics, dapsone, nitrofurantoin) are often more significant than food triggers
Naphthalene mothballs are a documented trigger, especially dangerous for G6PD-deficient infants
Beyond fava beans, most regular Indian dietary staples are safe — broad unnecessary food restriction is not evidence-based
Always inform every treating doctor and pharmacist of a confirmed G6PD deficiency diagnosis before starting new medication
