Diet and Food Guidance for G6PD Deficiency

For most people with G6PD deficiency, normal healthy eating is fine. The main food to avoid is fava (broad) beans. There is no diet that cures the condition.

The key food to avoid

• Fava beans (broad beans, also called faba beans) and foods made from them, including some flours, snacks and falafel. In some people they can cause severe haemolysis. Sensitivity varies, but it is safest to avoid them entirely.

Foods that are generally fine

• Common pulses and lentils such as dal, chana, moong, rajma and soya
• Vegetables, fruit, whole grains, nuts, milk, eggs, fish and meat in normal amounts
• Peas and green beans eaten in normal amounts

You do not need to avoid all legumes. Ask your doctor if you are unsure about a specific food.

Supplements and fortified products

• Check supplements with your doctor, especially high-dose vitamin C, menthol and some herbal products. Safety is not fully established for all of them.
• Avoid unregulated "detox", "blood-cleansing" or "immunity" products.

Sulfite and food additives

Some additives have been discussed as possible triggers, but evidence is limited. A doctor can advise if you have had reactions.

During illness

Drink plenty of fluids and eat light, easily digested food, such as khichdi and soups.

Ayurvedic view

Ayurveda suggests fresh, light and balanced food. This fits general healthy eating, but it does not change the need to avoid triggers.

See a doctor

Dark urine, jaundice or marked weakness after eating a new food needs same-day care. For emergencies, call 112 or 102.
