What to know about fava beans
Fava beans carry a genuine safety warning that most foods do not: in people with G6PD deficiency, the most common enzyme deficiency worldwide, eating fava beans can trigger favism, an acute breakdown of red blood cells (hemolytic anemia). The beans contain vicine and convicine, compounds that create oxidative stress the G6PD-deficient body cannot buffer. On top of that, fava beans are one of the highest-FODMAP legumes, topping the scale for galacto-oligosaccharides (GOS), and are high in nickel.
Watch for
- Favism risk: in G6PD deficiency, the vicine and convicine in fava beans can trigger hemolytic anemia, with jaundice, dark or cola-coloured urine, fatigue and shortness of breath appearing 1 to 3 days after eating them.This is a medical emergency, not an intolerance
- Highest galacto-oligosaccharides (GOS) rating and top-of-scale total FODMAPs, so fava beans bloat a sensitive gut even in small portions
- High in nickel, relevant for systemic nickel allergy
- High in lectins, so they must be cooked thoroughly
