Why Fava Beans Can Kill You

What is hemolytic anemia, a condition that can be triggered by eating fava beans in some people?

• A sudden increase in white blood cells

• A rapid breakdown of red blood cells

• A condition causing severe allergic reactions

• A type of digestive disorder

What enzyme, when present at low levels, is associated with favism?

• Amylase

• Lipase

• Glucose-6-Phosphate Dehydrogenase (G6PD)

• Pepsin

Why are red blood cells particularly vulnerable to damage from reactive oxygen species when there is a G6PD deficiency?

• They are the largest cells in the body.

• They don't have any other backup protection against these molecules.

• They produce too much energy.

• They are constantly being replaced.

In areas where malaria is common, how might G6PD deficiency offer a protective advantage?

• It makes people immune to mosquito bites.

• It causes the body to produce more antibodies against malaria.

• Malaria parasites don't thrive as well in red blood cells with less G6PD.

• It strengthens the immune system to fight off infections.
