Can you eat too many green beans?

Are Raw Green Beans Poisonous?

Yes, raw green beans (= French beans, French beans) are poisonous to humans. The protein is to blame for this Phasin, which sticks red blood cells together and thereby hinders the transport of oxygen in the blood.

Symptoms of intoxication usually appear a few hours after consumption. They range from nausea, vomiting and diarrhea to bleeding in the gastrointestinal tract and, in the worst case, are fatal.

The sensitivity compared to Phasin differs from person to person, as does the Phasin content from bean to bean. It is therefore possible that small amounts of raw green beans are tolerated without symptoms. But I strongly advise against trying it out.

For Infants and young children Phasin is particularly dangerous.

How do you neutralize Phasin?

By heating, e.g. B. cook in boiling water.

Cooking time so that the beans are still crisp:

  • in water: approx. 10 minutes
  • fry in the pan: approx. 15 minutes
  • stew in water or broth: 15-20 minutes
  • steam: approx. 20 minutes

Additional knowledge: Phasin is also found in other legumes, such as soybeans and chickpeas. Therefore, you should never eat them raw, but always heat them up beforehand. Peas are an exception. They don't contain phasin - you can also eat them raw.
