Blue avocados can be eaten. Avocado can be eaten when it is blue, and its nutritional components are not much different from those of mature avocados, but its taste is not as good as that of mature avocados, and its flesh is not hard and its taste is bitter.

Precautions:

1. Raw avocado can be eaten, but it tastes bitter and the flesh is hard. If eaten directly, it will stimulate the gastrointestinal tract, and in severe cases, abdominal pain and diarrhea will occur.

2. Avocado contains a lot of fat and unsaturated fatty acids at any time, but it can't be eaten in large quantities. Eating too much can lead to obesity and diarrhea.

3. Avocado is easy to be oxidized and deteriorated after being cut, and avocado with oxidized black pulp cannot be eaten, which will cause diarrhea, abdominal pain, nausea and vomiting.

4. Avocado tastes bad. Try to accept the unique taste of avocado before eating, so as not to cause loss of appetite.
