Millions of years of evolution and experience have helped us to know what not to eat so as not to die, but there are certain foods that we consume quite frequently that, without the correct preparation, can be poisonous:

1 Walnuts from india

Some packages promote them as "raw". However, eating raw Indian walnut would intoxicate you because it contains a chemical called urushiol that is also found in poison ivy (it is the one that generates itching, swelling and pain when you come into contact with it).

To eliminate this toxin the nut must be toasted in the open air, because the smoke can severely damage the lungs of those who breathe it.

2 Honey

Honey is considered a superfood because of all the properties it contains, but few know that raw honey contains toxins that could cause dizziness, vomiting and liver damage.
Commercial honey goes through a pasteurization process to eliminate the alkaline pyrrolizidines, a toxin.

3 Potatoes

Specifically the potatoes that already have flowers or roots in them. These roots contain something called glycoalkaloids : the same chemical that we find in the most lethal plants in the world, like the dulcamara. The glycoalkaloids attack the nervous system and generate discomforts such as diarrhea, vomiting and dizziness.

4 Casu Mazzu cheese

This cheese is known as the most dangerous in the world since its processing requires fly larvae that accelerate the aging process. The problem? Some of these larvae survive and cause problems in the digestive system, including bloody diarrhea and constant vomiting. Delicious.

5 Raw red beans

These innocent red beans should not be eaten raw (as if we needed to say it). They contain a toxin called phytohaemagglutinin that causes diarrhea, nausea, vomiting and very sharp abdominal pain. These symptoms generate dehydration that in severe cases can take you to the hospital.

To eliminate the toxin, beans should be soaked and cooked well.

6 Elderberries

Although they are used to make jams and pies, this little berry contains in its seeds a good amount of cyanide , the same substance that spies used to commit suicide before revealing information.

To avoid death or coma by poisoning, the berry should be opened and shelled perfectly.
