Potatoes were introduced in Europe in the 16th century, and has since then been a regular feature of our history books. Though its appearance can be linked to other unfortunate instances of nature like crop failure and severe famine, it is and will continue in all probability, to feature prominently in the diet of most western families. Much like tomatoes, the stem and leaves of the potatoes too contain poison. This includes the potatoes itself if left to turn green, with it being indicative of high concentrations of glykoalkaloid poison. Instances of poisoning due to potatoes are rare and far between, but it does happen often and on. Common symptoms are a period of weakness and a state of confusion that can lead to coma, followed by even death. Consuming green potatoes or drinking potato leaf tea has been found to be the prime reason for causing most deaths due to potato poisoning in the US in the last fifty years.


First, an interesting piece of information: tomatoes came to be considered as vegetables in the US as per a US Supreme Court order of 1893, though in the rest of the world, it continues to be designated as a fruit; or a berry, to be more precise. All of it had to do with a tax that was levied on vegetables but not on fruits. However, it is interesting to note that technically, a tomato is nothing but an ovary. A chemical called ‘Glycoalkaloid’, present in the leaves and stems of the tomato plant can lead to the occurrence of extreme nervousness and stomach upsets, though they may be used to enhance flavor in cooking. However, they have to be removed before eating. This makes a huge difference as far as taste is concerned while this method of cooking also preventing poison to seep out in appreciable quantity. Also, sprinkling a little sugar on the tomatoes further enhances their flavor. Now the thing that needs to be sorted out is whether they are ‘toe-mah-toes’ or ‘toe-may-toes’.

Almond that exudes the best flavor are the bitter almonds and not the sweet ones. It is their strong scent that has made them extremely popular in many parts of the world. However, there’s a flip side though, for they’re full of cyanide. This makes bitter almonds to be dangerous if consumed without proper processing done to remove the poison. Unfortunately, in spite of such a requirement, some countries have deemed it illegal to sell bitter almonds, with New Zealand being one of them.

However, the same cannot be said if one chews and consumes a large number of them, and can even lead to death if apple seeds in sufficient quantities is consumed. A single apple simply does not have enough seeds to make one fall ill, let alone die, but one will do good to avoid apple-eating competitions.

Only the flesh of the pufferfish is considered to be eatable since it is believed to contain the poison in far less concentrations. It is in fact, considered a delicacy in many parts of the world like Japan or Korea. Such is the poisonous nature of pufferfish, referred to as fugu in Japan, that chefs dealing with it need to undergo special training that spans from 2 to 3 years and are required to clear a set of tests so as to obtain the mandatory certificate of practice. Apart from a written test, the chef will have to demonstrate his cutting abilities with him actually consuming the parts that he has cut forming the culminating part of the test. The tests are demanding, so much that only about 30% of the applicants make it through. This does not mean that the rest die due to consumption of fugu fish since they can fail in the earlier rounds as well. The poison causes a slight tingling sensation of the mouth and it forms the only food that the Emperor of Japan is legally barred from eating, keeping in mind his safety and health concerns.

  1. Yes, I have heard that apricot seeds have arsenic, but didn’t realise that almonds had them too. May have to go for walnuts then as they have omega 3 which is cleansing and anti aging, and good for detox to clense the body. Looks like we may need to check all nuts to make sure they’re safe.
