Poisonous Potatoes? Your Spuds Can Kill You!

Potatoes are a staple food in North America and many other places of the world, but did you know this spuddy delight could possibly kill you? In 1978, a large group of boys in a school suffered from severe diarrhea and vomiting. 17 of them even required to be hospitalized and the 3 most severely affected children were even comatose. The cause? Eating a significant amount of toxic potatoes.

But how could potatoes, something the entire world eats nearly everyday cause such a ruckus? Well, potatoes as we consume them are generally not toxic. However, old potatoes that have started turning green start to produce a toxin called Solanine. Generally, people feel that it is a waste to throw away food and may possibly eat a potato that has slightly turned green, but eating too many of these could possibly destroy your digestive system!

A study evaluating the toxicity of solanine found that when rabbits were administered solanine, they encountered breathing difficulties and partial paralysis of limbs. Some were eventually found to be dead.  The results of this study highlight how important it is to be mindful of any leftover potatoes that have started turning green or even started budding; it is safer to throw these away rather than risk your personal health just to save a few dollars.

It is very important that more people be informed about this because almost every household in North America consumes potatoes and young children, who are more susceptible to lower doses of toxins are at risk here. Unknowing parents could possibly cook up some greening spuds which, at lower doses may not affect them but could possibly cause their children to fall severely ill. 

So, the next time you find a potato that has been left for too long, despite how hungry or strapped for cash you are, please remember that you risk paying a much higher price for eating it than you would throwing it away. However, why should I pick on the potato only? Below is a video showing other commonly consumed items that pose just as much, if not more of a risk than the potato.

Eating Turkey Makes You Sleepy: True or False?

Many of us have probably heard or even experienced the famous phenomenon known as food coma. If you have no idea what food coma is, you most probably have experienced it before unknowingly. Food coma is a state of lethargy or sleepiness experienced after consuming a large portion of food. Despite its informal name, it is a medically recognized condition called post-prandial comnolence.

Food coma generally hits harder at the most festive times of the year- the holiday seasons. The thanksgiving turkey is no exception. You stack your plates with turkey, sweet potatoes, dressing, cranberries and all the other old-fashioned foods, then fill your stomach up to the brim. Then, of course, you go for a second, then third round. It’s the holiday seasons after all. Not long after, you start to feel lethargic, energy-less and sleepy. Unknowingly, you have fallen into the food-coma trap.

For many years, urban myths have blamed the turkey for the main cause of the sleepiness. But is the turkey really to be blamed?

Where did the myth come from?  Many of you might have heard about the amino acid called tryptophan. Tryptophan is one of the components of the hormone serotonin. Serotonin is converted to the sleep-inducing hormone melatonin. Without melatonin, we will all be always wide awake. This chemical is essential in our body to give us enough rest at night for proper bodily functions. Hence, yes, tryptophan is an essential chemical in our body. However, our body does not produce tryptophan. Tryptophan is obtained by our body from the food we eat.

The tryptophan we ingest competes with other amino acids in our body to enter our brain through the blood-brain barrier. The blood-brain barrier is an interface that separates the brain from the rest of the body. It protects the brain from harmful chemicals that enters the body by filtering them. The blood-brain barrier will only allow certain chemicals to enter the brain. Only a portion of the tryptophan we ingest successfully enters our brain. Most of them are broken down in our liver. The myth that turkeys make us sleepy began when tryptophan were found in turkey meat.

So, do turkeys make us sleepy? The answer to this question is- yes and no. Turkey meat contains tryptophan-yes. However, according to Standford neuroimmunologist Lawrence Steinman, MD, the levels of tryptophan  in turkey “is not higher than in most other muscle tissue from other animals, more commonly known as meats”. It is not the turkey that makes us sleepy but it is the enormous amounts of carbohydrates and often alcohol consumed on the holiday seasons.

Carbohydrates such as the dressing or mashed potatoes induces the release of insulin into the bloodstream compared to other amino acids present. As a result, higher levels of tryptophan are concentrated at the brain-blood barrier.

In conclusion, it is not the turkey that makes you sleepy after Thanksgiving. So, take a quick nap on Thanksgiving, but be sure to wake up in time for the dishes!
