Chocolate Overdose

It is common knowledge that you should not feed dogs and cats chocolate as it is poisonous to them. This is because chocolate contains a substance called theobromine. The name theobromine comes from the Greek words theo (“god”) and broma (“food”), thus meaning “food of the gods”.

Cats and dogs metabolise this chemical very slowly, so they can easily overdose on it. Theobromine poisoning causes vomiting and diarrhoea initially, then progresses to cause hyperactivity, cardiac arrhythmias (irregular heartbeats), seizures, internal bleeding, cardiac arrest, respiratory failure and eventually death. Although cats and dogs have the same metabolism rate of theobromine, there are far less cases of cats overdosing on it as they do not have sweet taste receptors and do not particularly like the taste of chocolate.

Luckily for us, the human body can metabolise theobromine much more efficiently and we are much less likely to get theobromine poisoning (although it is still possible if you eat too much of it). Although it is weaker, theobromine behaves similarly to caffeine in the human body. It stimulates the heart to beat faster, relaxes the blood vessels, reduces blood pressure and stimulates your nervous system to decrease your tiredness and give you a “buzz”.

The effects are potent enough that there is some evidence that eating dark chocolate (which has a higher theobromine content) regularly can reduce your risk of heart disease. However, this is counterbalanced by the negative health effects of sugar and fat found in chocolate. That being said, a small amount of chocolate every now and then not only has a positive effect on your heart, but is a great medicine for your exhausted mind and soul.

Sweet Tooth

It is interesting to see how people tend to use taste-related metaphors to describe other people. If a person is hostile or spiteful, we describe them as “bitter”. If a person is sullen and gloomy, we say they are “sour”. Perhaps the most extensively used taste is “sweetness”. People have a tendency of calling their loved ones sweet-related names, such as “honey”, “sweetie”, “sugar” or “sweetheart”. This is directly reflected in the tradition of giving chocolate to a loved one on Valentine’s Day. Quite obviously, this is because we find sweetness the most palatable taste and something that is nice. On a related note, could there be a relationship between sweetness and personalities?

A group of psychologists decided to study whether people who like sweet foods, or “sweet tooth”s, have a certain personality trait or not. They did a survey where participants were asked what foods they liked most out of a list of 50 foods covering five tastes (sweet, sour, bitter, salty, spicy). They also answered questions that gave an indication of their agreeableness (one of the five components of OCEAN personality traits). The psychologists then analysed whether there was an association between sweet tooths and agreeableness. Interestingly, a direct correlation was found between a liking of sweets and higher levels of agreeableness. This suggested that people who like sweet things tend to be more friendly, cooperative and compassionate.

But is the cause-and-effect relationship so simple? Could it be that sweet things cause people to be nicer? In a separate experiment, participants were randomly given a sweet food (chocolate), a not-sweet food (cracker) or no food. They were then asked to volunteer their time to help someone. It was found that those who were given something sweet were more willing to help another person compared to the other two groups.

This makes logical sense as eating sweets such as chocolate causes your brain to release a flood of hormones such as endorphin and serotonin from the absolute pleasure of the experience. These hormones make us feel happy, blissful and in love, which in turn make us more agreeable and willing to cooperate.

Although sweetness has numerous negative effects on the body such as weight gain and diabetes, there is no doubt that it is greatly beneficial for your mental health. If there is a bitter person around you, give them a good dose of chocolate to help them develop a sweeter personality. Or perhaps all they need is a sweet romance.

Valentine’s Day

Valentine’s day is the one day put aside every year, on the 14th of February, to celebrate the love between a couple. It is a rather controversial(?) holiday with many people contesting that it is the result of chocolate and flower companies conspiring to increase sales and that people should love equally on every day. The day is full of hearts and cupids and chocolate, making it the perfect day for couples to show off to the world just how much they adore each other, while single people put up a nonchalant face while desperately trying to distract themselves from the fact that they alone (there is also a statistic that states suicide rates peak during Valentine’s day).

February 14th was not always associated with romantic love. Originally it was a day honouring Saint Valentine of Rome (it is debated whether day honours him or another Saint Valentine – Valentine of Terni). In 1st century Rome, it was illegal for Christians to marry. Saint Valentine secretly performed weddings for Christians under threat of death (helping Christians was illegal too). He was eventually caught, imprisoned, tortured and killed.

As one can see, the story (and its ending) is not the most romantic one and Valentine was honoured for helping Christians rather than being involved in marrying people. It appears that the romantic association started around the 14th century in Parlement of Foules by Chaucer. Up until the 19th century, the only custom for Valentine’s Day was the giving of cards (or “valentines”) between loved ones. It was in the mid-1900’s when the practice of giving roses and chocolates arose (most likely due to advertising campaigns by companies for the commercialisation of the day), with the diamond industry promoting a custom of giving jewellery on Valentine’s Day.

Another not-so-lovely story related to Valentine’s Day is the infamous Saint Valentine’s Day Massacre of Chicago in 1929. In a conflict related to gangs and bootlegging, the South Side Italian gang led by Al Capone initiated a deadly attack resulting in the death of seven deaths.

Eskimo Pie

In 1920, a candy store owner by the name of Christian Kent Nelson had a customer. The customer was a young boy who was torn between buying ice cream or chocolate, with only enough money to buy one. Nelson noticed this and decided there was only way to solve this conundrum.

He created a bar of ice cream coated by melted chocolate, which he called “I-Scream Bars”, now known as Eskimo Pies. It was an instant hit as children could buy both chocolate and ice cream for the same amount of money.
