Death by Chocolate: The Maths

May 28, 2014

 Choco Yum Yum! Mathspig lervs chocolate. But did you know chocolate can kill you?

Chocolate contains a chemical called Theobromine. This alkaloid ( other alkaloids include cocaine, nicotine, caffeine and strychnine) can kill humans. More info Wired Magazine.

How much chocolate is too much?

Firstly, the darker the chocolate the more Theobromine it contains.

According to About Chemistry:

Based on highest possible toxicity:


wrapper crop 2White Chocolate: insignificant

wrapper crop 3

Milk Chocolate 1-5 g/kg

200gm block = 1 gm per block

……………………………………………………………………………………….

wrapper crop 1Dark Chocolate 10 g/kg

200gm block = 2gm per block

 ..

…………………………………………………….

??????????????????????????????????????Cooking or Baking chocolate* 10-50 g/kg

200mg block = 10 g per block

(* Vetmedicine: Cooking chocolate contains 8-10 times the Theobromine in Milk Chocolate )

According to Wired large doses of theobromine may cause “nausea and anorexia ….. sweating, trembling and severe headache.”

The Royal Society of Chemistry notes that chocolate does not contain caffeine, but theobromine induces similar symptoms.

LD50 for the lethal dose for 50% of the population f or Theobromine is:

1000 mg/kg 0r 1gm/kg of body weight in humans

Death by Chocolate for DOGS

choc wrap 1Chocolate can be fatal to dogs. As dogs are small they can easily eat enough chocolate to kill them. According to The Royal Society of Chemistry

LD50 or Lethal Dose for 50% of the population of dogs for Theobromine is 300 mg/kg or 0.3 gm/kg.

Dogs are susceptible to Chocolate Poisoning because they do not metabolise Theobromine very quickly. In other words, they can gobble down a lot of chocolate (Christmas Day and Valentine’s Day are danger zones for dogs) and the chemical builds up in the body to a lethal dose.
