## Death by Chocolate for DOGS

February 22, 2021#### Chocolate 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

#### The National Geographic has an amazing interactive chart for dog poisoning by chocolate.

## Death by Chocolate for CATS

February 21, 2021#### Chocolate contains a poison called Theobromine.

#### LD50 for Theobromine for cats is 200mg.

#### LD = Lethal Dose. LD50= Lethal Dose for 50% of the population. Cats in this case. This is how poison toxicity is measured.

#### According to The Royal Society of Chemistry, cats are hypersensitive to Theobromine but, as cats cannot taste sweetness, they are rarely poisoned.

## 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:

White Chocolate: insignificant

#### .

#### .

## Milk Chocolate 1-5 g/kg

#### 200gm block = 1 gm per block

……………………………………………………………………………………….

## Dark 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

# 3. Percentage

## Death by Chocolate for DOGS

May 28, 2014#### Chocolate 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.

#### The National Geographic has an amazing interactive chart for dog poisoning by chocolate.

## Death by Chocolate for CATS

May 28, 2014#### Chocolate contains a poison called Theobromine.

#### LD50 for Theobromine for cats is 200mg.

#### LD = Lethal Dose. LD50= Lethal Dose for 50% of the population. This is how poison toxicity is measured.

#### According to The Royal Society of Chemistry, cats are hypersensitive to Theobromine but, as cats cannot taste sweetness, they are rarely poisoned.

## Sweet Tooth Maths 1

March 27, 2013# Good News for Chocoholics

#### To get the right texture Easter Eggs are made from sugar or sucrose and not from corn syrup. But chocolate contain lots and lots of sugar.

#### ………………………………………………..

#### Guylian Sea Shells:

#### Weight Sea Shell: 120 g

#### Weight Sugar: 48g

#### % sugar = 48/120 x 100 = 40%

………………………………………………………………..

………………………………………………………………

#### This is a Guylian Luxury Easter Egg. It can also be used as a designer handbag, I guess.

#### Guylian Easter Eggs:

#### Weight Easter Egg: 100g

#### Weight Sugar: 52g

#### % sugar = 52/100 x 100 = 52%

#### You’ll find nutrition data here.

# Easter Challenge:

#### Here is the largest Chocolate Easter Egg ever.

#### This Giant Egg from the Guinness Book of Records was made in 2005 in Belgium by chocolate maker Guylian.

# Statistics:

#### Height: 8.32 m

#### Weight: 1950 kg chocolate or 4300 lb

#### No. Chocolatiers: 26

#### No. Chocolate bars: 50,000

#### Total time: 525 hrs

# Easter Challenge for Chocoholics

#### The amount of sugar in the giant egg weighs as much as a Fiat Pinto.

## Sweet Tooth Maths 2

March 27, 2013#### Gather round mathpiggies.

#### Today we are going to be Food Scientists; food science needs maths and this food science is important for your health and diet.

#### Before we do the maths we must understand the science of sugar. Here is a simple explanation.

#### In the USA corn, which is 100% glucose, undergoes an industrial process that breaks down the long glucose chains and converts some glucose to fructose because fructose delivers a bigger sweetness hit on your tongue and corn is cheap. The resulting HFCS (high fructose corn syrup) is, on average, 60% fructose.

#### Now we can do the maths.

#### This important information below comes from the Goran Labs

……………………………………………………………………………..

# Food Science Maths

# or

# Fast Food Maths

……………………………………………………………………………..

#### 1. Draw up a bar graph of the weight of sugar(sucrose) and fructose for 8 drinks.

#### 2. Plot the weight of sugar(sucrose) and fructose for 8 drinks on axes.

#### 3. Assuming that 100ml of soft drink weighs 100g – this is realistic- calculate the percentage of sugar(sucrose) and fructose. This exercise is to see if students are paying attention. It is very easy!

#### 4. Drinking too much sugar in any form is not advisable, but fructose in large quantities just adds calories without satisfying your hunger. Which drinks are loaded with fructose?

## Sweet Tooth Maths 3

March 27, 2013#### Food Scientists check to see if the stated sugar content of food equals the actual sugar content. Here is a medium sized Macdonald’s Coke.

#### ………………………………………………

#### The size of a medium sized coke is:

#### 590ml (Australia) containing 55 g sugar.

#### 621 ml (21 fl oz) USA containing 58 g sugar

#### 400ml (UK) with 42 g sugar.
