HOW LONG THE ENERGY LASTS!

SUGARWhat do you eat at break / lunch?

How does that make you feel an hour later?

What could you change about your snack / meal to help you avoid a ‘SUGAR CRASH’?

eSUGARWhy is too much sugar bad?

Sugar (sucrose) is calorie dense, meaning that the pay off of energy is quite low compared to the calorie level.

Eating high calorie food leads to weight gain.

Low energy makes it harder to burn the calories off.

Sugar feeds bacteria in the mouth, if not cleaned properly could lead to tooth decay.

(HIDDEN)SUGARWhat do people mean by hidden sugar?

Sugar is hidden in many ways – normally the label: ‘NO ADDED SUGAR’ is used to confuses consumers.

Many consumers do not realise that certain foods contain natural sugars.

SWEETENERS

Sweeteners are artificial sugars or sugars isolated from plant proteins.

Some sweeteners (Thaumatin) can be up to 2000 times more potent than sugar (sucrose).

What are Sweeteners?

Aspartame is a sweetener made from Aspartate, Phenylalanine and

Methanol.

Aspartate or Aspartic acid – comes from asparagine which in

itself has been isolated from asparagus

Discovery of PKUA Norwegian doctor called

Folling discovered a few

of his mentally disabled patient

smelt very similar.

He isolated the odour’s cause to being the high

amounts of phenylalanine in

the blood and Urine

This is all caused by a lack of phenylalanine hydroxylase, the enzyme

responsible for processing phenylalanine.

Aka Phenylketonuria

Phenylalanine is an essential amino

acid.

It is also an important chemical that helps brain

function.

Phenylalanine

Deficiencies can cause symptoms of depression, and problems with the

brain and nervous system.

People are born with PKU and have to limit protein their diets from birth,

as nearly all proteins contain phenylalanine.

Babies are given special milk.

Because of how dangerous Phenylalanine is to PKU sufferers, the government past legislation in the

“UK in 1982 following the review of its safety by the UK's Committee on Toxicity, Consumer Products

and the Environment (COT)”

Legislation

SweetenersCreate a quick info leaflet telling people about PKU

(phenylketonuria) and how its passed on.

Or write a quick paragraph saying why someone

suffering from PKU can’t drink fizzy drinks

containing sweeteners such as Aspartame
