CARBS AND PROTEIN

CLASSIFICATION OF PROTEIN

• First class protein usually comes from animals ( red meat,chicken,fish,eggs,milk etc)
• Second class protein usually comes from plants (lentils,pasta,nut,brown bread)

AMINO ACIDS

• There are two types of Amino acids Essential and Non-Essentials amino acids
• Essential amino acids must be obtained from food
• Non-essential amino acids are made by the body
• First class or HBV (high biological value)protein contain most essential amino acids
• Second class or LBV(low biological value)protein may not contain all essential amino acids

THE FUNCTIONS OF PROTEIN

• Growth of the body
• Repair of worn out and damaged cells(when you cut yourself)
• Gives us heat and energy
• Makes enzymes,hormones and antibodies

RDA(recommended daily allowance)

CLASSIFICATION OF CARBOHYDRATES

• Sugars:honey,fruit,ice-cream ,gluecose
• Starches:bread,breakfast cereals,pasta,potatoe,root veg,beans,peas,lentils etc
• Fibre rich foods:Brown bread,brown rice,fruit&veg etc

FUNCTIONS OF CARBOHYDRATES

• Provides heat and energy
• Fibre rich carbs fill you up
• Fibre helps prevent and stop constipation and other bowl problems

TO INCREASE FIBRE

• Eat more brown bread and brown rice instead of white
• Eat more fresh fruit and veg
• Eat high fibre breakfast cereals such as bran flakes

REFINED CARBS

• White flour is an example of a refined cereal
• Whole grain cereals are better for the body because they contain fibre
• The fibre is not digested but It obsorbs water which helps move foods along the digestive system
• Muscular contractions called peristalsis push the food along the intestine
• When cereals are refined fibre is removed
