- Carbohydrate
- Deficiency
- Lack of energy, tiredness and fatigue
- If insufficient carbohydrates have been eaten, glucose levels in the blood drop meaning that body cells will lack energy
- If this situation continues, the body will use energy stored in fat cells so the person loses weight
- If insufficient carbohydrates have been eaten, glucose levels in the blood drop meaning that body cells will lack energy
- Weight loss
- If this situation continues, the body will use energy stored in fat cells so the person loses weight
- Severe weakness
- If situation still continues, the body will break down protein in the muscles for energy to power the brain and heart

- Lack of energy, tiredness and fatigue
- Food Sources
- Complex Carbohydrate: Polysaccharides
- Starch: cereals, potatoes, seeds, quinoa
- Pectin: some fruits & some root veg e.g. oranges & carrots
- Dextrin: formed when starchy foods are toasted or baked e.g. toast
- NSP / Dietary Fibre: wholegrain cereals, fruits
- Sugars: Monosaccharides (one sugar molecule)
- Glucose: Ripe fruits & veg. Available in tablets.
- Fructose: fruits, veg and honey
- Galactose: milk from mammals
- Sugars: Disaccharides (two sugar molecules)
- Maltose: cereals such as barley
- Sucrose: from sugar cane / beet
- Lactose: Milk from mammals
- Complex Carbohydrate: Polysaccharides
- Excess
- Excess carbohydrates will be stored as fat which could lead to obesity
- Refined / Processed carbohydrates (e.g. sugary foods) are quickly absorbed by the body
- Causes rapid rise in blood sugar levels
- Can put stress on the pancreas which develops insulin
- Could result in Type 2 Diabetes
- Eating certain types of sugars can cause tooth decay
- What is it?
- A macronutrient
- Needed by all animals
- Plants make it using photosynthesis
- Two main functions
- Main energy source in our diet
- Helps the body get rid of waste products
- NSP is a type of carb that helps produce soft bulky faeces that are easy to pass out of our body
- A macronutrient
- DRVs
- 50% of food energy per day
- Free sugars (a.k.a. added sugars) no more than 5% of food energy per day
- Non-starch polysaccharide / dietary fibre varies per age group
- Adults - at least 30g per day
- 2-5 years - 15g/day
- 5-11 years - 20g/day
- 11-16 years - 25g/day
- 16-18 years - 30g/day
- Deficiency
