Our bodies use the food that we eat and drink as fuel, breaking them down for energy.
- Fats are broken down into fatty acids
- Carbohydrates are broken down into small, sugar units, glucose, fructose and galactose.
- Protein is broken down into amino acids
- Alcohol is absorbed directly into the blood
All the above produce energy.
Carbohydrates and alcohol are used mainly for energy production in the short time, whilst fats are used for long term energy store. Contrastingly Proteins are used to produce energy when carbohydrate are in short supply or when there use within the body draws to a close.
