B1b - HUMAN HEALTH AND DIET
Food gives ENERGY and NUTRIENTS
A balanced diet contains carbohydrates, fats, protiens, minerals, vitamins, fibre and water
Carbohydrates: provide energy. Made up of simple sugars. Stored in the liver as glycogen or turned into fat if they are not used.
Fat: provide energy. Stored as adipose tissue under skin and around organs.
Protiens: used for growth and repair. Made up of amino acids. They are not stored.
Minerals: like iron for making haemoglobin in red blood cells
Vitamins: like vitamin C to prevent scurvy
Fibre: for healthy bowels and to prevent constipation
Water: prevents dehydration and to help remove waste
You might alter your diet as a result of:
- Religious beliefs
- Medical issues (food allergies)
- Activity (builders need more calories than office workers)
- Personal choice
healthy body mass = balancing the amount of energy you use with the amount of energy you consume on a daily basis
BMI=Body Mass Index
