Diet
Healthy balanced diet has the right balance of food types;
- Carbohydrates - a source of energy for life processes.
- Protein - growth and repair - building cells.
- Fat - a source of energy for life processes: fats are also needed to make cell membranes and to insulate our bodies.
- Mineral ions and Vitamins - neede in small amounts for healthy functioning of the body.
Inbalanced diets
- Too little food = underweight
- too much food = overweight
A poor diet may also lead to deficiency diseases. For example, little vitamin D in the diet can lead to rickets, which affects the proper growth of the skeleton.
