Protein
After Exercise, we should take in high quality protein. Protein is essential for life and is a major part of the body. Every activity in life damages muscle cells - the more strenuous the activity or the exercise, the more damage that occurs. Adequate, high quality protein assists muscle cells in repairing themselves. During digestion, proteins are broken down into smaller units called amino acids. There are 20 different amino acids which can be combined to make many different proteins. Our bodies can make proteins from amino acids, but we are unable to produce nine of the amino acids – the essential amino acids – and these need to be supplied by the diet. Only some foods – the complete protein foods – contain all the essential amino acids and are shown in the following table.
Complete protein foods
| |
Milk and dairy products |
| |
Eggs |
| |
Fish |
| |
Meat and poultry |
| |
Corn plus peas or beans |
| |
Rice plus beans |

Lentils plus bread |
Only animal sources contain all the essential amino acids, but by combining different plant proteins you can also make complete protein foods.
