Building BLock : Protein
What is protein
Proteins are naturally occurring substances found in animal products and some plant products . Proteins are in every living cell in the body . Our bodies need proteins from the foods we eat to build and maintain bones , muscles , and skin , and for our cells to function .
You need to eat proteins every day , because your body doesn ’ t store them the way it stores fats and carbohydrates . Proteins are found in dairy , meats , fish , eggs , beans , and nuts .
What does protein do ?
Protein provides our body with amino acids . Amino acids are needed for growth . Amino acids also maintain and replace body tissue such as muscles , bones , blood , and body organs .
There are over 20 amino acids , which join together in different ways to make thousands of different proteins . Eleven of these amino acids are made by our bodies and are called ‘ non-essential ’ amino acids . The other nine are called ‘ essential ’ amino acids because you have to get them by eating the right foods .
What foods are a good source of protein ?
The best sources of proteins are lean meats , poultry , fish , eggs , low fat dairy products , nuts , seeds , and legumes like black beans and lentils . Foods that provide all the essential amino acids are called complete proteins . Proteins from animal foods have all the essential amino acids you need . Plant foods have some essential amino acids so they are called incomplete proteins . Incomplete protein sources include nuts , grains , fruits , and vegetables . Therefore it is important for vegetarians to chose meals wisely in order to get all essential amino acids in their daily diet .
