The Third Nutrient….what does it do?

28/04/2009 by admin.

We all hear about the 3 main nutrients of carbohydrates, protein and fats.  We also know they are all important to help us function properly but do we really know much about protein? Here is a summary of some of the key roles provided by protein. 

• Proteins are involved in muscle contraction so are particularly important for those of us that are active.

• We have structural proteins such as ligaments and tendons at the end of muscles which help with movement. 

• Our hair and nails are also formed with structural proteins.  The condition of your hair and nails can be a good indication of the quality of your diet.

• Proteins are antibodies which fight infection.

• Proteins are messengers which coordinate certain activities within our bodies that help to control functions such as blood sugar levels and muscle growth.

• Enzymes involved in various chemical reactions in the body are proteins, an example of this is the digestive function.
