Functional foods are foods which provide fuel or architecture to different organs, systems or tissues of the body.
Functional foods can help to enhance the function of different organs or tissues and aid to heal any abnormalities.
Just like a house is built with different materials ( i.e concrete slab for foundations or tin for the roof) different nutrients provide this structural support for the body ( i.e protein and fat for liver structure).
Every organ requires a different set of nutrients to ensure it is running smoothly. Weight loss, thyroid conditions, osteoarthritis, irritable bowel syndrome all involve a number or organs or systems which may be lacking in some of these priority nutrients.
You can help your body to heal itself.
