Some people with liver disease must eat a special diet. This diet helps the liver function and protects it from working too hard. Proteins normally help the body repair tissue. They also prevent fatty buildup and damage to the liver cells.
Advise is a verb, and advice is a noun. So advice is what is given, while the act of giving advice is called advising (or to advise).
As I see it, 'advise' in the formal style takes on the meaning of 'inform', so in a slightly changed context it might mean 'Please inform (us) if/when you have received our letter.'. Nov 22 2005 07:48:38.
