Diet and nutrition

It irritates me to think of the fact that many people today are more concerned with what they want rather than what they need.One may want to drink a glass of chilled beer whearas one needs fruits.The irony of this is that the body's internal environment will always pick what it needs from the bulk of junks we throw in.
Diet is that thing you want to eat (probably because of its taste) but nutrition is that thing your body needs to function effectively.There is no strict rules here because individuals vary from the other so why dont you examine yourself (a health personnel can help you) and start eating aright; tomorrow may be too late my dear.
