Say you didnt get your nutrients from the food that you eat for..say a week? I mean not like on that movie supersize me where he only eats mcdonalds for a month, but if you actually got none of these nutrients, providing that you could live for a week without them. Is that possible? I mean, is it possible to live for a week without any nutrients at all going into your body? Another question, if it happens to be the answer to my first question that you cant live without nutrients for a week, how are these nutrients or why are these nutrients so important to our body? Is there a certain nutrient or are there specific nutrients that give us the ability to live? And if you possibly could live without nutrients for a week, then does that mean that it takes time for the nutrients you consume to become 'active' in your body?
