Nutrition: Calorie Count Keeps Track- Why Shouldn't You?

I have mentioned a few times on here that I like to use Calorie Count (www.caloriecount.about.com).  Well, one thing this site is good at is keeping track of certain nutrients.  Here are the items it tracks (besides calories):

1) Carbohydrates
2) Protein
3) Fats
4) Saturated Fats
5) Cholesterol
6) Sodium
7) Fiber
8) Vitamin A
9) Vitamin C
10) Calcium
11) Iron
12) Potassium

Well, needless to say, I don't do very well on most of these things.  So I wanted to do a little research that will help me make better choices at the grocery store the next time I go shopping.

Here is what I found is the recommended daily intake of each of the 12:

1) Carbohydrates: If you are trying to lose body fat, 20-70 grams of carbs per day are recommended, depending on your level of activity.

2) Protein:
