Bottom line...where as "energy bars" promise heaps, the only advantage over the more generic snacks foods (see the last few entries) is the nutritional values (vitamins an minerals).  That being the case, I will NOT be relying on these very often...and even then mostly for some diversity in trail foods or when I don't think i'm getting my vitamins (i.e. bonking).

Power Bars:  The Standard.  Will alwasy make do in a pinch. Personally I don't find the taste so awful although the texture is rather grainy and requires a good amount of water to wash it down. $1.09

Power Bars Protein Plus:  Texture too tough and the outside flavoring/coating melts too easily making a mess.  High protein not needed as much as carbs anyway.  ~$1.50

Twinlab Ironman Hi Performance:  230 calories. 25g carbs (22g sugars) HORRIBLE tasting.  I tried the Coffee Crunch.  A better name would be soggy dirt. $0.89

Twinlab Soy Sensations (Lemon Cake): 180 calories. 23g carbs (14g sugars) I didn't enjoy this flavor.  $.057

Coach's Iced Energy Bar:  220 calories.  35g carbs (23g sugars) I liked this one.  Nice texture and just the right amount of sweetness.  A winner! $0.89

Tiger's Milk:  140 calories 18g carbs (14g sugars) Another standard.  Not the best tasting, but definitely not the worst.  Good for a change if nothing else.  A little low on calories but the price makes up for it. $.49

CLIF Luna:  180 calories. 26g carbs (14g sugars) Strange Texture.  Don't think I liked it much.  (Tried the Lemonzest flavor) $1.09

MET-Rx (Chocolate Cookie Dough): 340 calories 50g carbs (29g sugars).  I couldn't force myself to eat any more than half of this one.  Absolutely disgusting.  Probably an excellent choice as emergency food for this reason.  $2.29

Nature's Valley Granola: 90 calories 15g carbs (6g sugars) Another standard fare. Readily available the world around and the cheapest foodstuff listed.  A definite staple.  $0.10

Austin Crackers: 190 calories 23g carbs (3g sugars).  Grocery store/snack classic.  $0.17

Poptarts: 200 calories 35g carbs (3g sugars).  Breakfast/starter.  Tastes *wonderful* Perenial Favorite. $0.16

Nutri Grain Cereal Bars: 140 calories 27g carbs (13g sugars) More breakfast type stuff.  How can you go wrong with fruity, chewy, granola bars?   $0.22
