"The mind is the limit. As long as the mind can envision the fact that you can do something, you can do it, as long as you really believe 100%"
I found this information on one of the websites I browse through everyday, It was at crossfitverve.com. The guys name is Matt Chan he is a CrossFit Games competitor. He did a really good job breaking down different protein bars and giving the nutritional value to them, I thought it was interesting and well worth the read. He also has a great section under "fuel"that provides some really good paleo recipes, you should check it out.

Conclusion:
Tanka Bar
Macro-nutrient information; Protein 7gm, Carbohydrates 7gm, Fat 1.5gm.
Zone: 1P, 0.77C, 1F
1st ingredient: Buffalo
Predominate protein source: Buffalo
Percentage of bar that is sugar: 24%
Top 3 sugar sources: Sugar on the dried cranberries, no other source.
Contains Soy? No

My top three choices:
#1 Tanka; it contains real food, is balanced at 1block, has the lowest sugar % of bar so I will stay satisfied longer with less. I understood all the ingredients on the label. Contained no soy.
#2 Lara bar; I choose this one because it was all real food, with only three ingredients. The fat is nuts and will keep me satisfied. I would however have to have it with a protein source like jerky or the sugar cravings would surely come later in the day with a 62% sugar content. Contained no soy.
#3 Think Thin; I would consider this a 2.5 block snack. It is well balanced and contains a higher amount of whey then soy. They have a lower percentage of sugar content then most of the other bars. Has higher protein content then all the bars without raising the sugar also.
So there is my two cents on how to look at bars. I hope this helps in a pinch!
