Hmm after reading the responses to the OPs question, none really seem to answer his question....yes beef jerky is a good snack but when buying in a regular store, make sure you look at the ingredients and nutritional info. Jerky on average contains decent amounts of protein, usually 95-98% fat free, and typically has low carbs. One thing to keep in mind is that beef jerky has a decent amount of salt if this is a concern to your health and be sure to watch that not much sugar is added as some manufactures tend to add upwards of 10 grams of sugar per serving.
I used to eat jerky constantly but I find that it makes my teeth extra sensitive and gets lodged deep between my teeth, often where flossing cannot be effective, additionally, unless you chew jerky for about 30-40 seconds each bite, your body will take quite a bit of time to digest it.
