When I first tried these snack bars, I was in love! They tasted like a normal candy bar and I couldn't beleive it! However, I noticed as time went by that after eating one, my stomach would hurt a bit. I'm not sure, but I think my stomach ache was due to the ingredient, malytol (sp?) that is often found in such protein bars. If you don't have this reaction, I highly recommend these bars. If so, you may want to stay away as I do.
