A lot depends on the type of frog you have. I wouldn't feed most tree or aquatic frogs a lot of mealworms, but I would be comfortable with feeding more to certain toad species. For example studies have shown that as much as 70% of some north american toads diets consist of hard shelled prey like beatles. Obviously a species that eats so much large, hard shelled prey in the wild is going to be a lot less likely to have digestion problems than species that tend to eat a larger % of smaller or soft bodied prey. Of course nothing should be fed to exclusion. In years past studies have shown even hard shelled adapted species tend to build up excessive fat deposits and have a shorter life expectancy if fed exclusively on meal worms(as was common many years ago). In short, mealworms are a perfectly acceptable food item for many amphibians as long as they are not fed exclusively and only make up a portion of a varied diet.
