Hoppity, I am well aware that gluten allergy is not the same thing as an impaction. I was making an analogy that something that is a problem for a very small percentage of the population is no reason for the majority to avoid it out of paranoia. If this person had been feeding mealworms or excessive amounts of pinkies, then diet would have been a major discussion point. People on this forum (in my experience) are not the type to tiptoe around someone's feelings when tough advice can help the frogs. The reason no one else was talking about that is because dubias HAVE NOT been documented to cause impaction.
I think popcorn is a good analogy here. Corn is a common human staple food. Yes, some people (my father for instance, who has had major surgery for diverticulitis and cannot eat small grains) may suffer severe infection, pain, or death from eating it. For these people, there are specialized diets. However, saying that it is bad parenting for someone to buy their child popcorn at a movie because of this is a bit ridiculous.
Roaches have low risk and the reward of a safe, home-bred food supply and added variety to the diet (which nearly everyone will agree is beneficial). If you can find any information that dubia roaches are an unsafe feeder, rather than just personal opinion, I will gladly revise my stance. My frog has neurological issues that seem to affect her GI tract. However, I wouldn't recommend my restrictive and paranoid care routine to others, because it would be completely unnecessary for most frogs.
It is both unfair and inaccurate to compare feeding roaches to sub-par or uncaring husbandry, especially without any hard facts to back it up. Most of the people on this forum do not need someone to speak for their frogs, as they are already providing good care, and are willing to listen to others to keep improving it. Again, I am NOT criticizing your care routine. Just saying, there is no call for accusing everyone who feeds roaches of giving their animals sub-par food, when you have no actual evidence to support this.
