Don't worry Helen, I wouldn't dare suggest that you haven't got the best interests of your fish in mind. I've seen quite a few of your fish and I have no doubts about how healthy they are. As you say you balance out their diet very well. I've still got that video of your Paratilapia polleni spawning and there's absolutely nothing wrong with them. We've had a Piranha die over the weekend at the age of 24 which was fed a lot of beefheart for a fair part of it's life. The digestion of a fish like this should be well able to deal with it when prepared properly, but I've also seen some badly mis-shapen Loricariids (amongst others) which have scavenged beefheart fed to other fish in the aquarium. I also remember a necropsy performed on a Steatocranus casuarius from an BCA publication in the 80's where a large piece of beefheart was found to be blocking the intestine. So I still say it needs to be used carefully. So there.
