Favadi, unfortunately, the drug companies have the money to pay for research- but getting (non drug company) funding to show non drug interventions prevent, cure or control is difficult, very difficult.
I had heard the coeliac pill one before, btw, it wont be the 1% of the population who are diagnosed coeliacs who will end up being prescribed this, it will be the 30-40% of the population who are either ceoliac and don't know it, are in the process of developing it (can take decades), or who have antibodies at a level currently described as "negative", the diagnostic boundaries will be changed... and it is just as crazy as the situation with diabetes...
Rather than being given dietary advice to stop eating the thing that has making them ill (grains, carbohydrate) and return to a more natural clean diet, people are given medication to reduce their symptoms so that they can continue as before, and eat "normal" food like everyone else, maybe will appalling consequences for their long term health.
I read a pretty horrifying report a few months ago, blood tests on thousands of American teenagers showed that just under half fitted the diagnostic criteria for diabetes or prediabetis!
It is hard to over emphasise how abnormal this is in any kind of animal, having that level of chronic illness (showing the whole metabolic system is in disarray) in the young of a species, in this case, humans, shows something is very, very wrong indeed.
The response has been a big push to get pre diabetics onto drugs to delay the development of full diabetes, while continuing to eat "normal" food. 50-60% healthy grains! Oh yes!
Unfortunately, few realise, maybe don't want too either, how they are manipulated large food corporations and by bad pharma. Ben goldacre's book of the same name is an eyeopener!!!
