I beg to differ on this statement as a general concept. As far as my experience goes (I have a bit having known a few chemists and my brother has been heavily involved at both research and corporate level for 20 years) this industry could care less about its patients. They care about getting people onto drugs, keeping them on drugs and making money. You might find a few idealists in research and whatever but when it comes down to it as long as you're buying their drugs they're happy and they're sure as sh!t not going to listen to anyone that tells them that you can control an illness through diet, or whatever better than you can with their synthetic drugs. If this wasn't the case the single diagnosis for ulcerative colitis wouldn't be an expensive, largely ineffectual drug which produces side effects likely to require the use of further drugs. How many people do you see taking a cocktail of prescribed medicine these days?
Here's another story actually. My dog suffered from hot spots and early stage arthritis. Having done a bit of looking into it I found a company that addressed these exact problems through supplements because commercial dog food doesn't give dogs the enzymes they need to properly breakdown their food and regulate other bodily functions. They're used to getting these enzymes in the food their prey eats, like grasses and weeds. The simple solution to this problem is to feed your dog alfalfa minced up. We've been doing this for 5 years (the dog is 9) and he's been basically free of these symptoms since. This natural treatment, if given to all dogs routinely would clear up any number of complaints. How likely do you think it is that the animal food and medicine industries will start researching this, and then if it's found to be beneficial start telling people not to feed their pets commercial food, including the 'science approved' types?
