Lowering Salt in Your Diet. 1  Salt is regulated by FDA as a âgenerally recognized as safeâ (GRAS) ingredient. A GRAS substance is one that has a long history of safe, common use in foods, or that is determined to be safe, for the intended use, based on proven science. These substances need not be approved by FDA prior to being used.
Gastroenterologists are internists who specialize in diseases of the intestines. Gastroenterologists perform most colonoscopies. Other doctors who perform colonoscopies: Colon and rectal surgeons are general surgeons with extra training in the surgical treatment of intestinal and rectal conditions. General surgeons specialize in the surgical treatment of a variety of diseases, disorders and conditions. Some general surgeons focus their practice on the intestinal tract.
I was surprised recently to learn that lots of colonoscopies in the US are not performed by gastroenterologistsâphysicians who, of course, specialize in the diagnosis and treatment of digestive conditions. Primary-care doctors and general surgeons also are doing these vitally important screenings that can detect and save a patient from cancer. Do they do as good a job? Well, a new study compares how good the colonoscopies are when done by these three types of doctorsâand, trust me, the results may influence the type of doctor you choose to perform your next colonoscopy.
