United States raw milk debate concluded that "raw milk poses a realistic health threat due to a possible contamination with human pathogens. It is therefore strongly recommended that milk should be heated before consumption. With the exception of an altered organoleptic [flavor] profile, heating (in particularly ultra high temperature and similar treatments) will not substantially change the nutritional value of raw milk or other benefits associated with raw milk consumption." Pasteurization opponents say that raw milk contains bacteria beneficial to the human digestive system, but pasteurization is not selective and affects all bacteria whether beneficial or infectious. These bacteria include species considered to be probiotics,
Conflict procedure and contingent electric foot shocks." In order to operate the experiment, researchers build anxiety by electrical shocks on rats gradually through a training in serval week. This process was what researchers called Conflict Procedure. Conflict procedure The conflict procedure is an experiment often used in scientific research to quantify anxiety levels by measuring changes in punished/unpunished responding. It is often used to screen drugs for their potential to inhibit anxiety (anxiolytic potential). Some researchers from France have conducted an experiment on "Effects of Chronic Antidepressants in an Operant Conflict Procedure of Anxiety in the rat (1998)", "the aim of their
