Food Addiction and Conditioned Taste Preference
With obesity as a growing epidemic in the United States and fast food chains available on every corner, food addiction has become a prevalent problem in our country. Foods that contain salt and sugar are being consumed at unhealthy amounts and due to its addictive sensation, it is imperative to comprehend the relationship between taste preferences and food addiction.
An experiment that examined the influence of the opioid system in expressing and acquiring sugar-related conditioned place preference tests, studied whether naltrexone (an opioid antagonist that is most commonly used to counteract drug and alcohol addiction) influenced flavor preferences in rats. (Delamator et al. 1999) The hypothesis of this article is that CPPs can be used with natural reinforcers and that the opioid system plays a significant role in this learning.
Another experiment compared the affects of opioid receptor subtypes while rats were injected with either saccharine solution and maltose dextrin solution, to figure out which receptors were involved in regulating the ingestion of substances with preferred tastes. (Beczkowska et al. 1993) The hypothesis of the experiment is that the opioid system regulates sugar intake since naloxone and natltrexone reduce intake in rats.
The third experiment …
I chose this topic to get a more concise understanding of the relationship between food addiction and conditioned place preferences and to be able to learn just how drugs can be used to alter these states. The purpose of this paper is to better understand the relations between food addiction and conditioned taste preference by examining and interpreting experiments that have been conducted by other neuroscientist...

... that delta 2 receptors are involved in the regulation of hedonic orosensory signals, meaning how pleasurable taste preferences are.

Opioid Receptors Alter Sucrose (Methods)
Procedure
This study compares the effectiveness of centrally-administered opioid receptor subtype antagonists to inhibit intake of either a 10% sucrose solution or water after being dehydrated for 24 hours. The rats used for this experiment were kept on a 12h light and dark cycle and were housed individually. They underwent surgery to insert a stainless stell guide cannula above the left lateral ventral. After having a week to recover, they were water deprived for 24 hours and given access to10% sucrose solution in a tube and tested on three occasions … The rats received between 3 and 9 microinjections at weekly intervals in different groups.bgvfcdxszfgh
