Dopamine, Food and Drugs Part 3
In an animal study with monkeys and cocaine, it was reported that monkeys placed in a group setting [received more attention, more grooming and more access to food and treats] had more D2 dopamine receptors and were less interested in self-administering cocaine. The monkeys housed in individual cages, had a reduction of D 2 dopamine receptors and they increased their cocaine use. This study suggested many things. Perhaps, one’s environment is an important variable for increasing or decreasing D 2 dopamine receptors. Increasing stress in humans results in more humans with addictive behaviors. Not surprisingly, our food industry produces high-fat sugary foods. Further, these cheap calorie dense foods are highly rewarding. In essence, our caloric modern foods and easily available potent recreational drugs, activate our reward circuits. These quick fixes modify the neurotransmitter in the brain and enhance motivation in the directions of addictive, compulsive and consumption behavior. It’s no wonder that advertising and its subliminal messages targets our drug addicted and obese individuals. These folks are clearly susceptible to such messages with their impaired deficits in critical thinking and lack of impulse control. Perhaps one reason we have evolved employing 2 feet is for locomotion. Prehistoric man was able to run down his four-legged dinner. The biological dynamics, and mechanisms of 2 feet are vastly superior to 4 feet. This coupled with our prefrontal cortex of the human brain gives us the edge over our animal nature. Unfortunately, the impulsivity, irrationality, and amoral behavior in man, interferes with maximizing potential for self-good. If you doubt or object to what I’m saying, step on a scale, look in the mirror and peek into your medicine cabinet. Don’t use your brain to falsify the reality. Those quick looks will provide insight about your D 2 dopamine ratio. Do we blame our brain, our economic, political, and religious institutions for the lack of satisfaction and destructiveness? Are our institutions failing mankind? Is the nature of man, the real problem? Or, is it the interaction of man and his institutions? In the meantime, one of my NFL friends said, “Keep moving.” Of course, movement is only part of the story. Do not forget, you are what you eat and you eat what you are. Sad, but true. Pursuing happiness?
