Seeing your favorite dish can initiate neural activity in your brain which is quite similar to the activity seen in addicts on the sight of cocaine. This is because certain foods have addictive properties.
Certain foods can initiate neural activity similar to that seen in addictsFood addiction may be one of the causes behind the difficulty experienced in losing weight, according to Ashley Gearhardt of Yale University, Connecticut.
In a report published in the Archives of General Psychiatry, Gearhardt and her colleagues have studied the response of brain in response to visual stimulation by mouth watering food. The brain activity was compared with the help of functional magnetic resonance imaging after the women taking part in the study were offered a chocolate milkshake or a tasteless solution. Around 48 women ranging from lean to obese were part of the study. It was seen that the sight of a tasty milkshake activated the anterior cingulate cortex and the medial orbito-frontal cortex in the brain. These are the same areas which show an enhanced activity in the brain of an addict after seeing drugs. This activity was even more predominant in women having an addiction for a particular food.
One of the important conclusions of this study is that people may be driven to compulsive food consumption because of the addictive qualities of certain foods. This, in turn, may be a major reason contributing to obesity. Also, people who are already obese, may find it difficult to shed weight as they are addicted to certain foods and find it hard to keep away from them.
Food companies may be deliberately designing foods to make them addictiveObesity, along with the plethora of diseases that it causes, like cardiovascular diseases, diabetes, hypertension and cancer, etc has been on a rise ever since processed, packaged and junk food have become so much a part of our lives. The food companies spend a large part of their budgets on advertising with the sole aim of making us believe that their food is healthy.
Now, many experts feel that the food companies may be deliberately designing foods to make them addictive. These foods contain a lot of refined carbohydrates, trans fat, cholesterol, dietary omega-6 fatty acids, salt and many artificial chemicals, dyes and preservatives. They may be engineered to activate our taste buds and certain areas of brain, so as to make them addictive.
These food companies have been luring unsuspecting customers, especially children, through billboards and electronic media, showcasing their tempting treats.
It is only now that we have come to know about the addictive properties of these foods. We now know that the development and maintenance of obesity may be partly due to an addictive process. This process leads to an elevated activation of the neuronal regions of brain associated with reward circuitry in response to tempting food, and a decrease in the neuronal activity of the inhibitory regions of brain in response to excessive food intake.
Realizing the big challenge that obesity poses to the health care system of the U.S., it may soon be mandatory for all restaurants to add calorie counts to their menus.
