Why So Many People Eat Junk Food Essay

If you’re a junk food junkie or have a monster sweet tooth, you could be doing damage to your health. Fast food and sweets are typically light on essential nutrients and heavy on ingredients that could lead to health problems. Eating too many fatty and sugary foods has been linked to everything from obesity to tooth decay and chronic diseases that can shorten your life.

Weight Gain

Fast food typically contains high amounts of saturated fats, trans fats, sodium, and many more calories than most people should consume in one meal. A 2008 Harvard review of 16 studies reported by PubMed concluded that fast food consumption may be worsening America’s obesity epidemic. Sweet foods and sweetened drinks are also high in sugar that can pack on pounds. A separate review of 30 studies published in the “American Journal of Clinical Nutrition” in 2006 concluded that high consumption of sugary drinks contributes to weight gain and obesity.

Diabetes and Heart Disease

The excessive amounts of sodium in fast food can lead to elevated blood pressure. High blood pressure is a risk factor for heart disease and stroke. A diet high in saturated fat and trans fats also increases the risk of these diseases by clogging the arteries. The risk of stroke may be related to the number of fast food establishments in a neighborhood, according to a study published in the "Annals of Neurology" in August 2009. In the study of a neighborhood in Nueces County, Texas, the risk of stroke among residents increased 1 percent for every fast food restaurant in the neighborhood. Additionally, a paper published in “Physiology & Behavior” in 2010 reported that large epidemiology studies show an association between the sugar-sweetened beverages sold at many fast food establishments and the risk of Type 2 diabetes as well as heart disease.

Tooth Decay

The sugar in sweets and sweetened beverages encourages bacteria to produce acid that eats away at tooth enamel, eventually leading to tooth decay. Every time bacteria comes in contact with sugar or starch in the mouth, acid is produced that attacks the teeth for 20 minutes or more, according to the American Dental Association. Some soft drinks contain a whopping 11 teaspoons of sugar in a single serving. The ADA recommends limiting sweets and sugary drinks, brushing twice a day, flossing once daily and having regular dental checkups.


Fast food can be healthy if you choose wisely. The American Heart Association suggests visiting the websites of fast food chains beforehand to identify the healthiest choices. Skip the fries and onion rings, which are usually deep-fried. The association recommends grilled chicken sandwiches, which are often healthier and leaner than burgers. Additionally, the Academy of Nutrition and Dietetics suggests splitting your order with a companion to cut the calories you consume and evaluating whether a “value meal” is really a value before ordering. If you don’t need the extra food or a super-sized portion, it might not be a good value for your wallet or your body.

Why So Many People Eat Fast Food?

Nowadays, time seems to be an important factor for people around the world. Today people, especially in Bangkok,the capital city of Thailand, have to wake up and go out early to study or work, so they have to avoid any traffic jams.
