The consumption of fast food has been linked to negative effects on physical and psychological health. Fast food is characterized by high glycemic load and energy densities, which can lead to obesity, digestive problems and depression if consumed in excessive quantities. Increasing rates of obesity and depression in countries such as the United States and the United Kingdom can be attributed to the increase in fast food consumption (Rosenheck 535).

In the United States, the number of fast food restaurants increased dramatically from 30,000 in 1970 to over 233,000 in 2004 (Rosenheck 535). I am convinced that fast food has a negative impact on consumers' physical and emotional well-being. Portions of fast food meals are often much larger than the average calorie intake of homemade food for an adult. This excessive calorie consumption can lead to weight gain. Additionally, fast food restaurants typically serve predetermined portions with a higher calorie content than an average adult should consume. For example, sandwiches at fast food restaurants come in two specific sizes: 12 and 6 inches. Research has shown that women expend 31% more energy and men expend 56% more energy when eating a 6-inch or 12-inch sandwich, respectively (Ledikwe, Ello-Martin, and Rolls 906). Studies of fast food snacks have also revealed that women consume 18% more calories and men consume 37% more calories than their usual energy intake (Ledikwe, Ello-Martin, and Rolls 907). The high energy density of fast food, due to its high fat content, contributes to increasing consumers' calorie intake. Fast food is also full of unhealthy fats. While fats from natural sources are essential for digestion, absorption, and transportation of vitamins and fat-soluble essential elements, fats found in fast foods are primarily saturated fats and trans fats. An adult male should consume no more than 30 g of saturated fat and a woman should consume no more than 20 g, with less than 5 g of trans fat, to maintain good health (Rosenheck 536). However, a single bite of a restaurant burger contains nearly 10 g of saturated fat, exceeding the recommended intake for men. The high fat, salt and sugar content in fast food leads to an increase in harmful bacteria, causing indigestion. Fast foods such as French fries, fried chicken and bread are often cooked in hydrogenated oil, which is not good for digestion. Depression has become a widespread problem and research has linked certain nutrients found in foods, such as vitamin B, omega-3 fatty acids and olive oil, to a reduction in depression (Robson par. 1). Consumption of trans fats and saturated fats in fast food increases the risk of depression among consumers. Please note: this is just an example. Get a custom paper from our expert writers now.
