Consumption of fast food has been associated with 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 when consumed in excessive quantities. Increasing rates of obesity and depression in countries like the United States and the United Kingdom can be attributed to the increased consumption of fast food (Rosenheck 535).

In the United States, the number of fast food outlets has increased significantly, from 30,000 in 1970 to more than 233,000 in 2004 (Rosenheck 535). I believe that fast food has a negative impact on consumers' physical and emotional well-being. The portion sizes of fast food meals are often much larger than the average calorie intake of a home-cooked meal for an adult. This excess calorie consumption can lead to weight gain. Additionally, fast food restaurants typically serve predetermined portions that contain more calories 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 consume 31% more energy and men consume 56% more energy when eating a 6- or 12-inch sandwich, respectively (Ledikwe, Ello-Martin, and Rolls 906). Studies of fast food snacks have also found 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 the increased caloric intake of consumers. Fast food is also high in unhealthy fats. While naturally occurring fats are essential for digestion, absorption, and transport of fat-soluble vitamins and essential elements, the fats found in fast food are primarily saturated fats and trans fats. An adult man 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 stay healthy (Rosenheck 536). However, just one bite of a restaurant burger contains almost 10g of saturated fat, which exceeds the recommended intake for men. The high fat, salt and sugar content of fast foods leads to an increase in harmful bacteria, causing indigestion. Fast foods like 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 and omega-3. fatty acids and olive oil, to reduce depression (Robson par. 1). Consumption of trans fats and saturated fats in fast foods increases the risk of depression among consumers. Keep in mind: this is just a sample.
