The Causes and Effects of Eating Junk Food
Despite regular eating of junk food having a link to obesity and other chronic health conditions, many people still choose junk food sources over healthy and wholesome food sources. Junk food is cheap and easily available. However, there are psychological factors that affect the choice of food one prefers. Many people have internal motivators that predispose them to choose junk food as a meal.
Choice convenience is one of the factors that affect the kind of food people want. With limited time available people prefer faster and easier options. Real healthy and wholesome food costs one time and kitchen equipment, unlike fast food hamburgers than are typically served within minutes of ordering. The urge for fast food becomes a habit and with time, it becomes a necessity to keep up with the fast-paced life.

Most people will prefer junk food to real food as a means of easing stress. A fast-paced culture leads to high levels of stress and anxiety. Elevated levels of stress, in turn, expend the energy available in the body, which leads to stimulation of hunger for calorie-dense foods. Calorie-dense foods are the fatty and sugary junk foods.

Diets rich in sugar and fat suppress the ability of the brain to learn and form memory.
Depression can also be caused by excessive intake of fatty and sugary products. Such poor diets cause chemical changes in the brain such that one becomes more dependent on them. If the taking of the junk foods is discontinued, one suffers from withdrawal symptoms and eventually stress and depression which one calms down by going back to the junk foods. It makes one unable to handle stress (Gibson, Stanley, and Edward, 2015).
The risk of dementia is one of the latest and scariest discoveries associated with excessive consumption of fast food. Insulin is produced in the pancreas, and it helps in the transportation of glucose to fuel the body. It is also manufactured in the brain and contributes to carrying signals between forming memories and nerve cells. Too much junk food increases the level o...
