Fast foods are those that can be prepared quickly and easily and is sold in restaurants and snack bars as a quick meal or take out. We often find ourselves succumbing to the temptations of that perfect cheesy pizza and the even better cheeseburger with fries on the side. We often fail to realize the fast food is nothing but a concoction of harmful and health-damaging chemicals. One of the reasons why we eat fast food is that we are too busy to cook and fast food are quick and so easy to get. Fast food is also inexpensive. Who wants to spend a lot of money when you can have cheaper alternatives? Another factor affecting our fast food consumption is psychological advertising. Fast food advertisements showing mouth-watering burgers, pizzas and fries are rampant. Advertising plays a huge role in how society is run today, and that includes which foods we eat. Studies have found that those people who think fast food is convenient, and those who dislike cooking, were considerably more likely to eat fast food. While this food may be quick, easy and inexpensive, they’re all processed foods and are not the healthiest options for your diet. Avoiding those foods that consist mainly of artificial or highly processed ingredients will go a long way toward improving your health. Here are the reasons why you should avoid fast food: #1. Fast food makes you fat. One of the main reason why you should avoid fast food is because it makes you fat. Studies have found that eating fast food is linked to weight gain and insulin resistance. In others words, fast food makes you fat and increases your risk of type 2 diabetes. With all the fat, processed starch and calories, fast foods add nothing but unwanted weight to your body. #2. It can increase the risk of kidney disease. Salt is used as a preservative in foods. The high salt and fat content in fast food increases blood pressure and adversely affects the functioning of the kidneys. #3. It increases the risk of cancer. Fast foods are high in fat, sugar, and salt, which can lead to an increased risk of cancer. Studies have proven that there is a direct link between the amount of fatty, fried food that people eat and the incidence of cancer. #4. Other medical problems. In addition to increased risk of type 2 diabetes, kidney disease, and cancer, research has shown that eating fast food also increases cholesterol levels in the body and affects the heart and other organs in adverse ways. Apparently, the momentary pleasure of eating fast food is clearly not worth the diseases it is exposing you to. #5. It weakens the immune system. Research shows that over-indulgence on foods full of sugar, salt and fat may be ruining our immune systems. The food and lifestyle choices can permanently change the balance of bacteria in our bodies and can weaken the immune system. Eating too much of fast food prevents the body from developing a strong immune system and it easily falls prey to diseases. Fast food not only exposes you to diseases but also kills the body’s ability to fight them. #6. It affects brain functioning. A study has shown that children who eat fast food tend to score lower in math, science, and reading. It is believed that the bad fats in fast food replaces the healthy fats in the brain and so impairs brain functions. This is due to the fact that fast foods lack in iron content which is an important ingredient for the development of our brain cells. #7. Low price means low quality. Fast food is inexpensive. Why? It is because fast food chains use the cheapest possible ingredients. This means it has very limited nutritional value and a lot of salt to create some flavor. The human body needs appropriate amounts of proteins, carbohydrates, vitamins, minerals and other important nutrients to stay healthy. But fast foods mostly only contain carbohydrates and starch.
