Negative Effects Of Eating Fast Food

                                                                

Fast food has a very high energy density. About 65 percent higher than a typical diet and twice as high as recommended healthy diets which makes us eat more than we otherwise would. Energy density refers to the amount of calories an item of food contains in relation to its weight. Foods with a high energy density confuse the brain’s control systems for appetite, which are based solely on portion size.

 British researchers from the Medical Research Council Human Nutrition Center and the London School of Hygiene and Tropical Medicine have determined that repeated eating at McDonald’s or KFC or Burger King, people are more likely to gain weight and become obese. This is because fast food not only contains many more calories than traditional food, but also is more likely to undermine normal appetite control systems.

 By eating a Big Mac and fries, the body consumes almost twice as many calories as you would if you ate the same weight of pasta and salad. Fast Food restaurants feed the obesity epidemic by getting people to eat many more calories than they need through persistent advertising.

 People get fat eating regular portion sizes, but since the food has a high energy density, people gain weight. In evolutionary terms, the human appetite was designed for low energy density foods. In other parts of the world where these foods are still the dietary staples, obesity is virtually non existent. Our bodies were never designed to cope with the high energy dense foods consumed in the West. That is a major reason why fast food in contributing to the major rise in obesity.

 Another fact is that fast food may speed up people’s risk of clogged arteries that can lead to heart attacks. Researchers at the Veterans Administration Medical Center in San Francisco have demonstrated that a certain type of fat, called oxidized fat, can accelerate the buildup of plaque in arteries. And many types of fast food such as hamburgers, pizza and French fries are loaded with oxidized fat. The conclusion is fast food meals are high in saturated fat and low quality carbohydrates, white bread and lots of soda. Our bodies require fiber and more healthful types of fats. Fast food represents a dietary pattern that is the opposite of what is recommended for a healthy body.

Fast food nutrition should make up a minimal part of a healthy diet. Fast foods and junk foods are high in fat, sodium and sugar, which can lead to obesity and a range of attendant health problems, including diabetes, heart disease and arthritis. Here are the facts about how excessive junk food consumption affects your body.

Fast Food Affects Your Energy Levels

Fast food doesn’t contain the nutrients your body needs to stay healthy. As a result, you may feel chronically fatigued and lack the energy you need to complete daily tasks. The high levels of sugar in fast food puts your metabolism under stress; when you eat refined sugar, your pancreas secretes high amounts of insulin to prevent a dangerous spike in blood sugar levels.

Because fast food and junk food don’t contain adequate amounts of protein and good carbohydrates, your blood sugar levels will drop suddenly after eating, leaving you feeling grumpy, fatigued and craving sugar.

Fast Food Contributes to Poor Performance and Obesity

Fast food contains large amounts of fat, and as fat accumulates in your body, you’ll gain weight and could become obese. The more weight you gain, the more you’ll be at risk for serious chronic illnesses such as diabetes, heart disease and arthritis. You could even have a heart attack.

The high levels of fat and sodium in junk food can cause high blood pressure or hypertension. Excessive dietary sodium can also have a negative effect on renal function, even leading to kidney disease.

In the short term, high levels of dietary fat lead to poor cognitive performance. You’ll feel tired and have trouble concentrating because your body might not be getting enough oxygen.

Fast Food Can Damage Your Liver and Your Heart

The high levels of fat and sodium in junk food and fast food can contribute to heart disease by raising blood cholesterol levels and contributing to arterial plaque build up. The high levels of trans fatty acids found in many junk foods and fast foods can lead to fatty liver deposits, which, over time, can cause liver dysfunction and disease.

Fast Food Can Lead to Diabetes

Over time, the high levels of sugar and simple carbohydrates in junk food can lead to type 2 diabetes. This occurs because eating too much sugar puts your metabolism under stress; when you eat a lot of refined white sugar and simple carbohydrates, your body has to pump up insulin production to prevent a dangerous spike in blood sugar levels.

Because Fast food doesn’t contain the protein or complex carbohydrates that your body needs to maintain consistent blood sugar levels, your blood sugar levels will drop suddenly soon after eating. You’ll crave sugar and likely end up eating more junk food.

Over time, this stress damages your body’s ability to use the insulin secreted by your pancrease. A healthy diet can help maintain your body’s insulin sensitivity.

Even in the short term, eating too much Fast food can make you feel really uncomfortable. It can lead to mood swings and constipation, and lower your energy levels so that you lack interest in the exercise you need to burn off those extra calories.
