1. fast-food has a very high energy density. About 65 percent higher than a typicaldiet and twice as high as the recommended healthy diet to eat more, than we wouldotherwise. Energy density is the amount of calories that contains an element of foodcompared to its weight. Food with a high energy density confuse the brain control systems for the hunger, to be alone on the portion size.
2. British researchers of the Medical Council Research Center for human nutrition andLondon School of hygiene and tropical medicine have determined that reviewedeating at McDonald or KFC or Burger King, people are more likely to gain weight andbecome obese. This is more calories than traditional food as fast food includes notonly many, but also tend to endanger the normal appetite to control systems.
3. eating a big Mac and fries, which consumed almost body would be twice as manycalories as you, if you use the same weight eating pasta and salad. Fast Food restaurants, feeding the obesity epidemic by getting people to eat more calories thanthey need by advertising.
4. McDonald and Burger King, KFC menu items by using the nutrition data from Web pages of fast-food restaurants, found that if we do not reduce eating foods with highenergy density so we get the size of the part much more calories than we need.Today's society has an innate ability to detect weak foods with a high energy density.Food intake is estimated from the size of the part, a fast-food eating, contains manymore calories than a portion of similar size on a healthy meal. The conclusion is thatwe all eat before too much.
5. people get fat eat normal portions, but given the fact that the food has a highenergy density, increase in weight. The human appetite was developed fromevolutionary for food of low energy density. Obesity is still in other parts of the worldwhere these foods dietary staples are virtually non-existent. Our bodies were neverdesigned to handle high energy dense foods eaten in the West. Is the main reasonwhy fast food as a contribution to the rise in obesity.
6. a further problem is that people risk blocked this fast-food can accelerate arteries,which can lead to heart attack. Researchers at the Veterans Administration MedicalCenter in San Francisco showed that a certain type of fat, can called oxidized fats,accelerate the accumulation of plaque in the arteries. And many kinds of fast food likeburgers, pizza and fries with fat oxidized are loaded. The conclusion is that fast food meals are high saturated fat and low carbohydrates, white bread and much soda. Ourbodies need more healthy types of fat and fiber. Fast Food is a dietary model, which isthe opposite of what is recommended for a healthy body.
