What is obesity? According to the definition of obesity in the United States of America Centers for disease control and prevention, obesity and overweight are described as : Both labels for ranges of weight that are
greater than what is generally considered
healthy for a given height. The terms also
identify ranges of weight that have been
shown to increase the likelihood of certain
diseases and other health problems(United
States of America Center of disease control
and prevention, definition "Obesity").
Moreover, definitions of obesity of adults
and teens are different. As for adults, obesity ranges are determined by a number calculated with weught and height which is called the "Body mass index" (BMI) (United States of America Center fot disease control and prevention). BMI can show how fat or obese the person is. For example, if an adult who has a BMI between 25 and 29.9 is considered as overweight and has a BMI over 30 is considered as obese. As a healthy adult, their BMI will be between 18.5 and 24.9. As for teens and children, the method of measuring BMI is different. The BMI of a child need to be compared with other children at that age-range so that they can account the differencees in body fat.
The number of obese adults in the United States has been increasing in the recent years. According to studies, the number of obese adults in the States increased 30% from 2003 to 2009 (Hootman). In 2009, thirty-three states had a prevalance equal to or greater than 25%. Nine states( Alabama, Louisiana, mississippi, Missouri, Oklahoma, Tennessee, Kentucky, West Virginia and Arkansas) had a prevalence of obesity equal to or greater than 30% (United States of America Center of disease control and prevention). As for children, the number of obesity had been tripled in the past thirty years(United States of America Center of disease control and prevention). What is the cause of the obesity problem in the United States? What so special about the Americans? This can be Chan 3
explained by the uprise of the fastfood industry.
The fast-food industries in the America have become more and more popular in the past 30 years. They were well known with their cheap price, quick service and tasty meals. Despite all these advantages, fast-food does not do any good to our bodies ( Obesity in America). Most of the fast-food contains lots of salt and sugar and with high content of fat and calories. According to studies, a normal adult should not have more that 65 grams of fat or 2000 calories a day(Obesity in America). However, one meal from Burger King (a hamburger and french Fries) has already contain 50 grams of fat and 2000 calories. This shows that we have already absorb enought fat and calories in that day after having only one single fast-food meal( Obesity in America).
The another cause of obesity is the limited access to healthy and affordable foods. Millions of Americans live in areas that are lacking convenient access to fresh and healthy foods (White House Task Force on Childhood Obesity Report to the President). Most of these people are low-income or poor. From this we can see how poverty affects health.
