Question

Using the information in your text explains why the U.S. is the most obese nation in the world, even though Americans are not genetically different from people in other nations. Why is obesity genetically predisposed in individuals? Why is the need to belong genetically predisposed? What evidence supports this idea?

Answer 1

Obesity can be genetic as well as the environmental factor, food habits also contribute to the increased rate of obesity in people. It also depends on a person's behavior and their habit of excessive eating and the advantages of food delivery at any time can encourage this type of unhealthy practices. American government and their farm policies can be responsible for this and various kind of facilities regarding fast food and those multiple restaurants grocery stores that sell food with extra calories may increase extra fondness for fast food but U.S government also introduced some policies to people for encouraging them to follow a homemade healthy diet and about eating fruits and vegetables on a daily basis. It also changes the patterns of behavior in people and their immune system will prevent them from getting the disease even if it is genetic. Unless it is inborn abnormality or one has excessive eating disorder or never-ending hunger. In such cases parents should be cautious about their health. weight gaining problem can be controlled at initial stages by practicing physical activites. Cancer, tumor, diabetes these are some obesity-related diseases. Otherwise an individual is responsible for his/her health. No store or restaurants can be blamed for this.

Genetically predisposition means one's higher tendency to get a genetic disease but there's no such gurantee that one with family history of several diseases will be affected surely, the specific gene has to be present in that person. Like a person with BARD1 gene is less likely to get breast cancer, doesn't matter if the person has cancer history still she will be safe. In America the increased rate of having twins points at some potential SNP. Quite old aged mothers face this situation mostly. Different people with different genes get juxtaposed and the mixed up genes usually lead to this kind of obesity.

Evidence would be that it is found in a research that using chemical drugs or processed food can lead to liver damage or it can grow cancerous symptoms in people. Where risk factors are there reasons of variation in public in disease may be ascribed deeply to genes, while often the best methods of prevention or cure would be lchanges of lifestyle by bringing changes into environmetal growth.
