1)does our society promote / encourage an unhealthy attitude toward food.
2)should fast food companies be held responsible for the obesity problem in the us?

If you are asking for those to be answered;

No the society does not always promote unhealthy food choices. In fact, many organizations such as American Heart Association and World health organization have done many activities to provide Americans with health food. Schools have also adopted a healthy food choice for lunch and make sure that the proportions are even. As for fast food companies, it really isn't necessary to blame them for obesity. A persons poor food choice usually starts when they are young and not introduced to the proper nutritional needs. This caused them to create a mind set in which they food they eat is deemed healthy and normal to them. Obesity and health problems are the cause of under nutrition.

I hope this helps. I've taken health 4 times. So I'm going off of what I know. Good luck.
