I would sure like to know where you live, so I could move there.
The bottom line is the reasons "poor people are overweight" are:
Lack of money
Lack of education
Lack of shopping options
Lack of refrigeration, stove, oven and storage space
Lack of transportation
It is just a Fact that prepackaged high carb food is cheaper, easier to prepare, can be purchased anywhere, requires little refrigeration, limited cooking resources and stores easier. So it can be purchased with or without transportation.
So does this clear the question up for everyone?
Well I guess I should ask the same question; where do you live?
Here is a quote from The Economic Research Service of the United States Department of Agriculture:
"How Much Do Americans Pay For Fruits And Vegetables?- One argument for not consuming fruits and vegetables is that they are too expensive, especially when fresh. Yet among 154 forms of fruits and vegetables priced using ACNeilsen Homescan data, more than half were estimated to cost 25 cents or less per serving. Consumers can meet the recommendation of three servings of fruits and four servings of vegetables daily for 64 cents. The related product data is a collection of spreadsheets that contain all the data used in the report and are presented to show exactly how ERS arrived at the costs per serving figures."
I still cannot post links so you will have to look up the USDA ERS yourself.
Food in America is mightily abundant and by global standards very, very reasonable priced as well. Two facts that as an American you should be very proud of.
While I do not disagree that employment opportunities, shopping, housing and transportation play a role in American poverty, I still believe the major issue with American obesity in low income earners is education. Notice how I distinguish between the two. I believe that there is a link between poverty and obesity, however I do not believe that if you solve the poverty issue you will solve the obesity issue at the same time. They are not the same issues.
It's too simple to blame such a complicated problem on one or two items, like high carb prepackaged food or fast food restaurants.
It's not the food, it's how you eat it. And knowing how to eat is a matter of education.
As well I do not understand your statement "
So it can be purchased with or without transportation." Given then, that one can purchase mac and cheese without transportation; one should then be able to purchase a potato or a tomato without transportation. I do not see the difference or the point you are trying to make.
As well, I would tell you that nothing in the world is easier to prepare then a fresh fruit.
Cheap ramen noodles require more time, effort, energy and concentration then eating a whole apple or fresh tomato.
In summation, my response to your question “So does this clear the question up for everyone?” is no.
Keep in mind this is my opinion, I will let you seek out the facts for yourself.
