Wow. You must have nothing better to do at 3 in the morning.
I looked it as not the nutritional value of the Cheetos that kept her alive so long and obviously that was not the only thing that she ate. I saw it as the 'joy' or satifaction of eating her favorite snack made her feel good and perhaps kept her going. People in the US do not just eat to stay alive. The eat because it make them feel good. If we ate to just live, then obesity would not be a problem because no one would be over weight and we would only eat for need not for pleasure.
There are a lot more people turning 100 years old these days. Doing a news story on plain jane turning 100 is not interesting to most. But add in a funny or twist or something unusual and that makes the sorry.
And if you are worried about what that message is sending to our kids, than the parents need to talk to them and explain the facts about nutrition and not rely on news stories or TV to raise them. We need to take responsibility to train our kids on how to live. Quit being so dang critical of everything.
