It's hilarious, 100 years ago people would laugh at such "hardships". Food availability isn't a problem in the U.S. for all but the extreme outliers. Now, education about nutrition is very likely a problem, but even the poorest of the poor can readily get the nutrition they need if they knew what they needed, but obviously even our rich don't understand nutrition.
The harshest measurement on the chart was someone who didn't eat for a full day over a 3 month period. I fast for many days at a time _because_ it's healthy. Our ancestors did not eat three meals a day and as a result our bodies are extremely adept at having irregular eating schedules.
We have an obesity epidemic in our poorest demographic. That says about everything that needs to be said, if you ask me.
