But as the experiment went on, researchers began encountering anecdotal evidence that surprised them. The people who moved out of poor neighborhoods were healthier. When they went back and measured the differences between people who got vouchers and people who didn’t, the results were remarkable: The people who got vouchers to move to low-poverty neighborhoods had significantly lower rates of obesity and Type 2 diabetes.

.. In much the same way, being late for school, unable to make your car payment, worried about where your next meal will come from, or feeling unjustly scrutinized because of your skin color aren’t immediate physical threats. But the brain still responds by signaling the adrenal glands to release cortisol. “Those energy substrates are still in high circulation so you can run away,” Hasson says. “But if you don’t, or can’t, run away, you’re always in this high-alert situation, whether or not you’re conscious of it.”
.. As part of its role in freeing up energy, chronic exposure to cortisol also increases cravings for high-sugar, high-fat foods, and increases the body’s resistance to insulin, the hormone that signals the body’s cells to absorb sugar.
