This Is Why You Crave Sugar When You’re Stressed Out

Here’s something that won’t come as a surprise to anyone who has ever devoured a pint of Rocky Road after a miserable day at work: Researchers at the University of California-Davis recently found that 80 percent of people report eating more sweets when they are stressed. Their new study, published in the the Journal of Clinical Endocrinology & Metabolism, offers a possible explanation.

Sugar, the researchers found, can diminish physiological responses normally produced in the brain and body during stressful situations. With stress levels on the rise, this could explain why more people are reaching for sweets.

The three-phase study involved 19 women, ages 18 to 40, who spent three days on a low-sugar diet at the research facility. Saliva samples and MRIs were taken and stress was induced through timed math tests. After being discharged, over the course of 12 days, the women consumed sweetened drinks three times a day. Half had beverages sweetened with the artificial sweetener aspartame, while the rest had drinks sweetened with real sucrose. This phase was followed by an additional three-day stint at the facility during which MRIs and saliva samples were taken again.

After the 12-day period, the group that had sucrose-sweetened beverages showed higher activity in the left hippocampus (an area of the brain responsible for learning and memory that is sensitive to chronic stress) and significantly reduced levels of cortisol (the hormone released in response to stress) compared to those who had artificially sweetened beverages.

While this study was one of the first to show that sugar can reduce stress responses in humans, it followed up on previous studies that found similar conclusions in animal subjects. The researchers noted the need for future research—especially on whether long-term sugar consumption has the same effect.

“The concern is psychological or emotional stress could trigger the habitual overconsumption of sugar,” lead author Kevin D. Laugero told Science Daily. Not exactly great news for those of us who enjoy eating our feelings.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
