A few months ago, a new scientific paper discussing a link between mental stress and digestive trouble crossed my desk. I was immediately intrigued—partly because at the time I was stressed (it was during the holiday season, work was busy and my husband was traveling a lot on business), but also because at one time or another everyone feels taxed. This was information I knew you, our reader, could use!
And sure enough, once word got out among our staff, the whole office was buzzing: How does stress affect my gastrointestinal tract? And because I’m the nutrition editor, I was also asked, are there any soothing foods that I can eat?
I now can answer those questions—thanks to Karen Ansel, who researched and wrote about the topic in the March/April issue of EatingWell Magazine . Here’s what she found:
There’s a reason why when you’re upset, you feel a knot in the pit of your stomach. “The brain and the digestive tract share many of the same nerve connections,” says Douglas A. Drossman, M.D., a gastroenterologist and psychiatrist and co-director of the University of North Carolina Center for Functional GI and Motility Disorders in Chapel Hill. It’s because, in the womb, the nerves that eventually separate into the brain, spinal cord and nerves of the intestine all have the same beginnings and remain interconnected.
Mental stress delivers a one-two punch to our digestive systems. First it causes the release of cortisol and adrenaline, hormones that not only divert energy to your muscles (so you can fight—or flee!), but also slow digestion. For momentary bouts of stress, that’s a good thing (you want to use your energy to escape the bear, not digest your lunch), but when stress is chronic those same hormones can make your digestive system sluggish, leading to constipation. In addition, chronic stress can alter the release of neurotransmitters like serotonin, which promotes relaxation. And because 80 percent of your body’s serotonin is located in your gut, it’s no wonder that when too much is released it can keep you running to the bathroom, while too little can make you irregular.
Luckily, science suggests that, when stress strikes, reaching for certain foods can soothe your psyche and your GI tract. Here are three to get things back on track:
