Your Diet and Depression Are More Connected Than You Think

According to the World Health Organization (WHO), approximately 5.7% of adults, or 332 million people, have depression. It's a debilitating disorder that isn't always taken seriously by the public because it doesn't necessarily manifest in a "physical" way.

While medication is a common treatment option, a recent study set out to see if a basic lifestyle intervention could help instead. Researchers wanted to know if having healthy meals delivered to your door could help reduce depression symptoms, and whether that works better than just giving people nutrition advice to follow on their own.

Thirty-one adults with moderate-to-moderately severe depression were split into two groups for 2 weeks. Both groups got guidance on eating more minimally processed foods, but one group actually had healthy meals delivered to their door.

Both groups saw improvement, but depression symptoms improved more in the meal delivery group. The meal delivery group showed a large, statistically meaningful reduction in depression scores. The guidance-only group improved too, but not significantly.

The results make logical sense for a number of reasons. The first is that some people use junk food as a coping strategy to deal with depression. While it may provide short-term relief, it can also perpetuate depression symptoms. Once the acute pleasure ends, you may feel guilty for eating so poorly.

The other reason is the impact nutrition has on mental health. Getting adequate vitamins and minerals, as one would from minimally processed foods, can have a tangible impact on mood and energy. Having three meals a day delivered to your home also provides structure and routine.

With that said, it's important to note that this was a small study, with only 31 total participants. The meal delivery only lasted two weeks, so it was also a short-term study. But the results are still encouraging. Having meals delivered makes it easier, especially since depression itself causes fatigue and low motivation that make cooking hard. This approach could complement standard depression treatments like therapy or medication, or serve as an accessible first step for people who aren't yet receiving treatment.
