We all know that eating ultraprocessed food can make you overweight, but did you know it can actually make you depressedĀ š? Ā A largeĀ study from Harvard Medical School was just published in JAMAĀ this month! Ā This was a large cohort study on over 31,000 women age 42-62. Ā After following these women for 14 years, they concluded that the participants with a higher intake of ultraprocessed food had an increased risk of depression! Ā This was based on symptoms reported on questionnaires as well as new antidepressant useĀ š. Ā
Sadly, the Standard American DietĀ šĀ is loaded in ultraprocessed foods due to convenience and palatability. The study looked at the following categories of food: ultraprocessed grain foods, sweet snacksĀ š¬, ready-to-eat mealsš, fats and sauces, ultraprocessed dairy products, savory snacks, processed meatĀ š, beveragesĀ š„¤, and artificial sweeteners. Ā Can you guess which category was the worst for mood?
It turns out that artificial sweeteners and artificially sweetened beverages were associated with the greatest risk of depression. Ā
This is no surprise as ultraprocessed foods negatively impact our gut microbiome. They cause inflammation in the lining of our gut and feed bad bacteriaĀ š¦ Ā and yeast to overgrow (dysbiosis). Ā We make 80% of our serotonin (happy brain neurotransmitterĀ š) in the lining of our gut, which is why we refer to the gut as the second brainĀ š§ . Ā If our gut is unhealthy, so is our mood. Ā
The good news is that by cleaning up our diet and eating more phytonutrient-rich plant foods š«, we can restore a healthy gut microbiome and see a positive change in our mood!
