Remember to avoid UPFs or you may have memory problems
The list of health hazards associated with highly and ultra-processed foods (UPFs) is getting longer and longer. From cardiovascular woes to cancer, Type 2 diabetes, wheezing, obesity, dementia, depression and premature death, these nutrition-stripped edibles (I hesitate to call them foods) are devastating the health of Americans -- and folks all around the globe.
Well, here's another risk you're taking when you indulge: A lab study in Brain, Behavior, and Immunity found that UPFs damage a part of a rat's brain, the amygdala, that has control over emotional memories -- especially those associated with a dangerous experience. (It's in our brains, too). And older lab animals experienced more damage.
The researchers found that eating highly processed food for as little as three days (!) was all it took. It was the extreme lack of fiber in processed foods that had a direct impact on the amygdala -- and it didn't matter if the diet was high fat, high sugar, low fat or low sugar. The researchers add that this damage is particularly dangerous because remembering that something is risky helps avoid future trouble.
If you are getting 53% or more of your calories from processed foods (that's the average for all ages in the U.S.), it's time to remember what's best for you: natural, whole foods with no added sugar. And make sure to avoid ingredients you cannot pronounce and red and processed red meats.
