According to experts, these highly processed junk foods are just as addictive as heroin, nicotine, or cocaine. And overtime, they can prove to be just as deadly.
From The New York Post:
A new analysis of 281 studies across 36 different countries has uncovered that a staggering 14% of adults are hooked on UPFs.
The finding is shocking, given that UPFs — think: sausage, ice cream, biscuits, soft drinks, and sugary cereals — have previously been linked to cognitive decline, cancer, psychological distress and even an early death.
The analysis was led by University of Michigan professor Ashley Gearhardt, who previously created the Yale Food Addiction Scale by applying the same criteria that experts.
That criteria includes uncontrollable and excessive consumption, cravings, and continued intake despite potential negative health effects.
“The combination of refined carbohydrates and fats often found in UPFs seems to have a supra-additive effect on brain reward systems, above either macronutrient alone, which may increase the addictive potential of these foods,” Gearhardt and the study’s authors wrote in their new findings, published in The BMJ.
“Many UPFs for many people are addictive,” author Chris van Tulleken told The Guardian in an article about the new study. “And when people experience food addiction, it is almost always to UPF products.”
But exactly why largely remains a mystery to experts, some of which believe that it may not be a single ingredient that makes candy or crackers addicting — unlike nicotine in tobacco — but rather the contraindications of multiple.
Naturally sourced foods tend to have more carbohydrates or more fats, but not high levels of both, whereas UPFs have disproportionately higher levels of both.
If an apple has 55 kcal from carbs and less than 2 kcal from fat, a chocolate bar as 237 kcal from carbs and 266 kcal from fat.
Past research has also found that sugary or fatty foods make healthier alternatives less appealing, and the brain rewiring could have health-related consequences, such as over-indulging and weight gain.
Eating ultra-processed foods triggers a rush of dopamine followed by a sudden drop-off, resulting in an endless cycle of craving, getting a fix and crashing — similar to that of someone who is addicted to alcohol or drugs.
Well, I think we can certainly use this research as part of the reason why the United States is plagued with obesity.
After all, about half of our diets are composed of these highly processed, addictive foods.
It's critical that our culture recognizes how harmful these foods are and stops consuming them. Once these brands see that we're not buying these products, then real change can finally occur.
