In the 80s and 90s, food companies started making a lot of “ultra-processed foods“. These foods, like potato chips, frozen meals, soda, and fast food, have a lot of added sugar, salt, fat, artificial colors, and preservatives.
Currently, about 73% of the food in the United States is ultra-processed. But studies show that these foods can cause health problems like diabetes, obesity, and cancer.
Unfortunately, many Americans get more than half of their daily calories from ultra-processed foods.
Nicole Avena, a professor of neuroscience, says that ultra-processed foods can be addictive, just like drugs. It’s hard for people to eat just one potato chip.
In the early 2000s, Carlos Monteiro, a researcher from Brazil, studied how food is processed. He made a system to classify foods based on how much they are processed. Ultra-processed foods are in the highest category which means the food tastes good, is addictive, but doesn’t have good nutrition.
In 2018, scientist Kevin Hall did a study with 20 healthy adults. For two weeks, the adults tried two different diets. In one diet, they ate a lot of ultra-processed foods, and in the other diet, they ate mostly natural foods. The people ate 500 more calories per day when they were on the ultra-processed food diet and they felt hungrier.
This study showed that ultra-processed foods make people overeat. The food is made to taste good and trick our brains into thinking it doesn’t have many calories.
