At a time when Americans consume more than half of their daily calories from ultra-processed foods, there is increasing evidence that eating too many of these foods can make us sick.
A study published in the British Medical Journal finds people who consume high amounts of these foods have an increased risk of anxiety, depression, obesity, metabolic syndrome, certain cancers including colorectal cancer and premature death.
The data come from more than 9 million people who participated in dozens of studies, which researchers analyzed as part of umbrella review.
“Taking the body of literature as a whole, there was consistent evidence that regularly eating higher – compared to lower – amounts of ultra-processed foods was linked to these adverse health outcomes,” says study author Melissa Lane, of Deakin University in Australia.

The U.S. diet is deadly. Here are 7 ideas to get Americans eating healthier
Ultra-processed foods are abundant in our food supply. Among the most common are highly refined breads, fast food, sugary drinks, cereals, cookies, and other packaged snacks. They are often high in salt, sugar, fat and calories and low in fiber and micro-nutrients such as vitamins.
The Dietary Guidelines for Americans recommend filling half our plates with fruits and vegetables, and eating plenty of whole grains, and not too much of the refined grains found in ultra-processed foods.
One telltale sign that a food is ultra-processed is if its ingredient label includes substances you would not find in your own kitchen such as high-fructose corn syrup, hydrogenated oils, hydrolysed protein, or additives such as artificial colors, flavor enhancers, emulsifiers, anti-caking agents and thickeners.
