There’s now even more evidence that eating ultraprocessed foods is bad for your health.
A diet that has more cookies, chips, cakes, pizza, hot dogs and other salty and sweet goods – such as candy-filled grilled cheese sandwiches – can greatly raise your risk of chronic illness, a new analysis of more than 50 studies, including nearly 9 million adults, reveals.
An ultra-processed-heavy diet increased the risk of cardiovascular events, diabetes and obesity by nearly a quarter. It also raised the risk of depression and anxiety by 27 percent and suffering a digestive disease by 31 percent.
And every extra 100 grams of these foods a day elevated the risk of developing cancer by 4 percent, and the risk of death by any cause by 3 percent.
“In our modern society, our diet and food is maybe not safe … we should eat more vegetables and reduce the ultra-processed food to make us healthier,” Dr. Xiao Liu, lead author of the study and a physician at Sun Yat-Sen Memorial Hospital, told ABC News on Tuesday.

Past studies have shown that ultraprocessed foods affect the gut, promote inflammation tied to cancer and insulin resistance that leads to diabetes, the researchers said.
In addition, compounds that may form during food processing have been associated with a higher incidence of cardiovascular disease, they added.
How often people ate these foods was recorded in journals and questionnaires, though the researchers note that means their assessment relies on subjective information.

Ultraprocessed foods are made with sodium, added sugars and refined grains, as well as industrial ingredients that enhance taste and texture.
However, not all ultraprocessed foods are considered junk foods. For example, yogurt and hummus are better options.
Still, June research from Tufts University has revealed that people who ate more ultraprocessed foods had worse health outcomes — even after accounting for the overall nutritional quality of the foods.
“The findings suggest ultra-processed-food factors beyond nutrients – such as changes to foods’ cellular structure, loss of beneficial chemical compounds, additives and chemicals from packaging – may create health risks not addressed by traditional nutrition metrics or policies,” that study’s senior author, cardiologist Dariush Mozaffarian, director of the university’s Food is Medicine Institute, said in a statement.
