A recent study published in Family Medicine and Community Health indicates that increased consumption of ultra-processed foods is associated with higher health risks, including mortality. The research, which reviewed over 50 studies involving nearly 9 million adults globally over a period of 2 to 32 years, found significant correlations between ultra-processed food intake and various health issues, such as heart disease, strokes, obesity, diabetes, depression, anxiety, digestive problems, and cancer.

Maya Feller, a registered dietitian, explained that ultra-processed foods often contain high levels of added sugars, salts, and fats, making them highly appealing. Common examples include packaged snacks, processed meats, cookies, cakes, sugary beverages, and many ready-to-eat meals. Dr. Xiao Liu, the lead author of the study and a physician at Sun Yat-Sen Memorial Hospital, emphasized the public health implications of ultra-processed food consumption.
The findings revealed that the risk of cardiovascular disease, the leading cause of death in the U.S., increased by 24% with higher ingestion of ultra-processed foods. Each additional 100 grams consumed per day raised heart disease risk by 14% and blood pressure risk by 11%. The risk of metabolic diseases also rose, with diabetes risk increasing by 24% and obesity risk by 23%. According to the CDC, more than 100 million Americans live with obesity, and over 22 million experience severe obesity, while the average American derives more than half of their daily caloric intake from ultra-processed foods.
Feller noted the distinction between processed and ultra-processed foods, using fresh apples as an example of minimally processed items. While some foods undergo benign processing, such as freezing or canning without added preservatives, those with significant additives fall into the ultra-processed category. To make healthier choices, consumers are advised to closely examine ingredient lists, ensuring that products reflect their primary ingredient without undue additives.
For those seeking to limit ultra-processed foods without incurring high grocery costs, options like frozen and canned vegetables or lower-sodium canned goods are recommended. Feller also emphasized the importance of education and modeling healthier eating habits for children, encouraging family meals and conversations about nutrition as effective strategies.
The study suggests that individuals need not completely eliminate ultra-processed foods but could benefit from reducing their overall intake. Feller encouraged people to gradually replace a few commonly consumed ultra-processed items with whole or minimally processed alternatives. Dr. Liu reiterates the message that improving dietary habits, particularly through increased vegetable and fruit consumption, can lower the risk of various health conditions.
