Ultraprocessed foods fuel addiction and raise disease risk in United States

Research shows a growing number of Americans meet clinical criteria for addiction to ultraprocessed foods (UPFs). 14% of older adults and 21% of women aged 50‑64 in the United States are classified as addicted, according to the Yale Food Addiction Scale. Scientists say manufacturers manipulate sugar, fat, salt and additives to create highly rewarding products.

Separate epidemiological studies link high consumption of UPFs to serious health outcomes. One study found a 58% higher risk of dementia and a 46% increase in cognitive impairment among adults who ate the most UPFs daily. A meta‑analysis reported that processed meats, sugary drinks and trans fats raise the risk of type 2 diabetes, heart disease and colorectal cancer, with no intake level proved safe.
