Here are the ultraprocessed foods you most need to avoid, according to a 30-year study

Studies have shown that ultraprocessed foods can have a detrimental impact on health. But 30 years of research show they don’t all have the same impact.
Eating ultraprocessed foods is associated with an early risk of death, according to a 30-year study — but different foods have different impacts.
Processed meats and sugary foods and drinks aren’t correlated with the same risks as ultraprocessed whole grains, for example, said lead study author Dr. Mingyang Song, associate professor of clinical epidemiology and nutrition at Harvard’s TH Chan School of Public Health.
The study analyzed data from more than 100,000 health professionals in the United States with no history of cancer, cardiovascular disease or diabetes. From 1986 to 2018, the participants provided information on their health and lifestyle habits every two years.
Every four years, they completed a detailed food questionnaire.
The group eating the least ultraprocessed food ate about three servings a day on average, while the highest averaged seven servings a day, according to the study published Wednesday in The BMJ journal.
Those who ate the most had a 4% higher risk of deaths by any cause, including a 9% increased risk of neurodegenerative deaths, the data showed.
Song described the correlation as “moderate,” noting that the connection was not equally strong among all kinds of ultraprocessed foods.
