A recent meta-analysis conducted by the University of Washington indicates that consuming processed food may pose health risks. After examining 77 studies, researchers found a connection between the consumption of processed meats, sugary drinks, and trans fatty acids and an increased risk of developing type 2 diabetes, ischemic heart disease, and colorectal cancer. Lead author Demewoz Haile emphasized that even small habitual amounts of these foods can be detrimental to health and should not be part of a daily diet. The study suggests that there is no safe level of consumption for these food groups.
Specifically, the researchers discovered that consuming as little as 0.6 to 57 grams of processed meats per day could increase the likelihood of developing type 2 diabetes. Similarly, consumption of 0.78 to 55 grams of processed food per day was associated with a heightened risk of colorectal cancer. The study also highlighted the impact of sugar-sweetened beverages, indicating that drinking between 1.5 and 390 grams per day could elevate the risk of type 2 diabetes and ischemic heart disease.
Trans fatty acids were also scrutinized, with the study revealing that their intake was linked to a higher risk of ischemic heart disease. The researchers urge individuals to limit or eliminate processed food consumption based on these findings, noting that lower exposure levels can still increase the risk of adverse health outcomes. This analysis, published in Nature Medicine, underscores the importance of reducing processed food intake to maintain overall health.
“In an interview with Fox News Digital, Haile cautioned against the consumption of processed meats, sugary drinks, and artificial trans fats. He emphasized that individuals who regularly consume these foods, even in small quantities, should be mindful of the heightened risk of chronic diseases. Haile acknowledged that the primary limitations of the study are related to the assessment of dietary intake. He explained that most studies included in the analysis relied on food frequency questionnaires, which can introduce measurement errors due to difficulties in recalling long-term intake.
Furthermore, Haile noted that some studies only assessed food consumption at the beginning of the research, potentially not reflecting the participants’ future dietary habits accurately. The study found an increased risk of ischemic heart disease when trans fatty acids accounted for 0.25% to 2.56% of daily energy intake. However, the research only examined a limited set of health outcomes for each dietary risk factor, possibly underestimating the overall health impact of these foods. Haile stressed the need for high-quality research to strengthen evidence and reduce uncertainty.
Dr. Nick Norwitz, M.D., PhD, a clinical researcher and metabolic health educator, commented on the study, noting a consistent association between higher processed meat intake and poor health outcomes. However, he highlighted that these are associations and not necessarily causal relationships. Norwitz pointed out that the quality of evidence was graded as ‘weak,’ citing the grouping of various foods within a single category as a limitation. He emphasized the importance of conducting more research to confirm the claims of the meta-analysis.
While acknowledging the potential negative health effects of processed meat, Norwitz suggested that further research is needed to validate the study’s findings. He remarked that items like office donuts or sodas likely pose a greater metabolic risk than a slice of deli turkey. The American Association of Meat Processors (AAMP) responded to the study, expressing the need for additional research to clarify the reported associations. The study defined processed meat as any meat preserved through smoking, curing, salting, or the addition of chemical preservatives.

The study suggests that consuming just one hot dog a day may increase disease risk, though some experts raise concerns about the evidence and call for further investigation.
