A recent large-scale study found a connection between the intake of ultra-processed foods (UPFs) and an increased risk of chronic diseases. The research, published in the journal Family Medicine and Community Health, included data from almost 8.8 million adults across the Americas, Europe, Asia, and Oceania, with some follow-up periods extending up to 32 years.
Key Findings
Researchers discovered that consuming an additional 100 grams of UPFs daily was associated with:
- A 14% higher risk of cardiovascular events
- A 4% higher risk of cancer
- A 3% higher risk of death from any cause
- A 2% higher risk of metabolic syndrome or diabetes
Ultra-processed foods often include items like sugary drinks, processed meats, and packaged snacks. A 3½-ounce bag of corn chips exemplifies the portion size concerned in the study.
Increased Health Risks
Participants with the highest UPF intake also saw elevated risks of digestive diseases, depression, anxiety, obesity, cancer, and cardiovascular events. The study suggests that reducing UPF consumption and opting for minimally processed alternatives can aid in preventing chronic diseases.
“A diet built around whole, minimally processed foods is one of the best investments we can make in our long-term health,” stated Xiao Liu, the lead researcher, a cardiologist at Sun Yat-sen Memorial Hospital in China and a research fellow at Duke-NUS Medical School in Singapore.
Kelly Springer, a registered dietitian based in New York, concurs that UPFs crowd out healthier options. She suggests incorporating more real foods like fruits, vegetables, beans, and whole grains into your diet.
Diet Recommendations
Instead of focusing solely on reducing UPF intake, adding protein and fiber to meals and snacks can be beneficial. Suggestions include pairing an apple with peanut butter or meals featuring beans, chicken, or tuna with a side of fruits and vegetables.
Springer cautions that the study is observational and does not definitively prove that UPFs cause negative health outcomes, as it relies on self-reported diets that may not account for all lifestyle factors.
Despite these limitations, the study highlights the potential health risks associated with UPFs and reinforces the importance of a diet rich in whole, minimally processed foods.
