A study from Tulane University has revealed a connection between the consumption of ultra-processed foods and a higher risk of hip fractures. These foods, which include items like hot dogs, snack cakes, and sodas, have been linked to various health issues such as cancer, diabetes, and heart disease. The research analyzed data from over 160,000 individuals in the UK Biobank database, finding that on average, participants consumed about eight servings of ultra-processed foods daily. For every additional 3.7 servings consumed, the risk of experiencing a hip fracture increased by 10.5%. This additional amount roughly equates to a meal of a frozen dinner, a cookie, and a soda.

Ultra-processed foods are typically defined as items containing ingredients not commonly found in home kitchens, such as chemical preservatives, high-fructose corn syrup, and artificial colors. These foods are usually high in calories but low in nutritional value. A 2023 estimate indicated that approximately 75% of the U.S. food supply falls under this category.
The study's findings also suggested that a high intake of ultra-processed foods is associated with decreased bone mineral density in areas like the upper femur and lumbar spine, particularly in individuals under 65 years old and those with a body mass index (BMI) below 18.5, categorized as underweight. Lu Qi, MD, PhD, a professor of public health and tropical medicine at Tulane University, stated that the results were expected, noting that the dependence of bone health on proper nutrition aligns with previous research linking ultra-processed foods to various nutrition-related disorders.
